I was busy installing course images today. One of the technical guys brought a copy of the Oracle 9i DBA handbook, just in case I needed it ;-). Out of interest, I flicked to (I think) aroundabout page 78 where Looney and Whassername discuss RACs.

I wish I could quote it verbatim. At the top of the page, they discussed the "CLUSTER_DATABASE_INSTANCES" parameter... and said "set this to the maximum number of DATABASES you think you'll need." They then proceeded to confuse 'databases' and 'instances' for an entire paragraph. I wouldn't have minded so much, except the parameter name itself makes it abundantly clear what we're talking about.

Then the piece-de-resistance was their "Handy Tip": 'Note: only one undo tablespace may be active at a time in a database'. This in a section dealing specifically with RACs, and -as I hope we all know- each Instance requires its own active undo tablespace, so in a cluster it's *compulsory* to have MORE than one undo tablespace active in the shared database.

Frankly, I couldn't believe it. I knew Looney was bad, but I hadn't realised he (and his reviewers) were quite *that* bad.

Oracle Press = "Beware".
