License manager version required for R2019b

Hi, we are currently on v11.16.2. When I go to the license file download page, I get a message that tells me I need to upgrade my license manager. The link at that page takes me to a page to download 11.16.2.1. Is that version of license manager required for matlab R2019b? I do not wish to change the license manager unless it is required for the latest version.

thanks,

Did you ever get an answer to this question? We also have problems using an older license server with a newer license file. It worked (and still works) fine for Matlab R2019a but we cannot start Matlab 2019b despite upgrading the license file.

Hi,

Same problem here.

New MLM vendor daemon, new FlexLM lmgrd/lmutil 11.16.2.1 and new R2019b licensefile, but no go.

(lmgrd) MLM exited with status 1 signal = 17

(lmgrd) Since this is an unknown status, license server manager will attempt to re-start the vendor daemon

and it just keep repeating itself.

If I do an lmstat I get "Network connect to THIS_HOST failed (-95, 378).

Had to rollback to earlier version R2019a :/

Ok.

I have now solved my problem.

The new MLM vendor-daemon is not compatible with RHEL7.7 (the docs say its compatible with RHEL7.3 and higher).

The incompability is due to RHEL7.7 does not provide the correct minversion of libstdc++. Rhel 7.7 provides GLIBCXX_3.4.19 but MLM requires GLIBCXX_3.4.20 and GLIBCXX_3.4.21.

The required file is contained in the download in /sys/os/glnx.

So:

$ sudo vi /etc/ld.so.conf.d/matlab_mlm.conf

add (correct to the path were you have your libstdc++.so.6/libstdc++.so.6.0.22 files)

/opt/matlab/sys/os/glnx64

do:

$ sudo ldconfig

and restart the whole thing and you should be good to go with MLM: UP v11.16.2
