Essbase database has exploded!

Hi,
We have a Essbase database which used to be around 1.9 GBs till a few days back. Recently the scenario dimension was made dense to improve performance. This should have reduced the total number of blocks and increased the blocksize. In our case the total number of blocks have increased many times - hence the size has increase by 2.5 times. There has been an increase to our block size (which is something that is understandable).
Also Hour glass was changed to hour glass on stick model. I am not sure if this would have caused this.
There have been no changes to the outline.
We are still investigating but any input would really help get to the bottom of this.
Thanks,
Amol

Something doesn't make sense here.
Recently the scenario dimension was made dense to improve performance. This should have reduced the total number of blocks and increased the blocksize. In our case the total number of blocks have increased many times - hence the size has increase by 2.5 times. There has been an increase to our block size (which is something that is understandable).Think about this (yes, I know, this is why you posted the question) -- you have taken a sparse dimension and made it dense -- if that is the only action it must reduce the number of blocks. How can you have gotten both a larger block size and an increased number of blocks? The only answer I can come up with is block change + additional data. Compression has nothing to do with the number of blocks or the size (okay, the logical, not the physically stored). I'll also throw in maybe the number of members in still sparse dimensions also grew and were loaded.
However, if you made the block bigger (and I would question Scenario being dense, but I don't have access to your database) through a dense Scenario, and more data (more months, years, days, products, whatever) then sure, your IND and PAG files could get so big that at least the PAG file breaks the 2 gig limit and spools to new files. If your data storage has been so defined, it could be on separate volumes.
The above change is why we have test, QA, and production environments, right? :)
Of course, I've had clients tell me, with only a slight trace of irony, "There's no test like production," so maybe you're in the same boat.

Error While Creating Essbase Database From Hyperion Planning

Hi,
While creating the Essbase Database From the 'Manage Database' in Hyperion Planning, I am getting the following error:

It gets stuck at Adding Dimensions.
I have tried reconfiguring Planning, but no luck.

Have you tried restarting the services and giving it a try?
Which version of Essbase/Planning are you on?
If your Essbase server name has more than 30 characters, please use NODENAME with short server name.

Accessing Essbase database from BI Admin tool

Hi,
I want to create a new RPD using Essbase database.
I want to know how to configure Essbase data source so that I can use it for my rpd file.
I have BI server installed on server machine and BI admin tool on my laptop
I am using version 11.1.1.5.0
From manual what I understood that on BI server machine, Essbase client libraries must be installed and the same client libraries should also be installed on machine where BI admin tool is installed.
I tried to ask my collegues, but got different openions. Some of them said essbase client libraries are not required on machine where BI admin tool is installed.
Please tell me correct way and step to configure Essbase as datasource for my RPD, wether I need to create a DSN on my laptop poiting to Essbase datasouce , etc.
Thanks and Regards
Santosh

Hi Bala..
Thanks for your help
Can you tell me where is the bi-init.cmd file located?
I installed BI admin tool on my laptop, but could not find this file in any folder..
According to manual, I understand that to access Essbase data source, I need to install Essbase client libraries on BI server and on laptop where where BI admin tool is installed and
creeate two variables and set them in bi-init.cmd file.
Nw I want to know whether I need to create those two variabvles on BI server machine and update bi-init.cmd file on BI server or I need to create those two variables on my laptop where I have installed BI admin tool? As I mentioned above I dont see any bi-init.cmd file in BI admin installation which I did on my laptop.
Either my installation has not happened, or this file is created on BI server and not on my laptop ?
Please help me to understand the problem. I need to create Essbase datasousrce connectibvity and create a RPD based on this data source.
Waiting for your reply.
Thanks
Santosh

Unable to open Essbase Database

Hi,
Following Essbase error is coming when data is fetching from Essbase database from a report: -
Failed to open database 'Database1' on server 'URL'
Error reported by Essbase.
Additional information:
Syntax error loading filters - operation canceled
Kindly tell what could be the reasons behind it??
Regards,

Hi,
Followiong could be the reasons of your problem: -
1- Try to restart application and then try to start database.
2- If point 1 not work then may be application process 'ESSSVR' for that application get hangh. So stop all app/db and check if any Esssvr is running from Task Manager then kill it.
3- Restart Essbase Server and try to restart db again.
4- If problem still persists then may be your db got corrupted and please restore it from backup.
5- Also from your posted error, it is looking that Essbase internal application $DM_APP$ is either missing or corrupted so please make it in following ways:-
5.1. Shut down Essbase
5.2. Rename essbase.sec to essbasebackup.sec
5.3. Rename $DM_APP$ directory, e.g., Backup_$DM_APP$ if it exists but if it doesn't do not worry about it.
5.4. Restart Essbase. At this point, a new essbase.sec is created,along with a new $DM_APP$ directory and files associated withit.
5.5. From EAS, make sure Data Mining part is working
5.6. Shutdown Essbase
5.7. Rename essbase.sec to essbasenew.sec
5.8. Rename essbasebackup.sec to essbase.sec
5.9. Start Essbase
5.10. Check to make sure Data Mining part is working
5.11. Try renaming application or load db
5.12. Once all is working, remove essbasenew.sec.
Hope it will help pyou.

Your positive reply will be appreciated...
Thank you very much in advance...

As for adding members to the outline, you can either do it manually (not too painful for a Time Periods dimension), or if you have the members you need in a file, or available via SQL, then load 'em up using a Load Rule. Using the Parent/Child relationship is one of the preferred methods, but that means your source data needs to be in a parent / child relationship.
There are other ways in the load rule, Generation, Level, etc, but if your source data isn't very good these methods of building the dimension can be a little harder to control.
Here's a link to the DBAG for dataload rules.

New free Oracle XE database has a PHP manual

I wanted to point out that the newly announced free Oracle XE Beta version of the
Oracle database has a PHP manual. See
http://www.oracle.com/technology/products/database/xe/index.html
The direct link to the manual is:
http://www.oracle.com/pls/xe102/to_toc?pathname=dev.102%2Fb25317%2Ftoc.htm&remark=portal+%28Getting+Started%29
The manual is a step by step introduction to building a simple application (it constructs
pretty much the same application the Java and .Net manuals for XE do), so don't
expect any deep revelations about PHP
Post any PHP on XE feedback here or on the XE forum:

FWIW, I just came across this post from Harry Fuecks about XE and PHP:

Tabular form Update Error,"Current version of data in database has changed

I'm getting an error when updating a Apex Tabular form. It's complaining that the row id's are out-of-sync. The error reads,' Current version of data in database has changed since user initiated update process. current row version identifier = "56DW5A8A7EBA3B42073AE6E71480A784" application row version identifier = "99B52A15F10E34647E9E18B6B7AE8C30" .
Has anyone received this error? Any solutions? Note that the primary is being populated by a trigger. I have another tabular form for a different application that updates without issue, this however, uses a sequence to update the primary key.
Thanks,
James

Make sure that the form is defined such that it "knows" that the PK is being set by a trigger. Do not try to set it in the form if the trigger is doing it. Pretty much if a trigger attempt to modify any column that also was editable (including hidden columns) in the form, the two will conflict.
The other issue could be that do you have any items on the rows that are disabled? Disabled items are not sent to session state so Apex won't be able to properly compute the checksum and it'll find a discrepancy.

APEX Error: Current version of data in database has changed since user init

Hi:
APEX 4.1
I have a page with 2 regions. The first region is built with custom SQL using the APEX APIs. I have a process the can successfully update records.
I built the second region with the tabular form wizard. This created the multi row update process.
I created a region button and the two process respond to that button: process for first region, then process for the second region.
When I add data to the second region and click the region button, I get the following error:
Current version of data in database has changed since user initiated update process. current row version identifier = "A884FA378C851786DDFE3A33709CB23C" application row version identifier = "9ED06A0F09F80F054AB781CA24CC4CBF"
I know it has something to do with these two types of regions being on the same page, because when I create a page of just the table form, the data is updated.
Can anyone suggest what I might be doing wrong?
Thanks.

Hello
If you try update the same data from 2 places you will got this message because:
Apex forms have locking mechanism.
1. During fetch data to form apex calculate checksum from every items on the forms.
2. Before update process apex again fetch data from database (in background) and calculate checksum again if checksum from point 1 is the same like this checksum APEX realy update data with new item values. If no, You will got your error (apex secure You, You realy don't know what you update).
According this if you change data which you use in the form between 1 and 2 point you will got this "error". You can check it for example if you change data from SQL/Plus or from other form.
Probably you forget about this locking mechanism during designe your process from APEX API <- successfully update records (maybe successful but you don't know what you updated) : )
If I helped You please check correct or helpful :)

MRU Error : Current version of data in database has changed since user init

When i use HTMLDB Wizard to create Master Detail Form
(You can see step by step what i doing by see this url :

The is error in MRU :

If there something missing.., just say ..
Thanks for the help.

Oh i see ..,i never think if that is the source of the MRU
error.
Ok ..,
Now ..., i have new question .., how can i change so the the primay key in detail table (enrollment table), i have one primary key with two columns .., if you don't understand what i mean ..,
check this alter table statement :
ALTER TABLE ENROLLMENT
ADD CONSTRAINT ENR_PK PRIMARY KEY
(STUDENT_ID
,SECTION_ID) ;
Now the question is .., when i using wizard to create master detail form .., html db automatically make student_id and section_id as the primary at "application level (html db)" .., how can i change this behaviour ..,
i want the html db not treat this two column as primary key ?
Do i have to create master detail form manually to accomplish this ?
Thanks before .., sorry if my english is not too good.

How can I solve this problem?
Also,I am getting the above error once I change the query for another tabular form.The client wanted some more fields to be displayed on the page.
How can I solve this problem too?

Generating Essbase database for Hyperion PerformanceScorecard, HPS v1.1.1.3

Hi,
We're working with HPS v11.1.1.3. The Framework is developed without any issues.
A data source connection could be established for Essbase & synchronized periodically.
However, while we tried to generate the Essbase database from- Administration (menu) -> Star Schema Generation, we hit a roadblock. It failed with the below error message:
*"Exception generating Essbase cube (via Integration Services): Star Schema generation failed"*
Did any of you get to see the above error?
To troubleshoot, we did the below-
(i) The generated xml files (for OLAP Model & Metaoutline) are imported to an EIS catalog. No problem here.
(ii) When we manually tried to load the metadata from EIS, it didn't let us proceed due to an error: Two of the tables used in OLAP Model don't physically exist.* To our surprise, they do exist.
(iii) We manually modified the OLAP Model by deleting the troublesome tables & drag-n-dropped them again. Ofcourse, in this process, we had to tamper metaoutline too
(iv) Now, with the modified EIS artifacts, we were able to load the metadata _(,with very few rejects)._
Before raising an SR with Oracle, I thought of checking with you experts incase one of you happened to have faced this & got it resolved. Please advise.
Sorry for being verbose!
Thanks!

Hello friends!
I have the very same error. I've opened a a SR in the oracle support but till now no solution!

String retrieved from Berkeley database has one more abnormal char

Hi,
The value I retrieved from my Berkeley database has one additional char, compared with the value I saved to the database.
For example, I put this pair into the database:
key: JRE
value: update
The value I retrieved using the key "JRE" was printed as "update", however, when I checked the length of the value, it is 7.
value[0]="u"
value[1]="p"
value[2]="d"
value[3]="a"
value[4]="t"
value[5]="e"
value[6]=" "
My retrieve function is:
//Retrieve String-String pair
public String RetrieveStringValue (String key) {
          String value = null;
          DatabaseEntry keyEntry = new DatabaseEntry();
DatabaseEntry dataEntry = new DatabaseEntry();
StringBinding.stringToEntry(key, keyEntry);
if (exampleDb.get(null, keyEntry, dataEntry, LockMode.DEFAULT) ==
OperationStatus.SUCCESS) {
value = new String(dataEntry.getData());
return value;
Does anyone have an idea?
Thanks

Hi,
Without seeing the complete code for writing and reading, it's impossible to know what's happening.
But one possibility is that you're using "new String" and you should probably be using StringBinding.entryToString.
