Posted on 19-Feb-2007 By Admin No Comments on To Find Orphan OS processes.

Another Tuning Article for subheap of shared pool

Posted on 16-Feb-2007 By Admin No Comments on Another Tuning Article for subheap of shared pool

http://www.mail-archive.com/oracle-l@fatcity.com/msg79721.html Oh yeah, I forgot to say that in 9.2.0.3 the shared pool was broken up into “heaps” (Oracle terminology) but whatever fancy stuff they were trying to accomplish by doing this (I think part of the magical self-tuning initiative) was buggy and this hastened the fatal 4031 situation. There is a parameter (so I…

First, a subpool must be at least 128MB in 9i releases and at least 256MB in 10g releases. Bugs and internal tests show that subpools around 500M will work most efficiently and in future versions, we…

The INDEX_STATS view will hold information for one index at a time: it will never contain more than one row. Therefore you need to query this view before you…

Posted on 06-Feb-2007 By Admin No Comments on Composite Index creation tip from Vivek

When you create a composite B-tree index, you should consider the following. The most restrctive condition: The condition that returns the least number of rows. The column that is involved in this condition, should be the leading column of B-tree index. So for finding the candidate of composite index columns, column order should be.. (…
