This table is being loaded daily with lots of data. relation between DSET_COB_DT to DSET_UID is 1 to many. meaning, for a given date DSET_COB_DT = NOV 27,2012 there will be many DSET_UID=1,2,3,4
DSET_COB_DATE DSET_UID COLUMNA COLUMNB
NOV-27-2012 1 AB CD
NOV-27-2012 2 BC DC
NOV-27-2012 3 CB DA
NOV-27-2012 4 BZ CE
I have the above rows in the table such that all above rows are in one partition for nov-27-2012 and each row is in it's own sub-partition.
In order to gather statistics at the sub-partition level as soon as sub-partition is loaded with the data ( i will come to know when the sub-paritition is loaded with data for the day by some other means.) , i need to know the sub-partition name.
how to know what is the sub-parition name when all i know is DSET_COB_DT=NOV-27-2012 and DSET_UID=1.
when i know the sub-partition name, i can pass the sub-partition name to Gather Statistics procedure.
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.
I Know we can create dynamic partitions on table in oracle 11g. Is it possible to create normal partition and sub partition both dynamically.I have to create Normal partition range on date and sub partition list on Batch ID (varchar).
I have a table that partitioned into six partitions. each partitions placed in different table space and every two table space placed it on a different hardisk
when I will do query select with the non-partition keys condition, how the search process ? whether the sequence (scan sequentially from partition 1 to partition 6) or partition in a hardisk is accessed at the same time with other partition in other hardisk. ( in the image, partition 1,4 accessed at the same time with partition 2,5 and 3,6)
Can I add range sub partition to a hash partition table. Example like this.
CREATE TABLE test ( test_id VARCHAR2(10 ) , test_TYPE VARCHAR2(5) , CREATE_DATE date ) partition by hash (test_id, test_type) Partitions 3 SUBPARTITION BY RANGE (CREATE_DATE);
When Tried, I am getting syntax error as invalid option.
Activity Structure ACTIVITY_TYPE CHAR (1) NOT NULL, ACTIVITY_DATE DATE DEFAULT sysdate NOT NULL, ACTIVITY_ON VARCHAR2 (30) NOT NULL, REFERENCE_NO VARCHAR2 (19), CHILD_REFERENCE_NO VARCHAR2 (19), USER_ID VARCHAR2 (30) DEFAULT user NOT NULL, TERMINAL VARCHAR2 (30) DEFAULT userenv ('TERMINAL') NOT NULL )
Activity1 Structure Which I have Done Partitioning When I insert data from Activity to Activity1 it gives that error ORA-14400: inserted partition key does not map to any partition what I am doing wrong
CREATE TABLE ACTIVITY1( ACTIVITY_TYPE CHAR (1) NOT NULL, ACTIVITY_DATE DATE DEFAULT sysdate NOT NULL, ACTIVITY_ON VARCHAR2 (30) NOT NULL, REFERENCE_NO VARCHAR2 (19),
[code]....
Insert Statement
insert into ACTIVITY1(ACTIVITY_TYPE, ACTIVITY_DATE, ACTIVITY_ON, REFERENCE_NO, CHILD_REFERENCE_NO,
I have partition based table one the basis of year month. And we have 8 local indexes on this table. Every month we have to create a new partition and load data into this partition and the volume of the data is around 14million and the load process is taking long time due to indexes. Is it possible to drop the indexes from particular partition?
When I am trying to insert record from tbl_mittal into tbl_temp table. I am facing "ORA-14400: inserted partition key does not map to any partition" error
SQL> insert into tbl_temp select * from tbl_mittal; insert into tbl_temp select * from tbl_mittal * ERROR at line 1: ORA-14400: inserted partition key does not map to any partition
AS tbl_mittal is having hugh number of records so I am providing only few rows from tbl_mittal table as test data.
For the above data set i need to divide into 5 partittions and need to updated the partitonid with the partition number for each partition set,like the below result set
How to find the size pf a partition in a partition table?I guess we need to query views like dba_tab_partitions but I am not very sure. will running dbms_stats.gather_table_stats('schema_name,'table_name,'partition_name')
I think that performance better partition table than non-partition table. How to assure partition table is better than non-partition table at SELECT operation?
I have compare a specific query EXPLAIN PLAN at partition table and non-partition table. both tables data is same. Is it true way or not?
I have a partitioned table in which at the first level it is been partitioned based on date column(C1) and within in each partition it is again sub-partitioned based on a column(C1) which is a numeric value now at first level(C1 column level) there are 6 partitions and in the last partition i want to add another partition how can i do that.
I am trying to add partition to table without partition
with following code
ALTER TABLE ACC_LOC1_TAB ADD PARTITION testpart BY RANGE (ALT_AUTHDT) (PARTITION UPTO_2010 values less than (31-mar-2010), PARTITION APR_JUN_10 VALUES less than (30-JUN-2010), PARTITION JUL_SEP_10 VALUES less than (30-SEP-2010), PARTITION OCT_DEC_10 VALUES less than (31-DEC-2010), PARTITION JAN_MAR_11 VALUES less than (31-MAR-2011))
I am using Oracle 11.2.0.1 Oracle Database.I have a table with 10 Million records and it's a Non Partitioned Table.
1) I would like to partition the table (with partition by range ) without creating new table . I should do it in the existing table itself (not sure DBMS_ REDEFINITION is the only option ) (or) can i use alter table ...?
2) Add one partition which will have data for the unspecified range.
Can i alter the table to create partition on non partition table, i have tried and could not create it. Do we have some other means to do it as this is the live table and cannot drop them else will lose the data.

I am a new Oracle DBA that has been tasked with creating some single node databases for our programmers to connect to. I have never built a database, only upgraded. I will be using a Dell 610 with 10.2.0.4 software. I have been reading the install guides but cannot find a definitive answer for how to create the raw partitions. I have a SAN that I can utilize and my current db is set up with RAID 6 like so:
Disk 2 300 GB 1 Extended 300 GB and 5 logical, 100MB, 30 MB, 100 GB, 100 GB, 100 GB Disk 3 100GB 1 Extended 100 GB and 3 logical 100 MB, 30 MB, 100 GB
why the old DBA partitioned this way? I am not good with storage and know that I need to understand before I build new databases so I do not duplicate something that is wrong. I was reading articles that recommend SAME but would not know how to do that on the SAN.
I will be using data pump to export the database and import to the new server. I was looking at using transportable tablespaces to do this. Would you recommend that from the cluster to the standalone?
1) Alter table STS.DNA_ACCESSION add PARTITION DNA_ACC_P143 VALUES LESS THAN (286000000); ORA-14074: partition bound must collate higher than that of the last partition

There is a customer_account table. It is partitioned by Range. In one of the partition, the range value is given wrongly, and irrelevant data sits in that partition.
How can i modify the range partition value and re-arrange the data ?
I have a question related to partitions and dividing into subpartitions on the existing table.Situation is as follows:
1. we have an inventory table with a list partition on one column sales_desk_id. 2. This table contains millions of records. Due to concurrency and due to high amount of data inserts, now there is a need to make sub partitions based on sale_date.
Question: is there any way to make the subpartitions without dropping the tables?

we have our production database running on 11.2.0.2. I have a user table which has partitions. i would like to drop the partition and seeing weird issue:
The command to drop the partition i have is:
alter table SA.accounts drop partition dec_20111203 update global indexes;
Say after 10 minutes, the session is terminated and we are seeing the following: ORA-00028. We don't have a process that kills the session so we are trying to find the root cause why the session is being killed. what might be going on? also as an alternative - i was looking to do the following and want to know - if this works or not:
ALTER TABLE sa.accounts TRUNCATE PARTITION dec_20111203;
I ran exchange partition from non-partitioned table to a partitioned table with the following params: WITHOUT VALIDATION UPDATE GLOBAL INDEXES since we have a GLOBAL index( the GLOBAL is a must). After the exchange , if I'm running a simple query on the first column of the PK the plan is very bad and the EM Adviser advices me to build an index based on that column. I'm using 11.2.0.2
how 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)?
