What Do I Do If My Broker Shuts Down Intermittently?

Most intermittent shutdowns share a common origin. Users have copied a single license to one or more machines on a network. Users can not do this. Instead, users must obtain individual licenses for each Multi-Tier server component installation. If the problem persists, apply standard stability troubleshooting guidelines.

  1. Patch databases and operating systems, as appropriate.
  2. Contact database and o/s vendors to see if patches are associated with problems.
  3. Insure Unix kernel tuning parameters match parameters specified by database and o/s documentation.
  4. Insure your machine has adequate memory and processor resources.
  5. Insure PortHigh is 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.
  6. Multi-Tier users 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.
  7. Multi-Tier users experiment with database agent reuse. Users should comparison test the following values:
    • ifsame process, upto 5
    • ifsame application, upto 5
    • ifsame database, upto 5
