Summary of AIX ha switch script issues

(1) The use of the HA switch script, stop the database script and start data script at the end of the need to add the statement "Exit 0" (ha switch when the HA script will check the switch script, ha switch script return value of not 0 will be an error.) Ha switchover failed. You can view the HA log log to find the error message).

(2) The use of the HA switch in the script to use the absolute path, otherwise error (can view the HA log log to find the error message).

(3) The script needs to specify the execution user before the non-root user command, or a few commands with "" wrapped in front plus the execution user, for example:

Su-db2inst2-c "db2pd-;d b2stop force;db2pd-"
