Delivers unable to refresh Report through Cache Seed

Hi
I am using delivers to refresh the Oracle BI cache.
I have created a Report & run the report, saved.
Cache was enabled at this moment. Now the report was cahed.
I have created a iBot on this report and sheduled.
After this... i updated one of the values of column in database.
Now i try to schedule the report as i thought that the cache will be refreshed.. for this iam checking the check box "Oracle BI Server Cache" Cache Seeding option present in Destination tab of Delivers. When i fired my iBot at this moment i am unable to get the updated records which means the cache is not refreshing...
Can you explain procedure how to refresh the Oracle BI Server Cache.
What is the Cache seeding..?
Thank You..
G. Kishore

Seeding cache means you are employing a mechanism (manual or automatic) to pre-populate the cache entries so your first user(s) don't have to wait for data to be displayed on the screen.
To seed a cache one presumes the cache is empty -- at least for the entries in question. You might have some data that changes yearly ... so you never remove those cache records unless the year is done. You might have daily data that you need purged and re-seeded every morning. You might have such good database query/network/BI Server performance that your users will actually perform the seeding for you (but then it can be argued why have the cache at all); but usually the DB/network/BI Server performance is such that we want to cache data, purging and re-seeding as needed.
Also keep in mind: caching is the LAST step in a comprehensive OBIEE performance strategy.

Unable to refresh reports in InfoView or CMC

Recently we went from CR10/ePortfolio to CR2008/Infoview. Now when I publish a report to BOEnterprise and try to refresh that report in InfoView or the CMC it fails with the following message: Error: The database logon information for this report is either incomplete or incorrect.
The report runs fine from the designer, whether it is run from the network or the Report Application Server (Enterprise). When I publish the report I select the "Use original database logon information from the report" option in the Database Configuration utility. Although, I have tried all of the settings to no avail. The DSN resides on the server as a System DSN and tests successfully.
Any ideas would be greatly appreciated.

Unable to refresh report field definitions in CR XI

My report is using Java Bean class as datasource and the Java Bean class calls a report-specific Java program to return a result set.
In the Field Explorer, I can see the fields of the result set under Database Fields tree.
I modified the Java program to add a new field in the result set; went to Crystal Report Designer, clicked Database menu and selected Verify Database. The program ran without error but I did not see the new field in the Field Explorer.
Can anyone tell me how to refresh the report schema to show the field I added?
The temporary solution is to create a new rpt file, use the Java Bean class to call the modified program to populate the new field along with old ones. However, I am forced to redraw the report layout which is a real pain.
Can somebody help?

After modifying the Java program, have you recompiled your java file?
After recompiling you will need to restart the designer to see reflected changes.
Thanks,
Tej

Cache seeding

Hello All.
I have several dynamic variables used in a analysises and graphs and then in they used in a dashboard.
I have a schedule task running to refresh the data (cache seeds).
I have recently learned that if I utilize dynamic variable then the cache is purged by the BI server.
And the user offers a solution to "set up a cache seeding .bat file that runs after the dynamic variable has been updated. "
We are using Oracle BI 11.1.1.5.0
Can anyone clarify how to do this?
Perhaps this issue was resolved already by Oracle??
Thank you,
Sonya

Should we Use cache seeding iBots to pre-cache the reports ?

Hi Everyone,
We have requirement from client to improve the performance of some reports.We have a very old RPD and it is really huge so we don't want to do much on database side for performance tuning.
Will it be a good idea to use cache seeding iBots to pre-cache the reports ?
Most of the reports which are having performance issue are having some 5-6 columns and one key column is having some 30+ choices in column selector.So for each column selector view we will have to create a ibot which will again be a huge task.Can you pls guide how to approach this?
Thanks in advance !

hi Aarti,
Will it be a good idea to use cache seeding iBots to pre-cache the reports ?http://www.artofbi.com/index.php/2010/03/obiee-ibots-obi-caching-strategy-with-seeding-cache/
30+choices in column selector will definitely have performance issues..bcz each and every time the report is going to refresh .have u enabled the cache some what better .Whats the issue of using existing report by enabling the cache seeding in ibots?

Hi David,
Previously I am seeding the cache by nqcmd utility, its working in some pages and not working in some pages due to the repository variables (current quarter and current week variables are used in the prompts) used in some Dashboard prompts.
So we are not meeting Business SLA due to this issue.
Now I am trying seed the cache through Ibots where ever we have the cache seeding problem. When I run an Ibot, I don't see any Queries cached in Manage--->Cache in Admin tool.
We already had a Ibot setup which is running after every ETL load in the production and sending reports(emails) to the users ( In this case I see that the queries are cached).
In the same way I am trying to setup the Ibots not selecting and any recipient and selecting destination as OracleBI Server Cache.
Am I missing anything here ....
Please help me guys... this is a production issue....
Thanks in Advance...

USER UNABLE TO REFRESH DISCOVERER REPORT IN DISCOVERER DESKTOP 10g

Dear All,
HELP!!!
A new user is unable to refresh discoverer Reports in Desktop. All priviledges have been granted to username in Disco Admin and Usre is able to log into oracle Apps.
On the PC the user logged into someone else can log into Discoverer Desktop and run/refresh discoverer reports without any issues. Hence Ithink neither the PC nor the Discoverer installation is the problem.
Can anyone help? What setup/profile needs to be completed in order for the user to be able to run Disco reports.
Pls note that the following has been completed:
1. Business Areas Assigned to user and his responsibilities.
2. Desktop/Plus Privileges assigned.
3. Allow administration - DISABLED - NOT TICKED
Many thx
DI

Does this person just need to run reports? Or does this person also need to create reports? If the person just needs to run reports, try using Viewer for that person, rather than Desktop. This may be something that you need to log a service request with Oracle to get resolved. Pretty strange that can bring items into a new worksheet, but it won't run. Maybe there is an Oracle applications security issue (since logging in as another person does work)? You may be beating your brains out trying to find a Discoverer problem when it might be an application security problem. Though this is a wild guess on my part.

Unable to refresh a report in P21 Activant

We recently upgraded our Activant P21 (Prophet 21) software which includes Crystal Reports. Standard P21 canned reports in their software can be viewed, exported and printed. The P21 software includes a feature to create and link custom reports. We create the custom reports with Crystal Reports 2008 and set up the external report links. We can open, view, print and export the custom reports but when we refresh the report with or without an input parameters, we are prompted for a "Database Login" password. When we enter our password, an error message titled "Crystal Report Windows Forms Viewer" states "Logon Failed. Please try again". We have contacted Activant about this issue and they do not find any errors in the set up. They have told us there is probably an issue with Crystal Reports and asked us to contact your company. We have also contacted a friendly competitor who uses the same Activant P21 software and create custom reports with Crystal Reports 2008 which include user input parameters. Their custom reports work without a glitch. What would prevent us from refreshing a custom Crystal report?

Hi Don,
Activant P21 is insisting our issue is a Crystal problem. We are unable to refresh the reports inside their software. We have tried every user id and password we know and it still will not refresh our CR report.
When we use CR2008 to refresh a report, a window opens titled "OLE DB (ADO)" and asks to choose a data source "ODBC Data Source....Choose a data source from the list" We select our ODBC DSN: P21 Live and click next. Another window opens titled "OLD DB (ADO) asking for a password "Connection Information...Provide necessary information to log on to the chosen data source." At this point it does not matter what "User ID" or "Password" we use, the report will refresh. We have used the Adminstrator with a password, we used my user name and password and we used the administrator without a password and in all three instances, the report refreshed with the correct data.
I don't see how this is a Crystal problem unless there is something I am missing. Any help you can provide will be deeply appreciated.

Unable to run a report through Portal.

Hi All,
I am not able to run a particular BEX report through portal.
I get a white screen and no pop-up for selections and later nothing happens.
I have checked my Roles but no changes has been made.
My other colleagues are able to run the report.
Please let me know what could be the possible reason/solution for such an issue.

are different roles assigned?
i.e., for you and for your colleagues. Please try login with your id in their PCs and vice versa.
let check the compatibility. if you are failed to execute in that PCs also, then it should be authorization issue. Ask your basis folks to add that particular info area and info cubes to your role.
Hope this would give you clear pic.

Automatic Storing of Report Through Delivers in PDF Format to Local Disk

We need ihelp on our problem below.
Goal : We want to automatically download the IBOT reports in to a PDF file on our local hard drive for archiving purposes. We are able to get this working and the code is working fine with IBOTS calling Java Script in Windows environment and IBOTS calling Java Classes for AIX (our obiee is installed on AIX).
Problem : Java script code is able to return the name of the report which is chosen as the content for the IBOT -> under Delivery content Tab select content tab(containing the name of the report). Thus my downloaded PDF file is containing the report name which is good and what we need.The Java classes have been combined as a JAR File with 3 other dependency JAR Files which are needed to talk to the Scheduler Classes which are as follows.
C:\OracleBI\web\javahost\lib\scheduler\schedulerrpccalls.jar
C:\OracleBI\oc4j_bi\j2ee\home\applications\xmlpserver\xmlpserver\WEB-INF\lib\xdocore.jar
C:\OracleBI\oc4j_bi\j2ee\home\applications\xmlpserver\xmlpserver\WEB-INF\lib\versioninfo.jar
However when we now invoke the ibot with java classes on AIX box,we are not able to get the name of the report in the download file. We are not able to find the right JAVA supported method for OBIEE delivers to get the report name. In short what we want is the equivalent of this Java script code below in Java classes for OBIEE.
Java script which returns the name of the report is done by this one line code.
var foldername = GetConfigurationValue("Log Dir", "iBots") + "\\" + UserID
we need the equivalent of this "GetConfigurationvalue" in OBIEE scheduler Java classes to get the name of the ibot.This is a mandatory requirement from the business users to have the name of the downloaded report on the AIX Box using IBOTS and Java classes.
Thanks

Portal Runtime Error while accessing BW reports through portal

Hi,
We are facing portal runtime error(An exception occurred while processing your request. Please send the exception id to your portal administrator) while accessing BI reports through portal frequently.
