SQL & PL/SQL :: Partition Of Existing Table
Nov 30, 2011We have a transaction table and has 30 million rows. The table is not partitioned till date. We need to create partition on this table. We had an idea of moving this data to a temporary table and create partition[range]on the original table and move the data back.

Partitioning - Switch Partition Key On Existing Table?
Jan 23, 2011I recently started working with legacy code and noticed that some huge tables (5 years worth of data, don't have more details on me right now but can post later if needed) are partitioned based on time sequence number column while majority of queries are done based on time (different column). Queries performance is degrading and I'd like to try to modify partitioning and run some tests to evaluate performance improvement.
My only concern is with so much live data I have to come up with solution on how to switch partitioning with the least impact on applications running 24 x 7. Something you have done in the same situation and it worked?

Server Administration :: Create Subpartition For Existing List Partition
Dec 14, 2012We 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.

Convert Some Existing Materialized Views (fast Refresh) To Partition Materialized Views
Jul 7, 2010I have to convert some existing materialized views (fast refresh) to partition materialized views.
Database version is oracle 10.1.0.4. I have decided to use on prebuilt table option to do the partitioning as it minimizes the time to transfer from the master site.
1) stop replication
1) create interim tables with similar structure as the materialized views
2) transfer all data from the materialized views to the interim tables
4) script out the materialized views structure and add in on prebuilt table option in the scripts
5) drop the materialized views
6) rename the interim tables with the same name as the materialized views
7) run the scripts to create the materialized views with on prebuilt table option
8) refresh the newly created materialized views -> it should take a short time since I am using on prebuilt table option
But I am facing one major issue. That is if I drop the materialized views, the materialized view logs of the master tables are purged. When the materialized views are refreshed fast, there are some data missing. the data that are purged out when the materialized view are dropped.
Do you happen to know other ways that existing materialized views can be converted to partitioned materialized views? Do you have any workaround to prevent the materialized view logs from being purged?
How To Partition And Index The Table
Oct 24, 2011how to partition and index my table for a special problem.
The table:
CREATE TABLE TEST (
ID NUMBER PRIMARY KEY,
U_VALUE NUMBER NOT NULL, -- Ranges from 0 - 30.000.000
O_VALUE NUMBER NOT NULL, -- Ranges from U_VALUE - 30.000.000
CREATE_TS TIMESTAMP DEFAULT SYSTIMESTAMP NOT NULL,
UPDATE_TS TIMESTAMP NOT NULL,
ITEM_TYPE NUMBER NOT NULL --<< Only 4 different values >>
);
As you can see, U_VALUE is ALWAYS lower than O_VALUE.I need to have the CREATE_TS in either main- or subpartition do drop the partitions after some time so i don,t have to use DELETE statements. The table has 360 millions rows.
The application has only 8 query which will always use a WHERE clause like this:
SELECT * FROM TEST
WHERE U_VALUE <= :1 AND O_VALUE => :2 AND ITEM_TYPE = :3
1. Is there any good technique how to create a good index for the queries (application will execute 120 queries per second)?
2. how to partition this table?

F_TFP_CP_MONTH P_201107 1627218307
All partitions were dropped, but three; these three returned the same error when trying to drop them:
SQL> alter table dw.F_TFP_CP_MONTH drop partition P_201112;
alter table dw.F_TFP_CP_MONTH drop partition P_201112

So, the situation now is that the table only has these three partitions, and we are not able to empty the table, so that we can later purge it and recover the
space.
free that space and empty the contents of the table?
