You must create an installation directory to install Rational Synergy. The installation directory path is ccm_home, as described in s_r_igu_installation_directories.html#wp955903__wp955907.
The installation directory can be anywhere, and have any name. However, install each Rational Synergy release into a release-specific directory (such as /usr/local/ccm71), then link /usr/local/ccm to your current default release. This installation allows more than one installation of Rational Synergy on a machine, which can be necessary if you are upgrading to a new release.
For example, if you have a previous Rational Synergy installation in the /usr/local/ccm71 directory, install the new version into /usr/local/ccm71, then link /usr/local/ccm to /usr/local/ccm71.
Record the path to this directory in step 5.
