  - Install DevOps Code ClearCase® clients and servers
    The method that is used to install DevOps Code ClearCase® depends on the target platform and on your installation strategy.
  - Configuring your environment after deploying
    For some types of DevOps Code ClearCase® and DevOps Code ClearCase MultiSite hosts, you must complete some configuration tasks after you have installed the products.
    - Completing the installation on a license server host
      If you are using the ClearCase® licensing model (called the Atria licensing model), create a license database file on each host that you have selected to be a license server host. This file must contain the license authorization code obtained from IBM®.
    - Completing the installation on a registry server host
      To complete installation of a registry server host, you must create a VOB-tag password file on that registry server host.
    - Verifying installation on individual hosts
      Perform these tasks to determine whether DevOps Code ClearCase® is properly configured for an individual host. On Linux and UNIX systems, enter the commands listed in a shell. On Windows™, enter them at the command prompt.

      - Modifying the search path to include the bin directory
        As part of the post-installation procedures, the search path of each client host environment must include the DevOps Code ClearCase® bin directory.
      - Modify the search path for reference pages
        The standard man and xman commands can locate reference page files in various locations. These programs can use (but do not require) a search path specified by the MANPATH environment variable. If you want to read DevOps Code ClearCase® reference pages using these programs, add the DevOps Code ClearCase man directory to your reference pages search path.
      - Other DevOps Code ClearCase® search paths
        DevOps Code ClearCase® uses configuration files and environment variables to find various other resources that it might require during processing. In particular, some DevOps Code ClearCase utilities need a way to distinguish different file types (text and binary files, for example) or to find a text editor. The graphical tools also need access to file typing data, icons and bitmaps, X Window System resource schemes, group files, and text editors.
    - Set up ACLs on new and existing VOBs
      Before you introduce ACL-enabled VOBs into the ClearCase® environment, complete administrative tasks to prepare the VOB to support and enforce ACLs. The required tasks are different depending on whether you are using a new VOB created in version 8.0.1, or an existing VOB upgraded to version 8.0.1.
    - TLS ciphers
      To ensure a high-security Transport Layer Security (TLS) deployment by default, TLS ciphers are enabled for use by clients and servers according to software standards.

Modifying the search path to include the bin directory

As part of the post-installation procedures, the search path of each client host environment must include the DevOps Code ClearCase® bin directory.

Shell environment Standard installation location (/opt/devops/clearcase) Alternate installation location (/opt/ccase)

.cshrc (C shell)

Table 1. Setting the executable path to include the DevOps Code ClearCase® bin directory
Shell environment	Standard installation location (`/opt/devops/clearcase`)	Alternate installation location (/opt/ccase)
.cshrc (C shell)	`set path=($path /opt/devops/clearcase/bin)`	`setenv CLEARCASEHOME /opt/ccase set path=($path $CLEARCASEHOME/bin)`
.profile (Bourne or Korn shell)	`PATH=${PATH}:/opt/devops/clearcase/bin export PATH`	`CLEARCASEHOME=/opt/ccase PATH=${PATH}:$CLEARCASEHOME/bin export CLEARCASEHOME PATH`

set path=($path /opt/devops/clearcase/bin)

setenv CLEARCASEHOME /opt/ccase
set path=($path $CLEARCASEHOME/bin)

.profile (Bourne or Korn shell)

PATH=${PATH}:/opt/devops/clearcase/bin
export PATH

CLEARCASEHOME=/opt/ccase
PATH=${PATH}:$CLEARCASEHOME/bin
export CLEARCASEHOME PATH

Note: The variable CLEARCASEHOME must be set if DevOps Code ClearCase® is installed at a location other than /opt/devops/clearcase.
