Hello,
I am trying to install EBS 12.2 with RAC Database. I have completed all pre-req, but I faced an error when installation of db tier.
I reviewed log files and I saw these steps;
Db restore completed successfully, but later I think system try to convert this database to RAC db. And it runs the RACAutoconfig. And here is the config logs error,
[main] [ 2023-12-14 20:38:32.440 EET ] [RuntimeExec.runCommand:229]  Connection paramaters values:
[main] [ 2023-12-14 20:38:32.440 EET ] [RuntimeExec.runCommand:229]       Database server hostname     ==>  XXXXXXXX.LOCAL

[main] [ 2023-12-14 20:38:32.441 EET ] [RuntimeExec.runCommand:229]  ORA-27101: shared memory realm does not exist

It looks like script cannot read the SID name. I checked the TNS_ADMIN location and I found the strange naming.

null_myhostnane samples  shrept.lst  UEBSP_myhostname

Do you have any comment about this error? I cannot find anything on Oracle Support.

Note : I notice the reverse DNS not working in my server. I mean;
nslookup scan-hostname command gives an IP but
nslookup scan-ip command give error message. (it doesn't return result for All private and public IP's )

Thank you for your sharing and your supports.
