Thanks Giovanni and Niall. The entry in boot.ini reads : [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Server" /fastdetect /3GB The server has been rebooted since then. And still we start getting 4030 when the Oracle.exe process size reaches around 1.8 GB (shown in perfmon). So it looks like just setting the /3GB flag won't help. I found the following note on Microsoft site which concurs with Giovanni, that the /3GB setting applies to Win 2k Advanced Server or higher. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/memory/base /4gt_ram_tuning.asp Giovanni (or anybody else), have you tried this setting on Wink 2K server? If you are quite certain that this works only with Win 2K Advanced Server or higher, then I will start looking for other options. Meanwhile please send the utility if possible. Thanks & regards, Charu Joshi. -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx]On Behalf Of Niall Litchfield Sent: 18 July 2005 14:25 To: joshic@xxxxxxxxxxxxxx Cc: Oracle List Subject: Re: Win2K /4GT - Request for imagecfg.exe utility Have you verified that you really need this? The earlier note specifically doesn't apply to NT4 and I certainly have never needed to run this tool on Oracle.exe versions. All I have done when experimenting with this is to set the /3GB flag in boot.ini. Does this not work correctly on your version?

Of late we are frequently experiencing ORA-4030 errors, because the Oracle.exe process footprint grows close to 2 GB. I came across metalink notes 46001.1 and 116076.1, which mention a way to configure Win2K OS, so that a process can grow upto 3GB, instead of the original 2 GB. This requires a utility called imagecfg.exe. This is supposed to come with the Server Supplement One CD of Windows 2000 Server. I checked with our hardware people but they don't have the CD. I googled for the utility, but the versions found did not have the '-l' option that is required for this task. So may I request you to send the utility directly to me in a ZIP file archive, if you happen to have it? Also, if you have used this utility before, please care to share your experience.
