My Oracle db have this tablespace named INDX which is 80% full. I tried to query on the table, user using it but there is no one using this tablespace
May I know if there is a query that i can used to find out which dba_object is consuming the 80% of this tablespace.
I have create one table emp under scott schema, and this schemas default tablespace is USERS and this tablespace has 3 datafiles.
Now how do I identify the object EMP is residing on which datafile in USERS tablespace?
i have a tablespace which contains 121 datafile(max limit reached) as a dba what we have to do?
creating a new tablespace with a datafile and assign the users to the current tablespace which i created now.iif the above process is correct,after some time the tablespace which was filled up got freed up.now can i give the access to the users previous (i.e. freed up tablespace) and current tablespaces

My database is OLP system.
My question is what are the advantages and disadvantages having one single tablespace versus multiple tablespace?
Easy to maintain when you have single tablespace. but hard to track the IO issues if you have one single tablespace.
Are the terms object and segment same ? what are the differences between them? what are similarities between them?
View 3 Replies View RelatedI have one database which is recently upgraded from oracle 8.1.5 to oracle 10.2.0.4.The database is having around 300 tablespace and total size of the database is 1.5 TB.
The database was created in oracle 8i and all the teblespace were DMT(Dictionary Managed Tablespace) .Usually after up gradation all the tablespace are in DMT mode. Now my requirement is to convert all the tablespace into LMT (Locally Managed Tablespace) so that I can AVAIL ALL THE FEATURES OF LMT.
This database is a mission critical database and very less downtime can be allowed.
Whenever I create a table using login A, the table gets created successfully. But when I query the dba_objects, the object owner is different, login B. What might be the reason behind this?
View 9 Replies View RelatedWe had a new outsourcer who completed migration of 1 of our system running under Oracle10g-Solaris 10. We created an inventory script that will list all objects counts of SYS, SYSTEM and ORACLE and all other schemas. This script will be ran before (old server) and after migration (to new server). After migration to the new & bigger server, we noticed from the output of the inventory script for SYS/SYSTEM object counts had been reduced compared from the original/actual value (from the old server). Our outsourcer said that this is not an issue since SYS/SYSTEM objects are not transactional and cannot be controlled.
As we will conform that the migration was completed successfully by our new outsourcer.
Quote:Oracle collects new statistics when enough of the data (about 10%) has changed.I read the above statement in the oracle documentation that Oracle collects new statistics when enough of the data (about 10%) has changed every day during 10 pm to 6am .

From v$session view,i found sid and serial# and at same time i queried dba_jobs and saw one jobs is running at this time.Now how to compile this object.

View 2 Replies View RelatedErroneously created datafile, re: "/path/../large_rbs_03.dbf" was created under the SYSTEM tablespace which is supposedly be in the LARGE_RBS tablespace.
How do I make the said datafile be under LARGE_RBS?
As the undo segments are used in round robin fashion, Is it possible that with varying load (concurrent users, size and number of transactions), the size of Undo tablespace on a particular day is less than the Undo tablespace size few days back, by any chance?
As a basic understanding I know that Undo is preserved for read consistency and transaction, instance recovery So if there are lot of transaction on a database on 05 Feb and before that, but there aren't any transactions on 6,7,8,9, then on 10th Feb can we see the Undo tablespace size is less than that of 05 Feb?
In the following case when data belonging to table is not required for any queries, transactions, even then the undo size is not restored upon dropping the table.
As such for large operations and batch processes shall we keep undo tablespace with files as 'Autoextend' with 'Maxsize' as 'Unlimited'?

We have a database running with Oracle 10.2.0.4 on Solaris 5.10 [SUN SPARC v240] where the assigned TEMP tablespace size looks to be quite huge ( = 8GB!). There are not much SQL queries being run on the database, but what can I do/find/investigate to be sure of how much TEMP space is 'actually' required for the application to run OK?
Note. I have seen the previous DBA's have marked AUTOEXTEND = ON for the TEMP datafiles as well.
Separate query (but linked to TEMP tablespace):
Even if the TEMP datafiles are created with AUTOEXTEND = ON, sometimes I am seeing 'ORA-01652: unable to extend temp segment by 128'.
we have a tablespace of size 900 GB where 90% of space is occupied by two tables having BLOB data and now i need to drop these two tables and then to recover the space, i need to resize the tablespace (datafiles).

The SYSTEM tablespace refuses to autoextend (3 segments in SYSTEM tablespace unable to extend). It sits on its current size of 559MB (auto set to 2GB, increment 10M).
I guess there are no free extends that are that big as 10M.
