These statistics can be accessed online using the EXEC CICS® COLLECT STATISTICS JVMPOOL command, and are mapped by the DFHSJGDS DSECT. For programming information about the EXEC CICS COLLECT STATISTICS command, see the CICS System Programming Reference manual.
This section contains the following statistics:
DFHSTUP name | Field name | Description |
---|---|---|
Total number of JVM program requests | SJG_JVM_REQS_TOTAL | is the total number of JVM program requests.
Reset characteristic: reset to zero
|
Current number of JVMs | SJG_CURRENT_JVMS | is the current number of JVMs.
Reset characteristic: not reset
|
Peak number of JVMs | SJG_PEAK_JVMS | is the peak number of JVMs.
Reset characteristic: reset to current
|
Number of JVM program requests -- Reset specified | SJG_JVM_REQS_RESET | is the number of requests to run a program in a resettable
JVM.
Reset characteristic: reset to zero
|
Number of JVM program requests -- Reuse specified | SJG_JVM_REQS_REUSE | is the number of requests to run a program in a continuous
JVM.
Reset characteristic: reset to zero
|
Number of JVM program requests-- JVM initialized | SJG_JVM_REQS_INIT | is the number of JVM program requests where the JVM was
initialized.
Reset characteristic: reset to zero
|
Number of JVM program requests --JVM mismatched | SJG_JVM_REQS_MISMATCH | is the number of JVM program requests that required a
resettable or continuous JVM, but for which there was no JVM already initialized
with the same JVM profile.
Reset characteristic: reset to zero
|
Number of JVM program requests--JVM terminated | SJG_JVM_REQS_TERMINATE | is the number of JVMs that have been terminated.
Reset characteristic: reset to zero
|
Total number of Class Cache JVM requests | SJG_JVM_REQS_CACHE | is the total number of Java™ programs that requested a JVM that
uses the shared class cache.
Reset characteristic: reset to zero
|
Current number of Class Cache JVMs | SJG_CURRENT_CACHE_JVMS | is the number of JVMs currently in the pool that use the
shared class cache, so are worker JVMs. JVMs use the shared class cache if
they were created using JVM profiles that specify CLASSCACHE=YES. This count
includes both worker JVMs that are in use by a Java program, and worker JVMs that are
awaiting reuse.
Reset characteristic: not reset
|
Peak number of Class Cache JVMs | SJG_PEAK_CACHE_JVMS | is the peak number of JVMs in the JVM pool that used the
shared class cache.
Reset characteristic: reset to current value
|
