Thanks LJ for your input.
FYI - We've tried the sync but have not found it reliable. Part of the problem with the sync is that is does not easily identify to the admin the progress of the snyc and when it has completed; and don't tell me to scan the midtier or tomcat logs :-) I'll live in hope that this process is re-designed and improved in the near future.

Because of this translation process, they either need to store a copy in a translated cache, or pull it 'on the fly'....on the fly is how it used to work, and we all complained about the speed...so they now allow for caching...but the more 'client side' objects you have, the larger the cache needs to be, and the longer it takes to cache. There are only a few things that can be done (that I can see at least) to correct this 1 - Make fewer things needing to be cached. This involves simplifying the user interface so that there aren't thousands of fields on every form, less forms, less fields, less active links 2 - Make the translation easier to perform. This would require storing the information in a different way in the DB so it required less 'change', or making the translation process more efficient so that it can do it quicker with less resources There was a 'Sync Server' option added some releases ago (don't remember what version), but this process apparently goes through and compares the cache with the server, and only modifies the structures that have been modified. This in theory would prevent the need to rebuild the entire cache, just the modified pieces, thus making #2 above true...but I've heard people having problems with it, so I don't know how well that's working I personally feel that #1 is the best option...with less objects to synchronize, less time is needed...and we all know (others better than myself) how complex ITSM is.

There's got to be a better design that would not need to utilize this form of caching in the first palace. We go through this nightmare everytime we deploy - it's a headache. We have 2 active mid tier servers (Windows/Tomcat) active to users. So everytime we deploy we have to disable one from the load balancer, flush cache and then wait 1 hour for it to complete the rebuild. So that's at least 2 hours of my life down the drain everytime we deploy. I already have to deploy after hours, so having to wait for the caching to complete really gets under my skin. We've found we can't leave a mid tier server active to users during the rebuild due to slowness as a result of CPU consumption for the rebuild. I hate to think what this would be like if I had more than 2 active web servers. I've seen plenty of other enterprise web apps where all you have to do is drop in the applicable objects (jsp ,jar, aspx, xml, html etc..) then you're done. That's it...why can't BMC make this process cleaner and more efficient? In my mind it would be great if the objects in Dev Studio represented as objects on the web layer that could be pushed by themselves or all as a whole. E.g. if I was making a change to HPD:Helpdesk and added an active link, then the objects at the web layer for HPD:Helpdesk and the new active link would be pushed - that's it done.
