TNSadmin demo

Launch TNSadmin Manager GUI demo to see, how it can simplify Management of tnsnames in LDAP.

Open TNSadmin Manager GUI in your browser

URL: http://demo.tnsadmin.com
Username: tnsadmin
Password: mypassword

Set your Oracle client and test TNS resolution

You can even try to point your Oracle client to ldap://demo.tnsadmin.com:389 and test out how it resolves your records.
Just modify some Oracle client configuration files

$ORACLE_HOME/network/admin/sqlnet.ora:

NAMES.DIRECTORY_PATH= (LDAP)

$ORACLE_HOME/network/admin/ldap.ora:

DIRECTORY_SERVERS=(demo.tnsadmin.com:389)
DIRECTORY_SERVER_TYPE = oid
DEFAULT_ADMIN_CONTEXT = "dc=tnsadmin,dc=com"

Now, create a record for existing database, and you should be able to connect to it:

C:\>tnsping oradb.tnsadmin.com
