How much RAM does sql2K EE with AWE set by default? Is it 384MB? And how to
see it by using win perfmon?

|||Actually I believe the default is 256MB.

|||256MB is sql7 and 384MB for sql2000. I'm just not sure if it's the same when
using AWE.

|||The default value in SQL Server 7.0 is 128 MB, and was adjusted up to 256MB for SQL Server 2000. This is documented in SQL Server BOL topic 'Using Startup Parameters':
Specifies the amount of virtual address space (in megabytes) SQL Server will leave available for memory allocations within the SQL Server process, but outside the SQL Server memory pool. This is the area used by SQL Server for loading items such as extended procedure .dll files, the OLE DB providers referenced by distributed queries, and automation objects referenced in Transact-SQL statements. The default is 256 megabytes (MB).
The values are not modified when AWE is enabled. There are no counters in PerfMon to show this value.

|||Thanks for the reply. Interestingly there are different numbers ... Both Ken
Hendson's book and an artical on sqljunkies are saying 384mb for sql2k and
256mb for sql7.

Does this mean that MemtoLeave will come from 2GB which I left for OS and 6GB
is resvered sql BPOOL?
thanks

|||No the memtoleave is always taken from the 2GB of directly addressable
memory for SQL Server. The OS has it's own 2GB. AWE has no bearing on this
and the only thing within sql server that can use AWE memory (or memory
above 2 or 3GB depending on /3GB) is the data cache. Everything else must
come from the directly addressable memory.
