Recently I was upgrading one of our database from 10.2.0.4 to 184.108.40.206. When we setup everything and executed the runInstaller then Installation screen freezes for some time and thrown error “[INS-30131- Initial setup required for execution of Installer]”. This Issue was encountered on machine running AIX 6.1 – Power processor.
There was a special characters exists in hostname “test_server1” which is not supported.
– Please remove any special characters in server hostname. Special characters are not supported in Oracle Database 12c. So make sure that there is no special character exists in server hostname.
If you are Installing and creating a new database then its not a big concern, still there is a room to change hostname. But this was not applicable in my case. The database hostname was hard coded in too many application files and its really difficult to change it. We have to rollback the hostname with special character after completion of upgrade. So far its working good.
I highly recommend not to use special characters while configuring the hostnames for database and cluster machines.
