ZFile and multi volume datasets

MichaelLueghausen · Post by **MichaelLueghausen** » Tue May 16, 2006 3:45 am

I need to open new (create) multi volume datasets using ZFILE.
It looks to me that this is not possible because there is no appropriate function/support in the underlying C/C++ API. Any suggestions to solve this problem are welcome

Thanks,
Michael

There might be a better way to do this, but whenever I run into something I want to do that JZOS can't help me with (and I can't easily write a JNI application to do), I just submit an MVS job to take care of it. There's a free API available on IBM's site that allows you to submit MVS jobs to the internal reader from Java:

You're right; sometimes JCL works best.

But you might be able to use the ZUtil.bpxwdyn() interface to BPXWDYN to do fancy allocations.

BTW: there is a new release of JZOS coming out any minute (version 1.2.4) which fixes BPXWDYN. (It was broken in -some- environments)
