TechTalk: Automatically move spooled files from one output queue to another.

One morning, you arrive at the office and realize that one of your printers is broken. You need a quick way to redirect spooled files from the output queue of the broken printer to the output queue of a working printer. Sound familiar? I've got an easy way to handle this situation.

I've written a command called Redirect Output Queue (RDTOUTQ) and an associated CL program called RDT001CL. You can see the command and the CL program in Figures 3 and 4, respectively. (Note that the CL program uses the CVTBIN4DEC command from QURSTOOL, so you'll need to create that also.) The command associates a data queue with an output queue and monitors the data queue for new entries.

When a spooled file is in the "from" output queue in a ready status, an entry is automatically placed in the data queue. The program receives the entry and extracts the information necessary to move the spooled file to the "to" output queue. (Spooled files in the output queue in a ready status when the program starts will not be moved. Those files need to be held and then released before they will be moved to the new output queue.) You can submit the command to a multithreaded batch subsystem; spooled files will be moved as long as you leave the job running. As you might imagine, this command could save you quite a bit of time.

  • SB HelpSystems ROBOT GenericIT security is a top priority for businesses around the world, but most IBM i pros don’t know where to begin—and most cybersecurity experts don’t know IBM i. In this session, Robin Tatam explores the business impact of lax IBM i security, the top vulnerabilities putting IBM i at risk, and the steps you can take to protect your organization.

  • 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:
