Q. I was very interested in Ernie Malaga's article, "Easy Software Distribution," which was printed in the February issue. When I tried to take advantage of the Load Run (LODRUN) command, however, I realized that I needed to let my QINST-

APP program know the name of the tape or diskette device specified in the LODRUN command. How is this done?

A. Your QINSTAPP program receives the device name in a 10-byte character parameter, which is the only parameter received by QINSTAPP. The program can then use this device name to perform restore operations from the tape or diskette supplied. For example, the QINSTAPP program listed in 7 restores a library called SOFTWARE.

A. Your QINSTAPP program receives the device name in a 10-byte character parameter, which is the only parameter received by QINSTAPP. The program can then use this device name to perform restore operations from the tape or diskette supplied. For example, the QINSTAPP program listed in Figure 7 restores a library called SOFTWARE.

When you mail a diskette with library SOFTWARE (and the QINST-APP program), the recipient runs the LODRUN command specifying the correct diskette device name for that system, and QINSTAPP will then be able to restore SOFTWARE.

  • SB HelpSystems ROBOT GenericForms of ransomware has been around for over 30 years, and with more and more organizations suffering attacks each year, it continues to endure. What has made ransomware such a durable threat and what is the best way to combat it? In order to prevent ransomware, organizations must first understand how it works.

  • 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. If you’re looking to avoid unexpected downtime or corrupted data, you don’t want to miss this session.

  • 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:
