Anyone who has used group jobs regularly has undoubtedly issued a signoff just as he or she remembered that another job in the group was already active - like Order Entry, a job that is not always easy to restart. When this happens, the other job is ended abnormally. To recover you would probably need to go into a system control file and change the flag that says Order Entry is active. This is relatively simple, but it takes take time, and in this world, time is money!

To prevent a signoff from making your life more difficult, I have written a simple command and command processing program, both called SIGNOFF (Figures 1 and 2). It works by checking to see if the job from which you are signing off is a group job. If it is, the command will end only the current job and switch you to the previously active group job.

After entering these two source members, compile them into a library that will be placed ahead of library QSYS in your system library list. I use QSYSMODS to contain commands that I want to use in place of OS/400 commands. Even the most conscientious people can forget. So next time you arbitrarily type in signoff, be assured that you don't have to worry about that group job that you started earlier.

  • SB HelpSystems ROBOT GenericCan you trust all of your users all of the time? A typical end user receives 16 malicious emails each month, but only 17 percent of these phishing campaigns are reported to IT. Once an attack is underway, most organizations won’t discover the breach until six months later. A staggering amount of damage can occur in that time. Despite these risks, 93 percent of organizations are leaving their IBM i systems vulnerable to cybercrime. In this on-demand webinar, IBM i security experts Robin Tatam and Sandi Moore will reveal:
