RE: Odd handle switching behavior in ILE RPG

["Bob Cozzi" <cozzi@xxxxxxxxx>]

David,

I've never heard of the "System Data Structure"???
I'm going to assume you ment the Program Status Data Structure in RPG
(PSDS) as follows:

D PSDS         SDS
D ...


If this is the case, then what might be happening is the programs are
not ending and restarting. RPG only updates the job, user ID and many
other fields when the program is initially loaded. The only way to
refresh the PSDS is to end the program *INLR=*ON and return to the
caller. Then call the program again.

Subject: Odd handle switching behavior in ILE RPG


I've got an odd behavior when switching user handles in a ILE RPG
program.

My application is a CGI program running under the standard web server.

The program starts out running as current user = QTMHHTTP

I then switch the user id to the user profile specified in REMOTE_USER
environmental variable (for discussion, let's call this user "A") using
the standard API's QSYGETPH and QWTSETP.  This user profile switch is
reflected in job status.

The program then operates as this new user happily.  It calls various
programs, which call procedures in service programs, some of which use
the current user field in the system data structure.  The system data
structures 'Current User' field accurately reflects the correct user
profile ("A").

When the web application is done it returns to the main web cgi program,
who switches the user profile back to QTMHHTTP.

On the next invocation, the REMOTE_USER variable is "B".  Again I call
the appropriate API's and the user profile switch is successful.  Again
the job status reflects the correct user profile.

Once again the program operates as this new user ... and calls programs,
which call procedures in service programs.  HOWEVER, this time when the
program references the system data structure, the current user field
does not have the actual current user "B", but it has user "A".

This is obviously incorrect.

The programs operate in either the default activation group or QILE
activation group.

Any idea why this would happen?

Thanks!

david
