During HA testing, I shutdown one of node of RAC in AIX, after rebooting, the node couldn't join the cluster. I tried to start it manually, but failed with below issue:
exec(): 0509-036 Cannot load program crsctl because of the following errors:
This is due to incorrect setting of AIX IOCP.
- Check if the IOCP installed:
[[email protected] /]# lslpp -l bos.iocp.rte
- Change IOCP setting from
# smitty iocp
- Check the status of IOCP after rebooting
Should be Available status.
[[email protected] /]# lsdev -Cc iocp
iocp0 Available I/O Completion Ports
This is a prerequisite to change IOCP parameter before installing database 12c in IBM AIX environment.
