If Address Windowing Extentions (AWE) support is enabled, a
single instance of SQL Server 2000 can only use a maximum of 50 percent of the
physical memory that is on the computer. Note
This problem only occurs on 32-bit versions of Microsoft SQL
Server 2000 Service Pack 4 that are running on either an x86-based computer or
on an x64-based computer.
For example, if you have a computer that has
16 GB of RAM and AWE is enabled, a single instance of SQL Server 2000 can only
access 8 GB of RAM.
To determine whether AWE is enabled, run the
following script from SQL Query Analyzer:
sp_configure 'show advanced options', 1
sp_configure 'awe enabled'
is set to 1, AWE is enabled on the server.
To view the
behavior, examine the SQL Server: Memory Manager/Total Server Memory
counter in System Monitor. On a computer that is running SQL
Server Service Pack 3 (SP3), this value may be up to the amount of physical
memory that is on the computer. On a computer that is running SQL Server SP4,
this value will never be more than 50 percent of the physical memory.Notes
- This behavior only occurs on computers that have more than
2 GB of RAM.
- If you use AWE memory and you have set the value of the max server memory option to less than 50 percent of physical memory, you will not
be affected by this bug.
- AWE is not available on all versions of SQL Server 2000.
For example, AWE is not available for MSDE, SQL Server 2000 Standard Edition,
SQL Server 2000 Personal edition, or installations of only the SQL Server 2000
- If you are running SQL Server 2000 SP4 on an IA-64-bit
system, you will not be affected by this bug.
This behavior occurs because the total number of usable
buffer pages was based on an incorrect comparison of the number of SQL pages (8
KB) and system pages (4 KB). The problem does not occur on IA-64-bit systems
because the code that makes this comparison is not executed.
