File Access Permissions

If you install the software logged in as root, you might have a problem configuring root read/write access for all hosts on a shared file system. Therefore, you might have problems putting sge-root onto a network-wide file system.

You can force grid engine software to run all grid engine system components through a non-root administrative user account, for example called sgeadmin. With this setup, this particular user needs only read/write access to the shared sge-root file system.

The installation procedure asks whether files should be created and owned by an administrative user account. If you answer “Yes” and provide a valid user name, files are created by this user. Otherwise, the user name under which you run the installation procedure is used. Create an administrative user, and answer “Yes” to this question.

Make sure in all cases that the account used for file handling on all hosts has read/write access to the sge-root directory. Also, the installation procedure assumes that the host from which you access the grid engine software distribution media can write to the sge-root directory.

The name of the root user on Windows hosts depends on the system language of the Windows operating system. You can even change the name of the root user. The default name for many languages is the name Administrator.

If your Windows host is a member of a Windows domain, only the local Administrator is the root user. Neither the members of the Administrators group, nor the domain Administrator, nor a member of the Domain Admins group are the root user. See Appendix B, User Management For N1GE on Windows Hosts for more information about users on Windows hosts.
