FlexNet/lmadmin

I haven't seen anything fairly recent about the new version.

We have users in different buildings.  We constantly have problems where a duplicate license is taken.  The users are not actually using two licenses.  I believe what is happening is our network causes Creo to not be able to communicate fully.  The FlexLM software we use can't figure out what's going on so it issues a second license to a user even though they are running only one session.  This causes our available licenses to be used up at times.

I am hoping the new version of FlexNet will fix this.


1. Has anyone had any problems with FlexNet Admin License Server?

2. I haven't yet changed the default time-out in the ptc.opt file.  I will be soon but I wonder what would happen in this situation.  A user has a license and has a modified file.  Doesn't save it but leaves for a meeting.  The license server takes the license back because of the time-out.  But when the user gets back there are no licenses available.  Will the user still be able to save the file?

I also like the idea of web access in the new version since I don't have access to the server.

Re: FlexNet/lmadmin

Hi Steve,

we are using Web license since last year without any kind of issue.

Following David Haigh‌'s presentation I've also modified the default time-out from 7200 to 1200.

This way we have reduced the use of concurrent licenses without causing problems for users, because we have modified also two entries in config.pro to avoid the issue related to the license no longer used for a certain period of time.

Monitoring the use of Creo with Performance Advisor I have not encountered unexpected exits due to the use of licenses.

Re: FlexNet/lmadmin

Thank you Marco.

I had looked at that presentation from David.  That is part of the reason I asked my questions.

I still would like to know what happens in the situation I describe in #2.  Would the user lose their work if there are no licenses available?  I will probably change the time-out value, but that depends on that answer.  I guess it should be ok since there are many, many companies that change it and I haven't heard of anyone saying it's a problem.  However, I am still cautious and want to know for sure what would happen.

Re: FlexNet/lmadmin

It gives you options, SAVE, EXIT, or RETRY (license acquisition).

Re: FlexNet/lmadmin

So even though the license is not available it allows them to save what they have?  Even if they have several files currently open?  That is fantastic if so.

Re: FlexNet/lmadmin

You might want to test it.  I think the save may only be for the currently active window...

Re: FlexNet/lmadmin

Losing a license does not cause the session to end. All unsaved data is still in session and can be saved even without a license. If the user tries to do any work, then he will be prevented from performing that operation until a license becomes available. I know when I get back after being off for a while, I can do 1 or 2 commands before I get the license restored pop-up. I don't have enough users to test using all licenses, but I believe what I described is the proper operation. PTC nor Flexera can afford to have customers lose work because the licenses are all used up. Worse case is the system will force the user to wait for a license.

Re: FlexNet/lmadmin

I would agree with Tom, you should test it. We used to be right on the hairy edge of licenses but that has changed since oil prices have dumped. Now we are swimming in unused licenses and I can't verify. Like Ben said, I've never knowingly been kicked out of pro due to license lost. Sometimes I had to wait till a license became available (or I would boot someone and steal their license, haha, the perks of knowing how to do it).

Re: FlexNet/lmadmin

I would like to test it but it's difficult.  We don't always have all licenses used up or nearly all.  Then you have to wait for a time before all the licenses ARE taken.

Lastly, you have to let Creo wait for the time-out period.  Besides the fact the license might not get stuck, getting that all timed up is not that easy to reproduce it upon command.

I have a batch file that records every 15 minutes the ptcstatus output.  I just updated it to include looking for duplicate licenses then notifies me if there are.  Maybe I can find something out of that data and also by asking the user if they have had any problems with Creo.  I suspect it's our network but I don't know how that would play into the license being stuck on the server.

Re: FlexNet/lmadmin

I have done some more testing.

A couple suggestions was to change the sleep option on the computer to None.  Change the "Turn off the display" to Never.  Changed the screen saver to None and also uncheck the "On resume, display login screen".

Some users had to make either 1, 2 or all three of these setting.  However, there were a few that had these already set that way.  We were still getting flexlm serving an extra license to users.

This is what I did as a test and it is fully repeatable.  I have done this six times since yesterday.  Four yesterday and twice today and it has happened every single time.

Started Creo.

Unplugged the network connection.

Started a CAD part model and created one feature.

Selected to save the file and got the License is lost dialog box.

Selected the Save button.  It finished saving.

Dialog box only has Save, Exit and Retry.  Left it alone.

Waited 15 minutes.

Plugged the network connection back in.

Selected Retry.

Got the message Regained network license.

Finished saving the model.

Checked the PTC status.  I was issued a second license.

We had opened a call with PTC.  I added a comment to the call on the web about this test and they responded within 5 or 10 minutes.  He was transferring the call to a specialist.

Our FlexLM software is 10.8.10
