1. Navigate to the tomcat/bin/app folder in the Chronicall/ACR directory
   • Default locations

     • C:\Program Files (x86)\Xima Software\Chronicall\bin\app

     • C:\Program Files\Chronicall\bin\app

     • C:\Program Files\Avaya Call Reporting\bin\app

2. Right-click and run ChronicallServerw.exe as an Administrator
3. Click the Java tab
   • Java’s “Initial memory pool” and “Maximum memory pool” are listed at the bottom
     • We always leave the Initial memory pool to its default value
     • Most new installs will default to Maximum memory pool of 384, and this can be increased, and is recommended to increase it in multiples of 1024 (1024, 2048, 3072, 4096, etc)
   • NOTE: 32-bit versions of Chronicall (Shoretel/Mitel and 32 bit Chronicall installs) have a “Maximum memory pool” value of 1024 MB
   • 
4. Adjust your “Maximum memory pool” up to the amount you need.  It is recommended that you add RAM in multiples of 1024 MB.  So if you have 2 GB free on the server, you could set your Maximum memory pool to 2048 (2 x 1024)
   • Make sure your server has the available RAM resources before making this change.  You don’t want to tell Chronicall to use more RAM than the server has available
5. You will need to restart Chronicall\ACR before your changes will take effect
