Re: Users API


Hi Douglas,


I have been looking at a whole host of api's and so far haven't found the
one I need.  We need to build a subfile list of all available, active users
on the system for use in an internal security mechanism.
What defines a user as "available and active"? Do active batch jobs count, or just interactive jobs? I'm not sure what "available" means in this context, either... is that a user who is sitting on a menu? Or running a program? (Or unmarried? heh.)
If you're looking for a list of the users who are signed on, try the List Signed-On Users (QEZLSGNU) API.
If you're looking for a list of active jobs, try the List Job (QUSLJOB) API. 



I thought QUSRTVUI would work but apparently it is object driven.



No, that's not related to user profiles.  That API is for user indexes.
You know how keyed files work? They retrieve records using "key values" that are looked up very quickly in a file. The way they can take a key value and find it so quickly is by looking that key up in an "index".
What if you wanted to make your own indexes? Ones that aren't part of a file, but just keys that you use for some other purpose. Maybe your program has an array or subfile and wants keyed access to it, so it wants to build an index over the data.
IBM makes indexes available to user-written programs (as opposed to the operating system itself) using special objects named "user indexes" and special APIs called "user index APIs". QUSRTVUI is one of those APIs.
QUSRTVUI has nothing whatsoever to do with user profiles or who is logged on to your system.
