Database Link 11G

With 11G some new features and some releated changes came in picture.
Password is case sensitive in 11g, and so is needed for all the db links.

So for creating a db link b/w 10g to 11g, keep in mind to plece the password in double quotes.

Like:

SQL> create database link 10g_to_11g
connect to apps
identified by "appspass"
using 'DBIdentifier';

Quotes are not needed for db link b/w 11g to 11g.

Note:- DB link is not possible b/w release 8i or lower and 11g.

As a workaround we can have some middle release db and create some dummy user with synonyms of required objects there, with a db link.
And this can be accessed by other compatible releases of db, with again a db link.

  1. Hi,
    but whether this approach is recommended by oracle of having middle release db between 8i and 11g.
