PL/SQL :: Oracle Database 11g - Add Partition Based On Amount Of Data To Be Populated
Oct 30, 2013
I'm using Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production and TNS for Linux: Version 11.2.0.3.0 - Production.Requirement is to create a script to add a LIST partition to some selected tables in a schema (tables do not have data, they are not partitioned). There are about 300 such tables (can vary) and their names are maintained in a separate table. Example -Existing table
-CREATE TABLE test_part(id number (2),
name varchar2(20),
audit_userid number (9));
Expected table
-CREATE TABLE test_part(id number (2), name varchar2(20), audit_userid number (9))
PARTITION BY LIST (audit_userid) (PARTITION p1_audit_userid VALUES (1));
Ultimate goal is to add more partitions based on the amount of data to be populated.

I have a range date partition table month wise which i want to truncate the partition and load for each month data i get from source.
How can i get the partion name based on data value.

SALES_IDSALES_DT
101/02/2008
101/03/2008

My problem:
+ Oracle 11g
+ Centos 5.5
+ I create many users by shell script (user01, user02, user03 ..... user0n)
+ How can I connect all user to Oracle database in Centos (may be create connect.sh) - command line env ?
......
// user01 , user02 ... ---===> connect Oracles ?
My idea: using fork to create multi sqlplus to connect but it cant o_0
If all users can connect to Orcl db, I can count real user connections.

I am using:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0
Microsoft Visual Studio 2010 : VB Express
Microsoft .NET Framework : Version 4.0.30319 RTMRel
When I populate dataset using select query and use OracleCommandBuilder and update dataadapter, data is saved in database.
But if I put same select in store procedure and use this to populate dataset then data is not updated in db.
I get this error
Update requires a valid UpdateCommand when passed DataRow collection with modified rows.
at da1.Update(ds1, "req") where I am going wrong.
Dim conn As New OracleConnection
Dim da1 As OracleDataAdapter = New OracleDataAdapter
Dim ds1 = New DataSet
With conn
If .State = ConnectionState.Open Then .Close()

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?

I have oracle 11gr2 database on linux os. It's total sga size is 500mb only. Now, if uses wants read the 1gb of data from database, then there is no sufficient memory in buffer cache. so how it will works. the transaction will get successful or it will fail.And i have another doubt, does oracle can read the data from memory only or it can also read directly from disk.

extract a huge amount of data from a couple of views... the problem is that they want it in TXT files with fixed record length. There will be like 6 files, for a total amount of about 10GB.
export those tables in the fastest possible way? If I'm not mistaken exp and expdp can't create txt files, so do I really need to use utl_file or spool?

Does the above finding means that IPPS has use up 'this amount' of space in the database from all his objects?

I have a central entity Address. I have other entities that could have many addresses (Organization, Person for eg). The relation between Organization and Address is one to many and the relation between Person and Address is also one to many.When I modelled it, I ended up having two foreign keys in Address (Organization ID and Person ID).The question that is being raised by the client is "As only one of the foreign key would be populated on each record, the other would be null". The client is not comfortable having nullable foreign keys as they won't be able to maintain integrity. One of the requirement is that No orphan records in Address. By modeling the way above, there are chances for having some orphanned records. I tried to explain that this would be controlled by the program to ensure that no orphan records would be there but their question is that what if someone goes directly and enters a record in Address table without any foreign key value (I dont know who would have an insert/update access on the tables other than the dba's).
I am trying to get some pros and cons on using the nullable foreign keys.

How can we partition a table based on date if it does not have a date column.
Actually I have to compare two tables on daily basis and fetch few rows from those two tables and enter it to a third table.But both these tables does not have a date column.
I am confused if i need to alter those tables and add date column or if there is some way in which i can compare the data from the two tables for that particular day only and not the whole table data.

I got a primary database with a logical standby database running Oracle 11g. I got two client applications, one is the production site pointing to the primary one, another one is just a backup site pointing to the logical one.Things will only be written into the primary database every mid night and client applications can only query the database but not add, update nor delete.And now, I want to apply the latest patch on both of my databases. I am also the DNS administrator, I can make the name server pointing to the backup site instead of the production one.I want to firstly apply the patch on the logical one, and then the physical one.
I found some reference which explains how to apply patches by adopting "Rolling Upgrade Method". however, I want to avoid doing any "switch over" mentioned in the reference because I can make use of name server. Can I just apply patches as the following way?
1)Stop SQL apply
2)Apply patches on logical standby database
3)let the name server point to the backup site
4)Apply patches on the primary database
5)Start SQL apply
6)Let the name server point back to the production site

I am working on forms 6i. I have one data block based on table EMP.
Datablock-A: Empno, Ename, Sal
I have FIND Screen: Empno, Ename, FIND Button.
I can search the data through FIND Screen and populate data in Datablock A.
I am using below logic to search data through FIND Screen.
When-Button-Pressed(FIND Button): calling 'EXECUTE_QUERY'.
In Pre-query trigger of DatablockA:
copy(:FIND.EMPNO,'BLOCKA.EMPNO');
copy(:FIND.ENAME,'BLOCKA.ENAME');
It's working fine. But below case is failing.
Let us say, if i enter empno 10 (which is not there in database) in FIND Screen --> press FIND Button, it's showing up 'QUERY CAUSED NO RECORDS', Till this point it's working fine;. But after this, if i press CTR+F11 in block A, it's not pulling records. only this case it's not pulling records.
But if i enter something else in FIND Screen, if it returns any data, then if i press CTR+F11,it's pulling all records.
why it's failing to pull records if i try to query data in first case only.

I have table and it will contain huge data, so we have implemented as partitioned table. Every day when we load data into table there will be one partition created by the ETL Process by default with the Date Column(day wise). Now we may receive data for the previous days as well(Date column in table will have the date associated to the Data). No i would like the data should be inserted into partition which assocites to its own date.

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 would like to remove the partitions from a particular table. The table in question has 12 partitions. Based on some initial investigation, I've come up with the following options. because the table we going to remove partition will have millions of records so on considering the db downtime we are looking for a alternative way. Is there a better way?
Copy data into another table, drop all partitions, then copy the data back into the original table
Copy data into another table, drop the original table, then rename the new table and rebuild the indexes.

I have a staging table with 70 million rows and nearly 90 columns. We just want to verify and perform some validations on the data and then move this data to final tables. There staging table has a primary key in it.
We are planning to create the final table in following ways.
1. Create n number of final tables.
2. Create n number of final tables with partitions based on the primary key value in staging table.
3. Create single final table with partition based on the primary key value staging table.
