Installation set-up

At the end of the installation, when the installer has finished writing files and directories, the file security is set up programmatically in the manner described in the following two sections. For both types of system, other users (not specifically mentioned, or in the groups created) are not given any permissions to the grid folder structure.

Windows systems

• A full-access group (<grid-name>_full) is created. The service user is added to this group. The group is given full access to the entire grid folder structure.

• The user running the installer is given full access to the entire grid folder structure.

Linux systems

• The service user and group are set as owner and group, respectively, for the entire grid folder structure. The group ownership is set to be inherited for future files created (this is not possible for the user ownership).

• The service user is given full access (rwx) to the entire grid folder structure.

• The service group is given read access to the entire grid folder structure.

• The umask value of the bootstrap process is set to 027, to ensure that new files created by the process are given the correct permissions.

• The Set Group ID (setgid) mode is set to the entire folder structure.
