PERFORM SNAP API
Causes the statistics for a named resource type to be recorded.
Syntax
Description
PERFORM SNAP API obtains a dump and continues running the application program.
Use this API to obtain a
system dump from the program while the CICS® application continues to run. In effect,
you obtain a snapshot of the CICS region. CICS always returns a response code 0 (NORMAL),
whether or not the dump is successful. To generate a SNAP Dump by using EXEC CICS PERFORM
SNAP API, set the attribute SysDump to "yes" in RD stanza.
Note: The use
of EXEC CICS PERFORM
SNAP prevents all other tasks from running, so other terminal users can have
long delays in response.
Options
- DUMP
- Specifies that CICS produce a dump. DUMP is the default, so you do not have to specify this parameter.
