Did the slow down occur after the extra disks were installed in your EMC
array? Is the space in the array using mirroring or RADI-5? Mirroring will
give better write performance. Also, how are the disks laid out, number of
channels into the array, number of busses on the 997? Also how are the
ldevs laid out in the EMC itself. Are you using both halves of the mirror
for the data group? When we had our 997/400 it had about 12GB of memory
and six channels into the EMC array and only 2 channels on each bus. We
would get 1200 to 1800 claims per hour through BCP0100 during the morning
hours, falling off to 800 - 1000 when we ran during the day. We spent a
lot of time placing the various volume sets (we have more than a dozen)
into the array to avoid as much contention with the system volume set and
the data volume set as possible.
Currently our data group is about 484 million sectors

Re: [HP3000-L] system response time
Nothing much, added some disk, installed a bigger EMC unit.
All of the details are below 88%, most of the masters are under 80%.
All disk sits on the EMC.
Our databases sit on their own volume set (35 volumes), all other data
reside on another volume set.
We were getting as much as 800 per hour.
I think our biggest hit is during the day when the on-line processing is
contending with the batch. I'm wondering if there is some tweak within my
workgroups that might help. I'm not confident in my configuration of
this,
and haven't made many changes since the last sys admin left.

What has changed since earlier this year?
Have we checked the capacity of the databases, I think the big one is
called Healthdb or something like that.
How are the disk drives and volumesets installed?
How many transactions per hour were you doing earlier?

Subject: [HP3000-L] system response time
Looking for help with some system response time problems.
We are running Amisys on a 997/400 with around 4.8 gig of memory. Our
health database is 302 million sectors (majority of it is obviously
service). We have been processing between 300 - 600 claims per hour
during
our nightly batch window, but had been getting more earlier in the year.
Because the load exceeds the batch window (everyday) we end up
processing
during the day and use weekends to get caught up. Our online users are
killing us with complaints, and it would be nice to ease their pain. Is
there anyone out there that is in a similar environment that wouldn't
mind
sharing their secrets??
thanks
