Error description

  • In a DB2 HA(TSA) environment, where partition 0 has designated
    failover nodes, the db2VXX_monitor.ksh script may falsely report
    that partition 0 is "Online" on one of its failover nodes. This
    causes the partition to be automatically stopped by TSA.
    
    There is a small window of time whereby the "ps -u" command will
    capture the "[db2sysc]" process in its output and falsely
    interpret it as partition 0's "db2sysc" process. The "[db2sysc]"
    process temporarily appears in the "ps -u" output after a
    partition's "db2sysc" process spawns and terminates one of its
    child processes.
    

Local fix

  • Modify the appropriate db2VXX_monitor.ksh script so that it uses
    db2gcf instead of ps to monitor partition 0's status, i.e. make
    the following change:
    
    if [[ $NN -ne 0 ]]; then
       bypassHomeDir=TRUE
    fi
