Thanks Lj. So during the rebuilding process users are unable to use the web interface?

Regarding the server cache, that's accessed at http://<webserver>:<port>/arsys/shared/config/config.jsp<http://%3cwebserver%3e:%3cport%3e/arsys/shared/config/config.jsp> You provide the password needed, and then go to Cache, and press the 'Flush Cache' button....now...for the impact. Depending on your version, load, etc...the impact can actually be rather severe. Without a cache, the server needs to retrieve everything from the server, and re-compile jsp pages before it can present the page to the user. As you are aware, there are 10's of thousands of active links, and thousands of forms associated with the ITSM app, so the re-cache process, depending on hardware can sometimes take in upwards of an hour or more...so it's something that should likely be done 'after hours' if at all possible....but I sometimes do it on my server in the middle of the day depending on the impact that it not being flushed has on the user base...so it's really a judgement call.

How do I flush the mid-tier cache and what affect does that have on the users? Also, by clearing the user cache are you referring to delete temp internet files? Thanks again!

I would start by flushing the Mid-Tier cache, and then the user cache if they continue experiencing issues.

Using the thick client to access this works fine however. Any ideas on why this would be happening?
