So a colleague of mine just pointed me to a metalink document (after we had been discussing using AMM with hugepages) that 10g uses ASMM not AMM (not to be confused with ASSM). I was under the impression that Hugepages and AMM (in 10g - actually called ASMM) was incompatible but apparently it is not (though it is incompatible with AMM in 11g). Somewhere along the line I dropped the "S" from ASMM in 10g - I swear I didn't remember it being called ASMM and had to look it up in the 10.2 documentation to really believe it. ASMM and LINUX x86-64 Hugepages Support [ID 1134002.1] I so wanted to argue the point that 10g automatic memory management wasn't compatible with hugepages but according to that note it is. Anyone have a differing opinion or thoughts on the matter? Chris Taylor Oracle DBA Parallon IT&S -- //www.freelists.org/webpage/oracle-l
