Altering the behavior of a running Capture program
You can dynamically change the value of one or more Capture operating parameters. The changes are not saved in the IBMSNAP_CAPPARMS table, but are used until you stop the Capture program or supply new values.
About this task
z/OS®, Linux®, UNIX, Windows: You can change the following Capture parameters while the Capture program is running:
- autoprune
- autostop
- commit_interval
- lag_limit
- logreuse
- logstdout
- memory_limit
- monitor_interval
- monitor_limit
- prune_interval
- retention_limit
- sleep_interval
- term
- trace_limit
Restriction on z/OS: The amount of memory that the Capture program can
use to build messages is determined when the Capture program starts, based on the value of the
memory_limit parameter and the REGION size that is specified in the JCL. The
value of memory_limit cannot be altered with the Capture program is running. To
change the value you must first stop the Capture program.
IBM® i: You can override the values for the following operational parameters for a given Capture schema:
- CLNUPITV
- FRCFRQ
- MEMLMT
- MONLMT
- MONITV
- PRUNE
- RETAIN
- TRCLMT
When you change the values, the effects might not be immediate for all parameters.
Procedure
To alter the behavior of a running Capture program, use one of
the following methods:
| Method | Description |
|---|---|
|
MODIFY or asnccmd chgparms system command (z/OS, Linux, UNIX, Windows) |
This method does not show the current values of the parameters. |
|
OVRDPRCAPA system command (IBM i) |
Use the Override DPR Capture attributes (OVRDPRCAPA) command to alter the behavior of a running Capture program. |
