Hi All,

Please help me to convert ISAM files to VSAM files.

Thanks in advance

Hello abhiman and welcome to the forums,

What sort of help are you looking for?

Unless there are to be system changes at the same time, i believe the original data structures (copybooks) will be usable. You would only need to define the new vsam files and load the data.

If you post an example of what you have and where there are questions/problems, someone should have a suggestion.

Hi Dick,

Thank you for your inputs.

Atually i am having some ISAM files(like Cluster in VSAM) which i need to convert into VSAM files. Also some JOBS are there which are using these ISAM files.

So do i need to define only VSAM files?

Also which type of VSAM file do i need to define? (KSDS,ESDS or RRDS)

Also if anyone knows any Book for ISAM, please suggest me that.


Thanking you in advance,

Hello,

So do i need to define only VSAM files?

That would depend on the requirement and the answer must come from within your organization. I would expect the goal was to move off ISAM, but that direction should come from your management.

Also which type of VSAM file do i need to define? (KSDS,ESDS or RRDS)

Start with KSDS and if some other requirement is determined, then go for others.

Also if anyone knows any Book for ISAM, please suggest me that.

Long ago, i believe Doug Lowe wrote some books that included ISAM. You might search on the web to see if any might still be found.
