How to Enable the "/largeaddressaware" Flag for the WebLogic Server Windows Service (Doc ID 1468823.1)

Last updated on AUGUST 12, 2021

Applies to:

Oracle WebLogic Server - Version 10.3.1 and later
Microsoft Windows (32-bit)
Microsoft Windows (32-bit) - OS Version: 7


The C++ flag /LARGEADDRESSAWARE enables applications to handle addresses larger than 2 gigabytes. By default, this flag is not set for the WebLogic Server Windows service started by beasvc.exe, which means that servers running as a Windows service on a 32-bit system are limited to a heap size of approximately 1.5GB. This article describes how to enable the /LARGEADDRESSAWARE flag for beasvc.

NOTE: The Java SE JDK does not support the /LARGEADDRESSAWARE flag, so this article applies ONLY in cases where the JRockit JDK is being used.
