Watch out for negative side effects of the /3GB boot.ini switch

This link will take you to the MS article on Exchange Server configuration for Exchange SP1.

Mentions the /3GB switch and /userva=3030 /userva=2970



Also why are you using the Copy or Xcopy commands? To move the DB files. You should use eseutil /y option as this uses a more efficient methord by creating its own large buffer thus avaiding the pagepool problem and speeds up the process by about 1/3rd.

loose translation from sp1 readme and post to techrepublic comments on article on /3GB switch.

The information was in the SP1 Readme

"Event 9665: Update to recommended memory settings for running Exchange Server 2003 SP1 on Windows Server 2003.
When you are running Exchange 2003 SP1 on Windows Server 2003 with more than 1 GB of RAM, it is recommended that you set the SystemPages registry key to zero. This recommendation contrasts with the recommendation for Windows 2000 Server, which is to set SystemPages to a value between 24000 and 31000.

The recommended memory settings for Exchange 2003 SP1 on Windows Server 2003 with more than 1 GB of RAM are as follows:

If you host mailboxes or public folders on a server with more than 1 GB of RAM, make sure that the boot.ini file contains the /3GB switch.
When you use the /3GB switch, add the /userva switch to the boot.ini file and set the switch to a value between 2970 and 3030.
When you use the /3GB switch, set the hexadecimal value of the following registry key to 0x00040000:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\HeapDeCommitFreeBlockThreshold
Set the decimal value of the following registry key to zero:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\SystemPages
If you set SystemPages to the Windows 2000 Server recommended value of between 24000 and 31000, an Event 9665 will appear in the event log.
