Wondered if anyone has seen this before in an XRC config? This is the RMF
display for the primary DASD for looking at delays for 1 job. I must admit,
I thought we only had 32 PAVs on this entire SSID - I'm checking now.
Is this a record?

Job that normally takes about 15 minutes ran for over 2 hours and RMF shows
the delays down to 1 volume.
The job started with 1 PAV and immediately rose by 2 per 100 sec interval
until it hit 15. During this period it was showing above 90% delay for this
device.
I'm about to cross check with any XRC delays.........any other ideas.
------------------------------------------<unsnip>----------------------------------------
I'm sure that your application is doing a great deal of writing to the
delayed volume. We also experienced a delay-related problem in XRC
performance. The solution we eventually implemented was to upgrade the
"catching" device; delays were caused by "write penalties" in the
catching device. The local cache in our 2105-f20 was filling up so fast
that many channel paths were being disabled in an attempt to "pace" the
writing activity. The remote device, another 2105-f20, just couldn't
keep up. In our case, the Data Mover was at the remote site and the
links were a pair of dedicated T3 connections.
