IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1
Adjust maximum resource settings for the operating system
You can change the ulimit settings to avoid running out of file handles, sockets, or memory. If you are receiving error messages related to file handles, sockets, or memory, or if you think there might be a high possibility of this happening, for example if your environment is running multiple instances of IBM WAS, you can change the ulimit settings.
To change the ulimit settings:
- Log in as Administrator.
- Click Start > Run then enter regedit.
- Click HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Services for UNIX.
- Complete one of the following options:
- If a file named MaxOpenFiles already exists in that directory, open it.
- If a file named MaxOpenFiles does not exist in that directory:
- Click Edit > New > DWORD Value.
- Enter MaxOpenFiles for the name.
- Open MaxOpenFiles.
- Change the base to Decimal.
- Enter the Value data. The recommended setting is 2000.
- Close Registry Editor.
- Restart Windows.
- Log in as either Administrator or the installation user. (See Users created prior to or during the installation.)
- Launch a Korn shell window: Start > Programs > Windows Services for UNIX > Korn Shell.
Do not use an already existing Korn shell. Instead open a new Korn shell window.
- Verify that the new ulimit setting has been set:
ulimit -a
