StreamBase 10.6.0 Release Notes

These were the release notes for the TIBCO StreamBase® component of TIBCO® Streaming 10.6.0.

New Features

TIBCO® Streaming 10.6.0 adds the following updates and new features:

New Platform Support

TIBCO® Streaming Now Requires Java 11

Starting with release 10.6.0, TIBCO Streaming 10.6 runs only with and requires an installation of Oracle JDK 11.0.7 or a later JDK 11 version.

On all supported operating systems, the TIBCO Streaming installation kit provides the runtime components of Oracle JDK version 11.0.7 in a subdirectory of the StreamBase installation directory, for private use to run StreamBase program fragments and applications from within StreamBase Studio. As before, StreamBase detects and prefers a system-installed JDK, and uses the bundled JDK as a fallback. See further details about the JDK requirements of this release in the JDK entry of the Supported Configuratons page.

New Support for Kubernetes and Helm

The StreamBase Runtime has had long-standing support for its own node-based discovery service that uses communication over UDP ports as its hallmark.

To better integrate TIBCO Streaming applications in Cloud environments, where UDP broadcasts and firewall management is restricted, release 10.6.0 introduces support for industry-standard Kubernetes as an alternative discovery service and Docker container deployment manager. This release also adds support for Helm as a package manager for Kubernetes configurations.

This release of Studio builds on its Maven-based automation for generating Studio projects that are ready to build and load into a Docker environment. The File>New>StreamBase Project wizard now has checkboxes that extend its Docker support with two new options:

Select the Kubernetes checkbox to have Kubernetes support files generated into the project folder for the new project. Select the Helm checkbox to generate the additional Helm support files.

You can run and test your Docker containers with Kubernetes management on your development workstation by installing Docker Desktop for Mac or Windows. Docker Desktop is required for Studio's Docker integration; install the latest version available. See the Cloud section of the StreamBase Administration Guide for instructions on building a containerized StreamBase Application in StreamBase Studio.

Note

When you obtain third-party software or services, it is your responsibility to ensure you understand the license terms associated with such third-party software or services and comply with such terms.

Studio Now Built on Eclipse 4.15

StreamBase Studio and StreamBase Manager are now based on Eclipse 4.15.

As with every major release, TIBCO strongly recommends using File>Import to import your projects from previous releases into a new, unused Studio 10.6 workspace. Be sure to use the Copy projects into workspace option.

StreamBase Studio silently updates the workspace format of older projects. Once imported and updated to 10.6 format, do not reopen a 10.6 project with an earlier release of Studio.

Visual Studio 2019 Now Supported For Building StreamBase Clients

TIBCO Streaming 10.6.0 introduces support for Microsoft Visual Studio 2019, which TIBCO recommends for building C++ or .NET clients for Windows.

Other Visual Studio support changes are described in Deprecated and Removed Features below.

Bundled Maven Version Now 3.6.3

Release 10.6.0 includes a standalone installation of Maven 3.6.3 for customer command-line use as described in the Maven entry of the Supported Configurations page.

CentOS 8 Now Supported

StreamBase now supports CentOS 8 as a staging and deployment server platform.

New Studio Usability Enhancements

Studio Now Supports Eclipse Dark Themes

As part of 10.6.0's adoption of Eclipse 4.15, Studio now supports Eclipse Dark themes. To configure a Dark theme, see Changing Studio's Appearance. All Studio perspectives, views, and editors are affected by the theme change, with the exception of the Palette view.

New LiveView Perspective Introduced

Studio now includes a LiveView perspective that opens automatically when you run a LiveView fragment in Studio. The perspective has many features of the TIBCO LiveView Desktop™ utility, but now integrated with Studio. This provides developers with an automatic and convenient way to view the tables of one or more running LiveView fragments, and to perform queries against them.

Operators and Adapters Drawer Now Searchable

The Palette view now includes a search field in its title bar where you can narrow the display in the view by specifying a few letters of the name of an operator, stream, or data construct of interest. This works best when you pin open all three drawers of the view, to see the effects of the search in all drawers at once.

Kafka Enhancements for the Connectivity Wizard

The Apache Kafka option for Studio's LiveView Connectivity Wizard now supports creating Kafka projects with basic and advanced authentication options. Click the Generate Security Settings link at the bottom of the Advanced Options grid to open the following dialog. You can select Basic-only by clearing the Use SSL Encryption check box, or select the combination of Authentication and Encryption settings appropriate for your Kafka cluster.

TCM Enhancements for the Connectivity Wizard

The TIBCO Cloud Messaging option for Studio's LiveView Connectivity Wizard was enhanced with UI support for constructing a text matcher string in the Content Matcher field. The dialog now has an Assist Me link next to the Content Matcher field. When selected, a dialog appears showing messages seen on the TCM channel, as well as a chooser for selecting fields of interest.

In previous releases without the assisting dialog, you had to type a raw content matcher string into the Content Matcher text field, such as {"topic":"sales","department":"widgets"}.

Specifying Configuration Load Order When Launching Fragments Now Supported

You can specify a prerequisite for a HOCON configuration file in a Run Configuration dialog for EventFlow or LiveView fragments. This feature lets you specify one configuration file (say, B) as a prerequisite for another, A. In this case, when Studio runs the fragment, it loads B before A, independent of other load order considerations. See Configuration Settings for more information.

For every rule that you define, Studio loads the prerequisite HOCON file before the file of interest. The ordering of the remaining HOCON files remains as described in HOCON Configuration Load Order. If you define an illogical set of rules, then all rules are ignored.

Docker Containers Now Support Cluster Monitor

Docker containers can now include the Cluster Monitor application. See this page for configuration details.

Markdown Viewer Integrated with Studio

StreamBase Studio now includes a Markdown viewer much like the one on GitHub, which provides an HTML-like view of Markdown format files in general, including those pulled into Studio as part of the community samples and online versions of supported samples.

The viewer supports Markdown format cross-reference links to tags in the same document, but links to a separate document opens it in text editor view.

Studio Typechecking Improved

When typechecking EventFlow modules, Studio now looks for container-scoped variable definitions in EventFlowDeployment and/or ParameterSettingsGroup configuration files.

Run Configuration Tooltips Now More Comprehensive

Tooltips in the Run and Debug Configuration dialogs were updated to provide more comprehensive messages for port selections.

StreamBase Runtime Enhancements

Web Service for Engine Metrics Now Supported

The REST API introduced in 10.5.0 now includes engine metrics. Enhancements include:

  • The StreamBase Java Client API was updated to support adding, removing, updating, and querying the web service.

  • The metrics web service for retrieving node and engine metrics data.

  • New epadmin metric command target.

  • Support for automatic installation of WAR files into the node's web server by adding a dependency in the POM file for EventFlow, LiveView, and Java engines.

Web Services Security Enhanced

Security for web services was enhanced to support:

  • Disabling authentication per web service.

  • Enabling Open ID Connect Authentication realms.

  • Token-based authentication for when epadmin commands are executed from the context of the admin web service. Now, users do not need to run commands from a machine in the Trusted Hosts list when querying the admin web service.

Configuration Enhancements

New PrivilegeSettingsGroup Security Root Object Added

A new root object com.tibco.ep.dtm.configuration.security.PrivilegeSettingsGroup allows a security role to include any number of named privilege settings. Privilege settings can include other settings, allowing greater flexibility and reuse.

pageSize Property Value Limit Now Increased

The pageSize property for Client Listener configuration increased to a maximum of 16384 bytes.

New Local Authentication Realm Properties Added

The local authentication realm now includes the following properties:

  • failedLoginLockoutDurationMinutes, which allows you to set the number of minutes a user's account remains locked for exceeding the lockout threshold.

  • failedLoginLockoutThreshold, which allows you to set the number of consecutive failed login attempts required before the user's account is locked.

See Number of Login Attempts for a discussion of using this feature in a non-default Local Authentication Realm.

Artifact Distribution Service Now Improved

Release 10.6.0 includes the following enhancements to the Artifact Distribution Service:

The Artifact Distribution Service (ADS) was updated so that the name of the artifact service record no longer exceeds the maximum service name length of 255 characters.

ADS now updates the Last Model Request Time property in the node service record to signal to the (separately installed) Artifact Management Server (AMS) that artifacts are required. Further, the artifact service record was deprecated as the means to signal AMS, but, ADS still publishes the artifact service record for compatibility with previous AMS versions.

ADS configuration now fails activation if another active ADS configuration on the node defines the same artifact but with different data. Previously, the configuration activation succeeded and an INFO message was raised at fragment start time. At fragment startup, it is still possible to get the artifact already loaded with different data error if a different node in the cluster has defined the artifact with different data. In this case a WARN message is raised.

ADS now logs a message if fragment startup fails because required at startup artifacts were not received within the artifact-wait timeout period and the Artifact Management Server did not contact the node to get the list of artifacts that the fragment requested. This message is in addition to the existing message that specifies that the fragment failed because artifacts were not received (which can apply to several use-cases).

New epadmin Features

New EP Command Reference

The TIBCO Streaming EP Command Reference now provides a detailed page for every epadmin target, with each of that target's commands explained, along with its command parameters.

web Target Has a New Option

The epadmin display web type=webservice command now includes the --detailed parameter to display additional web service information such as any failed requests, to identify possible denial-of-service attacks on endpoints.

metric Target Now Active and Renamed

The epadmin command target, metric, which was introduced in 10.5.0 for future use, can now be used to display metrics such as CPU utilization for nodes running EventFlow and LiveView applications. Note also that the target name changed in 10.6.0 from metrics to metric.

Engine Start and Stop Commands Now Updated

The start engine command no longer waits for the engine to be fully started before returning. Also, the stop engine command now does not return until the engine has stopped.

New Authentication Commands Added

The epadmin display authentication and update authentication commands were added to retrieve and update the local authentication realms for a running node, respectively.

Create Snapshot Command Now Writes Locally

The epadmin create snapshot command now creates the snapshot archive on the local file system. By default, the snapshot archive is placed in the current working directory of the epadmin command, or you can specify an alternate location with the destination parameter, using an absolute path or one relative to the current directory.

In previous releases, the command created the snapshot archive in a directory named snapshots/nodename, parallel to the node directory, and you could use the destination parameter to specify a directory relative to that location.

New and Enhanced Adapters

SMPP Adapter Introduced

This release includes the TIBCO StreamBase® Short Message Peer-to-Peer Protocol (SMPP) Adapter. The adapter enables sending and receiving of short text messages (SMS) over the Internet. See the sample page to learn how to demonstrate the adapter's features.

Slack Adapters Suite Introduced

This release includes a trio of adapters to support connectivity to and from the Slack Technologies messaging platform:

See the sample page to learn how to demonstrate the adapter's features.

ETP Adapter Suite Introduced

The TIBCO StreamBase® Adapter for ETP allows StreamBase to interact with data from an ETP (Energistics Transfer Protocol) v1.1 server. The adapters in this set include:

  • The ETP Control adapter, which is used to control the connection with the ETP server (connection, disconnection, server status, and so on).

  • The ETP Store Get adapter, which is used to retrieve values from ETP nodes.

  • The ETP Discovery adapter, which is used to traverse the ETP server's node hierarchy and retrieve metadata for these nodes.

  • The ETP Streaming adapter, which is used to subscribe to value nodes and get continuous updates when the nodes' values change, as well as perform range requests for such values.

See the sample page to learn how to demonstrate the adapter's features.

HTTP Client Adapter Introduced, Replacing Web Reader

The new TIBCO StreamBase® HTTP Client adapter performs HTTP requests and emits the contents via a Data output port. This adapter replaces the Web Reader Input adapter, which is now deprecated.

Diameter Adapters Enhanced

The Diameter adapters include the following enhancements:

  • Diameter Client and Server Input adapters now support SSL connections. See the Diameter Client Input and Server Input Adapter documentation for details.

  • The Server Input Adapter can now specify port 0 to select a random port.

  • The Client Input Adapter now supports automatic reconnection.

Rendezvous Adapters Enhanced

The TIBCO StreamBase Rendezvous output adapter can now convert underscore (_) numeric field names to pure numeric field names in TIBCO Rendezvous and back again on the subscribe side.

The TIBCO StreamBase Rendezvous input and output adapters now unsubscribe and disconnect from the Rendezvous message bus when they suspend, and reconnect when they resume. Current subscriptions are saved for when resume is called. More specifically, both adapters now support multiple options to connect at startup, auto-reconnect, reconnect wait, and also a control port to connect and disconnect manually.

Previously when suspended, the input adapter:

  • maintained all subscriptions

  • continued to receive Tibrv messages

  • stopped emitting tuples on its output ports.

OSIsoft PI Adapters Adapters Now Offer New Authentication Option

A new option was added for OSIsoft PI adapters built on the PI SDK to specify the authentication type to perform — currently either Windows Authentication or PI Authentication.

JMS/EMS Operators Now Support Integer and Solace's SOL_CLIENT_ACKNOWLEDGE Acknowledgment Mode

Release 10.6.0 now supports Solace JMS's SOL_CLIENT_ACKNOWLEDGE as a value to the JMS/EMS operators' acknowledge-mode configuration setting.

The operators also now accept an integer value for this setting. For example, SOL_CLIENT_ACKNOWLEDGE is defined as 4 in the Solace JMS API; you can now use either the constant name or its integer value interchangeably.

Miscellaneous Enhancements

Engine Affinity Configuration Now Audited

The StreamBase Runtime audit process now rejects a configuration activation/replacement if an engine affinity configuration does not have explicit or implicit affinity with at least one engine.

Cluster Monitor Application Now Includes Top-level HOCON File

As a configuration copy-and-paste convenience, the default node deploy configuration for the supplied Cluster Monitor application is now shipped (next to the Cluster Monitor application zip file) in distrib/tibco/sb/applications/cluster-monitor-node.conf. The file was also renamed from node.conf to cluster-monitor-node.conf.

Documentation Enhancements

The TIBCO Streaming documentation has the following improvements and new additions for release 10.6.0.

StreamBase Runtime Guides Now Integrated

In previous releases, four Guides that help you understand and configure the StreamBase Runtime were only available offsite in an older format. Starting with release 10.6.0, these four Guides are now integrated into the TIBCO Streaming documentation:

New EP Command Reference

In addition to the four Guides described above, an all new TIBCO Streaming EP Command Reference was carved out of an appendix in the former Runtime Administration Guide, then significantly enhanced and extended to become a top-level book of its own.

Security Model Pages Updated

The Default Security Configuration and Trusted Hosts pages were extended and clarified. The Local Authentication Realm page was clarified throughout with a new Account Lock Features section added.

TERR Support Updated

Instructions for installing and using an alternate TERR installation were re-tested and re-wrtitten.

New Page: Finding the adminport for a Node

The Concepts Guide has a new page, Finding the adminport for a Node.

Using Docker Section Updated and Extended

The Cloud section of the StreamBase Administration Guide was modernized, corrected, and extended to include this release's Kubernetes support.

Changes in Functionality

This release includes the following changes in functionality:

Changes in EventFlow Engine Listener Port Selection

Starting with TIBCO Streaming 10.6.0, the TCP port for the Client API listener for EventFlow engines is now determined at engine startup to be a random port not already in use. This is true for all EventFlow fragment launches from Studio or from the command line, in the absence of a configuration file that sets an exact port number. This change was made to have Studio's behavior better match the command-line deployment experience, and to better support Cloud and Docker deployments, where fixed port numbers can be problematic.

In previous releases, Studio launches of EventFlow fragments set the port at the legacy default value, 10000. If that port was in use, a random, unused port was selected. Command line launches have always set the listening port to a random, unused value.

See the portNumber property in the StreamBase Client API Listener page in the Configuration Guide for further details.

Changes in LiveView Engine Listener Port Selection

Starting with TIBCO Streaming 10.6.0, the determination of the TCP port for the Client API listener for LiveView engines has new behavior in StreamBase Studio. Now, the first LiveView fragment to start gets port 10080 if available, the second gets 10081 if available, the third 10082, and so on. The EventFlow engine that accompanies every LiveView launch now gets a random listener port, as described above.

Tip

Remember that you cannot run the same project two or more times in the same Studio session unless you configure the project to use the JDBC or Transactional Memory metadata store type.

In previous releases, Studio launches of LiveView fragments set the port at the legacy default value, 10080, while the accompanying EventFlow server took 10000. These port settings were set the same for all Studio launches of LiveView fragments, which required you to use configuration files to manage the ports for more than one LiveView fragment at a time. Command line launches have always set the listening ports to a random, unused value for both LiveView and EventFlow.

Note

If you have LiveView projects with existing configuration files that set the LiveView and/or accompanying EventFlow listener ports, consider whether you need to continue that practice with 10.6.0 and later releases of TIBCO Streaming.

See the portNumber property in the LiveView Client API Listener page in the Configuration Guide for further details.

epadmin web Target Now Works When Node is Stopped

In previous releases, you could not run any epadmin web command for a node in its Stopped state (including a node that is installed but not started). Now, you can run epadmin web commands once the node is installed, whether or not the node is in a Stopped state.

epadmin display node Output Updated

The output of the epadmin display node command was changed for the Discovery Service lines to reflect the support for Kubernetes when enabled. For the default UDP discovery service compatible with previous releases:

Discovery Service Implementation = UDP
Discovery Service Port = 54321
Discovery Service State = Running

Starting with this release, if you have configured to use the Kubernetes discovery service:

Discovery Service Implementation = Kubernetes
Discovery Service Port = Not applicable
Discovery Service State = Running

In addition, the Discovery Service state line was removed from the install node and start node output (because the discovery service is always running).

LDAP Client Connection Adapter: Disconnect Command Behavior Now Changed

Sending a Disconnect command through the LDAP Client Connection adapter's control input port, when the adapter is not connected to an LDAP server, now emits a Disconnected status tuple, with –1 for the port. The previous behavior was to do nothing when the Disconnect command was sent.

Separately, all output (connect and disconnect) status messages now contain the original input tuple.

JMS Request/Reply Operator Properties Now Removed, Behavior Changed

The JMS Request/Reply operator no longer contains the following properties:

  • Configured Destination Name For Replies. Now, the destination is always a temporary queue.

  • Number Of Concurrent Processing Threads. Now, to have multiple concurrent requests outstanding, configure multiple JMS Request/Reply operator instances.

  • Max # Of Messages In Flight. Now, every thread blocks until a reply is received to the current request, or the timeout expires.

Deprecated and Removed Features

The following features are deprecated as of StreamBase 10.6.0.

Java 8 No Longer Supported

Starting with TIBCO Streaming 10.6.0, Oracle JDK 8 is no longer supported for deploying and running EventFlow or LiveView fragments, or StreamBase applications. TIBCO Streaming 10.6 now requires Oracle JDK 11.0.7 or a later JDK 11 release, as described in the New Features section of these release notes, and on the Supported Configurations page's JDK entry.

Visual Studio Supported Version Changes

Microsoft Visual Studio 2010 is no longer supported for StreamBase client creation on Windows. Release 10.6.0 also deprecates Microsoft Visual Studio 2012.

TIBCO Streaming 10.6.0 introduces support for Microsoft Visual Studio 2019, which TIBCO recommends for building C++ or .NET clients for Windows.

Web Reader Input Adapter Now Deprecated

The Web Reader Input adapter is now deprecated. Instead, use its replacement, the TIBCO StreamBase® HTTP Client adapter.

Four IP Packet Stream Adapters Now Deprecated

Four TIBCO StreamBase® adapters for IP packet streams that rely on the WinPcap library and have been provided for Windows only are now deprecated as of release 10.6.0, and are likely to be removed in a future release. The four are the IRC Reader, HTTP Reader, POP3 Reader, and SMTP Reader adapters. Their samples were removed from this release.

HOCON RoleToPrivilegeMappings.privileges Property Now Deprecated

The following security configuration property is now deprecated:

com.tibco.ep.dtm.configuration.security.RoleToPrivilegeMappings.privileges

Instead, use:

com.tibco.ep.dtm.configuration.security.RoleToPrivilegeMappings.roles
HOCON Service Discovery Properties Now Deprecated

The following Service Discovery Adapter HOCON properties are now deprecated:

  • com.tibco.ep.streambase.configuration.servicediscoveryadapter.ServiceDiscovery.discoveryPort

  • com.tibco.ep.streambase.configuration.servicediscoveryadapter.ServiceDiscovery.discoveryHosts

HOCON StreamBase Engine Properties No Longer Supported

The following StreamBase engine properties were deprecated in 10.3.0 but were unannounced:

  • StreamBaseEngine.streamBase.containerConnections

  • StreamBaseEngine.streamBase.modules

The deprecated properties were replaced with the following:

  • EventFlowDeployment.containerConnections

  • EventFlowDeployment.containers

Support for the deprecated properties was removed in 10.5.0 and retroactively announced in 10.6.0.

The following features were removed from StreamBase 10.6.0.

Python Client API Support Removed for Windows

Because the Python community is winding down its support for Python 2.7, TIBCO Streaming could no longer build its Python Client API libraries for Windows. Accordingly, the TIBCO Streaming Python Client API is now supported only on Linux, and only for Python 2.7.

This does NOT affect the Python operator or Python Instance operator, which both have a wide variety of Python version support on macOS, Windows, and Linux, in both the 2.7 and 3.x Python families.

Legacy jsbclientgen Command Removed

The jsbclientgen command outlived its usefulness and was never updated to work correctly in the StreamBase 10 era. Accordingly, this command is now removed as of release 10.6.0. To generate a simple dequeuer or enqueuer Java client, use StreamBase Studio's File>New>StreamBase Client wizard.

Legacy sbmonitor Command Removed

The StreamBase 7.6.5 release announced the deprecation of the sbmonitor command. This command is now removed as of release 10.6.0. The StreamBase Manager application and the SB Manager perspective in StreamBase Studio both provide a superset of the functionality of sbmonitor.

Container Property Removed From epadmin Command Output

In previous releases, the output of certain epadmin commands included a reference to a property named Container whose value was always tibco/sb. This referred to a StreamBase Runtime internal structure of interest only to TIBCO developers. The term container is heavily overloaded between StreamBase containers, Docker containers, Linux containers, and others, so the internal-only use of the term is now removed from epadmin display node, epadmin display services --servicetype node --detailed, and other commands.

Note

If your local subnet is running a mix of nodes from 10.6 and from earlier releases, the Container = tibco/sb property is still seen when epadmin reports on the earlier release's nodes.

Migration and Compatibility

This release contains the following migration and compatibility notes.

TIBCO® Streaming Now Requires Java 11 and No Longer Supports Java 8

Starting with release 10.6.0, TIBCO Streaming 10.6 runs only with and requires an installation of Oracle JDK 11.0.7 or a later JDK 11 version. See New Platform Support .

At the same time, Oracle JDK 8 is no longer supported for deploying and running EventFlow or LiveView fragments, or StreamBase applications. See Deprecated and Removed Features .

Default Method for Assigning Listener Ports in Studio Changed for EventFlow and Liveview

See the first two entries in Changes in Functionality .

StreamBase Resolved Issues

This section provides a list of errors corrected in release 10.6.0 of the TIBCO StreamBase® component of TIBCO® Streaming.

Fixed in 10.6.0
Number Resolution
TIBCO StreamBase® 10.6.0 incorporates all fixes resolved in the release 10.0 series through 10.5.0 and all fixes resolved in the release 7.7 series through 7.7.8.
SB-49056 The WITS adapter is now fixed to correctly use XML-encoded values for the heartbeat and line separator configuration values.
SB-49000 The UDP Receiver adapter now correctly uses the ISocketDataTransformer interface instead of trying to cast to the BaseDataTransformer.
SB-48954 The WITSML LogData Converter operator was not converting timestamps correctly. Time parsing is now the same between XML and the log data parser.
SB-48861 In some scenarios, the JMS Request/Reply operator would report an exception error for the field, originalMessage. This was fixed.
SB-48783 In release 10.5.0, the epadmin remove node command was not removing the System V shared memory segment if the node used System V shared memory. This was fixed.
SB-48706 Fixed a problem that caused the JMS configuration editor to throw an exception while converting configuration settings from XML to HOCON. The exception occurred when the JMS/EMS adapters were not on the project classpath. The exception is now caught, reported to the user, and the conversion continues.
SB-48515 In previous releases, string parameters in JSON format were not properly set at runtime. This was fixed.
SB-48393 If you had an engine configuration with a jvmTuning section prior 10.6.0, that section required a scheduler policy (which is actually an optional setting). This was fixed.
SB-48026 A disk-based Query Table transaction locking issue that was intermittently causing null pointers when reading valid data was resolved.
SB-47978 The LDAP Client adapter would report an NPE if the Connect At Startup option was used. This was fixed.
SB-47600 Previously, it was possible to set the parallelRegionQueues.defaultInitialBufferSize property value to exceed the parallelRegionQueues.defaultMaxBufferSize property value and still validate (unless both values were set to 16 or 32). Additional audit steps are now added to prevent the initial buffer size value from validating if it exceeds the max buffer size.
SB-45727 If a Query Table uses a Table Schema defined elsewhere (for example, .sbint file), Studio would incorrectly enable the Partition drop-down menu; trying to use it would lead to problems in trying to save the selected menu item. That problem is now fixed. When a Query Table uses a Table Schema, you must now define a partition along with the table schema's definition (for example, in the .sbint file where the table schema is defined). The Partition drop-down now is disabled in the place where the Query Table references the Table Schema, but the dropdown is enabled where the Table Schema is defined.
SB-45146 In previous releases, a red square appeared in Studio's Welcome status bar in its bottom right corner because of a missing icon in the underlying Eclipse release, and this was much more pronounced on Windows than other platforms. That issue was corrected.
