Multi-system considerations
Issuing the SETSMS command only changes the CICS® VR parameter setting on the system that processes the command.
Use the ROUTE command to issue the SETSMS command on multiple systems.
For example, issuing the following command changes the CICSVR_DSNAME_PREFIX
setting on all systems in the sysplex:
ROUTE *,ALL,SETSMS CICSVR_DSNAME_PREFIX(DWW)
See z/OS® MVS System Commands for further information about the ROUTE command.
