Ω Ω Ω Ω Ω ……. Good day everybody and welcome back……… Ω Ω Ω Ω Ω
As promised that I will post a couple of interesting stuff down the line for next couple of days …Here it begins .. :)
In my recent execution of a OBIEE 11g development project several unforeseen events have been experienced which is either a product defect or an enhancement issue encompassing couple of 11g new features or the existing feature having enhancement issue. Most of them are from UI perspective and some of them from Repository perspective. I like to jot down those points that could be useful for future reference. All below issues noted are as per my observations that might not necessarily true as those depends on the situation and the environment where I have faced the problem.
I am quite sure there will be tons of problems on the way while upgrading the 10g to 11g especially from the customization perspective and architecture perspective. I will update it as soon as I will be facing such concern down the line …. !
♦ Issue #1
While added a filter on Top 20 TRx measure value and then edit the same measure value from the report filter as below:
IFNULL(NNI Weekly.Curr Week TRx,0) is in top 20
Changed the expression and after removing IFNULL I can see “Is in Top” option vanishes. So you can’t choose numbers anymore that in which ranges it belongs to.
♦ Issue #2
While restarting BI Components (Presentation Server, BI Server and Scheduler) from OFMW enterprise manager console it suddenly throws errors at the end of restart process. However the log and other information are not meaningful but the entire things were up and running behind the scene. Not really sure about what is the meaning of the error.
But it seems there is a communication delay between BI Server components and the Windows Process manager OPMN and once that delay is over all the components work perfectly in sync. Until OPMN also up and sync with BI components you will get error “Error 500–Internal Server Error” in bieehome page URL.
♦ Issue #3
Alternate inner coloring in pivot table row format actually overrides the measure column format label color specifications format once that measure bring from column section to row section.
♦ Issue #4
While you edit the page all the hidden page also visible and can also be edited like changing the entire page layout components. I think this is intentional and not an issue rather it gives the flexibility of altering the components even if those are hidden in actual dashboard page.
♦ Issue #5
The dashboard page level slider prompt control took unnecessary vertical whitespace from the end of the prompts till the Apply/Reset button causing the much more vertical section space for prompt. So even if, inside the control it is specified that the Button will be placed to the side of the prompt it doesn’t behave like that. So I think this is a bug to fix.
♦ Issue #6
Editing the compound layout from the dashboard page layout where it is specified to expose the view for say “Compound layout 3” rather default compound layout it should open the Layout 3 in the edit page. But it is not the case currently and always opens the default compound layout. I know, even the components specific editing feature was not there in 10g as well. But as a developer we could expect much more on that which helps our life cool.
♦ Issue #7
I encountered intermittently “Bad XML instance” while adding multiple prompt values in report filters and it doesn’t allow saving that report. Don’t know the reason about it but once I log off and log back in again everything is fine and I can even add those prompt criteria’s without issue.
♦ Issue #8
OFMW Enterprise Manager console weblogic user is not case-sensitive and due to that reason when you enter using the user ‘WEBLOGIC’ say (all in caps though actual user is ‘weblogic’) you can logged in see all the pages and options and it allow to lock and edit the configuration button press. But once you click that you will see all the fields are still not editable and there will be no button called ‘ Release Configuration’ or ‘Activate Changes’ .So either it should allow all the functionalities or not allow to log into EM console at all .
♦ Issue #9
Changing the prompt text/label color and style will change the default section value of the prompt format as well. For e.g. if we change the prompt text color it will change the default value set in the prompt as well.
♦ Issue #10
Pivot table exclude is possible but not include in the non-designer mode. For e.g. once your report is ready and placed into the dashboard, right-click on some column and click to exclude some column from the pivot table display. You can do it. But you can’t get those excluded column back from the same section. Instead of that you have to click on reset page display or ‘Clear My Customization’ to get those column back into the pivot reports.
♦ Issue #11
Add to briefing book option is not displayed even if it is enabled in the dashboard layout against the displayed components. The problem happens when, instead of displaying the default compound layout or other compound layouts you are displaying the view like ‘View Selector’ etc.
♦ Issue #12
OBIEE 11g User Interface (UI) Performance Is Extremely Slow with Internet Explorer 8 (- IE version 8 – ) .Follow my previous post to get the details. Due to the browser problem several issues like below you can find while developing your reports.
♦ Changing the colors of the measure attribute behaves erratically and it doesn’t reflect on time in inline view and once the reports have been saved it is back on color.
♦ Sometime compound layout views displayed only without any control activated and hence browser needs to be closed after log-off and only solution to log back in.
♦ Issue can be appeared in Style Formatting for Graph. The spikes and the pointers (triangle, round) doesn’t display correctly.
♦ Issue #13
Saving the online 11g BI repository after modification of several components inside it ,the consistency checker failed throwing a weird kind of error message below:
[nQSError: 37005] Transaction update failed.
That is documented under Bug 9884975 (11G ADMIN TOOL RECEIVES NQSERROR: 37005 WHEN SAVING ONLINE RPD CHANGES 18.104.22.168.0 – version Microsoft Windows (32-bit) )
And the resolution Patch 12909840 – GETTING ERROR:  INTERNAL ASSERTION: CONDITION M_LOCK.ISACQUIRED() available on request from Oracle.
♦ Issue #14
11g RPD has thrown the error message while query on object from Physical layer and double-click that object to get the details.BI admin tool has thrown error “Object is orphaned and should be deleted”. The cause is unknown however I search the object and find it using pair of eyes and double clicking it is fine ! So weird no?
♦ Issue #15
I have encountered a strange error appeared while playing with OBIEE 11g repository. The error message as below:
“nQSError: 43113” – Message returned from OBIS
“nQSError: 46036” – Internal Assertion: Condition COLOCK_ISSET (value) , file server \objectmodel\Src\SORpObject.cpp , line 3
I have not found any such error logged in Oracle Support and not sure about the reason. However the problem resolved after closing the Admin tool without saving the changes and re-opening it!
♦ Issue #16
Graph slider (11g new feature) causes some unpredictable issues if you like to play with it more and more!(changing the sort order , randomly moved the column across several places in layout view , changing the measure data/column format). I had faced some unpredictable issues and in place of Graph slider it displayed like an error with message and my slider control vanishes. However I got it back after 2-3 days after several restart. Might be a kind of rendering issue in IE8 is responsible for that. Now I switched to Firefox hence not having any problem until now.
♦ Issue #17
While adding the Groups (11g new features) inside catalog level, the values doesn’t change automatically until and unless Cancel button has been pressed. Once u click on Cancel button hold your mouse button and come to other section and release the button pressed you can see the value changed.
Ω Ω Ω Ω Ω ………..Until next.. Good Bye! Stay tuned…………Ω Ω Ω Ω Ω
