Setting Permissions and Ownership

This topic is part of General Considerations in Planning Your Siebel Deployment.

• You can install server-based Siebel products either as the root user or as a nonroot user. For additional issues related to installing as the root user or as a nonroot user, see:
  • Requirements for Siebel Enterprise Server Installation and Configuration
  • Requirements for SWSE Installation and Configuration
• Before installing any server-based Siebel products, 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. 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.

• 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.

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