The SET CLASSCACHE command enables you to set the status of autostart for the shared class cache.
On an initial or cold start of CICS, the status of autostart is taken from the system initialization parameter JVMCCSTART. A JVMCCSTART value of YES or AUTO gives an autostart status of ENABLED, and a JVMCCSTART value of NO gives an autostart status of DISABLED. You can change the status of autostart by using the SET CLASSCACHE AUTOSTARTST command, or by using the AUTOSTARTST option on the EXEC CICS PERFORM CLASSCACHE TERMINATE command (or the equivalent CEMT command) when you terminate the shared class cache.
When you change the status of autostart for the shared class cache while CICS is running, subsequent CICS restarts use the most recent settings that you made using the CEMT or EXEC CICS SET CLASSCACHE command (or the CEMT or EXEC CICS PERFORM CLASSCACHE command), unless the system is INITIAL or COLD started, or the system initialization parameter JVMCCSTART is specified as an override at startup. In these cases, the setting from the system initialization parameter is used.
