Home -> Community -> Mailing Lists -> Oracle-L -> Re: Oracle on Windows 2000 AS with /3GB flag
Check Metalink. You will find all sorts of docs on /3G
I am surprised to hear it didn't work on the test system.
Watch out for hyperthreading on cpus. This affects alot of hidden parameters. I had to take off the auto sga and decrease my sga target quite a bit.
No not applicable on 64 bit Windows.
I did have issues with /PAE switch and performance.
I am working with Orakill now to kill session vs using alter session kill. I found on windows killing sessions didn't always work and orakill does. I will add my orakill info to my article next week hopefully.

Hello to you all,
I'm planning to activate the /3GB flag on a Windows server running Oracle Database, in order to extend the memory that can be used by Oracle.
The server has the following characteristics:
HP Proliant DL380
2 x Pentium Xeon 3,2 GHz
4 GB of RAM
HP Smart Array SCSI controller
2x36GB SCSI RAID 1 internal discs with 2 logical drives:
C drive for OS
D drive for Logs
4x146 GB SCSI RAID 5 internal discs with 1 logical drive:
F drive for data
Paging size on C drive (2048-4096)
SO: Windows 2000 Advanced Server SP4
The Oracle SGA Target is 1336 MB
I would like to know if there is any special care that I should take, before I activate this flag on boot.ini. I read the Oracle Documentation, but I didn't found any particular aspect.
I'm asking this because I had a bad experience with a test server where with the /3G flag was activated and the Oracle instance didn't startup. I still haven't figured out why.
Thanks for all your attention.
Best Regards,
Ricardo.
