Hi All,

  I have installed Oracle WCC 12c instance along with Oracle 12c Dtabase.

It worked well for first 2 days but its giving error when I start Weblogic Admin Server today

WARNING: Can not connect DB with URL jdbc:oracle:thin:@//localhost:1521/ORCLPDB

java.sql.SQLRecoverableException: Listener refused the connection with the following error:

ORA-12514, TNS:listener does not currently know of service requested in connect descriptor

When I tried to connect Oracle database through SQL Developer its giving the error

Listener refused the connection with the following error:

ORA-12514, TNS:listener does not currently know of service requested in connect descriptor in connect descriptor

Howdy, Stranger!
