DB2 Database background processes stop unexpectedly

Solution Verified - Updated -


  • We have two DB2 HADR clusters that have had background processes no longer starting after the OS was upgraded.
  • For both clusters, there were no issues on RHEL5.7. After an upgrade to RHEL 5.9 on both clusters, however, the issue started.
  • This behavior is not observed on any other DB2 database server, only these clusters in production.


  • Red Hat Enterprise Linux, verion 5.8 and up
  • DB2 HADR cluster
