The CICSplex JVM Classcache Details attributes report information about the size, amount of free space, date and time when it was started, and related profile name for the given class cache.
Autostart Indicates the current status of autostart for the shared class cache. These are the values:
Cache Free Indicates the free space in the shared class cache, in kilobytes.
Cache Size Indicates the size of the cache in kilobytes.
CICS Region Name Indicates the job name or modify ID of the CICS region being monitored. Each CICS region in a z/OS operating system has a unique name. This name is an alphanumeric string, with a maximum of eight characters, and case-sensitive. CICS region names are always in uppercase characters.
Number of old caches Indicates the number of old caches that are still present in the region because they are waiting for worker JVMs that are dependent on them to be phased out. If the status of the current shared class cache is STOPPED, and worker JVMs are still dependent on it, then that shared class cache is included in the number of old shared class caches.
Origin Node Is the combination of the z/OS System ID (SMFID) and the CICS region name. The value format is an alphanumeric string, maximum 32 bytes, and case-sensitive.
When a situation is true, the system compares the origin node name in the attribute to the names of managed systems assigned to the item. If the origin node name matches the name of a managed system, the status of the item changes accordingly. If the names of the origin node and the managed systems do not match, the status of the item remains unchanged.
Phasing Out Indicates the number of JVMs that are phasing out. This is the number of working JVMs that are dependent on an old shared class cache and are being phased out. If the status of the current shared class cache is STOPPED, then any worker JVMs that are still dependent on it are included in the number of worker JVMs being phased out.
Profile Indicates the name of the JVM profile used for the master JVM. The name of the JVM profile that is to be used to start the master JVM. If the master JVM is in use, this is the name of the JVM profile for that master JVM.
Reuse Status Indicates the reuse status of the master JVM. These are the valid values: RESET, REUSE, or UNKNOWN. The RESET value indicates that the JVMs can be reused after they have been reset. The REUSE value indicates that the JVMs can be reused without being reset. The UNKNOWN value indicates that the class cache has not been started.
Start Date Indicates the date when the current class cache was started. This is an alphanumeric string, with a maximum of 10 characters.
Start Time Indicates the time when the current class cache was started. This is an alphanumeric string, with a maximum of eight characters.
Start Time and Date Indicates the time and date when the current shared class cache was started. The valid format is an alphanumeric string, maximum 16 characters.
Status Indicates the current status of the shared class cache. These are the values:
System ID Indicates the four character name that uniquely identifies an active z/OS operating system within a given CICSplex. The value format is an alphanumeric string, maximum four characters, and case-sensitive. z/OS System IDs are always in uppercase characters.
Total JVMs Indicates the number of working JVMs in the CICS region that are dependent on the shared class cache.
