Re: Retrieving remote IP address -- MIDRANGE-L

Just had a thought - unusual for this early in the day - the batch job is not the one that is connected, so it has no IP address associated with it. The job with the IP address would probably be the one that submitted the batch job. This information is available to the job itself. So one needs to determine the submitting job (RTVJOBA or an API, I think), then run that submitting job info through a list of IP connection jobs. Eh?

Maybe you can use the API  QUSRJOBI and its format JOBI0600.  This only
needs the job information to return the IP address.

I use this in my WRKODBCJOB program (

The netstat API should be QtocRtvNetCnnDta You need to provide the IP
Address and the port number to get the Job information back.
