XenApp 6.5 Data Collector & Database - What sort of maintenence should I be doing on these? The App center is running considerably slower over time.

After first creating our XenApp 6.5 farm, The App Center was quite quick to load. In particular when creating/editing Citrix Policies. However over time it is running slower & slower. Eg any type of Citrix Policy change can take anywhere between 40-60 seconds to complete & refresh the console. It's not the end of the world, but as you can imagine when making large scale changes, it becomes a very long process.

Since the farm went live (about 12 months ago), we have had to restore the Database a few times from backup. mainly from junior administrators opening the AppCentre from a host other than a data collector, being impatient during editing a citrix policy & trying to click around. This resulting in crashing the console. After trying to reopen, we find all the policies had disappeared except for the one that was being created/edited.

What sort of maintenance should I be doing on our Data Collectors & the Database Server?
The Data Collectors are both Win 2008 R2 SP1 with XA65 RP4 installed.
Database Host is Win 2008 R2 SP1 with SQL 2008 R2

You need to user SQL tool to backup your data store DB, Here is the steps to backup\restore the data store in citrix http://support.citrix.com/article/CTX135207

Whenever you restore the data store, run dsmaint recreatelhc to get update on your data collector server

For the database side you'll need to run periodically reindex and rebuild jobs so the indexes and statistics can be up to date since it has a big impact on the performance, specially if your data grows a lot and quick.

I ran the dsmaint recreatelhc tool on the data collectors (rebooted after). Doesn't seem to have helped.

Regarding reindexing, I am not really an SQL expert, so I found a query online which I copied & pasted. Also doesn't seem to have helped.

The App center can take up to 1-2 minutes to load now and navigating around it will 2 out of 3 times cause it to freeze up for 20 seconds when I click anywhere in it.

Perhaps it is not Database related? It does the same thing when launching the App Center from either of our 2 Data collectors, or from one of the app servers.
