DB2 start on AIX 5.2 and AIX 5

Problem: You are trying to open the databases from the DB2® Control Center on the AIX® Version 5.2 or AIX Version 5 platform, and a communication error message appears. DB2 generates this error if DB2 is not started.

Solution

  • Start DB2.
  • If an error occurred during DB2 startup, run the following DB2 command (as root) to refresh, renovate, and update DB2 :
    /usr/opt/db2_08_01/instance/db2iupdt <instance_owner_ID>
    su db2inst1
    db2start
