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?
In an attempt to take older data off line and allow database refreshes to be faster, tablespaces associated with partitioned table data for a given time period was taken off line, leaving only tablespaces that relate to the current time period online. In effect, tablespaces related to 2010 and earlier were taken offline from a table.
1. Without giving a filter on the partition key (the business date) to scan for data greater than the dates in the off lined tablespace partition, we get a ORA-376/ORA-1110 error (data file cannot be read at this time).
2. Materialized views using fast refresh or refresh on commit, will also not work because of the partitions being off line.
Queries directly querying the tables are manageable from an application point of view.But the materialized views failing to aggregate is a bigger problem.
how we can manage this situation? I know that I can move the partitions to a different table in a tablespace to be taken off line. But if possible, we wanted to solve this without doing a move partition.
I want to drop a datafile in my test db which is in no archive mode,at first, i want to offline the datafile,but it failed,is there any way to do it?

I have created an user named "Raja" with a default tablespace as "Raja_TBS" along with a datafile "rajadata.dbf". I have taken the tablespace offline
SQL> alter tablespace raja_tbs offline;
Tablespace Altered. when I take a tablespace offline, which means I cannot read or write and the tablespace is currently unavailable for users. I am still able to create a table on the "Raja_TBS" while it is offline.
when i make a datafile offline,can i add the following option: normal or immediate?
such as like here:
SQL> ALTER DATABASE DATAFILE 5 OFFLINE NORMAL;
OR
SQL> ALTER DATABASE DATAFILE 5 ONLINE IMMEDIATE;
when i try a test ,it occurs an error:ORA-00933.
i'm facing a problem while i'm inserting millions of record from table to table that undo tablespace reach 100% full and execution aborted. , how can free the undo tablespace ??? many of extendes are offline. will it flush automatically ??? or what i should do

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:

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.

Is there a script that it create partitions by auto? who can share it?
View 1 Replies View RelatedWe 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),
Any impact is there if is do the following:
ALTER TABLE MY_TABLE TRUNCATE PARTITION P1 UPDATE GLOBAL INDEXES;
will there be any lock on the table during this operation? DML operations will work without any issue or not?
The table tb_hxl_hash have two partitions,when i exchange the second partition,it raise error,why?

I am exploring the options for file based databases for offline applications where there are no overheads of database installations. We have a system which has Oracle database with more than 500 tables. We need to write a lightweight application (offline) in .net which will run from USB drive and write data to USB drive only.
Existing system has a data layer which writes data to Oracle 10g Enterprise Edition database. The offline application will have more or less similar data entry forms and storage structure. In order to reuse data layer of existing system (stored procedures) can the Oracle Lite be used as a database which can run from USB drive?
I understand Oracle Lite has a suport for synchronization with the server (our main database in this case) by which data can be synchronized with minimum overheads. How the Oracle Lite is licenced if I have 300 odd users of this offline applications. I need to use only database part of Oracle Lite and not mobile server.
I'm running 11.2.0I am looking at tuning a sql statement, and the question was brought up as to the max inserts per transactions in 11g, and if it exceeds 1000.I haven't found a solid answer yet, but I thought that 10g was higher than 1000.
My first thought was to implement a commit loop on every 1000 rows, as that is how things were handled in the past.But I found an article that talks about redo logs and performance and how it's a horrible practice to do the commit loop.
What I haven't found is what is the better methodology in doing this?My scenario could encounter inserts as much as 20,000 at a time.
For an query, cost was 16Lakhs and was taking 30min, I brought down the cost to 1.5lakhs, but still it is taking 30min.
There were many outer joins and same table has been Used(FROM clause) 5 times in the query. I have introduced WITH clause, and brought down the cost.
i have table with range partition and list sub-partition..can i add one more list sub-partition if it is not possible , i have to drop first sub-partition.
