If you see Java heap space messages in the ssm0.log, the resolution is to increase the amount of memory allocated to the Policy Manager.
The policy manager .ini file defines how much memory can be allocated to the application. It is normally located in the installation path of the Policy Manager but it could be anywhere you specified during the installation. For example :
C:\Program Files (x86)\CA Technologies\CA API Gateway Policy Manager 9.2.00\CA API Gateway Policy Manager.ini
or for older versions:
C:\Program Files (x86)\Layer 7 Technologies\Layer 7 Policy Manager 8.2.00\Layer 7 Policy Manager.ini
- Make a backup copy of the ini file and save it into a backup directory of your choice
- Edit the original file with notepad or some other text editor.
- Change "-Xmx256M" to "-Xmx512M".
Restart the Policy Manager
By default, Automatic policy validation is enabled. If it is causing problems you can disable the automatic validation via the following steps in Policy Manager
