APPLIES TO

This article was previously published under Q153584

SYMPTOMS

The SQL Server updates the index statistics on some SMS tables during every Data Loader service processing cycle. This almost constant updating is inefficient and could adversely impact the performance of SQL and SMS on sites that process a large number of systems and MIF files.

CAUSE

The SMS Data Loader issues an UPDATE STATISTICS command to the SQL Server during every processing cycle. In most cases, this is done to keep SQL Server indexes efficient. Since this is done during every Data Loader processing cycle, this could impact SQL Server and SMS Data Loader performance.

RESOLUTION

This has been fixed in SMS 1.2. The SMS 1.2 DATA LOADER service will issue this command to the SMS tables every 48 hours between the hours of 12:00am to 5:00am.

STATUS

Microsoft has confirmed this to be a problem in Systems Management Server versions 1.0 and 1.1. This problem has been corrected in Systems Management Server version 1.2.
