I am migrating my oracle 18.104.22.168 database to Oracle 9i.I have three instances namely acc,hacc and tacc.
Connect string used to connect to 22.214.171.124 db was 2:acc,2:hacc &2:tacc and this is working well with 126.96.36.199.
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 188.8.131.52 and is it really not required in 9i?
Immediate response is always appreciated.
