Summary

Starting Jazz Team Server on IBM i will not restart after Java maintenance. The following error is generated: JVMJ9VM015W Initialization error for library j9gc26(2)

Details

After applying Java PTFs on IBM i (V6R1 : SF99562, V7R1 : SF99572), the Jazz Team Server does not start with WebSphere Application Server v8 or v8.5. The following messages are listed in the server native_stderr.log file: JVMJ9VM015W Initialization error for library j9gc26(2): Failed to instantiate heap; 6G requested Unable to create Java Virtual Machine.
Note: This problem does not occur when you run the Jazz Team Server with WebSphere Application Server v7.

Workaround

To work around the problem, edit the WebSphere Application Server profile server.xml file. You can find the file in a directory path similar to the following example:

/QIBM/UserData/WebSphere/AppServer/V85/BASE/profiles/JTS/config/cells/I7ADT05_JTS/nodes/JTS_NODE/servers/JTS/server.xml

Edit the file and change this parameter:

genericJvmArguments=”-Xmn500m -Xgcpolicy:gencon -Xcompressedrefs -Xgc:preferredHeapBase=0x100000000″

To match this example:

genericJvmArguments=”-Xmn500m -Xgcpolicy:gencon -Xcompressedrefs -Xgc:preferredHeapBase=0x200000000″

After you save the change, restart the server.
