Table partitioning and global indexing

hello all,
the requirement is to do table partitioning with global indexing! & also thr r almost 60 crores of rows are there! so can you tell me the way which can be done better and also please provide me the procedure with documents?
thanks in advance!

Hi,
have a look at online redefinition of a table, see Oracle Manual (10.2): http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/tables.htm#ADMIN01514
The steps are described in the manual.

11g interval partitioning and global index maintenance

hi gurus,
in 11g interval partitioning system can automatically manage the creation of new partitions based on data.
in this case do we need to manage global indexes?
in earlier versions, we have to update global indexes whenever there is a partition maintenance operation.
please suggest.
thanks,
charles

So it should be the same when using interval partitioning.

A question regarding database table partitioning and table indexes in 10g

We are considering partitioning a large table in our 10g database, in order to improve response time. I believe I understand the various partitioning options, but am wondering about the indexes built over the table. When the table is partitioned, will the indexes also be partitioned "automatically"? Or do I need to also partition the indexes as well?
Thank you in advance to any and all who respond to this question.

Hello,
When you build your partiton table you just need to create indexes locally and they will be partitioned automatically, see following example
CREATE TABLE YY_EVENT
PART_KEY       DATE                              NOT NULL,
SUBPART_VALUE NUMBER                             NULL,
EVENT_NAME     VARCHAR2(30 BYTE)                  NULL,
EVENT_VALUE    NUMBER                             NULL
TABLESPACE TEST_DATA
PARTITION BY RANGE (PART_KEY)
PARTITION Y_EVENT_200901 VALUES LESS THAN (TO_DATE(' 2009-02-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
    TABLESPACE TEST_DATA,
PARTITION Y_EVENT_200902 VALUES LESS THAN (TO_DATE(' 2009-03-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
    TABLESPACE TEST_DATA
-- This will create paritioned indexes automatically
CREATE INDEX MY_IDX ON YY_EVENT
(EVENT_NAME)
TABLESPACE TEST_DATA
LOGGING
LOCAL;Regards

Drop Partition update Global Indexes

hello Gurus,
what will happen internally when issue a command
alter table tab_name drop partition part_name update global indexes;
why my insert statement waiting to complete this task on " cursor: pin S wait on X "
thanks in advance ..

Several times i also noticed that wait event for some jobs on 10 2 0 4 on hpux.
I didn't found out what was the reason.
It seems this wait event can be easly related to some bugs.

Table Partitions and Rolling Window: free space not reclaimed

I have a couple of processes that involve the rolling window scenario where we drop an old partition and add a new partition monthly. We are seeing, however, that free space is not being reclaimed, and so I keep having to feed new datafiles into the tablespace (which is LMT). I was (mistakenly, it seems) under the impression that dropping a partition frees up that space for re-use.
We're currently on Oracle 10gR2 (10.2.0.2), but these tablespaces were orginally created in 9i. I've read that one solution is to implement "table shrinking," however I also see that is only available on tables in an ASSM tablespace. I see that ASSM is the default for tablespaces in 10gR2, but since my tablespaces were created in 9i, I assume they are not ASSM.
I'd like to see what other people think of this scenario. Surely a lot of people do the rolling window scenario and need space reclaimed.

No, it is of concern because Sanadra was messing with the partitions. She could have inadvertantly caused something to happen, in this case the free-space issue, and it's imperative to get all of the details.
My iMac 27' Late-2012 does not have a fusion drive, yet shows that the type is "internal" the original poster doesn't indicate that.

Creating abap program to develop and activate a global table type and global structure.

Hi friends,
I want to create and activate a global structure and global table type by coding in ABAP editor only. so can I do that anyhow.
Please help me.
Thanks in advance.

Thanks guys for your fruitful replies, as most of you asked the main purpose of my question, the answer is as follows:
in fact my purpose to do so is to create a function module that can fetch data dynamically from different database tables based on the codings in different abap program.
for example: in one abap program i am coding as follows:
tables: kna1.
types: begin of itab,
          kunnr type kna1-kunnr,
          name1 type kna1-name1,
          end of itab.
data: it_tab type standard table of itab,
         wa_tab type itab.
similarly in other program i am coding as follows:
tables: vbrp.
types: begin of itab,
          posnr type vbrp-posnr,
          matnr type vbrp-matnr,
          arktx type vbrp-arktx,
          end of itab.
data: it_tab type standard table of itab,
         wa_tab type itab.
so now for both programs i want to call the same function module and fetch data as required in relative programs as mentioned above. in that case how to create that function module?

What happens to Existing index after table partition and created with local index

Hi guys,
desc part id number, name varchar2(100), salary number
In an existing table PART i am adding 1 more column DATASEQ NUMBER. i am asked to partition the table part based on dataseq.now the table is created with this logic
create table part( id number, name varchar2(100), salary number, DATASEQ number) partition by list(dataseq) (partition PART_INITIAL values (1));
Suggestionn required. since the table is partitioned based on DATASEQ i am asked to add local index on dataseq. i have added local index to dataseq create index idx on part(dataseq) LOCAL; Now my question is already there is existing index is for the column ID and salary.
1) IDX for dataseq is created locally so that it will have partition on each partition on the main table. Please tell me what happens to the existing index on the column ID and salary.. will it again created in local?
Please suggest

Hi,
first of all, in reality "partition a table" means create a new table a migrate existing data there (although theoretically you can use dbms_redefinition to partition an existing table -- however, it's just doing the same thing behind the scenes). This means that you also get to decide what to do with the indexes -- which indexes will be local, which will be global (you can also re-evaluate some of existing indexes and decide that they're not really needed).
Second of all, the choice of partitioning key looks odd. Partitioning is a data manageability technique more than anything else, so in order to benefit from it you need to find a good partitioning key. A recently added column named "data_seq" doesn't look like a good candidate. Can you provide more details about this column and why it was chosen as a partitioning key?
I suspect that whoever suggested this partitioning scheme is making a huge mistake. A non-partitioned table is much better in all aspects (including manageability and performance) than wrongly partitioned one.
Best regards,
Nikolay

Split Oracle 11g Table Partition and Insert new rows

Hi,
I have a doubt that i would like to be clarified. I need to split a partition of a table with more than 800 Million records, but at the same time (during the split operation) i need to insert new records (not in the partition that is being splited). Is there any problem/risk doing this? Is the insert ETL process going to fail ?
Thanks in advance
Greetings.
Nuno

Hi Enrique,
Thanks for posting in MSDN.
Based on the description, you want to modify the formula for the A1 and B1 cell when you insert a new rows.
Yes, we can use Worksheet.Change to dermin the change of data on the worksheet then we can modify the formula as we wanted. Here is a sample for your reference:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Me.Range("A1").Formula = "=MAX($A2:$A" & Me.UsedRange.Rows.Count & ")"
Me.Range("B1").Formula = "=MIN($B2:$B" & Me.UsedRange.Rows.Count & ")"
End Sub

Local index vs global index in partitioned tables

Hi,
I want to know the differences between a global and a local index.
I'm working with partitioned tables about 10 millons rows and 40 partitions.
I know that when your table is partitioned and your index non-partitioned is possible that
some database operations make your index unusable and you have tu rebuid it, for example
when yo truncate a partition your global index results unusable, is there any other operation
that make the global index unusable??
I think that the advantage of a global index is that takes less space than a local and is easier to rebuild,
and the advantage of a local index is that is more effective resolving a query isn't it???
Any advice and help about local vs global index in partitioned tables will be greatly apreciatted.
Thanks in advance

here is the documentation -> http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14220/partconc.htm#sthref2570
In general, you should use global indexes for OLTP applications and local indexes for data warehousing or DSS applications. Also, whenever possible, you should try to use local indexes because they are easier to manage. When deciding what kind of partitioned index to use, you should consider the following guidelines in order:
1. If the table partitioning column is a subset of the index keys, use a local index. If this is the case, you are finished. If this is not the case, continue to guideline 2.
2. If the index is unique, use a global index. If this is the case, you are finished. If this is not the case, continue to guideline 3.
3. If your priority is manageability, use a local index. If this is the case, you are finished. If this is not the case, continue to guideline 4.
4. If the application is an OLTP one and users need quick response times, use a global index. If the application is a DSS one and users are more interested in throughput, use a local index.

Re-org oracle 11.1.0.7 partitioned and sub partitioned index not validiting

Hi,
As part of maintenance i did the following thing on the oracle 11.1.0.7 on windows (no archive log mode);
     Re-orgnaized the tables in application- data tablespace - done
     Re-orgnaized large table in SYSAUX tablespace - only one table (alter table sys.WRI$_OPTSTAT_HISTGRM_HISTORY move tablespace sysaux
alter index sys.I_WRI$_OPTSTAT_H_OBJ#_ICOL#_ST rebuild nologging;
alter index sys.I_WRI$_OPTSTAT_H_ST rebuild nologging;)
     Re-built the indexes on applicaton index tbs- done
     Re-built the partition indexes on application index tbs - done
     rebuilding of indexes in SYSAUX - done since it was invalid
     Run the analyze job –
     Re-claim the space at database level and OS level
but i have the issues of partitioned and subpartition indexes are not validating..how to validate the indexes i am using the below querires but:
ORA-14287: cannot REBUILD a partition of a Composite Range partitioned i

i am using the below sqls:
set head off
set linesize 200
select 'alter index '||index_owner||'.'||index_name||' rebuild partition '||partition_name||' ; ' from dba_ind_partitions where status <> 'VALID' and index_owner not in ('SYS','SYSTEM')
set head off
set linesize 200
select 'alter index '||index_owner||'.'||index_name||' rebuild subpartition '||subpartition_name||' ;'
from dba_ind_subpartitions
where status <> 'VALID'

Create index partition in the table partition tablespace

Hello,
I am running a custom job that
* Creates a tablespace daily
* Creates the daily table partition in the tablespace created
* Drops the tablepartition X days old
* Drops the tablespace for that partition on X+1 day.
The above job runs perfectly, but 'm having issues with managing the indexes for these partitioned tables. In the old database (10g - Single Node), all the partitions/indexes existed in one BIG tablespace and when I imported the table creation script into the new database, I modified all the table partitions & indexes to go into their respective tablespace.
Eg:
Table_name........Partition_name.....................Index_Part_name..........................Tablespace_name
============...================............====================...........=================
TABL1...................TABL1_2012_07_16............TABL1_IDX_2012_07_16............TBS_2012_07_16
TABL1...................TABL1_2012_07_15............TABL1_IDX_2012_07_15............TBS_2012_07_15
But now when the job runs, it creates the index into the default tablespace TBS_DATA.
Table_name........Partition_name.....................Index_Part_name..........................Tablespace_name
============...================.............====================...........=================
TABL1...................TABL1_2012_08_16............TABL1_IDX_2012_08_16............TBS_DATA
TABL1...................TABL1_2012_08_15............TABL1_IDX_2012_08_15............TBS_DATA
I can issue alter index rebuild to move the indexes to its default tablespace, but how can I ensure that the index gets created in its designated tablespace?
NOTE - the partition/tablespace management job that I run only creates the table partition and not the index.
The new env is a 2-Node 11gR2 RAC cluster on Linux x86_64.
Thanks in advance,
aBBy.

Excerpt from the job -
This creates the partition into the new tablespace.
v_sql_new_part := 'alter table '||tab_owner||'.'||tab_name||' add partition '||v_new_part_nm||'
values less than (to_date('''||v_new_part_dt_formatted||''',''DD-MON-YYYY'')) tablespace '||part_tbs;
execute immediate v_sql_new_part;New tablespace for new partition - because this is a 10T database and having multiple tablespaces helps with backup/recovery.
Thanks,
aBBy.

How can we use the table partitions feature and.........

Hai friends when i tried to use the bitmap indexes and table partitions feature ,
I got a message like this
'table partiotion feature not enabled'
so please tell me how can i enable those features so that i will be able to use those features..........

Partitioning and Bitmap Indexes are features of Oracle Enterprise addition. In fact, I think that Partitioning is an extra option that needs to purchased with Oracle Enterprise - it is not a default feature.
These features do not exist on Oracle Standard Edition (and likely Express Edition too).
