Hi I am planning to upgrade one of the Oracle 9i Rel1 to 9i Release 2. I have Multimaster Replication setup in 9i Release 1[ Oracle advance replication and not the streams as Stream is not working in Release1]. Is there any issue while upgrading the database server. I am planning to stop all Push/Purge Jobs on both Database server A and B. Upgrade Master Definition site while keeping Master site for User as both Database server A and B are same copy. After uupgrading MDS, upgrade the Master site and then will enable all Push/Purge jobs. Any issue, comments are welcome so as to build confidence. TIA Sanjay __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
