We often have issues with collecting performance data or accessing the DWH server or reporting. Error messages are similar to these: (HTTP Status 404 - /dwh/ - The requested resource (/dwh/) is not available. (JBoss Web/3.0.0-CR2))
We found, that the directory 😧 \ SANscreen \ SANscreen \ cognos \ c10_64 \ bin is completely full of dumps with files "BlBusTKServerMain_seh_nnnn_nnnn" between 196 MB up to 600 MB and there is no more space left on device. (Why these dumps arise, unfortunately could not be determined yet.)
After deleting the dumps, everthings works fine again, normally.
Now we can't get a Backup of the DWH: "Failed to backup DWH: Failed to connect to reporting server, server might be down. Confirm reporting server availability and try again." Also a connection to the reporting is no longer possible.
DWH and Insight Server are working. Services
- SANscreen Server
- IBM Cognos Content Database
Service "IBM Cognos" has no status. Starting the service manuall we got : "The IBM Cognos service on Local Computer started and stopped. SOme services stop automatically if they are not in use by other services or programs".
The installation of external Java applications, upgrades, or server patches on OCI/DWH server can cause the deletion of the Javasoft registry keys resulting in issues such as these.
Perform the following steps:
1. Run regedit.exe and check if the keys exist in HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Prefs\com\netapp\sanscreen\reporting 2. If the following entries do not exist or are not specified, create them: dispatcher_url 'http:\INSERT_HOST_NAME_HERE/p2pd/servlet/dispatch" portal_url "http:\INSERT_HOST_NAME_HERE/reporting'
Hope this helps.

Go to the ..\data directory of the IBM Cognos installation directory.
Check for a file, with a similar file name like C260M3A64P_cognos10SYSTEM_G21
Make a backup of this file and remove it from the ..\data directory.
Repeat step 3 and 4 for all dispatchers configured with IBM Cognos Query Service.
Start the Cognos environment.
Unfortunately without success.
I've already rebootet the system; nothing.
The "IBM Cognos"-Service becomes always the status "Stopped". ("The IBM Cognos service on Local Computer started and stopped. Some services stop automatically if they are not in use by other services or programs.")
The problem is covered in Case # 2006578161. At the moment everything works fine, except for the constantly created dumps, which only make problems when the drive would be full. So I just delete them every few days.
I have the NetApp Support already suggested to update OCI to the latest version. I'm still waiting for the answer.
