Rebuild While Open

Greetings MH, welcome to the forum.

If you haven't already done so, please have a look at the new CSL support page at: https://support.emc.com/products/CatalogSolutions.aspx

We have a great deal of info there. I will hunt down one of the Catalog Solution folks for the more specific gotchas, hints and tips. However, since you're already at PTF EC90004, - the most current, you're in good shape.

Best regards,

I did do some checking for you, before our esteemed CSL types chime in.

I found a knowledgebase entry emc138377
If a USER catalog is connected to multiple MASTER catalogs, they must be connected to the MASTER of the system you are running on and they must be specified in the INCMAST= parameters.



See the Catalog Solution 9.0 documentation entitled 'Catalog Solution 9_0 Documentation Addendum for PTF EC90001.pdf'. This is available through PowerLink.

This addendum is intended for all users of Catalog Solutions for z/OS, PTF EC90001. It includes updates for the User Guide, the Scenarios Guide, and the Message and Code Guide. It contains a replacement for the REBUILD WHILEOPEN (RWO) chapter in the GA user guide with all the new keywords.

Run the RWO with the trace keyword. This adds a few lines to the output, but they're very informative and it's useful information whether it's only for historical comparison, benchmark, or troubleshooting.

Also, don't cancel RWO as a general rule. If you consider what it's doing, and how it's going about doing it, cancelling of an RWO process ought to be discussed with a CSL pro first.

Here is additional information:

If all you're trying to do is reorg the catalog without any changes to it, you may want to do a REBUILD WHILEOPEN In Place with the following syntax:

REBUILD WHILEOPEN,TRACE,
INCCAT=your.user.catalog,
BACKUPHLQ=alias,
BACKUPSPACE=(x,x,CYLS)

Space allocation should be at least as large as the catalog being reorg.

If you want to move the catalog or reallocate it with more space, then a REBUILD WHILEOPEN REALLOCATE is the way to go. A syntax sample:
REBUILD WHILEOPEN,TRACE,
REALLOC,
INCCAT=your.user.catalog,
BACKUPHLQ=alias,
BACKUPSPACE=(x,x,CYLS)
NEWCATVOL=volser
NEWCATSPACE=(x,x,CYLS),
INCMAST=alternate.master1,
INCMAST=alternate.master2

BACKUPSPACE: Space allocation should be at least as large as the catalog being reorg¿d.

NEWCATSPACE: Space allocation should be at least as large as the catalog being reorg¿d.

Volser = new volume (if catalog is to be moved)
INCMAST: specify ALL the master catalogs that the user catalog is connected to

However, please be aware of IBM APAR OA23588 when using REBUILD WHILEOPEN REALLOCATE.

Hope this helps
