i am getting this error ORA-12521 after rebooting the system
this problem only in Node1,Node2 is working fine there is no error with the same configuration
but only getting error on Node1.
it starts work but when i reboot the system then its throughing the following error
and i search alot and did the same what was mentioned in those documents.
somewhere i read its just temporary error but if its temporary then why its giving the same error all the time on my Node1?
