Dear SIR,

I have just got 8 months experience on databases and nobody to guide me.
I had to rebuild indexes and after rebuilding my indexes, of lack of experience, i later on moved my tables using
"alter table tblname move tablespace tbsname" command

which led to most of my objects being invalid.
AFTER RECOMPILING all the function/proocedures/triggers and packages etc. the TRIGGERS run very slow and there is not much improvement in the database either.

CAN you please help me to get out of this problem in a detailed manner.

thanks in advance,

AJAY SHARMA

It could be that you need to re-analyse your indexes. Check this chapter of the Oracle Performance Tuning Guide.

A lesser possibility is that you have some very large packages and your SGA is too small. The packages could be swapped in and out of the SGA. This is less likely though - check the statistics first.

Did you collect statistics on tables and indexes after moving/rebuilding the indexes?
If so, how?

THANK YOU SIR,

THERE WERE NO STATS ON THE TABLES WHICH HAD BEEN MOVED.

AFTER COMPUTING THE STATS I GOT THE REPORTS RUN FASTER AND ACCOLADES.

I AM SO VERY MUCH HAPPY.

THANKS AGAIN,
