The Oracle adapter is not connected to the solution

Author: Vashon

Oracle's developer connection is not reported incorrectly: listener does not currently know of SID given in Connect descriptor solution:

In D:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN find the Listener.ora file, the modified file in the "below", copy and overwrite the OK.

# Listener.ora Network Configuration File:d:\app\administrator\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

Change the configuration in the Listener.ora to the following:

Sid_list_listener =
  (sid_list = (
    Sid_desc =
      (sid_name = Clrextproc)
      (oracle_home = D:\app\ Administrator\product\11.2.0\dbhome_1)
      (program = extproc)
      (Envs = "Extproc_dlls=only:d:\app\administrator \product\11.2.0\dbhome_1\bin\oraclr11.dll ")
    )


    (Sid_desc =  
      (global_dbname = ORCL)  
      (Oracle_home =  D:\app\Administrator\product\11.2.0\dbhome_1)  
      (Sid_name = ORCL


)) LISTENER =
  (description_list = (
    DESCRIPTION =
      (address = (PROTOCOL = IPC) (KEY = EXTPROC1521))
      ( Address = (PROTOCOL = TCP) (HOST = localhost) (PORT = 1521))
    )


Adr_base_listener = D:\app\Administrator

If you follow the above or the connection is not, it may be your SID error.
