The AWE setting is completely ignored on 64 bit.

Thanks,
my question is if it is enabled, is there any disadvantage?

the comment i heard is "This will cause LOTS of page file usage"

is that true? and is that a disadvantage?

>> AWE is not required and cannot be configured on 64-bit operating systems.

>> This feature will be removed in the next version of Microsoft SQL Server. Do not use this feature in new development work, and modify applications that currently use this feature as soon as possible.

But that is quite old.

Cursors are useful if you don't know sql.
SSIS can be used in a similar way.

AWE has absolutely NO effect whatsoever on a 64-bit instance. No effect, no behaviour changes. It's completely ignored by the engine.
