Application server load...

OVSD 4.5, SP 17
Just want to get a feel for what everyone is running out there for server load. We have 3 application servers running normally with about 80 - 100 users each. The JVM is set to use 1.5GB.

We're experiencing out of memory errors in the log and I'm interested to see if others are running the same load.

Thanks,
Ryan

Re: Application server load...

We're running OVSD 5.1 SP3 with about the same load. About 100 to 120 people per server on two application servers and a dedicated Service Pages server. If our JVM isn't killing our system, then its OVSD dropping brand new types of errors every month.

Been running almost a year and a half with outages 2 - 4 times per week.

Re: Application server load...

Hi Ryan

What memory is available on these 3 servers? are they Windows servers or HPUX?
what is your configuration for Garbage collection? can you post your installservice.bat?

We run SD4.5 SP18, we have 2 application servers running around 40 users each and we have had no performance issues, this has been in place for 14months with 0 outages!
JVM is set to use 1GB memory.

You may want to try installing an extra instance of a service on each service and see if this improves your performance.
For more info about this see Chapter 7 of the Admin guide

Hope this helps

Re: Application server load...

We are running HPUX servers with 6GB each. The JVM is configured to use it's maximum of 1.5GB.

Currently we've been experiencing issues about once a week.

Current execution string:
/opt/java1.4/bin/PA_RISC2.0/java -XX:MaxNewSize=157M -XX:NewSize=157M -Xms628M -Xmx1512M -cp lib/classloader.jar com.hp.startup.Bootstrap com.hp.ifc.bus.AppServer

Ryan

the info from your installservice.bat seems ok.
Maybe you want to think about installing a second service desk service on each server.
therefore with your 3 app servers you could have 6 instances of the SD application.
you could set each service to use 1 or 1.5gb Java memory.
Im sure this would resolve your out of memory issues.

look at chapter 7 of the admin guide for instructions

Just another point, from your profile I can see that you hardly ever allocate points to other members for their help. Please assign points to members that give you useful answers.

for more info:-
How Do I Assign Points?

Only the question author can assign points to a given response. If you submit a question or new topic and another member replies to it, you will see a dropdown menu of points next to the reply (you must be logged in to see the menu). Select the point value and then click the "submit points" button. Note that you can rate multiple replies and submit them at one time.

Re: Application server load...

Ryan,

You could try launching the service desk client with the benchmarking turned on. this will give you information about speed of database, server, network and client

from a command line run:-

:\Program Files\Hewlett-Packard\OpenView\service desk 4.5\client\bin>sd_client /BENCHMARK
