Hello experts!
I have a mysterious problem with my BO environment: sometimes (usually 1 time per day) BI launch Pad stop to work. By the browser is possible to load the login page, but after to put the credentials and click on logon, the page enter a loading loop, keeping a blank page. To solve this problem is necessary to restart the SIA service.
Some points about this problem:
1- This occurs only with BI Launch Pad, so, is possible to logon on CMC and OpenDocument for example.
2- After to problem occurs, verifying on CMC, there is a active session created for that logon on BI Launch Pad, so, the logon occurs but the page don't load.
3- There's no error log on Event Viewer of Windows, and there's no exact time to occurs, sometimes occurs at morning, sometimes occurs at afternoon, sometimes occurs more than 1 time by period, some days don't occurs. I did a study with the log on Event Viewer and I didn't found a relation between others events and the BI Launch Pad fail.
4- This problem occurs in my both environments, development and production.
5- To restart Tomcat does not solve the problem. The mysterious is: why BI Launchpad stop to work and CMC continue working?
My environment is:
- SAP BO 4.1 SP5
- Tomcat 7
- Repository and Audit database Oracle 11G
- Windows Server 2008
- Those servers are virtualized (VMware)
- I work with SAP authentication and my reports work over BW (This problem occurs with Enterprise and SAP authentication)
- My BI Launch pad is customized like this tutorial Branding and Theming of BI launch padand official documentation SAP BusinessObjects BI Customization Guide.
