To dynamically install a new MVS™ subsystem, load the initialization module from an existing linklisted library. To dynamically install the CICS® VT SSI, perform the following steps:
SETPROG LPA,ADD,DSNAME=VID.SVIDLPA,MASK=VID*
SETSSI ADD,SUB=VIDS,I=VIDSSINT
The CICS VT SSI is now ready to use. Note that any valid name can be chosen for the subsystem, but it is recommended that you use VIDS.
