#variables can not be exported. In that case, you should modify this script to 
#work in your environment. For example:
#   SAP_SERVER=$SAP_SERVER; export SAP_SERVER; (Correct for Bourne and Korn shells)
#   can change into
#   setenv SAP_SERVER $SAP_SERVER; (Correct for C shell)

#These environment variables are created by NetBackup (bphdb)
