We are having an issue with the environment we are upgrading to v7 r2. Specifically it looks like the issue is with the toolkit and COBOL programs in our HR application. Finance seems to be working fine and uses a different method for calling COBOL programs on the i. This is how finance is calling: $ret = i5_program_call($prog, $this->params, $this->retvals); prams is an associative array of key value pair and retvals is an array of key and empty values. This is how HR is calling: $rawData = $this->_toolkit->PgmCall($programName, "" , $params); Where params is an object from the toolkit with an array of objects with protected properties. Presently the HR programs are working without issue on all of our v7 r1 system but returns an empty string on the v7 r2 server. Any idea what the problem could be? Attached is the toolkit log for the new server.
