USS Kernel to lift MVS Wait restriction when threads need to be accessed by LE

LE CEEDUMPs fail to collect data from paused threads in a multi-threaded environment due to the use of PAUSE/RELEASE and are in an MVS Wait. We're requesting the USS Kernel remove this restriction (similar to APAR OA44116 for KernWait) so threads ...

BUFNO calculation for Extended format sequential datasets

BUFNO are calculated according to the following formula: n—Extended format but not compressed format and not LBI (n = 2 × blocks per track × number of stripes)1—Compressed format data set, PDSE, SYSIN, SYSOUT, SUBSYS, UNIX files2—Block size > =...

A full PDSE dataset should be able to delete members without needing additional DASD space

We currently have a large SMP/E SMPPTS PDSE dataset which is full on a volume with only 5 available cylinders. Attempts to delete a member from the PDSE result in a E37-04 abend because the system is trying to get an additional extent. The dataset...

DIRMAINT needs to do additional RACF commands when creating a new virtual machine

DIRMAINT needs to do additional RACF commands when creating a new virtual machine. This is useful in a RACF environment using sitewide SECLABELs for mandatory access control. The commands affected would be DIRM ADD. An additional operand of SECLAB...

Enhance message IFA016I with the root cause

There are numerous reasons a SMF dump program IFASMFDP USER exit might not be available, but the IFA016I message is a catch-all / generic message that does not provide any useful information (outside of an abend issue) which the user can use to di...

HSM detaches lower level data mover tasks and produces hundreths of BPXP018I THREAD tttttt, IN PROCESS ppppp ENDED WITHOUT BEING UNDUBBED WITH COMPLETION CODE 0033E000 AND REASON CODE 00000000

During file backup we get hundreths of BPXP018I with COMPLETION CODE 0033E000. When this is the way how HSM works it would be great to change it and avoid all this messages as the backup function in HSM ends correctly. Putting the BPX018I into MPF...

ISPF does not record the alias name in SMF14ALIAS when accessing datasets via their alias

When browsing or editing datasets under ISPF, if the dataset is accessed through an alias, ISPF uses the real name to access it, rather than the alias. Other allocation services, such as JCL, use the alias. In z/OS 2.1, a new field in the SMF type...

Consistent Read from Secondary - decision making in response to poor performance/hardware health changes

Our current understanding is that to exploit the DS8K's consistent read from secondary function, IOS currently sends some queries out at Hyperswap enable time in order to determine at the LCU boundary whether reads should be directed to the PPRC p...
