Oracle Error: ORA-12514
This should be a series of ORA-00119 (TNS: the listener cannot identify the Service requested in the connection descriptor.
After investigation, it was found that the dynamic registration of Oracle instances to Listener was not successful, and listener. ora was modified. In this file, add the following statement for static registration:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = Your Global_DbName)
(ORACLE_HOME =/u01/oracle/product/11.2.0)
(SID_NAME = Your SID )))
After the listener is restarted, the problem is solved.
