To view and set StreamBase Studio preferences, invoke StreamBase Studio page.
→ in the main menu (Windows) or → (macOS) You can control basic Eclipse settings with various pages in the Preferences window, and can manage StreamBase-specific settings, by opening theFor information on Project Property settings, see StreamBase Project Properties.
Preferences are preserved separately for each Studio workspace. You can keep more than one workspace with different preference settings.
Use the
→ → → → panel to set color and font options for the components listed therein.The following preferences can be set in the main StreamBase Studio panel of → .
Option | Description | Default |
---|---|---|
StreamBase Installation Directory | The root directory where the current release of StreamBase is installed.
This is where Studio looks for global operators and adapters at startup, and where Studio finds the StreamBase and LiveView Server executables for local launches. If you modify this setting, restart Studio for the change to take effect. Do not change this setting, except under the direction of StreamBase Technical Support. |
See Default Installation Directories |
Automatic Perspective Switching |
A perspective is a collection of Eclipse views that are opened together to perform a task. StreamBase Studio can be set to automatically switch between perspectives on certain triggering events. The setting for Switch to SB Test/Debug perspective when running an application applies only to Studio's default launch configuration. The setting for Switch to SB Authoring perspective when stopping an application applies to running all StreamBase applications, whether started with the default launch configuration or a custom one. |
Both options enabled. |
Auto-save Options | When you attempt to run an application, StreamBase Studio checks for unsaved files and resources in the current project, which
must be saved before proceeding. This preference controls how and when resources are saved before running applications. The
options are:
When either of the first two options is set, the Ask me next time option is no longer shown in the Preferences page. To make it visible again, click Restore Defaults, then close and reopen StreamBase Studio. |
Ask me next time |
Advanced | ||
Allow loading deprecated Global Operators/Adapters | When disabled (default), Studio does not load deprecated operators or adapters and does not display them in the Insert Adapter
or Insert Java Operator dialogs. When enabled, deprecated operators or adapters are loaded and displayed in the those dialogs.
An operator or adapter is marked deprecated with the Java annotation TIBCO StreamBase occasionally marks certain components as deprecated to encourage the use of newer components. If you are working on a legacy application and need to continue using a deprecated component, enable this setting. With this setting disabled, the display of EventFlow applications that were saved with now-deprecated components is not affected. However, such applications cannot pass typechecking and cannot be run in Studio, because the code that underlies the deprecated components was not loaded. You can continue to work on such applications by enabling this option, or by upgrading the deprecated components with their replacements. |
Enabled. |
Use custom Component Exchange URL | When unspecified, the default behavior for the StreamBase Component Exchange dialog is to retrieve its list of available components from streambase.com. Use this field to specify an alternate URL that
contains an in-house or company-specific location for downloading StreamBase components. Contact TIBCO Software Inc. Technical Support for guidance in setting up an in-house component exchange site.
Site-specific Component Exchange URLs can use the HTTPS protocol, in which case Studio prompts you for access credentials on the specified server. If you supply a URL that begins with HTTPS or FTP, Studio automatically prompts for credentials. If you supply a URL for another
protocol, you can force authentication prompting for that protocol by setting the Java property |

Use the
→ → panel to set options for the SB Authoring perspective. The EventFlow Editor options do not affect the StreamSQL Editor.Option | Description | Default | |
---|---|---|---|
EventFlow Editor | |||
Automatically typecheck components |
Specifies that components are automatically typechecked as you build your EventFlow application. Disable this preference to suppress automatic typechecking. See also the related check box to enable Typecheck EventFlow Editors in background on the Typechecking panel, described below. This preference has no effect on StreamSQL applications, which are always typechecked automatically. See Typechecking for more on StreamBase typechecking. |
Enabled | |
Skip deep typechecking of strict module references and extension points | Enable to avoid full-depth typechecking of Extension Points and Module References that have all output schemas explicitly set. This can greatly speed up typechecking for some large applications. | Disabled | |
Show tooltips | Specifies that summary information about each component is to be shown when you hover the mouse pointer over an icon or arc
on the canvas. For example:
|
Enabled | |
Automatically select newly inserted components | Specifies that components newly placed on the EventFlow canvas are automatically selected. This automatically opens the new component's Properties view. | Disabled | |
Automatically edit names of newly inserted components. | With this check box enabled (the default), when you drag a component icon to the EventFlow canvas (or use a keyboard shortcut
to accomplish the same thing), the new component's name is selected and an edit cell open, ready for you to start typing to
change the component's name. Press Enter to close the edit cell with your new name, or press Esc to exit the edit cell without saving your edits.
This feature adds an extra step to keyboard shortcuts that place new components on the canvas. For example, to add a Map operator, the keyboard shortcut is (at minimum) O M Enter with this option enabled, but is O M with this option disabled. You may prefer to disable this option temporarily when entering a long sequence of keyboard shortcuts to quickly fill a new canvas, then re-enable it. See Studio Keyboard Shortcuts. |
Enabled | |
Use middle mouse button to scroll instead of pan | This option refers to a mouse with three buttons, or with a scroll wheel that can be used as a middle button. With this option disabled, hold down the middle button or scroll wheel (without scrolling the wheel) to move the entire EventFlow drawing within the frame of the canvas window. With this option enabled, holding down the middle button or scroll wheel lets you scroll in four directions, exactly like using the canvas' scrollbars. | Disabled | |
Save and restore view location and zoom factor | When enabled, Studio preserves the current zoom level of EventFlow Editor sessions and the position of components relative to the top left corner of the EventFlow Editor canvas. These display features are saved when you save the EventFlow application, and are restored when you re-open the application. | Enabled | |
Center canvas on selection during navigation |
When enabled, auto-centers the canvas on components selected when navigating in two ways:
With this check box cleared, Studio highlights the selected component on the canvas, but does not center the canvas. If the component is offscreen when selected, Studio moves just enough of the canvas to make the component visible. |
Enabled | |
Hide Control to toggle to/from text fields in Java Operator Properties |
When cleared, the check box, radio button, and drop-down menu controls in Java operator and adapter Properties views display a Alt+F2 (Option+F2 on Mac) replaces the check box, radio button, or drop-down menu with a text field, in which you can enter: icon () to the right of their text labels. Clicking the icon or typing
When this preference is enabled, you can still convert a UI control to a text box with the keyboard shortcut when the control has focus. For additional details, see Parameterizing Java Operator and Adapter Properties. |
Enabled | |
For new applications, store layout information in: | Controls how graphical layout and EventFlow semantic elements are stored in EventFlow source files. This setting takes effect
only for newly created EventFlow applications.

Outline View | |||
Show empty categories (EventFlow Editor) | Displays container folders in the Outline view for every component type, even if the application contains no instances of some components. By default, the view contains only Outline view categories for existing components. | Disabled | |
Palette View | |||
Show separate entries for Input, Output Adapters and Java Operators | The Palette view by default contains a single icon labeled Adapters, Java Operators that you drag to the canvas. Once there, a dialog opens that lets you select one or more adapters or global Java operators
for placement on the canvas.
In previous releases, this single Palette view icon was shown as four separate icons: Input Adapter, Output Adapter, .NET Operator, and Java Operator. Select this check box to restore those four separate icons to the Palette view. |
Disabled |

---|---|---|---|
Render tiles around component icons |
Enable this option (default) to show tiles around component icons, whose left and right edges are where ports attach. Disable to remove the tiles. The selection outline still appears with or without tiles. |
Enabled | |
Render selection without filled outline |
When disabled (default) the selection outline is filled with light blue as shown above. When enabled, the selection outline shows as an unfilled dotted line, as follows: |
Disabled | |
Show mouse hover feedback |
When enabled (default), shows a yellow information box for a component when hovering the mouse over it. |
Enabled | |
Use animations | When enabled (default), shows an animation effect when you use the Rearrange components and arcs function ( button or Ctrl+L). | Enabled | |
Use simple colors instead of gradients | When enabled, tiles and selection outlines are shown with flat colors. When disabled (default), colors are shown as gradients. | Disabled | |
Hide adapter tiles when there is only one port | When enabled (default), adapters that have only one input port or only one output port are shown without an enclosing tile. When disabled, tiles are always shown for adapters. | Enabled | |
Show indicator for components that run in a separate thread |
When enabled (default), if a component has the Run this component in a parallel region option selected in its Properties view, the component is shown with a circle inside the bounds of the icon. When disabled, the circle decoration is not shown, and there is no visual indicator of the component's separate thread state. |
Enabled | |
Use slanted arcs during arc routing and auto-layout | When enabled (default), arcs placed by the Layout Application (Ctrl+L) and Reroute Arcs (Ctrl+Alt+L) functions are shown with an angled slant between components. When disabled, arcs are only placed horizontally or vertically, with right angles for every direction change. | Enabled | |
Ignore label widths during auto-layout | When disabled (default), EventFlow modules are laid out during auto-layout or arc routing by taking the widths of the names of each component into account. When enabled, text widths are ign | Disabled | |

Studio maintains a cache of compiled build artifacts when you run a module in Studio, and uses cached items when re-launching the same module. The cache is automatically maintained such that any portions of an application are rebuilt if the underlying EventFlow or StreamSQL code changed, but unchanged portions are read from the cache.
You can control the location of the compiler cache and its persistence with three options:
- Use a temporary directory for each Studio session
-
This is the default setting. The cache is written to a directory created in the system temporary directory determined as described for the TMP environment variable.
- Use a workspace specific directory, and persist cache across sessions
-
The cache is written to a directory in the
.metadata
folder of your Studio workspace. - Persist cache at a specific directory
-
Use the

Launch Options | ||
Default Launch server | Either Local Server or Remote Server. This preference affects the Run and Debug launch modes (especially in conjunction with the Run and buttons in the Studio toolbar). This setting has no effect on Trace mode launches, or using the Trace toolbar button.
Select Remote Server to specify that using Run or Debug launch mode always runs the current StreamBase application against a remote server instance. Specify the default host name and remote user name elsewhere on this Preferences page. The default is to run against a local server instance on the machine running StreamBase Studio. |
Local Server |
Open editor for running StreamBase Application when launched | The running application opens in the EventFlow or StreamSQL editor, as appropriate for the selected application. | Enabled |
Remote Options | ||
Remote options, if set, are used as workspace defaults in the StreamBase launch configuration wizard. | ||
Default remote server | If you select the Remote Server option above, enter the name or IP address of the host UNIX machine where the StreamBase software is installed, and an SSH
server is running. The specified host must be configured as described in Configuring UNIX Servers for Remote Studio Access.
If your network administrator gave you a specific port number, enter it after the server name and a colon. The port is for
the SSH server running on the specified host, not StreamBase Server. (For example: |
Empty |
Default remote user | Enter a user name that will allow you to connect via SSH to the specified remote server. | Your current local user name is entered by default. Change this, if necessary, to reflect the correct user name for the remote server. |
Use SSH tunneling for all server connections |
Enable SSH tunneling for the connection to the remote host UNIX machine where StreamBase is installed. When you launch an application to run on a remote server, Studio normally detects whether tunneling is required (for example, when the server host has a firewall). NoteBefore connecting from StreamBase Studio to a remote UNIX host machine, the remote system must have an SSH daemon running with TCP port forwarding enabled. Follow the instructions in Configuring UNIX Servers for Remote Studio Access. If you do not enable tunneling and StreamBase later detects that it is needed, StreamBase displays a prompt that gives you another chance to enable it. Click in the dialog to enable SSH tunneling for the connection to StreamBase Server's host machine. If you are not certain, contact the administrator of the host machine. |
Disabled |
SSH Authentication |
Either Password Authentication or Keyboard-Interactive. Specify Password Authentication, the default, to connect to a server whose SSH configuration allows it. If the server hosting StreamBase Server has an SSH configuration that allows keyboard-interactive authentication, select Keyboard-Interactive. Some servers, including Solaris servers, may be configured to only allow keyboard-interactive SSH authentication. In this case, you must select Keyboard-Interactive to connect to StreamBase Server running on such hosts. If your Linux host runs OpenSSH as its SSH implementation, you specify keyboard-interactive authentication by setting |

---|---|---|
Application Input/Output Views | ||
Input View tuple buffer size |
When you run an application and enqueue data, the number of input tuples can become quite large. It can be helpful to limit the number of tuples in the Application Input view's display buffer. When the limit is reached, newer tuples are kept in the view while older tuples are allowed to scroll off the view. The specified display buffer size applies to the total number of tuples in the Application Input view, from the total of all input streams. |
400 tuples |
Output View tuple buffers size |
Same as above, but for output tuples in the Application Output view. The specified display buffer size applies to the display of each output stream, as well as when (All Output Streams) is selected. |
400 tuples |
Output View highlight color | Specifies the color applied to matching rows in the Application Output view when you have specified a filter in the Application Output Filter dialog, and have specified the highlight selected option in the Results section of that dialog. | #FFFF00, a solid yellow |
EventFlow Debugger | ||
Bring Variables view to front when a StreamBase breakpoint is hit | By default, the Variables view shares the lower-left quadrant of the SB Test/Debug perspective with the Application Output, Application Input, and Profiler views. When this option is selected, the Variables view is brought to the front when the EventFlow Debugger hits a breakpoint. You can also toggle the StreamBase button in the Variables view's toolbar to specify the same preference. |
Enabled |
Field Value Formatting Options | ||
Indicate nulls using | The null token is used in editors and views when a field contains no value. You can substitute any string to indicate nulls. |
"null" |
Display blobs as | In the Application Input and Application Output views, and elsewhere in Studio, show the first few characters of blob fields as hexadecimal values or ASCII characters. | Hex |
Maximum blob characters to display | Specifies the number of bytes of blob fields to display as character data in the Application Output view. | 16 |
Server Port | ||
Default Port |
Specifies the default TCP port number used by StreamBase Server when launched from Studio, on which to listen for client connections. An explicit server port number specified in this application's server configuration file can override this preference setting. See <server> for more on the configuration file. |
10000 |
