I'm considering an upgrade of 11.2.0.1->11.2.0.2 via a transient logical standby. I've found that most concept docs depart from reality, so I'm looking to find some real, step-by-step docs. Looking at this one: MAA upgrade document using Data Guard and Physical Standby (Rolling Upgrades): http://www.oracle.com/technetwork/database/features/availability/maa-wp-11g-upgrades-made-easy-131972.pdf The document does not lend me much confidence. Has anyone done this? Does it work as advertised? Limited downtime is so very attractive. There be dragons? -- //www.freelists.org/webpage/oracle-l
