Is there a CA Librarian utility or another way to identify all CA Librarian Master files on a system?
Unfortunately, there is no CA Librarian utility to read the system catalogs and identify CA Librarian Master files.
However, you can run a CA Librarian Master Index Statistical report against a file and see if it is a Master file --
//INDEX EXEC PGM=AFOLIBR,PARM='NRJS,NJTA'
//SYSPRINT DD SYSOUT=*
//INDEX DD SYSOUT=*
//MASTER DD DISP=SHR,DSN=LIBR.V44.LVL1.PRODMAST
//OSJOB DD DUMMY
//SYSIN DD *
If the file is not a CA Librarian Master file, it will return a LIBR0003E error --
LIBR0003E MASTER FILE MASTER IS INVALID OR HAS NOT BEEN INITIALIZED.
Traditional Librarian Master files can be BDAM or VSAM organization; Wide Record Master files are PDS or PDS/E organization, so we cannot eliminate any files based on organization.
