Hi,

Sometimes You can get “ORA-12529: TNS:connect request rejected based on current filtering rules ” error.

 

Details of error are as follows.

ORA-12529: TNS:connect request rejected based on current filtering rules
Cause: Connection Manager and its listener were configured with filtering rules specifying that the connect request be rejected.

Check your Hostname, Port, DB Name and fill them correctly.

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 )
)
)


[o[email protected] ~]$ lsnrctl start LISTENER

 

Or Restart database and listener.
