Performance problems caused due to indexes

edited Oct 2, 2012 12:45AM in Database Tuning (MOSC) 13 commentsAnswered
Hi All

I am having intermittent performance problems on a specific table due to it's indexes.

Rebuilding the indexes, fixes the performance problem whenever it occurs.

The developers want me to rebuild the indexes on a weekly / monthly basis and I am hesitant to do so, as my tablespaces are locally managed and i hardly ever find it necessary to rebuild any other indexes.

Just some information regarding the table:

The table is 7GB in size, and has 98 million records in it.

It has 6 indexes with the smallest being 1.5GB and the Biggest being 4.5GB.

Data does not get deleted from the table.

Howdy, Stranger!
