Printing a Catalog or VVDS

You can print the contents of a BCS or VVDS with the PRINT command, but the only circumstance where it might be useful is when you need to determine which catalogs are connected to a VVDS. This might be necessary to determine which BCSs to specify in a DIAGNOSE command, or when you are recovering a volume.

The names of the first 36 BCSs connected to a VVDS are in the first record of the VVDS. If you print this record using the DUMP format, you can read the names of the BCSs in the character format portion of the dump.

The following step can be used to print the first record of a VVDS. Because VVDSs are not normally found by catalog searches, use the INFILE parameter to specify a DD statement defining the VVDS.

 //PRNTVVDS EXEC PGM=IDCAMS
 //SYSPRINT DD SYSOUT=A
 //VVDS     DD DSN=SYS1.VVDS.VSPOOL1,DISP=SHR,
 //            UNIT=SYSDA,VOL=SER=SPOOL1,AMP=AMORG
 //SYSIN    DD *
       PRINT INFILE(VVDS) COUNT(1)

A catalog or VVDS can also be printed using DFSMSdss.
