System Commands across a Network

Hi I have a multiple servers each running the same application and the using the same database ( structurally ). I have set up the .rhosts file on each machine and can connect to any of the machines using dbaccess. The username and password is identical on all the machines. Each machine is running 7.30UC3 and AIX4.2 I have a stored procedure do_command() which basically executes a Unix command. If I login to machine a connect to a database and execute the SP everything works fine. If I go to a different machine and through dbaccess execute the following DATABASE someDB@machineB; EXECUTE PROCEDURE do_command(); I get Connected to the new database successful and the SP fails with 668. I know 668 is often just thrown up for reasons other than those specified in finderr 668 but I have also started debug file and traces on the SP. I am not sure if I have missed anything in the network configuration but everything else seems to work fine. I can connect to any machine and run any SP provided the SP doesn't have a SYSTEM statement. Any ideas???
