Replicated Partition: One to many?

I am hoping to set up a replicated partition, which will take exchange rate data from source to multiple targets.The issue is that I have multiple homes in any given target database for (eg) USD rate. ie I have tried using UDA's, but one USD tagged member in source, has multiple USD tagged members in target, hence partition doesnt verify.In short, can I map one to many, source to target in a replicated partition?Thanks in Advance

Are you mapping from one outline to many outlines by using the same member in the source outline to couple different target outlines? If your answer is yes, then yes you can do it. ---Message Posted by kmooney ??3/19/02 07:16---I am hoping to set up a replicated partition, which will take exchange rate data from source to multiple targets.The issue is that I have multiple homes in any given target database for (eg) USD rate. ie I have tried using UDA's, but one USD tagged member in source, has multiple USD tagged members in target, hence partition doesnt verify.In short, can I map one to many, source to target in a replicated partition?Thanks in Advance

Split Partition - One to Many

I have to split a single monthly partition (for month-end date) into daily partition for each day of the month. I am currently doing it one at a time, that is, by splitting one partition into two like 31st january into 31st January and 1st January. Then 31st January into 31st and 2nd January.( It is all in a loop). My question is can I one partition into more than 2 partition in one command so that they can happen in parallel.
My current process is taking 10 hours to complete ( One month data is about 30 million which is splitting into approximate 1 million rows each day).
I need to bring this time down to about couple of hours.
Ant suggestion is welcome.

Hello,
h5. Best and fast option is to create any empty table with all the required daily partition and just move data and use direct path insert.
CREATE TABLE T1

How just return one row of a one to many join..

So I have a one to many join where the SMOPERATOR table has data I need however it has a couple of rows that match the JOIN condition in there. I just need to return one row. I think this can be accomplished with a subquery in the join however have not been able to come up with the right syntax to do so.
So:
SELECT "NUMBER" as danumber,
NAME,
SMINCREQ.ASSIGNMENT,
SMOPERATOR.PRIMARY_ASSIGNMENT_GROUP,
SMOPERATOR.WDMANAGERNAME,
SMINCREQ.owner_manager_name,
SMINCREQ.subcategory, TO_DATE('01-'||TO_CHAR(open_time,'MM-YYYY'),'DD-MM-YYYY')MONTHSORT,
(CASE WHEN bc_request='f' THEN 'IAIO'
WHEN (bc_request='t' and substr(assignment,1,3)<>'MTS') THEN 'RARO'
WHEN (bc_request='t' and substr(assignment,1,3)='MTS') THEN 'M'
ELSE 'U' end) as type
from SMINCREQ
left outer join SMOPERATOR on SMINCREQ.assignment=SMOPERATOR.primary_assignment_group
WHERE SMINCREQ.owner_manager_name=:P170_SELECTION and SMOPERATOR.wdmanagername=:P170_SELECTION
AND open_time BETWEEN to_date(:P170_SDATEB,'DD-MON-YYYY') AND to_date(:P170_EDATEB,'DD-MON-YYYY')
AND
(bc_request='f' and subcategory='ACTIVATION' and related_record<>'t')
OR
(bc_request='f' and subcategory<>'ACTIVATION')
OR
(bc_request='t' and substr(assignment,1,3)<>'MTS')
order by OPEN_TIMe

Hi,
This sounds like a Top-N Query , where you pick N items (N=1 in this case) off the top of an orderded list. I think you want a separate ordered list for each assignment; the analytic ROW_NUMBER function does that easily.
Since you didn't post CREATE TABLE and INSERT statements for your sample data, I'll use tables from the scott schema to show how this is done.
Say you have a query like this:
SELECT d.dname
, e.empno, e.ename, e.job, e.sal
FROM scott.dept d
JOIN scott.emp e ON d.deptno = e.deptno
ORDER BY dname
;which produces this output:
DNAME EMPNO ENAME JOB SAL
ACCOUNTING 7934 MILLER CLERK 1300
ACCOUNTING 7839 KING PRESIDENT 5000
ACCOUNTING 7782 CLARK MANAGER 2450
RESEARCH 7876 ADAMS CLERK 1100
RESEARCH 7902 FORD ANALYST 3000
RESEARCH 7566 JONES MANAGER 2975
RESEARCH 7369 SMITH CLERK 800
RESEARCH 7788 SCOTT ANALYST 3000
SALES 7521 WARD SALESMAN 1250
SALES 7844 TURNER SALESMAN 1500
SALES 7499 ALLEN SALESMAN 1600
SALES 7900 JAMES CLERK 950
SALES 7698 BLAKE MANAGER 2850
SALES 7654 MARTIN SALESMAN 1250Now say you want to change the query so that it only returns one row per department, like this:
DNAME EMPNO ENAME JOB SAL
ACCOUNTING 7782 CLARK MANAGER 2450
RESEARCH 7876 ADAMS CLERK 1100
SALES 7499 ALLEN SALESMAN 1600where the empno, ename, job and sal columns on each row of output are all taken from the same row of scott.emp, though it doesn't really matter which row that is.
One way to do it is to use the analytic ROW_NUMBER function to assign a sequence of unique numbers (1, 2, 3, ...) to all the rows in each department. Since each sequence startw with 1, and the numbers are unique within a department, there will be exactly one row per departement that was assigned the numebr 1, and we''ll display that row.
Here's how to code that:
WITH got_r_num AS
 SELECT d.dname
 , e.empno, e.ename, e.job, e.sal
 , ROW_NUMBER () OVER ( PARTITION BY d.dname
 ORDER BY e.ename
 ) AS r_num
 FROM scott.dept d
 JOIN scott.emp e ON d.deptno = e.deptno
SELECT dname
, empno, ename, job, sal
FROM got_r_num
WHERE r_num = 1
ORDER BY dname
;Notice that he sub-query got_r_num is almost the same as the original query; only it has one additional column, r_num, in the SELECT clause, and the sub-qeury does not have an ORDER BY clause. (Sub-queries almost never have an ORDER BY clause.)
The ROW_NUMBER function must have an ORDER BY clause. In this example, I used "ORDER BY ename", meaning that, within each department, the row with the first ename (in sort order) will get r_num=1. You can use any column, or expression, or expressions in the ORDER BY clause. You muight as well use something consistent and predictable, like ename, but if you really wanted arbitrary numbering you could use a constant in the analytic ORDER BY clause, e.g. "ORDER BY NULL".

Replicated Partition-Cell Count not matching, what to do with Mappings tab

Hi All
I am creating a Replicated partition between 2 cubes on 9.3.1. The source cube has 8 dimensions(Cube A) and the target cube has 7 dimensions(Cube B).
2 Dimensions in cube A dont exist in Cube B and 1 Dimension in Cube B doesnt exist in Cube A.
6 of the dimensions map directly.
How do i deal with the 2 Dimensions in cube A that dont match cube B? At the moment I have mapped them to (void) in the mappings tab, by just selecting the dimension name and putting void in the target.
Cube B has dimension called SBU. All data from Cube A needs to go against member SBU Input in Cube B. I am stuck as to how to do this?
Cheers
Simon
Edited by: SimonWatts on Oct 16, 2008 4:23 PM

I believe the only issue that is likely to be wrong is the need to select a single member in the dimensions that you are eliminating (through a mapping to void). The 2 dims that exist in cube A should be selected as a single member for each, and mapped to void. If you selected the entire dimension in the partition, and only mapped the root to void, you would have a mismatched cell count.
So, change the partition spec to use a single member in those dimensions (if needed), and make sure that the member you select is mapped to void, which is not necessarilly the dimension itself.
Then, you do a similar void mapping to the SBU Input member, "Void = "SBU Input"". That handles the new cell count aspect if the other dimensions line up.
In total, there are three mappings identified from this. Two map source members to void, and one to map a target member to void.

Replicated partition is taking a long time

I have been using a replicated partition to move some data from one Database to another and it has been working working fine.
All of a sudden the replicated partition is taking a long time ( does not complete) when I run a maxl script to refresh the replicated partition. I can't seem to figure out what caused the issue. I made sure the there are no virtual members defined in the sparse dimensions and the mapping are correct.
Any idea of why the process will take so long all of a sudden?

I have narrowed down to the problem on part of the hierarchy of the dimension. The parent member has about 2500 children under it and any time we include this part of the tree in the partition the partition takes a long time( the total number of members in the Cost center is 18K)

Problem with replicated partitioning between two BSO db's. version 9.3.0.1

Hi there,
I have a problem with partitioning between two BSO db’s.
I created the partition, it validates and I made an export for the partion definiton(xml file).
Everything is fine if I set this partition up as transparent partition.
This means I can see the data from the src in the trg db as ecpected.
But when I change over to replicated (what in fact I want to do) nothing happens for the trg site - there are still no data. (Yes I have choosen Update all cells.)
I got no error in any way neither AAS nor in the app logs of src and trg.
(Mayby this it important: one src-dimension is mapped to void for the trg.)
Can anyone give me a hint or even confirm this behaviour ?
Thank you in advance
Andre

It sounds like you are doing it all correctly. One thing you might try just to be sure you are not getting any data in the target database is the following:
1) clear the target database
2) Run the replication for all cells
3) Run an export of all data on the target database
See if you get anything in the export file, maybe you are getting some of the data or possibly it is a rollup issue. Just a thought.

Performance tips on transparent and replicated partitions?

I am quite new to this partitioning scene. Does anybody has tips on how to improve the performance and create the most feasible tranparent and replicated partitions? Thanks.

Our design is triangle shaped structure. There is a main application getting fed from two sub applications and these two sub applications are connected also by a transparent partition. One of the sub applications is the same as the main application. Same number of dimensions with the same dimensions. The second sub application is a smaller subset of the main application with less dimensions. All the transparent partitions defined as "(@IDESCENDENTS("Managerial Statement of Operations") @IDESCENDENTS("Income Statement Ratios") @IDESCENDENTS("Operating Ratios") @IDESCENDENTS("Statistics")@IDESCENDENTS("System Administration")) @IDESCENDENTS("Time") @IDESCENDENTS("Income Statement Type") @IDESCENDENTS("Funding Type") @IDESCENDENTS("Network Indicator") @IDESCENDENTS("Product") @IDESCENDENTS("Market Segment") @IDESCENDENTS("State") @IDESCENDENTS("Scenario") @IDESCENDENTS("Trading Partner") @IDESCENDENTS("Organization")" at the source and "(@IDESCENDENTS("Managerial Statement of Operations") @IDESCENDENTS("Income Statement Ratios") @IDESCENDENTS("Operating Ratios") @IDESCENDENTS("Statistics")@DESCENDENTS("System Admin - PL")) @IDESCENDENTS("Time") @IDESCENDENTS("Income Statement Type") @IDESCENDENTS("Funding Type") @IDESCENDENTS("Network Indicator") @IDESCENDENTS("Product") @IDESCENDENTS("Market Segment") @IDESCENDENTS("State") @IDESCENDENTS("Scenario") @IDESCENDENTS("Trading Partner") @IDESCENDENTS("Organization")" at the target. The dimensions are "Account", "Time", "Scenario", "Market Segment", "Income Statement Type", "Funding Type", "Product", "State", "Organization", "Trading Partner", and "Network Indicator". Thanks.

One to many relationship question.

Let's say we have table1 and table2
Table1 has ID, and let's say Name for fields.
Table2 has ID, and let's say SSN for fields.
This is not so, but illustrates my points well.
Table2 has many records with the same ID, who just happen to have the same SSN. That would usually be a logical conclusion.
Table1 has only 1 of each ID in it. So you might say that ID is a foreign key in table2, except one problem. I don't think they know what primary keys are here, much less foreign keys.
Anyway, I have to write a query where I get the ID from table1 and need the SSN from table2. That's the only place in this scenario that SSN is.
My question is this - since this is a one to many relationship, yet I only need 1 result, how would I write this using the (+) way of notation? I am using 8i.
Right now, I am doing something like this, using a DISTINCT:
Select DISTINCT t1.ID, t1.Name, t2.SSN
From table1, table2,
Where t1.ID = t2.ID (+);
First of all, is this the correct way of writing it?
And second, I am wondering if, perchance for some error, there were 2 or more SSNs in table2, what would happen then? Would I get a too many rows error?
And if so, how can I trap it and possibly get just the first occurrence of it?
Is that even a sound way of doing it?
Thanks for any thoughts here.

You would need to turn your table2 into an in-line view in order to outer join to it properly. Minimally, something like:
SELECT t1.id, t1.name, t2.ssn
FROM table1 t1,
     (SELECT DISTINCT id, ssn
      FROM table2) t2
WHERE t1.id = t2.id(+)If there may be multiple ssn in t2 for a single id, you will need to determine which one you want to keep and use something like:
SELECT t1.id, t1.name, t2.ssn
FROM table1 t1,
     (SELECT id, ssn
      FROM (SELECT id, ssn,
                   ROW_NUMBER() OVER (PARTITION BY id,
                                      ORDER BY column_that_makes_it_first) rn
            FROM table2)
      WHERE rn = 1) t2
WHERE t1.id = t2.id(+)This should work on 8.1.7.4 Enterprise Edition. If you have a different version, then the analytic function may not work so you would need something more like:
SELECT t1.id, t1.name, t2.ssn
FROM table1 t1,
     (SELECT id, ssn
      FROM (SELECT id, ssn, rownum rn
            FROM (SELECT id, ssn,
                  FROM table2
                  ORDER BY id, column_that_makes_it_first))
      WHERE rn = 1) t2HTH

Difference between transparent and replicated partitions

whats the difference between transparent and replicated partitions in EAL. currently we have created essbase cube via transparent partition in eal. performance of obiee reports on essbase cube is very bad. now somebody suggested to create essbase cube via replicated partition in EAL. what difference would it make. one guy said replicated partition would make it more slow. i am confused. please explain.

Transparent Partition does not occupy or create extra memory Space in the Destination Application , it just shows the Data from Source to the Destination cube . This partition is completely dependent on Existence of Source Data . While , in replicated Partition you can use a copy of source data in the Destination cube.

Replicated Partition Hangs

I have created a replicated partition and everything validatescorrectly. When I attempt to replicate across the partitionit seems to be working but its just hanging. There is an .indfile created immediately in the new db but no page files. After a few minutes I kill the request and a page filesuddenly appears and the data in the cube exists like I wouldexpect it to. Anyone have any idea whats going on?

I looked up the error message codes and found that 1130203 seems to be the key. <blockquote>quote: <hr>1130203 Possible Problems Analytic Services is unable to allocate memory. Possible Solutions Try any of the following suggestions to fix the problem. Once you fix the problem, check to see if the database is corrupt. Check the physical memory on the server computer. In a Windows environment, 64 MB is the suggested minimum for one database. In a UNIX environment, 128 MB is the suggested minimum for one database. If the error keeps occuring, add more memory to the server computer. If you are on a UNIX computer, check the user limit profile. Check the block size of the database. If necessary, reduce the block size. Check the data cache and data file cache setting. If necessary, decrease the data cache and data file cache sizes. Make sure that the Analytic Services computer has enough resources. Consult the Analytic Services Installation Guide for a list of system requirements. If a resource-intensive application, such as a relational database, is running on the same computer, the resource-intensive application may be using the resources that Analytic Services needs. See Also 1006006 1006010 1006015 1006023 <hr></blockquote> It looks like you may be requiring more memory than might be available. This is the same sort of error that you see when you find dynamic calcs needing more calc lock block space, a problem normally resolved by increasing the data cache. It may be that the sparse-dense arrangements of your source and target databases are organized in such a way that you need to have multiple blocks cached for each during the replication. Without seeing the outlines and partition definitions, this is a best guess. I don't know whther the order of dimensions in the partition definition makes any difference, but different organizations can cause memory allocation problems, especially if the server is running at full load. You might see if there is any difference when replicating during a slow use time. Check to see that all inactive applications are stopped. That may help memory allocation. If you have a separate test server, you may want to play a bit with settings. Otherwise, try monitoring memory use on the server when doing the partition.

Replicated Partition Question

With a replicated partition is it possible to have the source area be the same and send it to 2 different targets in the same database.
here is what i am trying to accomplish
Source A
@DESCENDANTS("GM",0),@DESCENDANTS("SECURED",0),"OCT","NOV","DEC",@DESCENDANTS("CUSTOM1",0),@DESCENDANTS("CUSTOM2",0),@DESCENDANTS("CUSTOM3",0),@DESCENDANTS("ICP",0),"2014","Version4","OUTLOOK","Local",@DESCENDANTS("SVCNA",0)
Target A
@DESCENDANTS("GM",0),@DESCENDANTS("SECURED",0),"OCT","NOV","DEC",@DESCENDANTS("CUSTOM1",0),@DESCENDANTS("CUSTOM2",0),@DESCENDANTS("CUSTOM3",0),@DESCENDANTS("ICP",0),"2014","MONTH1","OUTLOOK","Local",@DESCENDANTS("SVCNA",0)
MAP A
"VERSION4" to "MONTH1"
Source B (same as A)
@DESCENDANTS("GM",0),@DESCENDANTS("SECURED",0),"OCT","NOV","DEC",@DESCENDANTS("CUSTOM1",0),@DESCENDANTS("CUSTOM2",0),@DESCENDANTS("CUSTOM3",0),@DESCENDANTS("ICP",0),"2014","Version4","OUTLOOK","Local",@DESCENDANTS("SVCNA",0)
Target B
@DESCENDANTS("GM",0),@DESCENDANTS("SECURED",0),"OCT","NOV","DEC",@DESCENDANTS("CUSTOM1",0),@DESCENDANTS("CUSTOM2",0),@DESCENDANTS("CUSTOM3",0),@DESCENDANTS("ICP",0),"2014","MONTH1","ROLLING3MTH","Local",@DESCENDANTS("SVCNA",0)
MAP B
"VERSION4" to "MONTH1"
"OUTLOOK" to "ROLLING3MTH"
Tried setting this up and it doesnt work
Thinking I need a maxl to create partition, replicate drop it create a second partition, replicate, and drop it.
Any thoughts
Thanks

They are.
Version Dimension is Version1-5 in one app and Month1, Month2, and Month3 in the other app.
Scenario Dimension is Outlook in one app and Outlook AND ROLLING3MTH in the other.
Another thing is I can get the replicated partition to refresh the data. But if I have the map for OUTLOOK to ROLLING3MTH it only pushes to ROLLING3MTH. If I leave out the map it only goes to OUTLOOK in Target.

Replicated partition Refresh

Hi All,
We have replicated partition from Cube03 to Cube01.. We refresh the replicated partition data daily using a MAXL Script.
In Cube03 the data in INtersection01 is copied to Intersection02 at the end of budget cycle.......and the data in INtersectiono1 is deleted...and We refresh the replicated partition to get data to Cube01 for these new intersections....
Since we have been refreshing the data in INtersectiono1 to Cube01....Is it stored in Cube01...Do we need to delete this data in Cube01 for INtersectiono1 ...so that ONLY the new intersection data Intersection02 is reflected in Cube01
Appreciate your respone........

Hi,
The partition exists but it has been created within EAS where the server added is the cluster as opposed to the actual server name essbase is on - EssbaseCluster-1 - So this is what it has for the Essbase Server for the Data Source and Data Target. When we try and create a partition with using the actual server name it orphans (I have another thread about that one)
Here is the output from the MAXL that I executed when trying the server name:

Replicated Partitions

I have strange behavior with my replicated partitions. When my application
starts up I always get N+1 replicants. For example, if I specify 3
replicants, Econsole starts up 4 active partitions. Even more bizzare is
that it also starts up 2 active router partitions... If I manually
shutdown the extra partitions my application DOES NOT get DEGRADED
indicating that it truly knows the number of replicants that SHOULD be
there.
Anyone have any similar experiences, solutions or ideas for this problem???

try turning off autostart temporarily and see if the behavior
persists
is it possible that one of your other partitions makes a call
to your replicated partition prior to the replicated partition's
startup?

Debug level Hibernate log excerpt:
Included in the above description.

That's not the right mapping for the 1:m relationship in Hibernate.
First of all, I believe the recommendation is to have a separate .hbm.xml file for each class, so you should have one for Parent and Child.
Second, you'll find the proper syntax for a one-to-many relationship here:
