You can dynamically change the value of any of the CICS® VR
PARMLIB parameters specified in the active IGDSMSxx member
without updating the member itself.
The SETSMS operator command, followed by the CICS VR
parameter name and value, can be issued for each of the CICS VR
parameters to change the current setting. However, note that some
of the dynamically changed parameters are not used by CICS VR
until the next time the CICS VR server address space is
started.
For example, if the CICS VR server address space
is active when the SETSMS CICSVR_DSNAME_PREFIX(PROD) command is issued,
the CICS VR server address space must be terminated, then restarted
for CICS VR to use the value specified in the SETSMS command. Refer
to CICS VR SETSMS commands for information
about when each CICS VR SETSMS command takes effect.
Note: Any values changed by issuing the SETSMS command are no longer
available after a system has been reinitialized, re-IPL'd. The first
time that the CICS VR server address space is started on a
system after the system has been re-IPL'd, CICS VR
uses the settings specified in the active IGDSMSxx member
of SYS1.PARMLIB.
Below is a list of the available SETSMS commands that can be issued
to change CICS VR parameters without updating the active
IGDSMS
xx member:
SETSMS CICSVR_INIT(YES | NO)
SETSMS CICSVR_GRPNAME_SUFFIX(suffix)
SETSMS CICSVR_DSNAME_PREFIX(hlq.slq)
SETSMS CICSVR_RCDS_PREFIX(hlq.sql)
SETSMS CICSVR_ZZVALUE_PARM(zzvalue)
- Examples
-
- SETSMS CICSVR_INIT(NO)
- Changes the CICS VR initialization parameter to NO on the
system that processed the command. If CICS VR
is active on the system when this command is issued, CICS VR
remains active. After this command is issued, and CICS VR
is terminated, you is not able to restart the CICS VR
server address space until the CICSVR_INIT parameter is reset to YES.
- SETSMS CICSVR_GRPNAME_SUFFIX(TEST)
- Changes the CICS VR XCF group name parameter to TEST on
the system that processed the command. The specified value is activated
the next time the CICS VR server address space is
started.
- SETSMS CICSVR_DSNAME_PREFIX(PROD.ONE)
Changes the CICSVR_DSNAME_PREFIX parameter value
to PROD.ONE on the system that processed the command. The specified
value is used for DWWMSGA, DWWMSGB, DWWDMSG, and DWWDUMP data sets
naming convention the next time the CICS VR server address space is
started. However, CICS VR uses the specified value
immediately for DFSMSdss logical copy notification support
and change accumulation data sets without restarting the CICS VR
server address space
- SETSMS CICSVR_RCDS_PREFIX(DWW2)
- Changes the RCDS prefix value used in the RCDS naming convention
to DWW2. The specified value used by CICS VR
the next time the CICS VR server address space is
started.
