DFSMS VSAM/RLS

Showing 17

Enhanced monitoring of VSAM RLS activity using z/OSMF interface

Whenever there is a need to check SMSVSAM health for contention, locks response times and record queues one has to rely upon console commands usually routed to all the LPARs that run RLS workload in order to have a big picture of what is going on....

Health Checker - VSAMRLS_QUIESCE_STATUS check

Whenever there is a situation that causes VSAMRLS_QUIESCE_STATUS to alert ( by reaching the predefined threshold for the quiesce status ) this check generates a list of the CICS regions accessible only if you go inside the check - that means you h...

DFSMStvs have a hard upper limit set in PARMLIB that cannot be overridden by JCL

Currently the TVSAMCOM in PARMLIB can be overridden by including TVSAMCOM=(n,n) on the JCL EXEC statement. in our case, we've had a couple of instances where an application did not take the default set in PARMLIB and flooded the CF and SMSVSAM wit...

provide Display SHCDS command with results that go to SYSLOG for automation.

SHCDS commands work both in batch and in the TSO/E foreground, but the output isn't available in SYSLOG. Automation around SMSVSAM/RLS issues would be easier if we could drive standard z/os commands such as /D SHCDS xxx and have output go to SYSLOG.

Include the dataset name in the IGW859I message text

The Itau bank and IBM has a project to activate the DFSMStvs product to run on the GRBE (Itaú OLTP application) to support the online workload.So, it is very important to us to have an improvement for the message IGW859I, today this message doesn'...

Allow reuse for VSAM file opened in RLS mode

To be able to use REPRO with the REUSE option against a VSAM file that is opened in RLS mode
about 3 years ago in z/OS / DFSMS VSAM/RLS 1 Planned for future release

Request to create a new RLS command to show the name of the data sets that are allocated inside a data cache structure.

The Itau bank opened the PMR: 28951,228,631 because we didn't find a way to know the VSAM RLS data sets that were allocated inside a data cache structure. During the pmr the only way to find the name of those data sets was to check this informatio...

Merge Library SYS1.SDWWDLPA into SYS1.LPALIB

If module DWW1VS00 (alias DWW1SCSR) is not present on LPA at IPL time we will get an abend X'0C4'. That is not an obvious problem to be solved, because the message does not indicate a library missing. The Library SYS1.SDWWDLPA is critical to IPL t...

VSAM RLS Lock Information

Today VSAM RLS relies on the LISTSUBSYS(ALL) and LISTSTAT IDCAMS share control dataset commands as a way to list the CICS regions which hold locks in RLS files and to provide statistics of usage of a certain sphere. There is no information about w...

Provide a warning threshold or limit for the number of record locks

A looping application in a development environment can request an excessive number of record locks. This can result in excessive cells in use for the IGWLNHRB Storage Pools and a storage shortage which can terminat and restart the SMSVSAM address ...
