Silently fail when Licence Server is down

Hello,

I have a batch job which starts DOORS and runs some DXL every hour.

IT take the Licence Server down late every night and have it up sometime early in the morning.

When it is down the "FLEXnet Licence Finder" window appears and needs 'Cancel' clicked.

The batch waits while the window is open, until I arrive in the morning and cancel it.

Is there a way to silently fail and return to the batch if the licence server is down?

You need to:
[1] Understand the rest of this post
[2] figure out exactly which perm is displaying the Flex message (my guess is "errorBox"), and stub override it.

Run the following code:

• ack("FLEXnet Licence Finder is Down")

Compare that to this:

• void ack(string Message)
• {  print "ack:\t" Message "\n"
• }
• ack("FLEXnet Licence Finder is Down")

Or better yet:

• string Cancel[] = {"Cancel"}
• void ack(string Message)
• {  if (batchMode()) //
•    then print "ack:\t" Message "\n"
•    else messageBox(Message, Cancel, msgInfo)
• }
• ack("FLEXnet Licence Finder is Down")

Having said that, "printing" in Batch is a no-no since it leaves DOORS running until in the morning you close the black DOS command box with the printed messages.  You may thus want to change "print" to some kind of "saveBatchErrorMessage" to some file.

Lets not forget about "acknowlege", "errorBox", "infoBox", "warningBox", "confirm", "query"; all of which have two flavors (with or without a parent "DB"), and "confirm" has 4 flavors.

The icon on the display box will likely indicate which perm; a red "X" means "errorBox", a yellow Triangle means "warningBox", a blue circle (with "!") means "ack" or "infoBox" (blue circle with question mark is "query").

Here are the 4 defined "severity" constants:

 int msgQuery  // Severity for messageBox()
 int msgError
 int msgWarning
 int msgInfo

I well understand how to repurpose a function, but it is not a simple dxl modal box. It looks like a normal dxl DB, but I am not convinced it is running as 'interpreted' dxl. It is the error you get when there is no licence, so I guess it is runs as soon as DOORS starts, before any custom dxl is executed. I have checked if the -C dxl runs before it, but it doesn't. I searched for the "Verifying licence..." splash message, but didn't find that either.

Thanks, Adam

I just realised I can test if the server is available in the batch file:

set 
DOORSSERVER=the.doors.server

ping -n 1 %DOORSSERVER% | find "TTL" >NUL: 2>NUL:
if errorlevel 1 (
    echo DOORS Unavailable
) else (
    echo DOORS Available
)

There's a bit of a race condition doing it this way, but probably good enough.

EDIT: Line 1 and 2 should be on one line, but the post gets changed when I save it!?

set 
DOORSSERVER=the.doors.server

ping -n 1 %DOORSSERVER% | find "TTL" >NUL: 2>NUL:
if errorlevel 1 (
    echo DOORS Unavailable
) else (
    echo DOORS Available
)

Or do this:

if not exist "\\the.doors.server\" (
    echo DOORS Unavailable
) else (
        echo DOORS Available, run batch
)
