Hi guys,
I am migrating my oracle 7.3.2.1 database to Oracle 9i.I have three instances namely acc,hacc and tacc.
Connect string used to connect to 7.3.2.1 db was 2:acc,2:hacc &2:tacc and this is working well with 7.3.2.1.
ie. sqlplus acc/acc@2:acc is working.......
if we use the same connect string in 9i it won't work.This is working if we remove 2:
Could any one tell me what is the significance of 2: in the connect string in 7.3.2.1 and is it really not required in 9i?
Immediate response is always appreciated.

Regards,
Sudheer

This is old syntax for sql*net 2.1/2.2 where 2: was indentify of protocol TCP/IP
