Hi,

I have observed that I am unable to connect database when I change the TNS names alias name.
I am able to connect to the database if I give the tnsnames alias name as BB_BB_SSL.WORLD, but if I change the alias name to someother name e.g bb I am not able to connect

I would like to know if there is something restricting it.

--working
BB_BB2_SSL.WORLD= 
  (DESCRIPTION= 
    (ADDRESS= 
      (COMMUNITY=TCP.WORLD) 
      (PROTOCOL=TCPS) 
      (HOST=xxxxx) 
      (PORT=xxxxx) 
    ) 
    (CONNECT_DATA= 
      (SERVER=dedicated) 
      (SERVICE_NAME=xxxx) 
      (SID=xxxx) 
    ) 
  ) 



--Not working
BB= 
  (DESCRIPTION= 
    (ADDRESS= 
      (COMMUNITY=TCP.WORLD) 
      (PROTOCOL=TCPS) 
      (HOST=xxxxx) 
      (PORT=xxxxx) 
    ) 
    (CONNECT_DATA= 
      (SERVER=dedicated) 
      (SERVICE_NAME=xxxx) 
      (SID=xxxx) 
    )


Thank you very much in advance.

Regards,
Pointers

How is this a SQL or PL/SQL question?
With almost 300 posts you still don't know where to correctly post?
I think you should leave the computer world.

I checked the global_names parameter its value is false, I checked in the documentation it is to do with db links

since you decided to not show us exactly what you are doing (& how Oracle responds),
it is not possible to guess what you are doing wrong.

Problem Exists Between Keyboard And Chair
when you use wrong alias, then error gets thrown.

I think i have provided everthing below.

step1:
changed the tnsnames.ora file to below

BB= 
  (DESCRIPTION= 
    (ADDRESS= 
      (COMMUNITY=TCP.WORLD) 
      (PROTOCOL=TCPS) 
      (HOST=xxxxx) 
      (PORT=xxxxx) 
    ) 
    (CONNECT_DATA= 
      (SERVER=dedicated) 
      (SERVICE_NAME=xxxx) 
      (SID=xxxx) 
    ) 


step2: connected to toad and provided usernmae and password and provided database name as 'BB'
and the output is error i.e. ora-12154: TNS:could not resolve the connect identifier specified


step3: changed the tnsnames alias to BB_BB2_SSL.WORLD from BB
and the output is that it is connected to database

I have the below content for sqlnet.ora

# This file is actually generated by netca. But if customers choose to 
# install "Software Only", this file wont exist and without the native 
# authentication, they will not be able to connect to the database on NT.

SQLNET.AUTHENTICATION_SERVICES = (NTS)
