I'm running the following script
logged in to schema - TESTUSER1
Begin
DBMS_STATS.GATHER_SCHEMA_STATS(ownname=>'TESTUSER1',options=>'GATHER AUTO');
End;
this does not work, it comes out immediately without giving error.
It works if I give ..
logged in to TESTUSER1
Begin
DBMS_STATS.GATHER_SCHEMA_STATS(ownname=>'TESTUSER1');
End;
But the script 1 works fine in another schema
i,e.
Logged to TESTUSER2
Begin
DBMS_STATS.GATHER_SCHEMA_STATS(ownname=>'TESTUSER2',options=>'GATHER AUTO');
End;
I do not understand why it is so..
Brian.

As usual, No Oracle version specified and no real session posted.
So this could take a little while to guess things out.
How are you saying that is working and not working?
Delete the stats. gather the stats. check num_rows or somehing like that. Accuracy of the stats depends on size of your bucket.
how many objects in testuser1 and testuser2?
Are those two schema's identically same?
By specifying AUTO, you are leaving the control to oracle.

Hi,
Orcl Version - 9.2.0.7
I'm submitting DBMS_JOB. If I issue following within no time it finishes.
Declare
job number;
Begin
DBMS_JOB.SUBMIT(job,
'Begin
DBMS_STATS.GATHER_SCHEMA_STATS(ownname =>''TESTUSER1'',
options => ''GATHER AUTO''
);
End;',
Sysdate + 2/1440, 'NULL' );
End;
My doubt was why it is finishing within 1-2 seconds(I'm not sure it is doing the job or not). 2 days back it I've gathered stats with the same script.
It worked fine with
Declare
job number;
Begin
DBMS_JOB.SUBMIT(job,
'Begin
DBMS_STATS.GATHER_SCHEMA_STATS(ownname =>''TESTUSER1'' );
End;',
Sysdate + 2/1440, 'NULL' );
End;
Brian.
