Server Administration :: Recover Space After Index Rebuild?

Apr 26, 2011

We 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.

Server Administration :: Possible To Run SHRINK SPACE Against Table With Function Based Index

Jun 27, 2013

It is not possible to run SHRINK SPACE against a table with a function based index. This is documented, and I've tested on the current release. I've reverse engineered it a bit, and the issue is in fact that you cannot SHRINK SPACE if there is an index on a virtual column:SQL> SQL> create table t1(c1 number, c2 as (c1*2)) segment creation immediate;

Table created.
SQL> alter table t1 enable row movement;
Table altered.
SQL> alter table t1 shrink space;
Table altered.
SQL> create index i1 on t1(c2);
Index created.

SQL> alter table t1 shrink space;
alter table t1 shrink space

ERROR at line 1: ORA-10631: SHRINK clause should not be specified for this object.

SQL & PL/SQL :: Bitmap Index Rebuild - Getting ORA-00054

Nov 15, 2012

oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - 64bit Production
PL/SQL Release 11.1.0.6.0 - Production
"CORE 11.1.0.6.0 Production"

I have a procedure that is run weekly to load the data, for which it calls another procedure. This weekly procedure, disables the index, load the data, and rebuilds the index. During rebuilding of index, its giving ORA-00054: resource busy and acquire with NOWAIT error. I dont have privileges to look for session id, and kill the session. How to avoid this error.

create or replace
PROCEDURE "WCL_WEEKLY_UPLOAD" (
p_event_id IN NUMBER
)
[code]....

As you can see, after the procedure wc_upload, COMMIT is issued, and then the rebuilding of the index is starting. So dont know what is causing the table to lock.

Performance Tuning :: Create Versus Rebuild Index

Jan 27, 2011

I 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
------- ------ -------- ---------- ---------- ---------- ---------- ----------
Parse 1 0.00 0.00 0 1 0 0
Execute 1 1.17 3.38 9497 7869 335 0
Fetch 0 0.00 0.00 0 0 0 0
------- ------ -------- ---------- ---------- ---------- ---------- ----------
total 2 1.17 3.38 9497 7870 335 0

Misses in library cache during parse: 1
Optimizer goal: CHOOSE
Parsing user id: 5
[code]....

So which option we shall pick in such cases? {Of course I haven't set 'nologging' for the indices but it is same for both indices we are comparing}

Server Administration :: Drop Index Hangs On SAP?

Apr 14, 2010

On a SAP system, am trying to drop six indexes, largest is 300MB and smallest is 50MB.

I tried running drop index sapusername.index_name on the 50MB index via SQL*Plus and it seems to be taking forever. anything I can check on the database on why it is taking such a long time?

I can leave it to run overnight but worried that when I come back the next day, it will still be hanged. Is there any quick way of dropping the index, .i.e. drop immediate ...

Am not using SAP's BRTOOLs as it is also hanging from there and the SAP-ADMIN had approved for the DBA to drop it from our end instead.
