Setting Permissions and Ownership

• Before you install each server component discussed in this guide, set umask to 027 on the installation directory of that machine. Changing this setting eliminates other permissions, including group write permissions.

  This action also sets the default permissions, so that all files and directories created afterwards have rwxr-x--- permissions.

  Siebel Service Owner should have all permissions. However, the group should have read and execute (for directory access) permissions only.

• Before installing any Siebel server software, a user with root permissions must create the directory /var/adm/siebel. This directory is different from the directory into which the Siebel products are installed and must be created for every Siebel product that uses the Siebel installer. The user running the Siebel installer must have write permissions to this directory or the installation fails.

  If the /var/adm/siebel directory structure does not exist, the installer will try to create it. Because it is not recommended to install Siebel products as root, a user with root permissions must first create this directory and verify that the correct permissions are set for the installer to write to this directory.
