Performance Tuning :: Create Versus Rebuild Index
Jan 27, 2011I was comparing cost of rebuild vs create index...I carried out the following test
SQL> create table t4 as select * from t1;
Table created.
SQL> create table t5 as select * from t1 where 1=2;
Table created.
SQL> create index i5 on t5(id);
Index created. SQL> select bytes,extents,blocks from user_segments where segment_name='I5';
BYTES EXTENTS BLOCKS
---------- ---------- ----------
65536 1 8
SQL> alter index i5 unusable;
Index altered.
SQL> alter table t5 nologging;
Table altered.
SQL> Alter session set skip_unusable_indexes=True;
Session altered.
SQL> insert /*+ append */ into t5 select * from t1;
563904 rows created.
SQL> commit;
Commit complete.
Now I compared the cost (elapsed time, logical I/O) of the operations
create index i4 on t4(id);
Vs
alter index i5 rebuild online;
Following is the related trace of above 2 steps
create index i4 on t4(id)
call count cpu elapsed disk query current rows

Apr 26, 2011We have separate tablespaces for Tables and Indexes. Also Temp is in different temporary tablespace and UNDO also in UNDO tablespace and Index tablespace contains only Indexes. The tablespace usage for tables is 80% and Index is 91%.There is not enough disk space to allocate for the datafile on our system. I ran a rebuild on one of the Index but now notice the Index tablespace is 98% used soon after the rebuild finished.
How can i free up space for Index tablespace and why does the size of Index tablespace increased after the rebuild.

Performance Tuning :: Analyze Stats Running Long
Jul 31, 2013I have a Datamart DB which has a continuously increasing volume. I run a daily optimize job, to have the data analysed using the below:-

Performance Tuning :: Audit Analyze Table On 9i Database?
Apr 19, 2011I support to get a handle on statistics collectionn in their data warehouses. It seems developers have created several ANALYZE TABLE jobs but the code for these is not stored as PLSQL in the database and thus it is problematic for statistics collection.

Is there a way to AUDIT ANALYZE TABLE? I can't find it anywhere.
Is there a way to globally turn of ANALYZE TABLE in a 9i database?

SQL & PL/SQL :: Procedure To Rebuild Partitioned Indexes
Oct 3, 2012I have a task to create a procedure that disables (particular) partitioned indexes and REBUILD after ETL load.
Developers wants 3 parameters for the procedure:
1) TABLE_OWNER2) TABLE_NAME3) TRANSACTION_DATE = 13-JUN-12
And here is what I have done. I have created a procedure that takes 3 input parameters, please see the attached script:
1) TABLE_OWNER 2) TABLE_NAME 3) PARTITION_NAME - requires to query the particular partition to get the partition name
a situation where they will input dates as the partition was on a DATE column, now my challenge is how to incorporate this into the procedure to accept DATE as an input which will require one to query the particular table to get dates.I thought of using (HIGH_VALUE - 1) to get the dates from ALL_IND_PARTITIONS.
