Feedback requested on poor system manager's defragmentation DCL procedure

Robert_Boyd — Fri, 17 Feb 2006 07:46:16 GMT

After downloading Kostas Gavrieldis' VMS_CHECK and running it on 2 or 3 clusters, I noticed that here and there would be a disk that had terrible fragmentation situations.

Not having a license for defragmentation products on these systems (and not much likelyhood of getting approval to buy any) I decided to see what I could do with DFG reporting and DFU defragmentation.

After playing with them by hand it became obvious that a DCL procedure would be relatively easy to put together.

I wound up including a fragment of code from VMS_CHECK (with permission from Kostas) so that anyone with VMS_CHECK could run it even if they didn't have access to the DFG install kit.

I'm interested in getting feedback about this approach to spot defragmenting, and any comments about the procedure. Karl Rohwedder already provided some fixes for pre-V7.3-2 systems and VAXes.

The procedure is viewable at

There's an odd bit in the comments at the beginning explaining the parameters -- just replace "<" with "<" and ">" with ">".

I hope this is not viewed as advertisment and been removed :-)

Ha! Kalle I was thinking the same thing when I was posting it!
