Disable the Creation of Core Dump Files
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 IBM Cognos Business Intelligence Troubleshooting 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.
