We are planning to create a VSAM KSDS file of length greater than 32K. Is there any way to take the backup of this this VSAM file into Sequential file on DASD or tape.

I tried 3.2 option but errored with out of range
I tried SORT, IDCAMS and other utility but was not able to achieve this.

Any thoughts please...

Thanks,
lal

Why do you believe you need records this large? Sounds like improper design. . .

Have you tried ADRDSSU? Have you talked with your storage management people to learn what additional tools might be available on your system?

Sometimes these length records appear in scheduling software such as OPC. (TWS).

My usual approach is to do a VSAM to VSAM copy and then back up the copy of the VSAM file. As suggested above, ADRDSSU (DFdss) and talk to your storage people.

Thanks for the reply.
Our currently master file is VSAM-KSDS which is about 25K length due to the addition of other customer information the length of proposed file is going past 32K limit.

That's the reason I wanted to know if it was feasible to take the backup of the newly proposed master VSAM file using any utilities.

We do have ADRDSSU, so do you think that I can use this utility to take the backup of this big VSAM file.

Thanks,
lal

After the backup is created, make sure it can be reloaded into a test vsam file and used. It is a rather horrible discovery to learn that the backups created are not usable. . .

Until a backup has been reloaded and the data successfully used, all that exists is some media with questionable content. . .

Thanks everyone for your input.

Well, I used ADRDSSU's DUMP command to store the VSAM file and used the RESTORE command to restore the VSAM dataset back. It is working perfectly...

Thanks,
