I checked, that the result of the rsh depends the user who execute rsh.
So, If I execute rsh from my CI to my DB with blpadm works fine:
blpadm> rsh adonisdb -l blpadm echo $ORACLE_SID
BLP
blpadm> rsh adonisdb -l blpadm echo $PATH
/usr/j2se/jre/bin:/usr/bin::/usr/sap/BLP/SYS/exe/uc/sun_64:/usr/sap/BLP/SYS/exe/run:/export/home/blpadm:.:/usr/ccs/bin:/usr/ucb
But, in db13 I continue with the same problem, seems it can not "see" the enviorment
