Issue/Introduction

Question:

My USM portlet and alarm portlet are exhibiting slow performance. At times I see the flash plugin is crashing. I am not seeing any errors in the portal or wasp logs.

 

What can I do to resolve this problem?

Resolution

In UIM / UMP there are several things you can check:

 

1) Check that the CPU and memory on the UMP machine are not above 75% utilized

2) Check the disk IO and make sure the disk queue length is less than 1

3) Use the attached check SQL index fragmentation script to make sure all indexes are below 30% especially on the CM_* tables.

4) Check the nas_transaction_summary table and make sure the files are being groomed by the nas probe. If not, deactivate the nas probe and drop all of the nas_* tables on the back end.

5) Lastly, you can check the Maintenance_* tables for  large numbers of entries, e.g., 40k or more. See KB KB000106216 in regards to cleaning up old maintenance schedules.
