Rich,--
Can you supply more details for your environment, both system and
backup device used.
Are the PF you reorged journaled? Your journal receivers may be large
and you may be saving them, would explain the longer backup times.

Subject: Re: Backups taking longer after reorg
All,
I did a simple dspfd to an outfile and looked at the percentage
of deleted records to total. I did the reorg on those that had more
than 10% deleted. All of the rebuilding of indexes is done but my
backup time is still 30 minutes longer than it had been. I am NOT
using the save while active stragegy.
I am doing an IPL tomorrow. Don't know what else to do. Any
help is much appreciated.

Are you doing reorg or reorg while active?
We run a similar process using reorg while active.
Reorg will be quicker, but requires exclusive use of the files, and
I believe will cause the index rebuilds.
Reorg while active will be longer, users can remain on, index
rebuilds are less, done concurrently.

Subject: Backups taking longer after reorg
All,
First, let me wish everyone a happy new year. I hope that each
of you is blessed this year with good health and prosperity. Now to
my issue
- I wrote a program that scans through libraries and reorgs files
that have many deleted records. Sounds reasonable
enough.....However, since running this program, my backups are
running much longer. Why would this be? Is there something that I
can do to get the time needed to save these libraries back to a reasonable timeframe?
I have considered saving the libs to a save file and making the
system available while backing the save files up to tape (which I'm
assuming would be faster given the I/o rate of disk vs. tape). But
I'm perplexed as to why the reorg would add time to my backup.
Any thoughts/suggestions are much appreciated.
Sincerely,
Richard Reeve
