Description:

Sometimes there may be a need to install DSM and the DMPrimer component on a different location other than the default location of C:\Program files\CA\DSM.

Default Installation Directories on Windows

  • Default base path
    C:\Program Files\CA\DSM

  • Shared components path
    Shared components are installed in different directories. By default, the Windows Installer creates directories for each of the shared components under the base path:
    C:\Program Files\CA\SC

(If there is any existing or previous DSM installation folder, regardless of where it is located, the new deployment would copy the files to the existing/old folder.)

  • DMPrimer
    C:\Program Files\CA\DSM\DMPRIMER

(If the DMPrimer folder already exists, regardless of where it is located, the new deployment would copy the files to the existing folder.)

Default Installation Directories on Linux and UNIX

  • Default base path
    The default DSM installation directory is:
    /opt/CA/DSM
    The DSM installation directory is also referenced by the environment variable $CA_ITRM_BASEDIR.

  • Shared components path
    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 DSM installation. The installer will honor the existing settings.

  • DMPrimer
    /opt/CA/DSM/dmprimer

Solution:

Windows

The following procedure outlines the configurations required to change the installation path:

  1. In Step7 of the Infrastructure Deployment Wizard enter the desired path under "Please enter any additional Windows install options".
    Ex: CA=D:\test CASHCOMP=D:\DSMR11\SC

    *Note: For folder names that contain spaces, use a '\' before the double quotes as shown below:
    CA=\"D:\Program Files\CA\"

    The "\" is only required for installation of dmprimer.
    The "\" is not required for installation of other components.

  2. Click on "Show Advanced Options". At "Please enter any additional parameters to be passed to the primer installation", enter the desired path. Ex: CA=D:\DMPRIMER

Linux and UNIX

  1. In Step7 of the Infrastructure Deployment Wizard enter the desired path under "Please enter any additional Windows install options".
    Ex: /RCA_ITRM_BASEDIR=/home/CA /RCASHCOMP=/home/CA

  2. Click on "Show Advanced Options". At "Please enter any additional parameters to be passed to the primer installation", enter the desired path. Ex: /RCA_ITRM_BASEDIR=/home/CA/dmprimer /RCASHCOMP=/home/CA

***Note: A symbolic link named 'installer' will be created under the /opt/CA folder. The behavior is by design and cannot be modified.
