Make partitioning an existing regular table

Hi,
I am using oracle 9i R2 on linux Red hat 4.4.My question is, I have a table in database with the name of employee
and want to make partition this table (Range Partition).Which steps should i follow to convert this regular table in range partition table.
SQL> desc employee
Name Null? Type
DATE DATE
EMPLOYEE_ID NOT NULL NUMBER(6)
LASTNAME NOT NULL VARCHAR2(25)
SALARY NOT NULL NUMBER(8,2)
Thanks.

Partition an existing table

How can I partition an existing table? What's the SQL syntax?
Thanks for help,
Chen Zhao

Does anybody know how to partition an existing table?
YES! That is the simple answer to your question. There are a lot of people that know how to do that.
Whether partitioning is appropriate and, if so, which method might be 'best' for YOU depends on the particulars of your use case. But as with most problems you need to make sure you troubleshoot whatever issue you have in the proper order:
1. Identify a PROBLEM or issue that needs to be resolved - you haven't told us anything. Please post info about this
2. Validate that the problem/issue actually exists (it could just be a fluke occurence)
3. Identify potential solutions to the problem/issue - that list of solutions may, or may not, include partitioning
4. Select a small number (e.g. 1 or 2) of those solutions for further analysis and actual tests.
5. Select the 'best' (based on your orgs criteria) of those tested solutions for implemention
You seem to already be on step #5. But in order for us to help you we have to understand what the results of steps 1 thru 4 are.
Please post the information about your PROBLEM that we need to help you.

"RUN-TIME ERROR '3078': The Microsoft Access database engine cannot find the input table or query 'name'. Make sure it exists and that its name is spelled correctly.

When I run the code below I get the following error:"RUN-TIME ERROR '3078': The Microsoft Access database engine cannot find the input table or query 'False'. Make sure it exists and that its name is spelled correctly. Note that I do not call

DoCmd.Close acForm, "MaterialLotListAvailable"
Else: MsgBox "This material lot has already been assigned to this job."
DoCmd.Close acForm, "MaterialLotListAvailable"
End If
End Function

I think the SQL statement should be
strSQL = "SELECT * FROM MaterialLotJobJoint WHERE JobID=" & _
tempvars!JobID & " AND MatLotID=" & tempvars!MatLotID
This assumes thatJobID and MatLotID are number fields.

Suggestions for table partition for existing tables.

I have a table as below. This table contains huge data. This table has so many child tables .I am planning to do a 'Reference Partitioning' for the same.

grant select, insert, update, delete on PROMOTION_DTL to SCHEMA_RW_ROLE;I would like to partition this table .Most of the queries contains the following conditions.
promo_end_date >=   SYSDATE
and
(event = :input_event OR
(:input_Start_Date <= promo_end_date
AND promo_start_date <= :input_End_Date))Any time the promotion can be closed by updating the PROMO_END_DATE.
Interval partioning on PROMO_END_DATE is not possible as PROMO_END_DATE is a nullable and updatable field.
I am now to table partition.
Any suggestions are welcome...

DO NOT POST THE SAME QUESTION IN MULTIPLE FORUMS PLEASE!

How to create a partition on existing table?

Hey
Could some one please tell me on how to create a partition on existing table?

Could some one please tell me on how to create a partition on existing table?
You can't - that isn't possible. Unless a table is already partitioned you can NOT create another partition on it.
You must either redefine the table as a partitioned table (using the DBMS_REDEFINITION package) or create a new partitioned table and move the data to its new partitions.
The choice will depend on how much data the existing table has and whether you can do it offline.

What's the best practice to partition an existing table?

We are using Oracle 11g EE 11.2.0.3.0. We want to partition an existing table. I found some information from this link [http://www.oracle-base.com/articles/misc/partitioning-an-existing-table.php], but I am not sure whether that's the best way. Could anyone share the best practice of partitioning an existing table?
Thanks.

We want to partition a few related tables. A couple of tables have about 30 million rows, and a couple of other tables have about 10 million rows. The data for those tables is for ~2000 accounts, each of them is identified by a column named "account_id". We want to partition the tables by using the "account_id" as the partition key to gain better performance for queries, so we would probably use hash partition. Please advise.
>
1. What evidence do you have that your performance will be any better if you partition those tables?
2. What evidence do you have that there is anything wrong with the performance of your current queries?
3. Have you reviewed the actual execution plans for your most important queries to see if there is even any room for improvement?
If your query uses account_id as a predicate but only pulls a few records from a 'master' table for that key value your performance may actually be worse if you partition that table. That is because using an index range scan Oracle can easily find the ROWIDs of the rows that need to be selected and then easily retrieve them regardless of their physical location.
If you have queries that do NOT use account_id but currently use indexes the performance of those queries may also be worse if you partition that table. Those indexes will be GLOBAL.
There are two major implications when you use hash partitioning:
1. Any query that does NOT include the partitioning key (account_id for your case) will, of necessity, have to use a full table scan if an appropriate index is not available.
2. You will get NO management benefits such as being able to add/remove partitions that include old data.
Before you decide to partition a table you should conduct tests and examine the execution plans for your important queries.

Partitioning an Existing Table with data

Hi All,
I am few tables with data, I need to Partition the table without affecting existing table values is it possible?.
if yes then Please suggest me some ideas to archive that..
Thanks & Regards
Sami

Hi All,
I Need to partition for existing table with 1 million records
1. First partition should be created for 6 months
2.Second partition should created for 1 year.
3.So as of now we have 6 months Data in production + another 6 months data in First partition + another 1 year data in Second partition.
4.More than 2 year’s data’s should be moved other partition or archived.
kindly provide your valuabe suggestion.

Partitioning an Existing Table

Dear Forum,
Can we create partition on an existing table without dropping it in Oracle 11.2.0.3.0?
I know EXCHANGE PARTITION, but that I don't want.
Thank you & regards.

You cannot partition an existing table.
You have to create a new partitioned table and move the data from the old table to the new table. If you want to do this online, you can potentially leverage the DBMS_REDEFINITION package to help you out. Behind the scenes, you're still creating a new table and, eventually, dropping the old table after moving all the data over. DBMS_REDEFINITION hides some of that from you and lets the table remain online while you are moving the data. But it adds some performance overhead.

Create partition to existing table

I have a existing table which is not partitioned. How can partition my existing table?

oops.... This is more better....
Partitioning an Existing Table
http://www.oracle-base.com/articles/misc/PartitioningAnExistingTable.php
Other method
(1) create new_table with oen or more range partition.
(2) alter table new_table exchange partition with old_table.
(3) rename or drop old_table.
(4) rename new_table to old_table.
(5) split or add partition.
-- Examples
--(1)
create table part_tab
partition by range (col)
(partition p1 values less than (maxvalue))

Partitioning of existing tables.. based on date

Hello Friends,
I have some tables where their is a column called x_as_of_dt COLUMN with DATE as the datatype.
All the tables have already got data populated.
Now I want to partition the tables based on column x_as_of_dt by YYYYMM
How to approach this scenario..
Appreciate your help

HOUSEHOLD_ID,
X_BRANCH_ID,

PROCESSED_DTTM
) SELECT FINANCIAL_ADVISOR_RK,
HOUSEHOLD_RK,
X_AS_OF_DATE,
FINANCIAL_ADVISOR_ID,
HOUSEHOLD_ID,
X_BRANCH_ID,
X_FA_HHD_PCT_SPLIT,
X_RANK_NUM,
PROCESSED_DTTM
FROM X_FA_X_HOUSEHOLD
Step 3: - Creating indexes
CREATE UNIQUE INDEX XPKX_FINANCIAL_ADVISOR_X_HOUSE ON PARTITION_X_FA_X_HOUSEHOLD
(FINANCIAL_ADVISOR_RK, HOUSEHOLD_RK, X_AS_OF_DATE)
Step 4: - Droping the actual table
DROP TABLE X_FA_X_HOUSEHOLD
Step 5: Renaming the partitioned table to old tablemame
ALTER TABLE PARTITION_X_FA_X_HOUSEHOLD RENAME TO X_FA_X_HOUSEHOLD
Does the above steps are correct - pls confirm.

How to change the partition type on a table with data

Hi
I have a table, which is partitioned by list on date column. The table contains large volume of data.
My requirement is to make the list partition into range on the same date column.
I am working on Oracle10g
Kindly advice

partitioned by list on date How many distinct DATE values do you have ? Each DATE value would be a Partition in List Partitioning.
Why do you need to convert this to RANGE Partitioning ? How many DATE values do you expect in the table in the future ?
You can use DBMS_REDIFINITION to copy a LIST Partitioned Table to a RANGE Partitioned Table and then switch the tables at the end.
See examples (where the source table is not partitioned)
http://www.oracle-base.com/articles/misc/partitioning-an-existing-table.php
http://uhesse.com/2010/02/15/partitioning-a-table-online-with-dbms_redefinition/
But before converting I would justify why a LIST Partitioned Table be converted to RANGE Partitioned. Do you have Date-Range queries ?

Add a new field to an existing Condition table

How can I add a new field to an existing condition table?
I have table 971 and I want to add INCOTERMS (INCO1) to this existing table but do not see how to add it.
Thanks

Hi Vicky,
I dont think you can add new fields to the condition table once you have activated the condition table.
SAP says you can only make limited changes to the condition table, like changing the description, fast entry screen, header and footer fields, but not able to add new fields to the table, and I think that is the correct approch or else for the same table you will have two sets of condition records.
Please refer to the below link:
http://help.sap.com/saphelp_erp60_sp/helpdata/en/de/7a8534c960a134e10000009b38f83b/frameset.htm
What you can do is create a new condition table with additional field and assign this table before the currently used table in the access sequence.
Hope this helps.

How to format one partition from existing filesysem

Hi All,
I want to install ASM on my RHEL machine. There is one disk which has been partitioned into regular filesystem as follows:
[root@*** /]# fdisk -l
Disk /dev/hda: 644.2 GB, 644245094400 bytes
255 heads, 63 sectors/track, 78325 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
   Device Boot      Start         End      Blocks   Id System
/dev/hda1   *           1          25      200781   83 Linux
/dev/hda2              26       57392   460800427+ 83 Linux
/dev/hda3           57393       61471    32764567+ 82 Linux swap / Solaris
/dev/hda4           61472       78325   135379755    5 Extended
/dev/hda5           61472       78325   135379723+ 83 Linux
My question is, how can I format and merge a couple of partitions from these to create a volume for ASM? Is it even possible?
Regards,
Vinod

It can be done as below:
#fdisk /dev/hda
p
--To print partitions
d
--To delete partition, chose 2[This will erase the contents in it]
n
--Create new partition
choose p to create primary partition
now /dev/hda1 can be used as ASM disk.
#chown oracle:oinstall /dev/hda1
login to ASM and update the asm_diskstring to include this disk and run "select* from v$asm_disk" we can see this new disk as CANDIDATE Or Provisioned
Thanks,

Dangerous - the default partition type of a newly created partition is ext3. Which means the kernel will view that partition as a regular file system - and will attempt to mount and use it. A sysadmin will not know, looking at the type of partition, that it is not an ext file system, but in fact a raw device.
One needs to avoid this confusion - as it easily can trash your entire database's storage (diskgroup). With the only option being to restore backups that likely is out of date, or non-existent. (given the lackadaisical attitude to use a file system partition as a raw device, it is a reasonable assumption that backups are in a similar sorry state)
PS. and the question was how to use /dev/hda2 - you described removing that partition and then using /dev/hda1 (which will likely trash the root file system).

Partition exchange error on table with nested table

On Oracle 11.2.0.1, I have a partitioned table with some partitions that need to be 'archived' (in terms of moving partitions to an 'archive' table).
I have a source table like:
CREATE TABLE IS_PODACI245

ID_OBJEKTA                 NUMBER(20),

/I would like to make exchange partition using stage table, and everything is going fine on all tables, but only on a few of them (listed source is one of them, and they're only tables with nested tables wihin), where I get an error.. but sometimes ;)
on a statement like:
ALTER TABLE IS_PODACI245_ARH EXCHANGE PARTITION P_201106 WITH TABLE IS_PODACI245_STAGE EXCLUDING INDEXES WITHOUT VALIDATION;I got an error:
ORA-00001: unique constraint (TXV.SYS_C0032911) violated
it's an unique index between parent and nested table.
what could cause that problem?

Dear,
I suppose that the unique constraint
ORA-00001: unique constraint (TXV.SYS_C0032911) violatedis the one you 've created on the nested table IS_PODACI245_STORE_TABLE
If so, why not disable that constraint and try again.
I have never exchanged such a kind of partitioned table having a nested table in it. But, I could imagine that the cloned non partitioned table IS_PODACI245_STAGE should at least be the exact image of the partitioned table IS_PODACI245_ARH (of course without the partition part) but with the nested table part and including all indexes
In addition, if you have a parent/child relationship between your partitioned tables, then there is a chronological order of exchange starting by the child and then finishing by the parent
see the following link for more information about this order of exchange (and comment 2 for an example also)
