Server Administration :: When To Gather Table Statistics
Apr 21, 2012Why do we gather table statistics manually ?Is it because of database performance.
I know In Oracle Database 10g, Automatic Optimizer Statistics Collection reduces the likelihood of poorly performing SQL statements due to stale or invalid statistics and enhances SQL execution performance by providing optimal input to the query optimizer.
Optimizer gathers statistics when 10% table rows have been changed.

PL/SQL :: How To Grant Privilege On User1 Based On Privilege Of User2
Jun 20, 2013I have 2 users in my oracle DB. They both have very different privileges and they both have too many different privileges. Now I want to grant user 1 the same privilege that user2 has while user1 keeps his existing privilege. How can this be done without manually comparing their difference and manually grant user 1 each privilege that he doesn't have? Or second option, can I override user 1's privilege with user 2's privileges?

SQL & PL/SQL :: Updating Table Statistics - View Not Appropriate
Oct 22, 2010how many rows certain tables have.
updating the statistics for a table (with GATER_TABLE_STATS) and using NUM_ROWS then. This works fine for me as long as I am the owner of the table, but when someone else is, I always get this error: ORA-20000: Table does not exist or insufficient privileges.what privileges do I need to use GATHER_ TABLE_ STATS on all Tables, which were created by Users?
when I tried to use ANALYZE TABLE TEST_TABLE COMPUTE STATISTICS on a certain table I got the following error: a view is not appropriate here. The strange thing is, TEST_TABLE is not a view (at least it is not listed in ALL_VIEWS and is listed in ALL_TABLES, so it cant be a view right?).
Besides, is there another way to gather Table Statistics (not using Analyze Table or Gather_Table_Stats)?
PL/SQL :: Oracle 11g - Huge Table Statistics
Jun 13, 2012I have a table which have 300+ columns and have 13 million rows. It is on a 32 kb block size. This is a table in data ware house environment. There no# of rows in the table haven't changed much but I see that the time taken to collect statistics have increased significantly.Initially it took only 15 minutes (with the same 13M rows) now it runs for 4+ hours. The max parallel servers is 4 (which is unchanged). The table is not partitioned.
OS: HP UX Itanium
Database: Oracle 11g (11.2.0.2)
Command is:
exec dbms_stats.gather_table_stats(ownname=>'ABC',tabname=>'ABC_LOAD',estimate_percent=>dbms_stats.auto_sample_size,cascade=>TRUE,DEGREE=>dbms_stats.auto_degree);
I would like to understand:
1) What could have been the causes of this change in time. 15 minutes to 4+hours ?
2) How can we gather statistics of huge table at a faster rate?

=================================
select table_name, stale_stats, last_analyzed
from dba_tab_statistics
where owner= 'SYSADM' and stale_stats='YES'
order by last_analyzed desc
I collect stats for those above 3 tables with dbms_stats.gather_table_stats().But no luck.After collection of stats immediately I ran the above query.But still it is showing there are stale stats for 3 tables.
how can I change "STALE-STATS" status, so that optimizer can use the updated stats eficiently.

SQL & PL/SQL :: Grant Privilege To Role
Jun 3, 2010I have a stored procedure which when executed creates a user and grants some roles to the user and also makes certain roles DEFAULT using "alter user"
The issue comes when i execute the procedure.
I have a User who has a role and this role has the "alter user" privilege, for example lets say that the user1 has the role ABC, and role ABC has the "alter user" privilege.
SQL> grant alter user to ABC;
Grant succeeded.
SQL> grant ABC to user1;
Grant succeeded.
Now, when i run the stored procedure as the user1, it gives me an error on a line saying "insufficient privileges", when i check the line, its this line:
alter user user1 DEFAULT ROLE "ROLE1", "ROLE2"
But as far as i know the user1 has the "alter user" privilege
I want to make those two roles ROLE1, ROLE2 DEFAULT because i don't want the other roles ROLE3,ROLE4 to be default, as you know if there are many roles and if we alter user with default for certain roles other roles become DEFAULT=NO.
So i get the error at "alter user" statement though the user has the "alter user" privilege, what do you think might be wrong?
OR is there anyway to grant roles to the user with default=NO option?
