Memory Panel
The Studio Manager Memory panel displays a graphical log of TDV memory usage.
You can adjust the information displayed in the I/O panel by selecting or clearing the check boxes at the bottom of the panel:
• Total Memory check box—The actual TDV usage levels.
— Maximum—Available computational memory.
— Throttle—Displays the maximum throttle memory available. TDV has a runtime configuration setting for a wait queue minimum memory threshold which is visible as the “Throttle” on the Memory console. If actual memory usage crosses the minimum threshold, all new queries are queued until more memory is available. This threshold is meant to avoid potentially fatal out of memory errors on the server.
• Managed Memory check box—Managed memory is a configurable percentage of that total made available to the Java Virtual Machine (JVM).
— Maximum—Displays the maximum total memory available as set by the Available Managed Memory configuration parameter.
You can use the Free Unused Memory button at the bottom of the panel to free unused memory. This action starts the Java VM garbage collection cycle that is started automatically when the maximum managed memory level is exceeded. You must have the Modify_All_Status right to use this button.
You can also monitor memory usage in Manager. See
Memory Log for more information.
