The product software uses the InstallShield program to install and uninstall products. For RHEL/CentOS, you invoke the uninstallation program from the system prompt. Failure to use the appropriate method will result in an unstable system and/or inconsistent product directories.
Also, if you plan to reinstall the product, save all of the customized files that are in the BASEDIR/smarts/local directory before performing the uninstallation. The uninstallation program will remove all of the files and directories in the BASEDIR/smarts directory, and then remove the directory.
