We were seeing below error when trying to start an instance.
ORA-00119: invalid specification for system parameter
REMOTE_LISTENER
ORA-00132: syntax error or unresolved network name '<scanname>:1521'
ORA-00132: syntax error or unresolved network name '<scanname>:1521'
After doing some research I found that an entry of SQLNET.ORA
was not properly set.
The location of SQLNET.ORA is <DB Home>/network/admin.
NAMES.DIRECTORY_PATH
entry of SQLNET.ORA was wrong.
It had
the entry "names.directory_path = (TNSNAMES)" instead of "names.directory_path
= (TNSNAMES,EZCONNECT)"
So, I
made the change as "names.directory_path = (TNSNAMES,EZCONNECT)"
After
making the above change I was able to start the instance of RAC without any
errors.
