Hi,
Sometimes You can get “TNS-01150: The address of the specified listener name is incorrect ” error.
Details of error are as follows.
TNS-01150: The address of the specified listener name is incorrect
Cause: The address on which the listener attempted to listen contains a syntax error.
Action: For the listener name or service name specified to LSNRCTL, check that the address or connect descriptor is well-formed.
You can find the listener name in LISTENER.ORA, or you can access the listener through the service name is TNSNAMES.ORA.
TNS-01150: The address of the specified listener name is incorrect
NL-00303: syntax error in NV string
NL-00303: syntax error in NV string
This issue was caused by incorrect listener name, check if it is correct or not in the listener.ora under $ORACLE_HOME/network/admin.
And also check if the opening and closing brackets are present in the listener.ora file.
Mostly there is a missing opening or closing bracket in LISTENER for DESCRIPTION, check and fix it, then start listener again.
Listener description should be as follows.
LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = host name)(PORT = 1521)) ) ) my listener ora is as follows.
LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.63.34)(PORT = 1521)) (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) ) ) SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = MSDB) (ORACLE_HOME = /u01/app/db_home_18c ) (SID_NAME = MSDB1 ) ) )
then run the lsnrctl start listener command.
