Re: Re:Has Reclaim Storage becoming outdated?

A full reclaim is not recommended as part of "normal maintenance" and
shouldn't be run unless directed by support. See techdoc below for the
guidance if people don't believe you. Many customers are still doing this
monthly or quarterly or annually just because they always have. Presenting
this doc allows breaking of that cycle and saving of valuable technical
personnel's time!

Thanx everyone for your responses regarding RCLSTG.

IBM SupportLine has informed me that a RCLSTG *ALL should only be run when
requested by IBM Support personnel.

Recovery after a crash is much easier now since the RCLSTG command has
been changed to allow pieces of it to run separately (for example *DBXREF).

This change and the use of "system-managed system access path recovery"
makes it possible to recover from a crash within minutes instead of days !

For example, after the recent crash of our system, none of these large
access paths had to be rebuilt because they were protected with
"system-managed system access path recovery":

My original premise that RCLSTG has become outdated was misguided. It has
actually evolved into an even better tool for recovery of the system in the
event of a crash.
