After you have activated an SMS configuration, you can use the
SET SMS or SETSMS operator commands to specify SMS parameters, as
follows:
- Use the SET SMS command to start SMS if it is not started at IPL
or to change SMS parameters if SMS is already running. The SMS parameters
are taken from the IGDSMSxx member in SYS1.PARMLIB.
- Use the SETSMS command when SMS is already running to change a
single SMS parameter. You enter the parameter to be changed on the
command line.
Note: Some parameters in the IGDSMSxx parmlib member are read
at IPL time, but do not have any effect unless it is the first time
the parameters are specified for a new configuration. As indicated
in the section "Changing IGDSMSxx Parameters to Support the Coupling
Facility" in
z/OS DFSMSdfp Storage Administration,
you must issue the SETSMS command for any changes to take effect.
In particular, the values used by VSAM RLS for the following keywords
are remembered from last initialization, but not overridden by the
IGDSMSxx specifications at IPL time unless the SETSMS command is issued.
- CF_TIME
- DEADLOCK_DETECTION
- RLS_MAXCFFEATURELEVEL
- RLS_MAX_POOL_SIZE
- RLSABOVETHEBARMAXPOOLSIZE
- RLSFIXEDPOOLSIZE
- SMF_TIME
