The structure of the installation directories of CA ITCM in Linux and UNIX environments, and the rules and restrictions that apply to them, are described as follows:
The default CA ITCM installation directory is:
/opt/CA/DSM
The CA ITCM installation directory is also referenced by the environment variable $CA_ITRM_BASEDIR.
You can change this default base path when prompted.
Shared components are installed in different directories. The Installer creates directories for each of the shared components by default under the base path:
/opt/CA/SharedComponents
The common components location is also referenced by the environment variable $CASHCOMP, which is set up by the Installer.
Note: $CASHCOMP is shared by all CA products on a computer. If this value has been set (by installing another CA product previously), it will not be possible to change it in the CA ITCM installation. The installer will honor the existing settings.
You can specify whether you want the system-wide PATH environment variable to be updated or not at the end of the installation. If you do not, you can still set up the path manually after installation, along with other environment variables required for correct operation of CA ITCM. To do this in a Bourne/Korn/bash shell, run the command:
# . $CA_ITRM_BASEDIR/scripts/dsmenv
To set up the environment in the C shell, run the command:
# source $CA_ITRM_BASEDIR/scripts/dsmenvcsh
