Issue/Introduction
Resolution
Modify the Virtual Memory. Set up the start script when not running as a Windows service.
==========================================================
1). Open the file <installation dir>/tomcat/bin/setenv.bat/.sh in a text editor.
2). Locate the line that sets the variable JAVA_OPTS:
set JAVA_OPTS=-server -XX:+DisableExplicitGC -XX:MaxPermSize=256M -Xms512M -Xmx1536M
3). Alter the -xms and the -Xmx values -Xms512M -Xmx1536M to the amount of memory you wish to allocate.
4). Save the file.
5). Restart the server.
To set up the start script when running as a Windows service.
=================================================
1). Stop the TIBCO Spotfire Server service.
2). Go to the <installation dir>/tomcat/bin directory.
3. Run the command: service.bat remove.
4). Edit the <installation dir>/tomcat/bin/service.bat file.
5). Look for the entries: --JvmMs 512 --JvmMx 1536 .
6). Alter 512 and/or 1536 to suitable memory values (in megabytes).
7). Launch the command prompt and run the following command: "service.bat install" by navigating to <Spotfire Server install folder>\tss\<version>\tomcat\bin.
8). Start the TIBCO Spotfire Server service.
NOTE: For 32-bit Windows operating systems, we recommend never going above 1300M for the heap size. If you set the value too high, the server will fail to start. This is a Java/OS limitation and has nothing to do with Spotfire. If you are running the Tomcat Service as Service account, ensure that you update the service account after step 7 above.
