Base Directory: The directory where the Oracle Applications is installed. This is a generic directory. 

                            I will suppose that the Base Directory is /APPS

$ORACLE_HOME (for the database tier): /APPS/db/tech_st/10.2.0

$APPL_TOP:   /APPS/apps/apps_st/appl

$COMMON_TOP:  /APPS/apps/apps_st/comn

$ORACLE_HOME (for the apps tier): /APPS/apps/tect_st/10.1.2

$IAS_ORACLE_HOME (for the apps tier): /APPS/apps/tect_st/10.1.3

$INST_TOP:   /APPS/inst/apps/<SID_localhost> contains certifications, configurations, logs for the servers.
