Cognos Clear Core Dump File - Eartheration/IBM-Cognos-Wiki GitHub Wiki

Core dump files are created when there is a serious problem, such as an unhandled exception or when an IBM® Cognos® process terminates abnormally. Since core dump files are big and a new one is created each time the problem recurs, you may want to disable them. You can enable core dump files again if you encounter problems that require it.

If such a problem occurs, you receive the following error message: Report Server not responding. See the Troubleshooting section in the Administration and Security Guide immediately.

You may also want to delete any existing core dump files from the \bin directory of the IBM Cognos server installation, if they are not required for troubleshooting purposes. In a Microsoft® Windows® environment, core dump files have a .dmp extension and the file name processID.dmp, such as BIBusTKServerMain_seh_3524_3208.dmp. In a UNIX® environment, the files are named core. In a Linux® environment, the files are named core.processID.

In some IBM Cognos hotsite builds, core file creation is automatically enabled. The configuration file that controls this is different for IBM Cognos 8.1 MR1 and later versions of the product. During an upgrade, configuration settings are not overwritten.

1. On the server where IBM Cognos BI is installed, open the rsvpproperties.xml file from the c10_location\configuration directory.

2. Change the Win32StructuredExceptionHandling property to 0 (zero) so that it reads

Win32StructuredExceptionHandling 0

3. Save the file.

1. On the server where IBM Cognos BI is installed, open the cclWin32SEHConfig.xml file from the c10_location\configuration directory.

2. In the configuration element, change the value of the environment variable setting to 0 (zero) so that it reads

<env_var name="CCL_HWE_ABORT" value="0"/>

3. Save the file.
