In the SYSVIEW for DB2 VTAM User Interface address space JCL there are three possible values for the PARM.
1) PARM USING IDB2USER AS THE VTAM APPLID WITH NO
2) PARM USING IDB2APPL AS THE VTAM APPLID WITH
SYSVIEW INTERFACE ENABLED USING PC TASK USING
SUBSYSTEM ID OF PC63:
3) PARM USING IDB2APPL AS THE VTAM APPLID WITH
SYSVIEW INTERFACE ENABLED USING DEFAULT PC TASK:
If you work with the CA SYSVIEW for z/OS and CA SYSVIEW for DB2 interface you have to work with PARM='IDB2APPL,IDB2,DBGI' to specify the default PC Task if the PC Task is not started for Release 19.0, as in Example 3).
Example 2) is when the PC Task is started with a Subsystem Id other than the default value DBGI.
