Maximum Heap Size

Maximum Heap Size

The upgrade process resets the Model Repository Service maximum heap size to 4 GB. After the upgrade, reset the maximum heap size property to the value to which it was set prior to the upgrade, or to the setting that Global Customer Support recommended for your environment.
Prior to Model Repository Service upgrade, set the value for -Xss parameter in the JVM Command Line Options to 1m. After the upgrade, reset the -Xss parameter value to the pre-upgrade value. The default value for -Xss parameter is 512k.
Effective in version 10.1, the property
MaxPermSize
 in the JVM Command Line Options is replaced with
MaxMetaspaceSize
.
To reset the maximum heap size, select the service in the
Domain Navigator
, click the
Properties
 view, and expand
Advanced Properties
. Set the
Maximum Heap Size
 property to the pre-upgrade value. Set the
MaxMetaspaceSize
 property to the minimum of 512 MB.
