Improvements to the ability to ascertain whether zFS filesystems are in migration

There is currently no way to check whether filesystems are in mirroring complete status but waiting for a swap operation to complete other than using the bpxwmigf command. I'd also like a new reason code issued when the user attempts to manually m...

Citi requests WJSIPUSE be a formally supported product

Citi has had experience with WJSIPUSE. They asked me if it, or an equivalent, can be formally supported by IBM. I am submitting the request on their behalf.

USS_PARMLIB_MOUNTS Health Check Refresh After IPL

During a recent IPL a typo in the BPXPRMxx member had the incorrect name for a zFS file system. As a result, the mount failed with error message BPXF002I: BPXF002I FILE SYSTEM OMVS.ASYS.ORESB1.COBOL42 WAS 674 NOT MOUNTED. RETURN CODE = 00000081, R...

USS command bpxwmigf need to force a swap

I am using bpxwmigf uss command to help to migrate from HFS to ZFS, and also from a ZFS to another (extended) ZFS. It is very useful and reliable. But sometimes it fails to swap to the new ZFS due to message : status.......: swap deferred at 08:31...

Issue WTO about the ROOT (sysplex root) mount after processing BPXPRMxx

As we had a failure to mount the sysplex root correctly (see PMR), it would be very useful to have an indication after processing the BPXPRMxx (IPL) how the root filesystem was mounted (RO or RDWR). If the mount was not made as wanted (see PMR) ma...

Ignore invalid entries in the AUTOMOUNT policy and activate the policy with valid entries.

We've had a directory in our automount policy that did not actually exist for some time and it has not had any ill effects from IPL to IPL of lpars in the sysplex. This past weekend we had a sysplex outage and the unallocated directory prevented t...

SMF92 record remount in correct mode

The product only writes out the remount SMF record during the unmount portion and does not write another record after it is mounted again. This means that the mode in the record does not necessarily reflect the correct mode in effect after the rem...

USS panel BPXWP20 "Work with Mounted File Systems" does not show the mount hierarchies.

It would be nice to see the hierarchy of mount points on the BPXWP20. An intuitive/topological presentation of file systems would be very helpful. The practical purpose would be unmounting an FS that has child mount points to other FS'es. For exam...

Provide a SETOMVS SYNTAXCHECK equivalent via a batch job.

Request a batch utility which would allow you to check BPXPRMxx syntax via a DD for input and route the output to a DD. The benefits would be: (1) Allow any location for input (vs. current SETOMVS SYNTAXCHECK which must come from PARMLIB) and (2) ...

ZFS save cpu. Provide option to stop SMF file activity, and eliminate getmain/free main for every open/close SMF record

When I was looking into Java was so slow on z/OS compared to Ubuntu, I noticed there was an SMF call for every file open ( and close) , and a getmain/freemain as well. To start z/OSMF took over 600 seconds of CPU! This needs to come down to about ...
