TS UI slow performance

suj

One of our installations is still on TS 5.5.2 and while I wait for the upgrade to happen early next year I know this is the only place to get any answers to my questions on 5.x.

Env: 5.5.2 Build 23679 Interwoven 20030813/Solaris

The TS UI has become extremely slow and we tried system reboots, resets etc. to no avail to fix this issue. The UI is extremely slow right from
the login page. All the services are up and running and iwserver.log and iwtrace.log does not have any errors. The CPU load is normal, its idle most
of the time.


Here are some of the anomalies we noticed.


1) The iwevd.log has the following error.

**ERROR**: SummaryEventChannel.read unexpected exception
java.io.IOException: Connection reset by peer
at java.io.RandomAccessFile.read(Native Method)
at java.io.RandomAccessFile.readLine(RandomAccessFile.java:719)

2) sevletd.log has the following errors on startup of servlet engine. I noticed that the files mentioned below are not there in the specified
locations and when I compared to our dev env which does not have any problem, these files dont exist there also, but I dont see any errors though.

Can anyone give some pointers what could be the issue here? Will reinstalling webapps help?

TIA

Upgrade!

For your performance issue, I feel, you should first check on the below -

1. Check your CPU Consumption - Note it
2. Check if there are any stale workflows jobs lying in the queue. End these jobs.
3. Check your CPU Consumption now
4. IF 2 does not help, determine if you have changed any thing in your environment since TS was working fine, Server OS, Client OS, Client Browser, Service packs etc.
5. Try an iwreset -a


Reinstalling webapps would be the last choice. Also, please note, 552 is no more supported by IWOV and the above steps are obvious for a performance issue. No claims from my end. You are upto your own
