What Do I Do If My Drivers Produce Intermittent Core Dumps?

No product should produce a core dump. Core dumps warrant the creation of a bug report. (Update existing bug reports, as appropriate.) Product Support Staff should attach the core file to the report. Moreover, staff must gather the following information from users:

  1. Does the database and operating system contain all current patches?
  2. Are the patches associated with stability problems?
  3. Do Unix kernel tuning parameters match parameters specified by database and o/s documentation?
  4. Does the machine have adequate memory and processor resources?
  5. Was the database agent re-linked against the database?
  6. Is PortHigh set in the [Protocol TCP] section of the Multi-Tier Session Rules Book? This is the oplrqb.ini file that resides in the /bin sub-directory of the server components installation.
  7. What happens when users comparison test the following ReUse values:
    • ifsame process, upto 5
    • ifsame application, upto 5
    • ifsame database, upto 5
Finally, Multi-Tier users should perform the following test:
  • login to the machine that contains the OpenLink server components.
  • Run oplshut -s on the command-line.
  • Compare the output to the Windows Task Manager or Unix ps -ef.
  • Upgrade server components if oplshut shows fewer processes when compared to the Task Manager or ps.
