2. Activating an SMS configuration from the operator console:
– From the operator console, enter the command:
SETSMS {ACDS(YOUR.OWN.ACDS)} {SCDS(YOUR.OWN.SCDS)}
Activating the configuration means that information is brought into the SMS address space
from the ACDS.
To update the current ACDS with the contents of an SCDS, specify the SCDS parameter
only.
If you want to both specify a new ACDS and update it with the contents of an SCDS, enter
the SETSMS command with both the ACDS and SCDS parameters specified.
The ACTIVATE command, which runs from the ISMF CDS application, is equivalent to the
SETSMS operator command with the SCDS keyword specified.
If you use RACF, you can enable storage administrators to activate SMS configurations from
ISMF by defining the facility STGADMIN.IGD.ACTIVATE.CONFIGURATION and issuing
permit commands for each storage administrator.
