Issue while running job in HPL

I am using Informix Dynamic Server 9.40.FC9W2XH on HP-UX B.11.23 U. I am facing the below error while running a job for unloading a table using HPL: $ onpload -j j_air_dd_details -fu -l air_dd_details_1.log -i 100 -R $PWD/aifx_gethostbyname(target host) failed While creating the job, the session table in onpload DB gets updated with all the details except for field "hostname" which is updated by the value "XXXXXX". From where does the value of "hostname" is reflected in the table and how can it be rectified so that the actual value of hostname gets updated? Kindly help.
