Up to V2R1, the AS/400 could only vary off a display device after so many invalid sign-on attempts. This is fine in most cases, but it can be dangerous. For example, suppose you just ended all subsystems. Your AS/400 is in a restricted state (another way of saying, it's dedicated).
In a restricted state, only the system console remains active. If you sign off (or the system times out your job), you must sign on again. Now you make a mistake and enter the wrong password repeatedly--causing the system to vary off the console. No display stations remain active; you have to IPL from the control panel to regain control. Not an attractive thought, is it?
System value QMAXSIGN has always controlled how many invalid sign-on attempts are allowed or, actually, upon which invalid sign-on attempt the system will vary off the offending display station.
Now there's system value QMAXSGNACN (maximum sign-on action), which can have three different values:
'1' system will vary off the display station, as it was before V2R1.
'2' system will disable the user profile.
'3' system will vary off the display station and disable the user profile.
Disabling user profiles is a new feature of V2R1. When a user profile is disabled, the user cannot sign on even if supplying the correct profile name and password. The user profile can be disabled either automatically (as a result of several invalid sign-on attempts) or manually (with the CHGUSRPRF command). The user profile remains disabled until another user runs CHGUSRPRF to change it from STATUS(*DISABLED) to STATUS(*ENABLED).
Business users want new applications now. Market and regulatory pressures require faster application updates and delivery into production. Your IBM i developers may be approaching retirement, and you see no sure way to fill their positions with experienced developers. In addition, you may be caught between maintaining your existing applications and the uncertainty of moving to something new.
IT managers hoping to find new IBM i talent are discovering that the pool of experienced RPG programmers and operators or administrators with intimate knowledge of the operating system and the applications that run on it is small. This begs the question: How will you manage the platform that supports such a big part of your business? This guide offers strategies and software suggestions to help you plan IT staffing and resources and smooth the transition after your AS/400 talent retires. Read on to learn:
