RE: Odd handle switching behavior in ILE RPG

["Mark A. Manske" <mmanske@xxxxxxxxxxxxxxxxxx>]

first off, better response might come from the web400 group list;
however -

I have had other "weird" things happen to my cgi apps, cleaned it
up very quickly and easily/though not the most efficiently by changing
my activation group to *new - this cleans up the old "stuff" left
hanging out there.   There are better ways to do this, but I have
been under time constraints and knowledge constraints and have not
had the time to pursue them in detail.

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!
