TIP 02: Easy Connect Naming Method in 10g by Joel Pèrez

Question

Hi OTN Readers!
Everyday I get connection on Internet and one of the first issues that
I do is to open the OTN main page to look for any new article or any
new news about the Oracle Technology. After I open the main page of
OTN Forums and I check what answers I can write to help some people
to work with the Oracle Technology and I decided to begin to write some
threads to help DBAs and Developers to learn the new features of 10g.
I hope you can take advantage of them which will be published here in
this forum. For any comment you can write to me directly to : [email protected]
Please do not replay this thread, if you have any question related to
this I recommend you to open a new post. Thanks!
The tip of this thread is: Easy Connect Naming Method

Let's go to test it removing the BASE1 service of the listener.ora file
# listener.ora Network Configuration File: C:\oracle\product\10.1.0\db_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = BASE2)
      (ORACLE_HOME = C:\oracle\product\10.1.0\db_1)
      (SID_NAME = BASE2)
LISTENER =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = oracle10g)(PORT = 1521))
  )and Now, I am going to reload the listener service in order to
apply the change to the enviroment.
