I have a partioned table that has close to 2 billion rows and a PK of all columns. Becuase of time constrains my APP team wants the PK disabled while they pump into hundreds of thousands of rows with a batch process.
Now I am finding when I enable the PK its eating up close to close to 200GB of temp space.
Is there something I can do to reduce the amount of temp space being used?
splitting a table partition without making its primary key index ar any other indexes unusable.
I think it is possible to do so 10g onwards.
DB Details:
Oracle RDBMS 11.2.0.3, HP-Ux B.11.31, OLTP
I'm new into Oracle, consider the below scenario and respond it accordingly.
I want to add 500GB data file at primary database side, but doesn't have space at standby database side. My STANDBY_FILE_MANAGEMENT is set to Auto.
I 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 deleted millions of records from a table.
1.Is it necessary to reorganize a table and index after the deletion of records from table ? Because i see some change in table size after table and index reorganization.
2.Will re org table and index improve the database performance ?

if a table contains two columns and both are part of the primary key of that table (Kind of obvoius).
should i opt for a index organized tbale in this case ?Or should i opt for another running sequential colum which would serve as a primary key of this table and define the actual two columns of the system as unique keys.
there is a drawback if a most of the tables of a database contain composite primary keys?
In our database without enabling audit file, we are getting audit file.find the audit parameter output

I have an existing form which i need to customize..In the form in the query block whatever strings we enter..and press the search button..it sets the where clause and use execute query.which populates the detail block which is read only and only 1 column is enabled.
For the Enabled column X I need to enable a button.It has to be done only if the cursor go in the column X
Is there any way to enable the constraint with out validating for the existing information.
As We can accomplish the same functionality when we are adding the constraint for the first time.
Ex: alter table scott.emp add constraint fk_deptno foreign key(deptno) references scott.dept(deptno) enable novalidate
The above SQL statement will enable the constraint with out validating for the existing information. So there is possibility of data will be there only in the child table but not in the parent table for existing information.
But in the future it will not allow to do so,if the constraint is in ENABLE staus.So i am just trying to disable the constraint to insert only into child table & trying to enable it with NOVALIDATE option .
But the following exception is coming .
SQL> alter table scott.emp ENABLE constraint fk_deptno enable NOVALIDATE;
alter table scott.emp ENABLE constraint fk_deptno enable NOVALIDATE
ORA-00905: missing keyword
SQL> alter table scott.emp ENABLE constraint fk_deptno NOVALIDATE;
alter table scott.emp ENABLE constraint fk_deptno NOVALIDATE
ORA-00933: SQL command not properly ended
Instead of dropping & recreating the same constraint , is there any alternate way to do this ?
I developed a custom form upon which I developed a query find block to query the data on the main form. I have WHO columns in the table and referencing them in the main form. But Some reason when I query the data by pressing the find button on the query block it is retreiving the data properly, but record history is not enabling.
In the query find block I have 3 text fields, 1 check box and 2 date fields.
There is a huge table,i want to compress it,how can i do? alter table tb_my_table compress After executed the sql,the size of table have any change.

I have scheduled a ADHOC Oracle JOB in OEM to gather statistics for the database with 100% estimation during weekend. This JOB currently fails because of a batch Job that runs at the same time and drops few old partitions. This OEM job runs for 1 hour and fails because few partitions are getting dropped at the same time.
How i can enable this statistics JOB to skip/Ignore errors and to continue to run to gather complete statistics of the entire database. I have scheduled this job in OEM. how can i enable this SKIP/IGNORE errors for this job.
My requirement is as below,
I have one main form and there is one button when i click on it, another form should be opened which should display multi records with check box for each record.
I have implemented so far. When the new form is opened by default all the records should be checked. if user does not want some of them then it can be unchecked(This can done manually)..
I have put below code in when-new-block instance trigger
set_item_property('LOCKBOX_DETAILS.CB_SUBMIT', ENABLED, PROPERTY_TRUE);
Unable to load the block with all the records checkboxes checked.
We are running 11g (11.2.0.3)We have a "working table" that is empty at the beginning of the day.Then we start adding rows (insert) with a key column called STATE with a value of 100.At the same time, there are other apps that pickup data in state 100 , process that data and change that state to 200 or 300.There is also another app that pickup data in state 200 , process that data and change that state to 300 or 400.
So in summary, the data on that table is at the beginning empty, then all the rows are in state 100, they slowly move to different states (200, 300, etc) and by the end of the day, they are all in 400.
My question is what would be the best way to collect stats on this table?
I was thinking to create an hourly job to collect stats on that table:
exec dbms_stats.gather_table_stats (
ownname => 'SCOTT',
tabname => 'WORK_T
I have a table: desc STG_XML
Name Null Type

CREATION_DATE TIMESTAMP(6)
MODIFICATION_DATE TIMESTAMP(6)
ARCHIVING_DATE TIMESTAMP(6)
CREATED_BY VARCHAR2(50 CHAR)

The problem is that the data of the table are 40GB while on the DB the table holds 400GB! How can I shrink and reuse that space except from drop/recreate and drop/import?
The table has no initial data, so that I can play with the INITIAL parameter. Data are inserted, updated and deleted all the time. I have run DBMS_ADVISOR which recommended to SHRINK table. I have performed the shrink :
alter table STG_XML shrink space COMPACT;
but I haven't gained any space.

Why do we gather table statistics manually ?Is it because of database performance.
I know In Oracle Database 10g, Automatic Optimizer Statistics Collection reduces the likelihood of poorly performing SQL statements due to stale or invalid statistics and enhances SQL execution performance by providing optimal input to the query optimizer.
Optimizer gathers statistics when 10% table rows have been changed.
1)i have 2 SWP TABLES. while dropping a column, i am getting error -
ORA-39726: unsupported add/drop column operation on compressed tables.
2) when i checked compression status, those were not compressed. But as per our code standard, SWP tables should not be in compress mode.
OWNER TABLE_NAME COMPRESS COMPRESS_FOR
------------------------------ ------------------------------ -------- ------------
NOVAR PAYMENT_SWP DISABLED
OWNER TABLE_NAME COMPRESS COMPRESS_FOR
------------------------------ ------------------------------ -------- ------------
NOVAR PREPAYMENT_SWP DISABLED
3) as a workaround, i compressed these 2 SWP tables with OLTP option, and then i was able to drop the column from these 2 SWP tables.
4) Below statement is correct or not ?
IF A TABLE USING BLOCK LEVEL COMPRESSION, THEN this error will come - ORA-39726: unsupported add/drop column operation on compressed tables.
if above statement is correct, then how to find out whether table data is using block level compression ?
5) we have DBMS_COMPRESSION.GET_COMPRESSION_TYPE. using this i just tried to find out, but i am getting "1" as output. I am not getting the exact meaning of it.
confirm what is the conclusion on this ?
