Re: [U2] @LOGNAME on Unidata
On Universe you can use SYSTEM(19) instead of @LOGNAME. It might exist on Unidata too. I don't know if @LOGNAME gets it from the Unix environment LOGNAME variable. If so, there may be a Unix script that is changing the environment variable.

Re: [U2] @LOGNAME on Unidata
Hi Jeff, While at Beloit I had a problem with @LOGNAME. It only showed up when a Datatel program was calling another Datatel program (or something like that). I know it had something to do with a problem with Uniobjects and PAM authentication. The work-around was to add the DMI username and password in a DMIEXTS record. We used a Datatel subroutine to control access to budgets for reports such as the trial balance report. Turned out the report thought everyone was datatel. Worse yet, at the time we found this out, the user datatel was setup to have wide open budget access. I'm wondering if Datatel's strange world of listeners is involved in your case. On the other hand; going to Unidata 7.2.x was the solution for our budget access problem as I was able to undo the above work-around. --- On Thu, 6/17/10, Jeffrey Butera jbut...@hampshire.edu wrote: From: Jeffrey Butera jbut...@hampshire.edu Subject: [U2] @LOGNAME on Unidata To: U2 Users List u2-users@listserver.u2ug.org Date: Thursday, June 17, 2010, 2:04 PM We recently migrated from Unidata 7.1.8 on Solaris to Unidata 7.2.5 on RedHat.

Re: [U2] @LOGNAME on Unidata
We ran into a similar situation in the past with uv on hpux Although @LOGNAME is documented as a readonly value, we found out that it is possible to change it ( and other readonly system variables ) by passing it as an argument to a subroutine - the subroutine can then change the value. I guess uv doesn't actually mark the variable as readonly in any way at run time - readonliness is a compile time attribute - so a subroutine has no idea that its calling args are readonly system variables - so in effect they aren't. Look for any subroutines called with @LOGNAME as an argument then check that the sub doesn't alter that argument. Given : ... CALL *SOMESUB( @LOGNAME ) ... DEFINE SUBROUTINE SOMESUB ( ARG ) ... * this will change the argument value in the calling routine * including 'readonly' system variables ARG=Something ... END Pass temp variable instead of @LOGNAME : CALL *SOMESUB( @LOGNAME: ) -or- CALL *SOMESUB( (@LOGNAME) ) -or- Ensure that argument is never modified in the routine -- DEFINE SUBROUTINE SOMESUB ( ARG.IN ) ARG=ARG.IN ;* the only place IARG is ever used ... ARG=SomethingElse ... END Note that this also applies to functions and routines called via SUBR() and once the variable is changed it is changed for the lifetime of the current session not just for the current program.

RE: [U2] @LOGNAME?
I think @LOGNAME comes from windows which appears to cache it. We found
after changing the user names a reboot of the server was required to
bring in the updated name. We also have a .bat file which does an: ECHO
%USERNAME% but I don't recall which it returned.
For us the reboot was the easiest fix, if you can't reboot perhaps a
secedit /refresh (IIRC) would work?

Greetings all,
Does anyone here know how UniData on Windows sets @LOGNAME.
Where/When does it get set? (UniData 6.1, Windows 2003SE)
We've recently undergone a standards enforcement for NT user
ids and many of my users had their user id changed. When these
users use a process that checks @LOGNAME (from BASIC) to
determine who they are their old user id is returned.
I thought perhaps UniData might have stored some trace of the
old IDs in the user's registry but logging on a new machine
produces the same result.
I also thought perhaps UniData might cache Windows credentials
and forcing a password change might trigger an update but that
didn't help.
I'll try a server reboot after the close of business but if
that doesn't work I'm not sure what to try next. I have
considered using
GETENV('USERNAME') to return the ID I'm expecting (which works
btw) but that means changing a slew of programs and I'd prefer
not to do that.
Any information on this would be really helpful.
Thank you,
Eric Neu
