I upgraded a 9i install to 11g with only one problem. Database links between 11g and our legacy 8i database are no longer supported. I have to transfer data from 11g to 8i two or three times a day so I thought it might be possible to use 10g express to link the databases. The data would be created in 11g, written to a table in 10g and then written to 8i. (I agree this is not the most elegant solution and I can improve it using advanced queue tables).
Does 10g express support database links to Oracle 8i?
Edit: thanks for the link to the Oracle documentation. Has anyone actually done this with 10g express?
Edit: The 8i database is Oracle8i Enterprise Edition Release 184.108.40.206.0 - Production The intermediate would be the 10g express for windows The origin database is Oracle Database 11g Enterprise Edition Release 220.127.116.11.0 - Production
