I mistakenly added a datafile to a tablespace which is asm, however the datafile was created in a default location and not the asm location:
alter tablespace pdaiidata1 add datafile '<filename>' size 2048M;
What I should have done:
alter tablepsace <tablespace_name> add datafile '+DATA1' size 2048M;
Is there any way to move this filesystem datafile into the asm tablespace? In previous Oracle versions, I've taken a tablespace offline, moved a datafile, renamed it, then brought the tablespace back online. Can I do something similar here in this situation?

Are there any good information about on how to move a 10g database to a new server? We will keep the same disks on the SAN, but make a new installation on the new server.

I have a range partitioned table with one lob column. Each partion is on a separate tablespace except two partitions which are on same tablespace. Now I want to move a partition from one tablespace to another tablespace along with lob data. By using a simple alter table move partition will also move the lob data or there is some special procedure to adopt.

We got a request to take offline for few unused partitions and move it to a another drive (lease used).Please set the following partitions offline in PreProd:
MONTH_20110901
MONTH_20111001
MONTH_20111101
MONTH_20111201
MONTH_20120101

Please move the offline partitions to the E disk.How can we do this ?

How can i check whether a partition tbale have default partition?
View 9 Replies View RelatedI am using compress partition for a large table.During the process I have used the below command for compress---
1. ALTER TABLE <TABLE_NAME> MODIFY PARTITION P1 COMPRESS;
However I found there are different command as below:-
2. ALTER TABLE <TABLE_NAME> MOVE PARTITION P1 COMPRESS;
What is the basic difference between these two as the compression is happening for both command.
How can i check a partition whether it has been compressed? just as flowing test,i can not get the information about partition P_L1 whether been compressed.

I have a partitioned table - 128 partitions.
If I am not using data of many partitions in any way, will it affect my performance if I am firing select query that uses other/active partitions data.
How can I check when that partitioned was last accessed, also can I brought those inactive partitions offlie? If we can, what will be the advantages or disadvantages of that?
I am not able to exchange partition by following below steps:
drop table manu_tst_hashed_tbl_org;
drop table manu_tst_hashed_tbl_bkp;
drop table manu_tst_smpl_tbl;
CREATE TABLE manu_tst_hashed_tbl_org
[code]...
and getting the below erro:
ORA-14097: column type or size mismatch in ALTER TABLE EXCHANGE PARTITION

*Cause: The corresponding columns in the tables specified in the ALTER TABLE EXCHANGE PARTITION are of different type or size

Is there a script that it create partitions by auto? who can share it?
View 1 Replies View RelatedI was about to move some tables from one table space to another but it seems it is not possible to move partitioned tables between table spaces of different block sizes.
So far the only option I have is to export and then import back the data.
know if there is any way to move a partitioned table between table spaces of different block size?
We have a table which is already partitioned by list and now we would like to add a subpartition.
Create table Item_mst
(
ccn varchar2(10),
Flag varchar2(1),
Item varchar2(10),
status varchar2(1)
)
[Code]..
Now I could like to alter the above table for adding a new subpartition on each partition on status.
ALTER TABLE Item_mst
MODIFY PARTITION Item_mst_Test
ADD SUBPARTITION Item_mst_Test_A VALUES ('A');
Above alter gives ORA-14253: table is not partitioned by composite range method.
However dropping and recreating the table with subpartitions is working fine.
But Dropping and recreating the table in production is very cumbersome as it has huge data and many indices.
While trying partition exchange feature of Oracle with 2 hash partitioned tables, I come to know that I can't directly exchange partitions between 2 partitioned tables
I have two hash partitioned tables , so to move partition data from one table to another will include-
1) Exchange from partitioned table to non-partitioned table.
2) exchange from non-partitioned table to new partitioned table.
But I am not sure in which hash partition my data will go in new partitioned table (data need to be moved has single key value on basis of which tables are partitioned),
