Issue/Introduction
We see the following error in jcs_daily.log
java.lang.OutOfMemoryError: Java heap space
Environment
Release : 14.x
Component : IdentityMinder(Identity Manager)
Cause
One possible reason is JVM memory allocation is too small.
Resolution
If you have enough RAM resources in the Connector Server machine you can increase JVM memory allocation for JCS.
On Windows please edit the following registry values
HKEY_LOCAL_MACHINE/SOFTWARE/Wow6432Node/ComputerAssociates/Identity Manager/Procrun
2.0/im_jcs/Parameters/Java/JvmMs
HKEY_LOCAL_MACHINE/SOFTWARE/Wow6432Node/ComputerAssociates/Identity Manager/Procrun
2.0/im_jcs/Parameters/Java/JvmMx
JvmMs is the minimum memory allocation. JvmMx is the maximum memory allocation.
On UNIX, create a file named jvm_options.conf in the Connector Server data folder with the following Java arguments.
-Xms256M -Xmx2048M -d64
-Xms
Specifies the minimum heap memory allowed for CA IAM CS
Example: -Xms256M specifies that the minimum heap memory allowed for CA IAM CS is 256 MB.
-Xmx
Specifies the maximum heap memory allowed for CA IAM CS.
Example: -Xmx2048M specifies that the maximum heap memory allowed for CA IAM CS is 2048 MB.
-d64
Specifies that the JVM is run in a 64-bit environment.
Restart JCS after the above modification.
On Virtual Appliance, please edit the following file
/opt/CA/IdentityManager/ConnectorServer/data/jvm_options.conf file
Restart JCS after changing the file.
