Hi ALL,
12c/OL6
9i/OL4
We still have old database 9i which soon to be retired.
To be able to retire it we need to migrate 12c.
We have installed 12c and create db_links to 9i, to extract some data from it.
But when I test it, I got error below
SQL> select instance_name from v$instance@OLD_PROD;
select instance_name from v$instance@OLD_PROD
*
ERROR at line 1:
ORA-03134: Connections to this server version are no longer supported.
Is there workaround for this?
Please help.....
Kind regards,
jc
