These instructions are for Ignite PI versions 4.3 and below.

 

If monitoring a large number of instances, it may be necessary to increase the amount of memory that is allocated to Ignite.  By default, Ignite will take a minimum of 128MB but is allowed to grow to 512MB.  On systems with more than 20 monitored instances, it usually makes sense to bump this up to a maximum of 1GB.

 

Windows Instructions (for Ignite PI Server running as a Windows service)

  1. Edit the file iwc\tomcat\bin\service.bat. 
  2. Search the file for the string "--JvmMx" .  It will likely be followed by "0x200".  This is hexidecimal for 512.
  3. Change it to 0x300 to increase the maximum to 756MB.  Change it to 0x400 to increase the maximum to 1GB.
  4. Recreate the Ignite PI Server service by running 2 batch files that were installed with Ignite PI:
  • removeWindowsService.bat
  • createWindowsService.bat
     

Windows Instructions (for Ignite PI Server running in a window)

  1. Edit the file iwc\tomcat\bin\catalina.bat. 
  2. Search the file for the string "-Xmx".  It will likely be followed by "512m"  (for 500MB).
  3. Change it to "-Xmx756m" to increase the maximum to 756MB.  Change it to "-Xmx1000m" to increase the maximum to 1GB.
  4. Restart the Ignite PI Server by running 2 scripts that were installed with Ignite PI:
  • shutdown.bat
  • startup.bat

 

Unix/Linux Instructions

  1. Edit the file iwc\tomcat\catalina.sh
  2. Find the line "set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m" and change 512m to 1024m
  3. Restart the Ignite PI Server by running 2 scripts that were installed with Ignite PI:
