Performing automated VCS installations

Using installvcs program with the -responsefileoption is useful not only for installing and configuring VCS within a secure environment. This option is also useful for conducting unattended installations to other clusters as well. Typically, you can use the response file generated during the installation of VCS on one cluster to install VCS on other clusters. You can copy the file to a system in another cluster and manually edit the file to contain appropriate values.

When the systems are set up and meet the requirements for installation, you can perform an unattended installation. You perform the installation from one of the cluster systems where you have copied the response file.
