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) ...

OMVS Shell Logging to SYSLOGD

IBM should provide the ability to log messages to the active OMVS/USS syslogd. Currently logger, which is standard in UNIX for writing messages to syslogd, does not have this ability in z/OS but writes messages to the z/OS SYSLOG without an option...

CHECK(IBMUSS,USS_PARMLIB_MOUNTS) make MTAB updatable.

IBM Healthchecks are very good to follow, to avoid an outage. We use them a lot! But if a mount statement of a ZFS data set is wrongly defined in BPXPRMxx. The Healthcheck (IBMUSS,USS_PARMLIB_MOUNTS) complains with an exception. "ZFS NOT MOUNTED. ...

MMAP function under z/OS USS should be able to use 64bit address space.

We have a proof of concept to run an off-the-shelf name indexer product under z/OS USS. This product is a native 64-bit Java 8 application that uses the Lucene indexer. The product functions under USS for small indexes. However, the call to mmap i...

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 ...

Customer running an app that hit an internal limit (JRSMCMaxCntSeg 65535 decimal)) creating shared mutex and shared convars. Discussions with the customer indicate that there is a need to support one million of these type of structures. This will ...

BPXN004I msg should be "E"

BPXN004I error condition is much more than an information msg and this condition can cause sysplex wide uss issues

Automount and RACF FSACCESS

When we use automount, where the policy creates a new zfs for a userid, in conjunction with RACF FSACCESS, "phantom" directories are created. It would seem more sensible that automount honours FSACCESS before the dataset is created.

Simplified MNTE_SYSLIST syntax as part of z/OS UNIX REXX mount command

Currently, if a user would like to include MNTE_SYSLIST as a parm in his USS REXX mount command implementation, the user must code the MNTE_SYSLIST as though they are writing assembler code using the mapping described in BPXYMNTE: MNTENTSYSLISTNUM...
