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. ...

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 needs to map up to one million shared mutex/shared condvar per shared memory segment under z/OS Unix.

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 ...

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...

Z/OS Unix OCOPY

Update OCOPY to correct abend S213-15 (IEC143I) if DSNTYPE=LARGE and SMS BLOCKTOKENSIZE is REQUIREd.

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...

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.

ID Token support in pthread_security_np et al

Please add RACF/SAF ID token support to pthread_security_np and pthread_security_applid_np C library functions (and underlying BPXnTLS etc) so that an ID token can be passed as the "identity" parameter to these functions. Oh and please do Java too...

RACF Profile BPX.SAFFASTPATH

Make BPX.SAFFASTPATH more granular (e.g., add userids and access) or add another profile with a userid and access authority to USS resources. Access to UNIX services and resources (e.g. IPC queues) requires many, many SAF Router (IRRSXT00) calls f...
