Server Administration :: Convert Dictionary Managed Tablespace To Locally Managed Tablespace?

Jan 6, 2012

I have one database which is recently upgraded from oracle 8.1.5 to oracle 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.

I've got one database which was Initially upgraded from Oracle 8i to 10.2.04 running on windows. Most of the tabespaces are Dictionary managed. Do you think moving them to locally managed tablespace would give me better performance?

if Yes, what approach I should apply to move them to locally managed? I would like to do this with minimum/no downtime.

CORE Production
TNS for Linux: Version - Production

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.

ODP.NET :: Wallet (file Method) Compatible With Managed Driver

Oct 8, 2013

I am trying to use oracle wallet with the new managed driver, but I am getting

"invalid username/password".

As the wallet itself is ok (it works with the unmanaged client), seems to me that this new provider is not fully compatible with Oracle Wallet. Is this true? I am trying this: 

<oracle.manageddataaccess.client>    <version number="*">  <settings> <setting name="tns_admin" value="D:oracleproduct11.2.0client_1
etworkadmin" />        <setting name="WALLET_LOCATION" value="D:oraclewallets" />      </settings>    </version>  </oracle.manageddataaccess.client>

Server Administration :: How To Undo Tablespace Size

Feb 7, 2011

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'?

SQL> select b.tablespace_name, Total_Kbytes_Available/1024 Tot_Mbytes_Available,
Kbytes_alloc/1024 Mbytes_allocated, kbytes_free/1024 Mbytes_Free_from_allocated,
((Kbytes_alloc - kbytes_free)*100/ Total_Kbytes_Available) Pctused
2 from ( select sum(bytes)/1024 Kbytes_free,

Server Administration :: TEMP Tablespace Estimation

Oct 12, 2011

We have a database running with Oracle 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'.
