Problem with utility dataset deletion and data control: IBM Y2K Report

greenspun.com : LUSENET : Grassroots Information Coordination Center (GICC) : One Thread

Non-SMS managed utility datasets may be incorrectly deleted; FREEVOL may cause loss of control data.

Will someone please translate and expand the ramifications of this story. Thanks Carl

DFSMShsm: Non-SMS managed utility datasets may be incorrectly deleted; FREEVOL may cause loss of control data

SUBJECT: DFSMShsm: Non-SMS managed utility datasets may be incorrectly deleted; FREEVOL may cause loss of control data

. When utility datasets (a subset of temporary datasets) are defined as non-SMS managed, the following DFSMShsm functions: Primary Space Management, Interval Migration and Incremental Backup, may incorrectly delete these datasets. Please review APAR OW42637 to see the complete definition of utility datasets as well as additional information for determining your exposure.

In a multiple host environment, running the above indicated DFSMShsm functions on one system may delete a utility dataset in use on another system, causing that job to ABEND. This applies to any environment where there is more than one system image that can access the same DASD volume and is not limited to SYSPLEX environments.

2. The FREEVOL function is used to move the DFSMShsm data on a DASD volume to a new volume. FREEVOL processing deletes DFSMShsm control information for volume backups and dumps, rather than moving the data to another ML1 volume. RESOLUTION: A fix for APAR OW42637 is now available which resolves both problems.

The fix is available on FTP site

ftp://testcase.boulder.ibm.com/mvs/fromibm/. There are four different versions available, depending on system level:

I'll pass your question on to my dad's wife, who works in this department at the Boulder facility.

Maui's doing well...Out in the middle of the Pacific we have no major problems..just small stuff so far. And the whales are back. Have you ever see a humpback whale up close and personal? Ok, I'll go back to work now.
