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

 

修改 listener.ora
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/app/ora10g/product/10.2.0)
      (PROGRAM = extproc)
    )
  )

 

修改为如下：

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/app/ora10g/product/10.2.0)
      (PROGRAM = extproc)
    )
   (SID_DESC =
    (GLOBAL_DBNAME = ora9)
      (ORACLE_HOME = /u01/app/ora10g/product/10.2.0)
      (SID_NAME = ora9)
    )
