Background: We want to use Optools/SystemAutomation to quickly obtain an overview of all datasets allocations that trigger this message, even though the job ends with RC=00. IGD17162I RETURN CODE (12) REASON CODE (5F01083F) RECEIVED FROM COMPRESSI...

GDS_RECLAIM should delete/define the GDS versus reusing the same create date

Currently, when you turn on GDS_RECLAIM the system will reuse an existing GDS if it is in DEFERRED status. This is a great idea except for the fact that the process keeps the original create date. In one instance we had GDS' that were created in F...

Enhance SMS message IGD17279I to better describe file allocation error - the diagnostic code in the message (041A041D) is not useful.

Hello, we recently had an incident with non-VSAM allocation space problems on EAV volumes due to the Dataclass EATTR defaulting to 'blank'. We came across the following message and required IBM support to provide an explanation: IGD17279I 411 VOLU...

Enhance DFSMS to check for assignment of DATACLASS values for the SCDS, ACDS, & COMMDS

This will inform administrators prior to an activation that a configuration conflict exist which may cause activation to go into allocation, effectively preventing activation from proceeding. Worse case could be a difficult to recover CDS file.

add the substr function into ACS routines to simply SMS management for complex environment

I have been working with a customer who wants to obtain the subsystem ID for more generic filtlists and storage group assignments. Something like filtlist XXXSAP INCLUDE(DSN%%%U.**, 'ICF.DRPLEX.%%%SAP') EXCLUDE(DSN%%%%%.ARCHLOG1.**, DSN%%%%%.ARCHL...

DFSMS, SREAD OVER VOLUMES depending upon volume-status and free-space

'Spread over volumes' allocated always on the volumes at the beginning of a storagegroup, regardless of volume-status : QUINEW,ENABLE and free-space. If it supported the behavior of primary allocation over multiple volumes no longer differs from o...

ACS Read only variable required for RECFM

We are converting our sequential data to extended format in preparation for pervasive encryption. We use the zbna software to identify files unsuitable for EF, due to utilising EXCP. We have identified a lot of files with a RECFM of FS (mostly SAS...

Use of a filtlist in the exclude statement

We would like to be able to use a filltlist in the exclude statement of another filllist. Often we have a long list of datasets that are allocated with custom constructs. So that the general filtlist does not unintentionally take effect, we also e...
