use tar cvf "archive name" .tar to untar the archive.
then set these variables:
export SOC_HOME=/home/SOC/SOC33.USR2/lnx86
export BINDIR=/home/SOC/SOC33.USR2/lnx86/tools.lnx86/bin
export FEBINDIR=/home/SOC/SOC33.USR2/lnx86/bin
export CDS_PLAT=/home/SOC/SOC33.USR2/lnx86/tools.lnx86/bin/cds_plat
export ENCOUNTER=/home/SOC/SOC33.USR2/lnx86
export SE_HOME=/home/SOC/SOC33.USR2/lnx86/
export PKS_HOME=/home/SOC/SOC33.USR2/lnx86/BuildGates/v05.13
export PLATO_HOME=/home/SOC/SOC33.USR2/lnx86/tools/plato
export CADMOSHOME=/home/SOC/SOC33.USR2/lnx86/tools/fe/celtic
u may need to modify the above according to ur install path.or in order to use the same variables just rename the directory where u untarred the contents if soc archive to "SOC".copy all these variables to your .bashrc in your root directory.
