Java Heap Space Out Of Memory Error

Symptom:

When I try to import a large number of CIs from a domain manager, I receive the Java heap space OutOfMemory error.

Solution:

If there are a large number of CIs, relationships, and services to be imported from a domain manager, the IFW may run out of allocated JVM heap space and stop responding. This error appears as a "java.lang.OutOfMemoryError:Java heap space" exception in the SOI_HOME\jsw\logs\SAM-IntegrationServices_wrapper.log file. You may need to increase the IFW JVM heap space if this situation occurs frequently to process all imported CIs and relationships.

Do any of the following tasks to manage the IFW JVM heap space:

• Increase the JVM heap size in the IFW (default is 1 GB) as follows:
  • Stop the CA SAM Integration Services service.
  • Increase the wrapper.java.maxmemory value (in MB) in the SOI_HOME\jsw\conf\SAM-IntegrationServices.conf file.
  • Start the CA SAM Integration Services service.
• Turn off the getRelationshipsAtStartup control for connectors with a large number of CIs and relationships. This operation prevents rediscovery of all relationships every time the connector starts. Importing services still imports all relationships with this control turned off.
