This is a follow-up to 2 posts I wrote in the past. To avoid index fragmentation and the issues I had with sets in the past I implemented 2 SQL Jobs to keep them clean.
Speed up FIM 2010 R2 SQL performance by rebuild/reorganize indexes
FIM 2010 R2: SQL timeout on using large sets in other sets
For around a month now the following to SQL jobs work perfectly in my customer’s environment even in production, so I think it seems to be safe to implement this, but you should test them on your own.
By default both SQL jobs run weekly on every sunday.
The first SQL job starts a PowerShell script to maintain the indexes on all tables of the FIMService database. The script works only on indexes with fragmentation higher than 20% and will only rebuild 100 indexes per schedule (You can adjust this in the script).
The PowerShell script is not my work, see author information in the scripts URL.
Make sure you replace the DOMAIN\USER and SERVERNAME placeholder in the script to values that fits to your environment.

The second SQL job uses the SQL internal function to do a rebuild on the FIMService full text catalog. You can user this SQL script or the build-in wizard to create this job.
If using this script make sure to replace the DOMAIN\USER placeholder to values that fits to your environment.
