and related options are on Eclipse Open J9 to enable the shared class cache.-XX:MaxPermSize
is set on HotSpot Java SE 7 to increase the size of the permanent generation space.-Djava.awt.headless=true

:
Code | Explanation |
---|---|
0 | This code indicates successful completion of the requested operation. |
1 | This code indicates invocation of a redundant operation, such as starting a started server or stopping a stopper server. 1 might also be returned if the JVM options that were used are not valid. |
2 | This code indicates that the server does not exist. |
3 | This code indicates an unsupported action was called on a running server. For example, the server is running when the package action is called. |
>=20 | Exit codes that are greater than or equal to 20 indicate that an error occurred while performing the request. Messages are printed and captured in log files with more information about the error. |
