Disadvantages of letting FACTFINANCE table grow bigger day by day?

Hi All,
Please share your inputs on the Disadvantages and Advantages of letting FACTFINANCE table grow bigger day by day.
As far as i know there's no theoretical limit to the number of records.
If there is any solution or process followed to keep only actively used data records in FACTFINANCE and smart way in dealing with very rarely used data (Historical data).
Please suggest/comment it will greatly help us!
Regards,
Rajesh Muppala.

The main disadvantage of a huge factfinance table will be initially the process time of changing a dimension hierarchy. I have heard of processing taking 8 hours when a large fact table is involved. I am not sure of a theoretical limit. I suspect the limit will be more of the operating system limits rather than SQL server limits.
Of course performance will slow when the fact table gets large to. So archiving off historic ( and not used) data is a good idea.
To create a system where only actively used records are kept would need to be a custom procedure where you;d need to analyse the queries coming from the client side. It seems a very complex method that could land up with errors and dad corruption.
I personally would rather make a business decision about it and archive a few years off into a separate application set. In an ideal world, it could be on a separate server as well so the productions system is not affected in any way.
Another option would be to make custom partitions in the finance cube. This would mean the same fact table is used but different partitions for each year (for example).

How to track which segments are growing day by day????

I have my Index tablespace which is getiing full day by day.
I am doing analysis every day.
Right now 4700MB is free.
I am checking every day by how increase is there.
some day its 40MB and some day its 112Mb.
Right now its 91% full and 9% free.
My analysis is that My tablespace will get full in around next 30 days.
I have searched for segemnts in that tablespace and found that all are indexes and some of the tables are also placed in this tablespace....
My question is:
every day that tablespace increase by 100Mb . Is ther way to find which particular segment in that tablespace is growing day by day ,My belief is one of the tables that is mistakely palced in index tablespace.
How can I achieve what I want??
Thanks

You could record the size of the segments of the given tablespace every day: create table t as select * from dba_segments where tablespace_name = &tsname
; And then on the day after that you would query something like: select s.segment_name,
          s.bytes-t.bytes segment_growth
   from dba_segments s, t
where s.tablespace_name = &tsname
    and s.tablespace_name = t.tablespace_name
    and s.segment_name = t.segment_name
; And then truncate table t and populate it with current data and repeat next day.

Importing data from an old backup AppSet (copying from FactFinance tables)

Hello - we made a mistake a few weeks ago that wiped out some of our old data. Without realizing the implications, I made a base-level member of our DEPARTMENT dimension a parent, so BPC wiped out all the data for that base-level member. We know not to do that now, and we've changed the member back to base-level. But, our data is still gone.
But, our system automatically makes a backup every day, so we have the data saved. I am now trying to get the old data into our current AppSet. One of our DBA's queried the FactFinance table and found 30,000 records where the department = the one we accidentally erased. This sounded like the correct # of records, so I had him send me the data in a .csv file. I have now verified that all of the data is there in the backup. The DBA copied the records from the the FactFinance table to a test environment of our current AppSet. But, when I go in to look at it, very few records are there. For example, he says he copied 30,000 records, but I only see about 2,000 when I query the AppSet. If it matters, the records that we see only relate to the last three fiscal years, and none of the older data is there.
Can someone tell me how we can get all of these records to appear in our AppSet by copying them to the tables? Or, is there a way to import the data using the Data Manager? I tried saving the records as a .txt file and importing them, but that did not work, probably due to my lack of knowledge of how to manipulate transformation files. Although the file did validate with a transformation file, when I went to import it, it said "Convert Data: Success", but then said "The number of failing rows exceeds the maximum specified".

If you did a backup of your appset then you will be ablle to recuperate all data for that member of dimension.
1. First extract the data from backup from follow tables:
tblfact"yourapplication"
tblfac2"yourapplication"
tblfactwb"yourapplication".
2. Make sure your member is right now base member into your application
3. Delete all the existing records for Department member for all three table
fact,fac2, wb of your current database. By the way if this dimension is share then you will have this problem in all application not just in one.
4. Copy extracted records into tblfac2"yourapplication"
5. Process from SSAS fac2 partition of your application.
After that you should be able to see all data except the data inserted after your change from base member to parent.

Writing to BLOB gets slow as table grows

Hi,
We have a table with a BLOB column. When the table is empty it takes a few second to insert 3k rows. As the table grows to 500k rows, it takes almost 5 minutes to insert the same # of rows, and it's getting slower and slower. At the beginning, I thought it was because of indexes and constraints, so I disabled all foreign key constraints (have to leave primary keys and indexes there), it doesn't make much difference. I don't see other tables with indexes and constraints and even more # of rows but w/o BLOB column have such significant performance degradation. The BLOB is stored out of line in a separate tablespace with 8k block size and chunk size.
Do you have any idea what may cause the slowness in insert?
Thanks.

If the tablespace is ASSM (segment space management AUTO), there are issues with LOB performance. If you can, move the table and it's LOB to an MSSM tablespace and re-test your inserts.
BTW, what version and patchlevel are your running ?

Black Line going through middle of screen, getting bigger by the day.

Hi,
I was wondering if you would be able to help me fix this problem.
My HP Omni 120-1034 Desktop PC was working fine until 2 weeks ago when a thin lack line appeared through the middle of the screen going horizontally. It is getting darker and bigger as the days go. I just re-installed the Graphics Driver but that is not helping.
please help. Thanks

That sounds like the display panel which, as you might imagine, is hard to get at on an all-in-one. To be sure, on a laptop we would connect it to an external monitor but yours does not have an external monitor port. Replacement screens are about $130 on eBay.

Table grows to 6 GB with 6k records only after Delete ORA-01653:

Hello,
I have a Table that i delete data from using
DELETE FROM DJ_20255_OUTPUT a where trunc(a.LOADED_DATE) <trunc(sysdate -7);
COMMIT;
the issue i have is when i want to repopulate the table i get the Error ORA-01653: unable to extend table.
The table grows to over 6gb but if i truncate that table and in both cases there is no data left in the table after either action the table will only grow to 0.8 Mb once populated.
so with truncate table size is 0.8MB and if i use delete from.... the table grows to 6GB
The repopulation of the table uses mutiple insert statments commiting after each one.
is this a bug or is there an action i should perform onece I have deleted the data?
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bi

Is this an Index Organized table ? (select IOT_TYPE from user_tables where table_name = 'DJ_20255_OUTPUT' ;)
Are you saying that you use this sequence :
DELETE .... in one single call to delete all the rows
INSERT ... in multiple calls with COMMIT after each row

Hi
We get "Error reading table t77www_mnt" on My First Day

OAI_AGENT_ERROR table growing rapidly

Any help is much appreciated!
Thank you

HI
"oracle.oai.agent.server.transform.database.DBTransformationException: PLSQLTransformation.transform: Transformation failed" in the log file means this error occured at agent level /application level.So,using metadata interconnect is not able to convert input data in to application view.
Error is transformation failed.So reason can be
--> any unhandled exceptions
--> mismatch in data type of fields/parameters used.
--> mis match in number of field/elements in input data.
Transformation failed indicates interconnect not able to transform input data in to sepcified format in Application view or common view.
As you mentioned,this is happening only with few records.
--> check if failed records are to test negative cases.
--> check if failed records have all values expected as mandatory for transformation.
--> check if failed records have the data with expected datatypes(For eg field a is defined as number and field a in record have value 'abc' instea dof 123).
Hope this information helps you.

by using below stored procedure i can count the total number of pairs under particular node in 2:1,1:1 ratio means first pair is completed when two node added to the left side of given parent node and one node added
right side of given parent node after that all pairs are completed when one node added left side and one node added right side of parent node (1:1 ratio)
example if i execute my stored procedure as follows it would return following.
EXEC count_pairs 'Ramesh123'
3
so there is 3 pairs as shown in my figure.
when we execute my stored procedure for ParentID 'sonu' it would return following.
EXEC count_pairs 'sonu'
2
so there is 2 pairs as shown in my figure.
My problem is to find the query which can return the total number of pair under particular node any given parent node. day to
day maximum 5 pairs in a day please any one can suggest us

I don't think this is homework, I am not sure how helpful it was by Kalman to merge the two threads. It appears that two different persons posted the questions. It could be though, that it is the same problem and Jitendra has taken over Chandra's
task.
However, I was not able to understand the problem nor the figure. And nor the definition of pairs in this context. My assumption is that what Jitendra posted is an abstraction of the actual problem in order to not reveal intellecutal property. Possibly this
makes the problem more difficult to understand for us outsiders.
I've come so far that I worked out a table definition and INSERT statements with sample data, as well as a call to the procedure which returns 3 and this appears to map to the figure, but I don't know what it means. Since I don't know what this
is about, I have not made any attepmts to understand the code, but I would appreciate clarification about the underlying business rules as well as the expected results for various test cases.

Day-to-Day Activities of a guy in a Realization Phase???

Hello BW Experts,
What are all the main Day-to-Day activities of a (Junior/Seniorl level ) guy in BW Realization Phase?? Plz let me know the following Qs:
1. Whats the General procedure usually BW Implementing org. follow to Install the required Business Content(ODS/Cubes etc)??
--> Plzz throw some light on Top-Down & Bottom-Up approaches and when and where we use them.
2. Is creating /Modelling the required objects is the only job done by the junior level consultants seeing the Tech specs given to them?? (or do they also participate in any of the above i.e., Top-Down & Bottom-Up in finding the exact content of the requirement)
Wholly, My actual doubt is do they participate in
--handling Performance related issues,
--deciding the nearest possible business content to be installed,
--adding new fields to the append structures in datasource enhancement
or They (junior to senior level cadre) just involve in installing business content and developing reports and modeling objects ??
Plzz clarify my Ambiguity...
Thanks in advance.. and I assure points.
Sapster.

Hi,
In realization phase a bw consultant will do the following set of things:
1. creating different objects like Infoobjects, Infocubes, Ods objects, infosets etc..
2. Maintaining and activating these objects.
3 Rectifying the errors.
4 enhancements.
5. gap analysis
6. generating reports
7. Looking in to issues related to transportation. etc.,
Hope it helps u a lot
Thanks & Regds,

Is there a report to display tha balances of a G/L account day by day?

Hi All,
I'm looking for a report to to display tha balances of a G/L account day by day (the cumulative balances too)
T.code FS10N shows me the balances of a G/L account period by period, but not day by day.
Could anyone help me?
Thanks

Hi Jeyakanthan ,
I've checked it, but the balances aren't available in that report.

What organizer app has a really good WEEK VIEW like my Palm Pilot - it's a grid with days across the top. Below each day- the day is divided into hourly grids. When events are schdeuled across week - you get a mosaic of time blocks. Analogue - great

What organizer app has a really good WEEK VIEW like my Palm Pilot - it's a grid with days across the top. Below each day- the day
is divided into hourly grids. When events are schdeuled across week - you get a mosaic of time blocks. Analogue view is great way
to comprehend the time obligations as a molar pattern.
thx,
Fritz

I use Week Cal on the iPod. I think it was only $1.99. It is a lot better and does a lot more than the one that came with the Palm Pilot.
As you know, unlike the Palm Pilot, the iPod does not come with a desktop application that you can sync your iPod calendar to. Since I don't use Outlook, I have to use a Cloud based calendar to sync with my PC. I use Hotmail's calendar for that. (If your computer is a MAC, you can use iCal)
