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

Solution Verified - Updated -

Issue

  • Oracle driver raises exception when attempting to create a connection to the database

    ORA-12514, TNS:listener does not currently know of service requested in connect descriptor
    
  • The datasource URL string has the format below1

    jdbc:oracle:thin:@(description=(address_list=(load_balance=off)(failover=on)(address=(protocol=tcp)(host=abc2)(port=1536))(address=(protocol=tcp)(host=abc)(port=1536)))(connect_data=(service_name=abc)(failover_mode=(type=select)(method=basic))))
    

  1. The failure raised by the driver may relate to the exact values in the connection string (e.g. the service name or SID) rather than to the format of the URL
