Alerter Takes Several Hours to Retrieve Rows

Article ID: Q153552

= SYMPTOMS =

Creating a large site-limiting query may cause the alerter to take several hours to monitor the query for a specific condition.

= CAUSE =

There is an issue in CQueryExec where site-limiting a query with no format columns adds a table to the query without performing a join, therefore returning the cartesian product of the Identification_SPEC table and the distinct list of MachineIDs. Although RetrieveResultRow only returns one row per machine ID, the mere act of getting the distinct list takes much longer than expected, especially if there is a lot of dataloader traffic.

= STATUS =

Microsoft has confirmed this to be a problem in Systems Management Server version 1.1. This problem has been corrected in Systems Management Server version 1.2.
