Oracles table Partitions

I have to create an app that front ends a database of network
events. Users access this by time parameters. I take those
parameters and determine the correct oracle partition to go to (for
query speed purposes)., There are about 20 million rows in this
database. I cant do anything without being able to specify
partition. CF does not seem to work with the following:
select *
from reporting_db partition (p200901)
It does not seem to recognize "partition" as a keyword. And I
need it to recognize the entire "partition (p200901)" as valid
oracle sql. What am I missing?

Well I guess I'm too tired or something. Its working now. It
was not working from the flex cf wizard query dialog. But maybe I'm
just working to many hours and it would have worked there too. Oh
well.

Introduction of Oracle Table Partitions into PeopleSoft HRMS environment

I would like to pose a general question and see if anyone has found any published advice / suggestions from PeopleSoft or Oracle on this. I believe that Oracle table partitioning isn't supported through the PeopleTools application designer functionality. Most likely this is done for platform independence. However, we were thinking about implementing table partitioning for performance and the ability to refresh test instances with subsets worth of data instead of the entire database.
I know that this would be a substantial effort, but was wondering if anyone had any documentation on this type of implemention. I've read some articles from David Kurtz on the subject, and it sounds like these were all custom jobs for each individual client. Was looking for something more generic on this practice from PeopleSoft or Oracle...
Regards,
Jay

Thanks for the article Nicolas. I will add that to my collection, good reference piece.
I think you gasped the gist of the query, which was I know that putting partitioning into a PeopleSoft application is going to be highly specific to the client and application that you are running. But what I looking for was something like a baseline guide for implementing partitioning in a PeopleSoft application as a whole.
In other words, something like notifiaction that the application designer panels would be affected since they don't have the ability to manage partitions. Therefore, any changes to tables that would utilize partitioning would need to be maintained at the database level and no longer utilize the DDL generated from PeopleTools Application Designer. Other consideration would be, like maybe a list of tables that would be candidates for partitioning based on the application, in my case HRMS. And maybe, suggestions on what column should be used for partitioning, etc...All of which are touched on in your identified article about putting partitioning in at the database level for a generic application.
Thanks for your help, it is much appreciated...

Oracle Tables Partitioning

I am planning for table partitioning of existing tables...
database is production 10gR1 i need it to upgrade to 11gR2 and also implement table partitioning. what should be the best way to do so with minimum downtime and zero data loss. Please advice. size of the tables are 20 to 40GB.. source database is in solaris and planning to migrate on linux.

my question is for partitioning with minimum downtime with zero data loss.
the scenario is like
I took a export of source table and create a new partitioned table with different name, then import the data into new table, drop the source table and rename the new partitioned table with the source tables's name. Its all fine because there will be very minimum downtime but here we will loss some data. It is because the transactions which are done in the mean time will not be in the exported file. Is there any way another..? I hope you got my question.

Use of Logical Partition in a Oracle Table...

What is the use of Logical Partition in a Oracle Table as Target. Techincal Manual does not say any significance.
My question is:
If the Table has no partitions and if we add Logical Partitions using Data Service, what purpose will it serve?
We are planning to load 30 Million records a day into a Oracle Table. As of now the Target table has no partition and we are planning to have that soon. Is there a better way to load the data into Target Table, using Partition, Bulk Loading(API), Degree of Parallelism, etc., We have not dealt data of that volume, inputs are highly appreciated.
Regards.
Santosh.

Initial Value:
Indicator that NOT NULL is forced for this field
Use
Select this flag if a field to be inserted in the database is to be filled with initial values. The initial value used depends on the data type of the field.
Please note that fields in the database for which the this flag is not set can also be filled with initial values.
When you create a table, all fields of the table can be defined as NOT NULL and filled with an initial value. The same applies when converting the table. Only when new fields are added or inserted, are these filled with initial values. An exception is key fields. These are always filled automatically with initial values.
Restrictions and notes:
The initial value cannot be set for fields of data types LCHR, LRAW, and RAW. If the field length is greater than 32, the initial flag cannot be set for fields of data type NUMC.
If a new field is inserted in the table and the initial flag is set, the complete table is scanned on activation and an UPDATE is made to the new field. This can be very time-consuming.
If the initial flag is set for an included structure, this means that the attributes from the structure are transferred. That is, exactly those fields which are marked as initial in the definition have this attribute in the table as well.
hope it helps,
Saipriya

What Oracle Table contains Partition Key Field Name?

What Oracle table/view maintains the partition key field name?
All_Tab_Partitions does not appear to maintain such information.
When I use Toad -> Schema -> Tables -> Partitions, it lists the partition key field name that the partition is based.
Thank You

Automatic table partitioning in Oracle 11g

Hi All,
I need to implement automatic table partitioning in Oracle 11g version, but partitioning interval should be on daily basis(For every day).
I was able to perform this for Monthly and Yearly but not on daily basis.
create table part
(a date)PARTITION BY RANGE (a)
INTERVAL (NUMTOYMINTERVAL(1,'*MONTH*'))
(partition p1 values less than (TO_DATE('01-NOV-2007','DD-MON-YYYY'))
Table created
create table part
(a date)PARTITION BY RANGE (a)
INTERVAL (NUMTOYMINTERVAL(1,'*YEAR*'))
(partition p1 values less than (TO_DATE('01-NOV-2007','DD-MON-YYYY'))
Table createdBut if i use DD or DAY instead of YEAR or MONTH it fails......Please suggest me how to perform this on daily basis.
SQL>
1 create table part
2 (a date)PARTITION BY RANGE (a)
3 INTERVAL (NUMTOYMINTERVAL(1,'*DAY*'))
4 (partition p1 values less than (TO_DATE('01-NOV-2007','DD-MON-YYYY'))
5* )
SQL> /
INTERVAL (NUMTOYMINTERVAL(1,'DAY'))
ERROR at line 3:
ORA-14752: Interval expression is not a constant of the correct type
SQL> create table part

); 2 3 4 5
INTERVAL (NUMTOYMINTERVAL(1,'DD'))
ERROR at line 3:
ORA-14752: Interval expression is not a constant of the correct typePlease suggest me to resolve this ORA-14752 error for using DAY or DD or HH24
-Yasser

Yes, for differenct partitions for different months.
interval (numtoyminterval(1,'MONTH'))
store in (TS1,TS2,TS3)
This code will store data in partitions in tablespaces TS1, TS2, and TS3 in a round robin manner.
for Day wise day yes you can store
INTERVAL (NUMTODSINTERVAL(1,'day')) or
INTERVAL (NUMTODSINTERVAL(2,'day')) or
INTERVAL (NUMTODSINTERVAL(3,'day')) or
INTERVAL (NUMTODSINTERVAL(4,'day')) or
INTERVAL (NUMTODSINTERVAL(5,'day')) or
INTERVAL (NUMTODSINTERVAL(n,'day'))

Table Partition on daily basis in oracle 10g

I Want to create partition based on sysdate on daily basis.
There will be 8 partitions. Every day data's will be get loaded into this table and everyday 8th day old data ill be get truncated.

    PARTITION DAY8 VALUES LESS THAN (TO_NUBER(TO_CHAR(TRUNC(SYSDATE-7)),'DD'))
THIS WONT WORKS OUT. SO PLEASE SUGGEST ME WITH BETTER SOLUTION.

Table Partitioning in Oracle 9i

Hi all,
I have a question on partitioning in Oracle 9i.
I have a parent table with primary key A1 and attribute A2. A2 is not a primary key but I would to create partition for the table based on this attribute. I have a child table with attribute B1 being a foreign key to A1.
I wish to perform a data purging on the parent and child table. I'll purge the parent table based on A2, but for the child table, it will be inefficient if I delete all records in child table where parent.A1 = child.B1. Should I add a new attribute A2 to the child table, partition the child table based on this attribute or is there a better way to do it?
Thanks in advance for all replies.
Cheers,
Bernard

Bernard
Right 100K in the parent...but how many in the child ?
I guess it comes back to what I said earlier...you can either take the hit on the cascaded delete to get out the records on the child table or you can denormalise the column down onto the child table in order to partition by it.
I'm building a Data Warehouse currently and we're using the denormalise approach on a couple of tables in order to allow them to be equipartitioned and enable easier partition management and DML operations as you've indicated....but our tables have 100's of millions of rows in them so we really need to do that for manageability.
100K records in the parent - provided the ratio to the child is not such that on average each deleted parent has 100's of children is probably not too onerous, especially for a monthly batch process - the question there would be how much time do you have to do this at the end of the month ? I'd probably suggest you set up a quick test and benchmark it with say 10K records as a representative sample (can do all 100K if you have time/space) - then assess that load/time against your month end window....if its reasonably quick then no need to compromise your design.
You should also consider whether the 100K is going to remain consistent over time or is it going to grow rapidly in which that would sway you towards adding the denormalisation for partitioning approach at the outset.

Table partitioning (intervel partitioning) on existing tables in oracle 11g

Hi i'm newbie to table partitioning. I'm using 11g. I have table of size 32 gb (which has 22 million records) and i want to apply interval partition on that table. I created a empty table with a partition having columns same as source table and take dump of the source table and import into the new partition table. can you please suggest how to import table dump into new table? also is there any other better idea to do the same.

Hi,
imp user/password file=exp.dmp ignore=y
The ignore=y causes the import to skip the table creation and continues to load all rows.
On the other hand, you can insert data into the partitioned table with a subquery from the non-partitioned table such as follows;
insert into patitioned_table
select * from original_table;
Hope it helps,

Hi,
I found the problem.It was because of the connection string.The format was different for oracle tables.
PFB the format
*cnss.open"Provider=OraOLEDB.Oracle.1;Data Source= servername:port/SID;Database= DB;User Id=aaaa;Password=aaaa;"*
And thanks *SH* for quick response.

Oracle Table Recomendations

Hello All,
We have source data for prepaid system like voice calls, sms etc.
Oracle database 10G is our target database.
Average number of records for voice is 20 million and sms is having 10 million records per day.
We have two options for loading data in oracle tables.
1. Load the source data into separate tables like voice calls data into voice_calls partitioned(call_date)
and sms data into sms_data table (also partitioned on date).
2. Second way is that we load all calculated columns into one table.
Columns like call_type(voice/sms),mobile_number,call_date,duration,balance_used etc
Partition the table based on call_type and sub partitioned on call_date column
And (if possible) further sub partition on call_dir i.e either incomingcall/outgoingcall
And place the remaining columns from source data (which are not required for analysis) into separate tables.
Benefit of adopting the second technique is that during analysis of revenue, we can get all information from one table and we don’t need to join multiple tables.
Now my questions are:
Is it feasible to create the calculated columns table having data from different sources as its size will increase apx 10GB per day or it is recommended to create different calculated tables?
Which method will give us performance and retrieval benefits?
Any performance issue while inserting/selecting data from such fact table with large data volume and sub partitions?
Any problem during analyzing of such table?
Thanks

hi~
1. tablespace coalesce(공간 병합) 을 권장합니다.
2. index rebuild : 이것은 Table에 Index가 걸려있는 상황에서 DML이 자주 발생하면 delete marking된 index entry가 많아지는데 이것을 제거하여 공간 및 검색 효율을 향상시킬수 있습니다.
