Please let me know the way by which we can know the count of the existing versions under a Particular GDG Base.

Hello,

Try tso 3.4. When you put in the base dsn, the system will show you all of the cataloged versions.

If you're looking for anything else, let us know.

ihatesugar,

Use LISTCAT ALL option in IDCMAS. The NONVSAM value at the end of SYSPRINT (in the spool) indicates the number of existing generations (i.e., gives count like 2 or 6 etc...).

Let us know, if you need more help in this regard.

Just a little intrigued as to why you need to know the number of existing versions. Would you care to elaborate a little ?

Hi expat,

I was actually trying to figure out a way to implement FIFO... then realised it wont work by having the count and using it to pick up the oldest version of GDG relatively

Hello,

No, but you could use the fully qualified dsn and process FIFO. . . When you run the LISTCAT you can see all of the versions fully qualified.
