Hi Guru's,


My DB Version: 10.2.0

OS : Solaris


I have 2 Database installed on the server one with the name of orcl and one with the name of mz50. When i am trying to connect from client side using toad to orcl i am able to connect to that db successfully but when i try to connect to mz50 DB i getting above mentioned error.

I check the tnsnames file as well as listener file and when i am trying to do tnsping both DB reply

My tnsname file is
ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = blade0)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

mz50 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = blade0)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = mz50)
    )
  )

mz5audit =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = blade0)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = mz5audit)
    )
  )

BSCSPROD =
  (DESCRIPTION =
    (ADDRESS =
      (PROTOCOL = TCP)
      (HOST = 192.168.32.42)
      (PORT = 1521)
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = BSCSPROD)
    )
  )

TSI =
  (DESCRIPTION =
    (ADDRESS =
      (PROTOCOL = TCP)
      (HOST = 172.30.70.245)
      (PORT = 1521)
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = TSIINDIA)
    )
)

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )
listener file is
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /export/home/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = mz50)
      (ORACLE_HOME = /export/home/oracle/product/10.2.0/db_1)
      (SID_NAME = mz50)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = /export/home/oracle/product/10.2.0/db_1)
      (SID_NAME = orcl)
    )


  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = blade0)(PORT = 1521))
    )
