Setting up ccm_root and informix users and groups

User ccm_root and user informix are the two administrative users. You must have these users and groups defined to install Rational® Synergy.

About this task

User ccm_root owns most of the files and directories, and is the user with permissions to run the administrative commands for Rational Synergy. User informix is used by the Informix® software to perform administrative tasks governing the database server activities.

If you are not using NIS, set up ccm_root and informix users and groups on each engine host. Use the same numeric user and group IDs on every computer.

Place the ccm_root and informix home directories wherever appropriate for your site.

Do not install the software into the ccm_root home directory.

Perform the user and group setup as user root.

Procedure

  1. Create the ccm_root and informix users.
  2. Create the ccm_root and informix groups.

    Make ccm_root a member of group ccm_root, and user informix a member of group informix. Group informix must be the primary group for the user informix.

    To the ccm_root group, add the names of any users who have the build_mgr (build manager) role.

  3. If you are running Rational Synergy on a Linux platform, link /etc/logingroup to the /etc/group file.
  4. Create ccm_root and informix home directories. Write the value for ccm_root_home in item 3, and write the value of informix_home in item 4, on the worksheet.
    Note: Be sure that the informix_home home directory is not the same as the informix_chunkfiles directory.

Example

The following examples include /users/ccm_root and /users/informix:

   root# mkdir /users/ccm_root
   root# chown ccm_root /users/ccm_root
   root# chgrp ccm_root /users/ccm_root
   root# chmod 755 /users/ccm_root
   root# mkdir /users/informix
   root# chown informix /users/informix
   root# chgrp informix /users/informix
   root# chmod 755 /users/informix
