When a resource is published or when a Transformation Editor or Data Lineage panel is opened in TIBCO Data Virtualization (TDV) Studio, it 'may' consume copious amounts of studio memory. If the Studio memory is set to default "1024MB", it could lead to insufficient memory situation to perform any additional tasks in Studio or the following error message could popup:



The studio memory can be monitored at the bottom right corner of the Studio application. This article describes how to increase the memory in order to prevent the out of memory errors of studio.

Short-term solution: 
In Studio, click "Run Garbage collector" button located at the bottom-right corner of the application. 
Note: This activity does not require a restart of the Studio application. 

Screenshot for reference:


This will run the GC to free any unused memory for the Studio application. If this does not help free up sufficient memory, look out for increasing the Studio memory as mentioned in the long-term solution. 

Long-term solution:
To increase the memory allocated for Studio application, perform the following steps:
(1) On the client machine which runs Studio, navigate to the installation directory of Studio and Open Studio by executing the studio.bat file. Default location is "C:\TIBCO\[TDV_server_vesion]\bin".
(2) In Studio, navigate to Edit -> Options -> Maximum Memory.



(3) Update the value for 'Maximum memory' to the desired value. Default is 1024 MB.
(4) Select the checkbox 'Restart Studio after applying memory settings'. Click OK. This will close the Studio application automatically. 

A warning like below may appear which can be safely ignored:


(5) Re-open the Studio application and at the bottom right corner you should see the new memory value that is set.
