Current StreamBase Release Notes

These are the release notes for the TIBCO StreamBase® component of TIBCO® Spotfire Data Streams 10.4.1.

New Features

TIBCO® Spotfire Data Streams 10.4.1 adds the following updates and new features:

Oracle LogMiner Adapters Added

This release adds the following two adapters, which when used together, allow a StreamBase application to monitor changes to an Oracle 12c and later database using Oracle LogMiner:

These adapters are illustrated in a sample.

WITSML Operator Now Includes Data Output Options

The WITSML Log Data Converter operator now has an Output Type option to output data as a list of key-value pair tuples. This new option is designed to enable more generic data use.

Web Server Adapters Now Support SSL for Both HTTPS and wss

The Web Server Request and Response adapters were updated to support SSL for both HTTPS and wss.

WebSocket Client Adapter Now Supports wss

The TIBCO StreamBase® Read Adapter for WebSocket Client now includes an Advanced tab to support wss configuration.

Python Operators Enhanced

The Python operators were enhanced as follows:

  • The Python Operators now support pulling artifacts from a running TIBCO Artifact Management Server, which is a separately installed product. See the operator page for details.

  • The operators support loading models stored as resources in StreamBase projects. See Running the P04-Script-Resource Sample in the Python sample page, which demonstrates three ways to load a Python script.

  • To improve troubleshooting, the Python and Python Instance operators now provide more error message details when deserialization of a given object fails.

Generated Log Messages for Initialized Default Availability Zone Improved

The number of log messages generated when the default availability zone is initialized are both significantly reduced and made clearer.

Stop Node Error Message Clarified

When a node stop is requested, but some of its configuration cannot be deactivated, the error message that appears now includes the path of the engine log relative to the node directory.

New Options Added to epdev Command for Maven Artifact Management

Three new clean-related arguments and the maven-home option were added to the epdev command for Maven artifact management and cleanup. See the epdev reference page or epdev --help for further information.

Oracle JDK Version Updated

The Oracle JDK version bundled with StreamBase and Live Datamart is now JDK 1.8.0_u191.

StreamBase Runtime Now Supports Amazon Linux 2

The StreamBase Runtime now supports the Amazon Linux 2 operating system. For StreamBase support details, see this page.

StreamBase Studio Now Supports macOS 10.14 Mojave

Studio now supports macOS 10.14 Mojave as a development environment. However, Mojave's dark mode is not supported because of Eclipse compatibility issues. When first selecting the Open StreamBase Command Terminal Here feature in Studio, you are prompted for permission to control the terminal.

Oracle VM VirtualBox 5.2 Now Supported for Runtime Deployments

StreamBase Runtime deployments are now support Oracle VM VirtualBox 5.2 as a Docker environment.

Changes in Functionality

This release includes the following changes in functionality:

Studio Displays Additional Progress View Details When Loading Workspace

When Studio opens a workspace, several system checks occur that previously could briefly show a blank EventFlow Editor canvas, depending on how many projects are being checked. Studio now displays a message at the top-left of the canvas that reads Verifying project dependencies... Clicking the message brings up the progress view to show details about the ongoing operation.

Version Information Now Checked for Java Projects

Studio now checks the version information for Java fragment projects, to make sure it matches the currently installed version of StreamBase. An Eclipse Quick Fix is offered to bring the versions up to date when necessary. (This check was formerly performed only for EventFlow and LiveView fragment projects.)

Add Container Command Integrated with Artifact Distribution Service

The epadmin add container command was integrated with ADS so that the container's operators now receive artifact notifications when the container is added via epadmin.

Default Availability Zone Now Created Upon Node Start

Prior to this release, a default availability zone was not created until a fragment was launched. Now, the availability zone is created when the node starts; a fragment launch is not required. This behavior change is expected to improve stop and restart performance on slower machines.

Manual Input View Now Shortened

Studio no longer automatically widens the Manual Input view to accommodate the longest text in the Fragment drop-down list. Prior to 10.4.1, the Manual Input view in the SB Test/Debug perspective could become too wide if its Fragment drop-down list contained long text, which could possibly push nearby buttons out of sight to the right or down.

Hover over the drop-down list to display all the text in a tooltip.

Confirm Node Stop Dialog Now Includes Do Not Show This Again Check Box

For convenience, in the Clusters view, the Confirm Node Stop Dialog now includes a Do Not Show This Again check box.

Kafka Consumer Commit Adapter Now Links Qualified Names to Kafka Consumer Adapter

By design, the Kafka Consumer adapter does not output the fully qualified adapter name with each tuple. Now, the Kafka Consumer Commit adapter can optionally take in that fully qualified name to link back to the Kafka Consumer adapter to perform the commit.

Date Format Now Changed on the WITSML Input Adapters and XML2Tuple Operator

Previously, the XML parser could not handle dates such as 2018-12-09T07:59:27.3057523Z because it used the SimpleDateFormat from Java. The WITSML Input adapters as well as the XML2Tuple operator now use a revised date format.

For example, this change replaces a string format such as 2018-12-09T07:59:27.3057523Z with one that looks like 2018-12-09T07:59:27.305+0000 before a parse is attempted.

Deprecated and Removed Features

StreamBase 10.4.1 has the following deprecations.

Cluster Publisher and Subscriber Adapter Suite Now Deprecated

The TIBCO StreamBase® Cluster Publisher and Subscriber Adapter suite is now deprecated and is expected to be removed in a future release.

StreamBase-to-StreamBase Adapter Suite No Longer Deprecated

The TIBCO StreamBase® SBD-to-SBD Input (Downstream) Adapter and the TIBCO StreamBase® SBD-to-SBD Output (Upstream) Adapter were previously announced as deprecated. As of this release, these adapters are removed from deprecation.

Certain Twitter-deprecated Functionality Now Deprecated in Twitter Adapters

User Streams, Site Streams, and Direct Message endpoints are deprecated and longer available from Twitter. As a result, when trying to use those deprecated functions in the Twitter input or output adapters, the respective Status port now generates information regarding the deprecated API. For adapter configuration, see Twitter Input Adapter and Twitter Output Adapter.

Migration and Compatibility

On macOS, Do Not Open Studio 10.4.0 After Using Studio 10.4.1

StreamBase Studio from release 10.4.1 will open your 10.4.0 workspace without requiring any conversion or upgrade. Thus, there should never be a need to return to using Studio from release 10.4.0 after installing 10.4.1.

This is not an issue on Windows, where maintenance releases replace the base major.minor release. That is, you cannot have StreamBase 10.4.0 and 10.4.1 on the same Windows machine using standard installation procedures. On macOS, however, multiple StreamBase maintenance releases can easily coexist. Therefore, it is important on the Mac to not open Studio 10.4.0 once you have installed and used 10.4.1. And never open both Studio 10.4.0 and Studio 10.4.1 at the same time.

The reason is the shared configuration directory. Starting with release 10.4.0, StreamBase Studio maintenance releases use the same configuration directory as the primary release. That is, releases 10.4.1, 10.4.2, and so on, all use the same Studio configuration directory as the one initially configured for 10.4.0. This feature allows Eclipse plug-ins that you added to Studio in the base release to still be present when you install and use a maintenance release.

The configuration directory is not the Studio workspace, but is a separate storage location for Studio metadata. See Default Installation Directories .

StreamBase Known Limitations

This section describes known limitations as of the current release of the TIBCO SteamBase® component of TIBCO® Spotfire Data Streams. Each item includes a tracking number, description, and workarounds when possible.

Known limitations for using the EventFlow debugger are described separately, in the Limitations, Tips, and Tricks section of the Using the EventFlow Debugger page.

CQS‑4679 All identical adapters and operators in an application that use the Operator getlogger() method share the same log level configuration.
Description

If you have multiple identical StreamBase or LiveView operator or adapter instances based on a given Java class in a StreamBase fragment, they all share a Logger object, and the log level of the last instance to be initialized is used.

Workaround Parameterize the log level of all the adapters of a specific class and expose that parameter through the fragment's engine.conf file.
SB‑45757 Typecheck failure: "Could not find" resource file.
Description The EventFlow Editor can get into a state where a resource file, such as a CSV file used to preload a Query Table, is not found during typechecking, resulting in a typecheck failure with no corresponding entry in the Problems view.
Workaround Re-run the EventFlow Editor's typechecker with Ctrl+T (Windows) or Cmd+T (Mac). Note that the menu command Refresh Project Typecheck Environment invoked with Ctrl+F5 (Windows) or Cmd+R (Mac) does not resolve this condition; you must run the Editor's typechecker independently.
SB‑45183 ResourceUnavailableException after stopping two nodes and restarting one node.
Description When stopping more than one node in a cluster, on restart of just one of the stopped nodes a ResourceUnavailableException error can be thrown.
Workaround Restart all the stopped nodes concurrently or reinstall the node before restarting.
SB‑45182 Default availability zone may not be created correctly when cluster stopped and started.
Description If a node in a cluster is stopped and then restarted, the default availability zone may not be created correctly.
Workaround Remove the node and reinstall before starting.
SB‑45146 Welcome launchbar shows a large red square.
Description The Welcome launchbar that appears in Studio's bottom right status bar is missing an icon, which the system replaces with a red square. On Windows, this red square can be confused with the Console view's red Terminate button.
Workaround None.
SB‑44167 iPhone connected to Mac can cause node launch failures.
Description Conditions: an iPhone is connected to a Mac with a USB-to-Lightning cable while Personal Hotspot is NOT enabled on the iPhone. Under these conditions, StreamBase Runtime nodes can fail to start.
Workaround Unplug the iPhone, or enable Personal Hotspot (whether or not you actually use Personal Hotspot).
SB‑42478 Cluster Monitor fails to start in the same cluster as monitored.
Description Attempting to start the Cluster Monitor in the same cluster as other applications can fail.
Workaround Run the Cluster Monitor feature in a separate cluster from the one containing the applications being monitored.
SB‑42410 Duplicate engine log files.
Description Duplicate engine log files exist in both the node directory's top level and in its logs subdirectory. The other user visible log files are now all located in the logs subdirectory.
Workaround None. The engine log files in the node directory's top level can be ignored. The same information is available in the engine log files found in the logs subdirectory. The duplicate log files are expected to be removed in a future release.
SB‑42324, SB‑30773, SB‑30846 Inconsistent containerName behavior.
Description If you define a StreamBase container name with the containerName parameter of the sbengine HOCON configuration type, the runtime behavior is different for fragments run in Studio compared to epadmin launches. Studio places the EventFlow module in a container named default, following standards set in StreamBase 7.x, whereas epadmin honors the configuration-set container name.
Workaround None.
SB‑42093 Reloading the entire node configuration when attempting to configure the cluster monitor fails.
Description Attempting to reload a cluster monitor configuration embedded in a node deploy configuration file using the epadmin load configuration command quietly does nothing.
Workaround Create a separate configuration file with just the cluster monitor configuration and load and activate that configuration.
SB‑41896 Studio Support Wizard screen capture can fail on Mac.
Description The StreamBase Support Wizard screenshot feature preview may not display properly under certain multi-monitor and/or Retina display hardware conditions.
Workaround Use the Support Wizard to guide you to continue; the Support zip file will still contain the screenshot that you can verify in the archive prior to sending to TIBCO. For more information on the Support Wizard, see StreamBase Support Wizard for Troubleshooting.
SB‑41099 Calling Help via management API throws null pointer exception
Description Executing help commands using the DtmCommand.execute method in the management API fails with an exception.
Workaround None. This issue is expected to be resolved in a future release.
SB‑35326 Shutting down at debugger breakpoint causes engine to fail with an error.
Description Stopping a JVM with a breakpoint set in the debugger can cause the JVM to exit with an error that requires the node to be removed and reinstalled.
Workaround Ensure that no breakpoints are set in a debugger when shutting down a JVM.
SB‑32239 Bogus FATAL Invalid response trace seen when stopping a node.
Description When deploying fragments, a misleading fatal error message may be returned when terminating the fragment or the node on which it is deployed. For example:
MESSAGE: dtm : FATAL(RQ:A.dstest): Invalid response: <ready/>
Workaround This message can be safely ignored.
SB‑30948 Trouble using the TERR operators on macOS.
Description On macOS, EventFlow modules that use the TERR operators with TERR versions before 4.4 fail to start even when using the Use Embedded TERR check box. This includes the TERR operator samples shipped with StreamBase.
Workaround If you can, update to TERR 4.4 or later, which is included with StreamBase 10.2.1 and later. If you must use a TERR version before 4.4, there are extra configuration steps on macOS, compared to Windows and Linux. These steps are detailed in the Operating System Configuration for TERR sections of the pages that describe the TERR Operator and the TERR Predict Operator.
SB‑30898 On Windows only, virtual network adapters slow fragment startup with StreamBase before 10.3.0.
Description If you have Oracle VM VirtualBox® or Microsoft Hyper-V installed, and one or more of your virtual machines has its virtual network adapter activated, this slows down the launch of EventFlow and LiveView fragments into a StreamBase Runtime node by several minutes.
Workaround Upgrade to StreamBase 10.3.0 or later, where this issue is corrected. If you must use an earlier release, temporarily disable the network adapter feature of your VirtualBox VMs as described in Windows and Virtual Network Interfaces.
SB‑30270 Failure to start Studio or Manager by double-clicking on macOS Sierra or High Sierra
Description MacOS releases 10.12 Sierra and 10.13 High Sierra have a security model that is stricter than previous releases. As part of their security, these releases automatically block unsigned, downloaded application bundles with .app extension from being able to run. Unfortunately, this affects the application bundles for StreamBase Studio 10.x and StreamBase Manager 10.x.
Workaround See the list of suggested workarounds in Starting StreamBase Studio on macOS Sierra.
SB‑29050 Error when debug stepping into or stepping over a Decision Table operator.
Description When using EventFlow debugging, stepping into or over a Decision Table operator is not supported.
Workaround Set your breakpoints upstream or downstream. Also, consider using the features of the Decision Table Analyzer to get a debug-like view of how the operator responds to different input tuples.
SB‑28856 Deleting decision table rows does not re-number rule IDs.
Description When using the Decision Table editor to delete and then add a new decision table rule, the rule ID does not renumber. For example, by deleting row 5 and adding a new row, the rule ID numbering is now 1...4, 6.
Workaround None.
SB‑28669 Error message: Grows beyond 64KB.
Description In rare cases, compiling small StreamBase applications can produce an error message containing the words Grows beyond 64KB.
Workaround Contact TIBCO StreamBase Technical Support for a workaround for this issue.
SB‑28598 Multi-container StreamBase applications cannot use the same ActiveSpaces metaspace.
Description StreamBase applications deployed with multiple containers receive metaspace already exists errors when attempting to connect to the same TIBCO ActiveSpaces metaspace from different containers.
Workaround None.
SB‑28452 Delta stream arc limitations in the EventFlow Debugger.
Description If a delta stream arc is a direct connection between a Query Table and an Output Stream, and if that arc has a Debugger breakpoint, the breakpoint is not hit at during debugging with the EventFlow Debugger. Similarly, while debugging, stepping over to try to reach that arc does not suspend on that arc.
Workaround Insert a no-op Map operator between the Query Table and the Output Stream. Then a breakpoint on the arc between the Query Table and the Map does work, and stepping over reaches that arc as well.
SB‑26629 RPM installation method issues on RHEL 7
Description StreamBase and LiveView are supported on Red Hat Enterprise Linux version 7.x. The archive installer is the recommended installation method. If you use the RPM installation method, RHEL 7 issues several warning messages during installation that complain about file removal failures, and issues an overall warning that RHEL 7 "may not be compatible with this version of StreamBase."

Despite these warnings, the installation does succeed. The only consequence is that rpm -e fails as an uninstallation method.

Workaround Remove StreamBase directories manually to uninstall an RPM installation on RHEL 7. Otherwise, all StreamBase and LiveView processes run as expected on RHEL 7.
SB‑26927 Error message NamedSchema is not a function that can be called.
Description In compiling the updating expression for a dynamic variable where the expression references a named schema, if a field in the tuple presented by the updating stream also has the same name as the named schema used in the expression, the field is instead evaluated as a function. This raises the error NamedSchema is not a function that can be called. This compilation behavior and language ambiguity was introduced along with the function data type.
Workaround The required migration step is to rename either the field or the named schema to eliminate the ambiguity.
SB‑26237 Constant definitions used as component properties are not used at runtime.
Description StreamBase Studio properly typechecks defined constants when used in operator properties, but at runtime substitutes their names instead of their values.
Workaround Do not use defined constants when specifying operator properties.
SB‑26017 Asynchronous timeouts for Gather operators in parallel applications can be inaccurate
Description High availability applications that include Gather operators may incorrectly compute timeout intervals because the operator relies on now() instead of calling out to the parallel scheduling service.
Workaround None
SB‑22297 Commented-out error input streams consume error tuples.
Description An error input stream, despite being disabled with the EventFlow comment-out feature, still catches errors thrown, but consumes any incoming errors and fails to pass them on.
Workaround To temporarily disable error streams, copy them to a placeholder module and remove them from the active module.
SB‑21843 In the TableAccessor API, ClassCastException is thrown if not using a Tuple from TableAccessor#createRow.
Description If methods in the com.streambase.sb.operator.TableAccessor interface that accept a Tuple are not provided a Tuple retrieved from TableAccessor#createRow, a ClassCastException may be thrown by the API.
Workaround Always use TableAccessor#createRow when using TableAccessor API methods.
SB‑20449 Display issues with years before 2 AD.
Description The timestamp data type can hold timestamp values in the range -(2^62) to (2^62)-1, and can successfully display any future date in the next 146 million years and any past date to around year 2 AD. However, the year value for dates earlier than 2 AD may not display correctly.
Workaround None.
SB‑18294 Union operator: sub-field order of tuple fields must match with strict options.
Description When using the Union operator with its Strict union or Declared schema options, the order of sub-fields of tuple fields must match exactly. This is in contrast with the default Loose union option, where strict sub-field ordering is no longer required.
Workaround None.
SB‑16594 Extract as Module feature copies items instead of importing them.
Description The Extract as Module feature makes a copy of the source module's definitions and named schemas, and places the copies in the newly created module. Best practice would be to import those features from the source module to the new module, and to copy all imports from the source to new modules.
Workaround After using Extract as Module, manually convert the copied definitions and named schemas to imports.
SB‑14133 On Linux, sb-config --cxx returns a setting for G++ newer than 4.5.
Description On Linux, in StreamBase samples that build C++ code, some of the example Makefiles show sb-config --cxx as the correct usage to determine the G++ compiler to use. On newer Linux distributions, this command returns the distribution's default G++ compiler, which may not be supported for building StreamBase client code, and sb-config does not honor the CC and CXX environment variables.
Workaround On such systems, install GCC and G++ 4.5, and edit the Makefiles to specify CXX=g++-4.5.
SB‑13398 Filter operators with very large predicate settings may result in a runtime EvalException error.
Description Filter operators with several output ports and complex expressions to evaluate for each port may result in a com.streambase.sb.runtime.exceptions.EvalException error when attempting to run the application that contains such a filter.
Workaround Add another Filter operator and split the predicate settings between the two Filter operators.
SB‑13113 Application output view does not display UTF-8 characters.
Description Both StreamBase Server and StreamBase Studio are fully capable of processing and displaying Unicode character sets, but neither is set to do so by default.
Workaround Follow the instructions in Unicode Support to configure StreamBase Server, Studio, and any StreamBase client applications to process the UTF-8 character set.
SB‑10792 The Query operator converts a JDBC data type differently when using explicit schemas than when using database data types.
Description When explicit schemas are used, the Query operator does not use database metadata to determine the mapping between JDBC data types and StreamBase data types. The JDBC data type Types.TIME is normally converted to an interval timestamp since it has a time, but no date component. But when explicit schemas are used, there is no database type information, so Types.TIME is converted to an absolute timestamp.
Workaround None.
SB‑10486 Hierarchical data restrictions.
Description Patterns by value do not support using the tuple data type for their on-value portion. Similarly, tuple subfields cannot be used as the index or primary key of a Query Table.
Workaround Design schemas so that the intended sort field or key is a top-level numeric or timestamp field, as described in StreamBase Pattern Matching Language.
SB‑10363 No StreamBase data type corresponding to Sybase timestamp.
Description When used with Sybase data sources, both EvenfFlow and StreamSQL fail to convert timestamps, resulting in typecheck errors. This is because the Sybase timestamp is based on the Sybase varbinary data type.
Workaround In EventFlow or StreamSQL code that will be used for Sybase data sources, use the Sybase datetime data type instead of timestamp.
SB‑6862 Not all databases have native blob support.
Description For example, Microsoft SQL Server and Sybase do not have blob support. For these databases, you can write blobs into varbinary and possibly other types. But when blobs are read from a select statement, they are returned as strings, not blobs.
Workaround Add a Map operator and convert the string to a blob.
SB‑5882 Tuple dimensions do not reset counter when another dimension closes a window early.
Description A tuple-based dimension that closes due to other dimensions (for example, after another dimension times out) does not reset its counter. When this happens, the next window will close based on the total number of tuples received, resulting in a partially full dimension.
Workaround None.
SB‑4559 Join timeout is not asynchronous.
Description Join timeout in the Join operator is not asynchronous. That is, the Join operator does not remove a tuple from its buffer until the timeout has passed and another tuple arrives on the same input stream. Tuples received on one input stream do not affect the buffer of the other input stream.
Workaround None.

StreamBase Resolved Issues

This section provides a list of errors corrected in release 10.4.1 of the TIBCO StreamBase® component of TIBCO® Spotfire Data Streams.

Fixed in 10.4.1
Number Resolution
TIBCO StreamBase® 10.4.1 incorporates all fixes resolved in the release 10.0 series through 10.4.0 and all fixes resolved in the release 7.7 series through 7.7.5.
SB‑45617 Setting a status code on the Web Server Response adapter via the Status Code Field Name property now properly disconnects a websocket with that status code. Setting a null status code keeps the websocket active.
SB‑45616 The Web Server Response adapter could consume 100% of the available CPU at idle in some circumstances. This was fixed.
SB‑45592 There was a problem where, after starting a StreamBase application launch in Studio, if that launch was terminated relatively early, an entry could appear in the Error Log view complaining of an Unexpected exception, involving a NullPointerException with a stack trace whose top element mentions stopTransferringOutputToConsolePage. This problem was resolved.
SB‑45563 The MQTT Client Subscribe adapter would filter out inbound topics when matching against a wildcard. This was fixed.
SB‑45554 While using the EventFlow debugger, the Debug view may have incorrectly shown lines that started with (not in workspace!) followed by an absolute path to an EventFlow module file. This situation could happen when debugging a source from a project that did not exist in Studio's workspace file system tree. That problem was fixed.
SB‑45498 Any File Writer adapter could NPE if data was written before a file was opened. This was fixed.
SB‑45492 Configured node types were incorrectly treating fragment dependencies as top-level fragments in some cases, which incorrectly caused engines to be created for the dependent fragments. This was corrected.
SB‑45490 In some scenarios, Studio would prompt to save a file twice. For example, if you modified an EventFlow fragment and ran it without saving first, a dialog may prompt to Auto-Save unsaved changes. Declining to save may prompt again to save changes. This was fixed.
SB‑45473, SB‑45251 When hitting an EventFlow breakpoint during debugging, the current thread in Debug view is often not selected. To address this, Studio now adds two buttons to the Debug view toolbar. One is an up-arrow, the other is a down-arrow, and each has a small pause double-bar icon over it. You can use them to automatically find the next or previous suspended thread in the Debug view, and automatically select the top stack frame of that suspended thread.
SB‑45423 Direct output from a Python process is now propagated to the logging framework. Previously, the stdout and stderr streams from the Python process were redirected to the low-level streams of the JVM process running the StreamBase server. It was difficult to find the warning and debug statements that originated from the Python code. With this change, the output is processed as any other output from platform components using the common framework.
SB‑45395 This release fixes an issue in which the automated conversion of JMS adapter configurations, to HOCON format, added duplicate quotation marks to server and/or destination names, under certain conditions.
SB‑45362 The WITS adapters were updated to address potential socket communication failures. The adapters now use PureJavaComm version 1.0.2; new reconnection logic was also added.
SB‑45322 Running the epadmin display engine command could fail if your configuration's trusted host authentication was disabled. This was fixed.
SB‑45321 In Studio, the Refactor>Rename option would fail when renaming input streams. The Refactor option was updated to now use StreamBase 10's fully qualified name convention.
SB‑45316 Schema typechecking was improved to catch an invalid null value being used to initialize a list.
SB‑45303 The WITSML Log Data Convert adapter would incorrectly assume the logCurveInfo contains an index field. If that field was not present but the mnemonicList field was present instead, the index would become out of order. The adapter now checks for the mnemonicList field in the logData field, and uses that as the column index for the logCurveInfo.
SB‑45280 An issue prevented WITSML write operators from filtering out empty values. This was fixed.
SB‑45264, SB‑45265, SB‑45266 The epadmin display engine and display services commands inconsistently displayed EventFlow service records for (a) URI information when engines were stopped, (b) applications that were deployed with the autostart=false option or (c) whether engines were stopped and started when random ports were specified. These related issues were fixed. For (c), the service records are now removed whenever an EventFlow or LiveFlow fragment is stopped.
SB‑45255 The epadmin display artifact command previously displayed the wrong artifact file path. The command now displays the path of the artifact file on the node executing the command. Previously, it displayed the path of the file on the artifact's active node. If the artifact file does not exist on the node executing the command then Not Cached on node name is displayed.
SB‑45253 It was possible for an epadmin browse services process to be left running after Studio exits. One use case was: open Studio and close the Clusters view in all perspectives and restart Studio. Then upon exiting Studio, such an orphaned epadmin process would be left behind. This was fixed.
SB‑45242 Removing the VM arguments from an EventFlow fragment launch had no effect on subsequent re-launches, until Studio was restarted. Changing the arguments such that some VM argument text remained DID work, however. This was fixed.
SB‑45241 The Diameter adapter was fixed so it now correctly checks AVP data lengths.
SB‑45240 This release fixes an issue in the Decision Table's Table Analyzer view that prevented the Analyze operation from functioning properly.
SB‑45234 This release fixes an issue with the presentation of some adapter settings in the StreamBase Properties view. For affected adapters, raw field names are displayed, with no customized support (descriptive names, tool tips, and so on). This issue affected the Feed Simulation and Microsoft .NET adapters, as well as LiveView Alert configuration.
SB‑45110 Changing the default distribution listener addresses using the distributionListenerInterfaces property in a node deploy configuration could cause the partitions in the default availability zone to fail over. This was fixed.
SB‑43774 This release fixes an issue that affected editing Query Table schemas — with the Definitions tab open, Studio correctly grayed-out the Query Table's partitioning options yet incorrectly kept them active. This was fixed.
SB‑30850 Studio's adapter selection dialog could hang in cases where the selected adapter required Maven downloads. This was fixed.
