Partition of table in ODI

Hi..friends.
can we use partition of table in ODI 11g?
please give an example with video or picture representation.
Regards
Soumya.

Its still not clear if we can load data in parallel in different partition if yes then how. Do we need to create seperate interface to load data in each partition?
Thanks

Looks like you don't have partition license or don't have a complete install of Oracle version 8.0.5. The best way to check is do a sqlplus user/passwd and look for a message that said "Production with the Partitioning and objects options" to appear before the SQL> prompt. Hope this helps....

Limit on the number of partitions a table can have

Hi,
It's been quite some time I'm thinking of a simple and the best solution to a performance issue in my application. Benefiting out of partitioning the table seems a simplest approach; it involves very minimal changes to my application code and in addition, it keeps the overall application logic 100% intact. However, at times, the number of partitions required can grow to as large as 500 thousand. I know of another application implementing as many as 50 thousand partitions for one of its tables. I'm wondering if Oracle recommends or poses any limit to a number of partitions the table can have. How does that limit, if it exists, vary if each of my table partition holds only a small amount of data; say, not more than 2 thousand records each of 1 KB size. What are the important considerations that one needs to keep in mind while creating the huge number of partitions for a table?
Any inputs on this would be a great help.
Thanks,
Aniruddh
ps: Consider Oracle releases 10g onwards.

I doubt if you are using partitioning for the right causes. Please explain how is your data structured and why you need to create so many partitions..?
when creating partition, you need to consider..
a) why you need to partition?
b) how is your data structured
c) how your data is indexed.
d) What kind of queries would you firing on this table to get the data. Will they use the partition key ?
Thanks,
Rajesh.
Please mark this/any other answer as helpful or answered if it is so. If not, provide additional details/feedback.
Always try to provide create table and insert statements to help the forum members help you better.

PL/SQL- Problem in creating a partitioned fact table using select as syntax

Hi All,
I am trying to create a clone(mdccma.fact_pax_bkng_t) of existing fact table (mdccma.fact_pax_bkng) using dynamic pl/sql. However, pl/sql anonymous block errors out with following error:
SQL> Connected.

The above pl/sql creates a DDL for partitioned fact table(new) based on an existing fact table and get executes through CLOB.
Please look into the issue and let me know any changes or modifications/suggestions that are required to fix the issue. Any help is appreciated.

Think this is your problem:
v_cmd := v_cmd||')'||' AS SELECT ' || '*'||' FROM ' || v_owner||'.'|| v_table_original ||' WHERE '||'1'||'='||'2'||';';Remove the SQL terminator ';' ... dynamic SQL doesn't require it, try this instead:

Partitioning of table in oracle 10g - How to Add

Hello Friends ,
Hope you are all fine and doing great.
By the way - I have a quick question on oracle 10g Partitioning of tables...
I have a table with partition as stated below ..
CREATE TABLE X_ACC_ASSETS_GPC_AGG
X_ACC_ASSETS_GPC_AGG_RK NUMBER(10) NOT NULL,
X_AS_OF_DT DATE NOT NULL,
ACCOUNT_RK NUMBER(10) NOT NULL,

X_AUC_AMT NUMBER(18,5),

My question is :
1) How to add a partition say P201201 ..
Since I have already stated PARTITION PMAX can I still add partition?
2) Can I add partition even though the table has data ?
==========================
I tried to add partition ..say
ALTER TABLE X_ACC ADD PARTITION P201201 VALUES LESS THAN
(TO_DATE(' 2012-01-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))

but getting the error ..

Thanks/kumar

You have partitions
200712
200812
200912
201012
201112
PMAX.
so your condition for partition p201112 is '201012-01-01' to '201112-01-01' i.e the values between these two dates will be in partition p201112. and then everything else will be in PMAX. So now you are splitting your pmax.
alter table X_acc split partition pmax at ( to_date('2012-01-01 00:00:00','YYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN') )
into (partition p201201, partition pmax); The condition you have to change. I just showed as an example. It could be the date range between two dates or it could be greater than a date value. It is upto how you want this new partition.

Sql server partition parent table and reference not partition child table

Hi,
I have two tables in SQL Server 2008 R2, Parent and Child Table.
Parent has date time, and it is partitioned monthly, there is a Child table which just refer the Parent table using Foreign key relation.
is there any problem the non-partitioned child table referring to a partitioned parent table?
Thanks,
Areef

The tables will need to be offline for the operation. "Offline" here, means that you wrap the entire operation in a transaction. Ideally, this transaction would:
1) Drop the foreign key.
2) Use ALTER TABLE SWITCH to drop the old data.
3) Use ALTER PARTITION FUNCTION to drop the old empty partition.
4) Use ALTER PARTITION FUNCTION to add a new empty partition.
5) Reapply the foreign keys WITH CHECK.
All but the last operation are metadata-only operation (provided that you do them right). To perform the last operation, SQL Server must scan the child tbale and verify that all keys are present in the parent table. This can take some time for larger tables.
During the transaction, SQL Server holds Sch-M locks on the table, which means that are entirely inaccessible, even for queries running with NOLOCK.
You avoid this the scan by applying the fkey constraint WITH NOCHECK, but this can have impact on query plans, as SQL Server will not consider the constraint as trusted.
An alternative which should not be entirely dismissed is to use partitioned
views instead. With partitioned views, the foreign keys are not an issue, because each partition is a pair of tables, with its own local fkey.
As for the second question: it appears to be completely pointless to partition the parent, but not the child table. Or does the child table only have rows for a smaller set of the rows in the parent?

Partitioning of tables in oracle 1og

I want to do the partitioning of tables due to increasing their size.Can anyone guide me cn I do it? Is it possible to do it?If possible then how can i do it.plz guide mme with al qeuries.
thanks.

While it is certainly possible to partition tables (assuming you have the enterprise edition and the partitioning option), that is not something that you would generally want to take a cookbook approach to. Partitioning tables incorrectly is a great way to slow down the system and make it oodles more difficult to support. Partitioning requires a fair amount of architecture and design to get right, and that, in turn, requires that you understand how partitioning works, how your application works, and what you want partitioning to do to change the way your application works.

Partitioning A table on a data column

Hi,
My requirement is to partition a table using a column with DATE datatype.
Example:
CREATE TABLE parttab
STATUS CHAR(1) DEFAULT 'a' NOT NULL,
UPDATER VARCHAR2(55) NOT NULL,
UPDTIME DATE DEFAULT SYSDATE NOT NULL
TABLESPACE part_tbs
Now i want to RANGE partition the above table on the "UPDTIME" column, so that it will look like:
Partition Value from Value till
P1 01-Jan 31-Mar
P2 01-Apr 30-Jun
P3 01-Jul 30-Sep
P4 MAXVALUE
I tried using the below syntax, but failed with error.
CREATE TABLE parttab
STATUS CHAR(1) DEFAULT 'a' NOT NULL,
UPDATER VARCHAR2(55) NOT NULL,
UPDTIME DATE DEFAULT SYSDATE NOT NULL
TABLESPACE part_tbs
LOGGING
PARTITION BY RANGE (UPDTIME)
PARTITION P1 VALUES LESS THAN (to_date('04','MM')) LOGGING COMPRESS TABLESPACE part_tbs_P1,
PARTITION P2 VALUES LESS THAN (to_date('07','DD-MM')) LOGGING COMPRESS TABLESPACE part_tbs_P2,
PARTITION P3 VALUES LESS THAN (to_date('10','DD-MM')) LOGGING COMPRESS TABLESPACE part_tbs_P3,
PARTITION P4 VALUES LESS THAN (MAXVALUE) LOGGING COMPRESS TABLESPACE part_tbs_P4
COMPRESS
NOCACHE
PARALLEL ( DEGREE 2 INSTANCES Default )
ROWDEPENDENCIES
NOMONITORING
ENABLE ROW MOVEMENT;
Please suggest.
Thanks in advance for the suggestions.

what is the error message and your Oracle version? this sample may assist I guess -
CREATE TABLE range_part (
prof_history_id NUMBER(10),
person_id       NUMBER(10) NOT NULL,
organization_id NUMBER(10) NOT NULL,
record_date     DATE NOT NULL,

TABLESPACE part2,
PARTITION yr2 VALUES LESS THAN (TO_DATE('01-JAN-2002','DD-MON-YYYY'))

I have partitioned my tables, do I need to rebuild the indexes of the table

Hello,

By the way, how did you partition existing tables? Did you use dbms_redefinition, or did you use CTAS, or some other method?
I love RAGE partitions. You should always always partition your rage.

How to read I$ table using ODI procedure

Hi
Can any one help me how to drop a I$ table from out sie of interface.
I have tried below approches but no luck
I have created ODI procedure with technology oracle and target logical schema (I$ tables are creating on target DB) with and with out begin and end;
Approch 1:
Given below code in ODi procedure
drop table <%=odiRef.getTable("L", "INT_NAME", "W")%> <% if (new Integer(odiRef.getOption( "COMPATIBLE" )).intValue() >= 10 ) { out.print( "purge" ); }; %>
Approch 2:
drop table I$_<%=odiRef.getTable("L", "TARG_NAME", "A") %>;
Approch 3:
drop table <%=odiRef.getTable("L", "INT_NAME", "W")%> (but it is fetching target dtabase schema anme not I$ table)
Please help me any other alternative way to drop a I$ table, more over this code should be unique for all interface

Actaul my requirement is some time my scenario is stoping due some issue at Merge Rows Step (I am using IKM Oracle Incremental Update(Merge) KM) when the next iteration starts it is thwoing and error at create flow table I$ step and error is table name is already exists, so i am doing is if the interface went failed I am storing those information in one table using ODI procedure (INF--ko-->ODI procedure) in same ODI procedure I want to call a I$ table to drop.
Can you please provide the steps so it will very useful for me using Java variable.
I have gievn a step as below on create I$ table step (after create I$ statement)
<@ java.lang.String Idollertable = <%=odiRef.getTable("L", "INT_NAME", "W")%> ; @>
I am calling Idollertable variable in ODI procedure which is ko>* of INF as <@=Idollertable@>
Note: I have followed below approch
ODI Procedure Code:
drop table <@=Idollertable@>; --> *2nd approch*
begin
insert into ODI_EXECUTION_ERROR_DETAILS
(SESSION_NO,
SCENARIO_NAME,
CONTEXT_NAME,
ERR_MESSAGE,
INSERT_COUNT,
ERROR_COUNT)
values
<%=snpRef.getSession("SESS_NO")%>,
'<%=odiRef.getPrevStepLog("STEP_NAME")%>',
'<%=odiRef.getContext( "CTX_NAME" )%>',
'<%=odiRef.getPrevStepLog("MESSAGE")%>',
'<%=odiRef.getPrevStepLog("INSERT_COUNT")%>',
'<%=odiRef.getPrevStepLog("ERROR_COUNT")%>'
commit;
drop table <@=Idollertable@>; --> * first approch *
end;
Please help me
Regards,

Why do we need Work Table in ODI???

Hello All,
Please help me on this..
Why do we need Work table in ODI???
Why ODI is creating c$_0table_name (work table)?
Thanks
Ravikiran

Hi,
this is the standard "Load Data" from LKM SQL to SQL
+<%for (int i=odiRef.getDataSetMin(); i <= odiRef.getDataSetMax(); i++){%>+
+<%=odiRef.getDataSet(i, "Operator")%>+
select     <%=odiRef.getPop("DISTINCT_ROWS")%>
+     <%=odiRef.getColList(i, "", "[EXPRESSION]\t[ALIAS_SEP] [CX_COL_NAME]", ",\n\t", "", "")%>+
from     <%=odiRef.getFrom(i)%>
where     (1=1)
+*<%=odiRef.getFilter(i)%>*+
+*<%=odiRef.getJrnFilter(i)%>*+
+<%=odiRef.getJoin(i)%>+
+<%=odiRef.getGrpBy(i)%>+
+<%=odiRef.getHaving(i)%>+
+<%}%>+
as you can see in C$_ you could have some filtered data. If you have got a source table containing invoicing (10kk rows) you could filter last_update column and obtain 1k rows for example and copy only this tiny subset.

Partitioning Fact Table

Hi
In our data warehouse we have a Fact table which has grown quite a large in size around 17 million records. We have been pondering on the options to partition this table.
Unfortunately this fact table does not have any date columns , all columns are surrogate keys of dimensions, even for time dimensions. My idea is to partition by range by manually specifying the surrogate key ranges of time dimension. Is that the way one proced with?
Other option is to, add a new column to the Fact Table and populate with the corresponding "ddmmyyyy" in number format and use that one to partition the table. If I go with this approach, if in my reports / queries if I use the dimension key to join between the Fact and Dimension, will oracle still identify which partition to look for? Or do I MUST use the partitioned column in the queries for partition pruning to be effective.
Any thoughts would be useful.
Regards
Mahesh

if in my reports / queries if I use the dimension key to join between the Fact and Dimension, will oracle still identify which partition to look for? No the oracle will not use the Partition Prunning in this case.
Or do I MUST use the partitioned column in the queries for partition pruning to be effective.yes , you need to use the partitioned column for partition pruning to be effective.

Partition of table in real life

Hi all
i have read about partition of table.
but i have lot of question in this topic.
1.which one is better
range partiting
hash "
list "
composite "
2.how we can use partition in select statment
when we don't know about the partition values.
suppose partition acc to month in table
and user enter his rollno to see its details then
how we can give details to user acc to his rollno
plz give e.g in which partiting is use
3.partition is userful in oltp system or both (oltp+dss)
4.partition gives benefit for report creation or not.
thanks all

1) If one partitioning method were better, Oracle wouldn't have all three options. Each type of partitioning is appropriate in some instances and inappropriate in others.
2) I'm really not sure what you're asking here. Can you rephrase the question? Also, can you explain the abbreviations "acc" and "rollno"?
3) Partitioning can be useful in all types of systems. Different types of systems, though, tend to be interested in different partitioning benefits. Data warehouses tend to look at partitioning as much for the managability benefits (decreasing backup times, simplifying maintenance tasks, etc) as for the performance benefits. OLTP systems are less interested in the managability benefits.
4) Partitioning may or may not speed up report creation. It depends upon the partitioning method, the data distribution, the access patterns of the report, and a number of other variables.

Should I partition a table or not???

I have a table with well over 8 million records and growing around 15,000 records daily. It is queried through a form (forms6i), no updates are done on the form just "select". The indexes are set up for the 2 types of querries mostly performed- by a date criteria and an id criteria. Is indexing good enough? I notice that it is getting harder to get results from date specific querries. What is the best approaches to ensure the table is optimized for querries? I am not used to working with such a large table size. Does partitioning help indexes work more efficient? Should I run statistics on the whole table?? I am not comfortable running statistics on the table when I am not around to monitor the performance on the server. The database runs 24 hours, 7 days a week- there is no real "downtime" to run stats.
Please advise, I would like to find a best practice approach.

(small correction in my earlier posting)
mostly performed- by a date criteria and an id criteriaPartitioning NOT always imporves performance. It can degrade performance if you had NOT partitoned based on queries those hit.
Beaware of local indexes. You might degrade performance because you may need to proble mulitple index partitions.
Do you query date and Ids by range search or exact search ?.
How much data (roughly 10% ,20% , 1% etc..) you fetch through the query
