Managing MATLAB Users using MLM options for FlexLM

Step 1: Create a file to mlm.opt

Step 2: Edit your license.dat file

SERVER myMATLABLicense 00000000000000009
DAEMON MLM "/usr/local/MATLAB/R2016b/etc/MLM" port=1708 options="/usr/local/MATLAB/R2016b/etc/mlm.opt"
.....
.....

Step 3: Prepare mlm.opt

# Make user names and host names case insensitive when
# listed in a GROUP or HOST_GROUP.  This is not
# required but it is here to prevent some common errors.
GROUPCASEINSENSITIVE ON


# Define GROUP Users
GROUP MATLAB_BLOCK_USERS user1 user2 user3
GROUP MATLAB_INC_USERS user4 user5 user6


# EXCLUDE Users from MATLAB and selected Toolboxes
EXCLUDE "MATLAB asset_info=111111" GROUP MATLAB_BLOCK_USERS
EXCLUDE "Image_Toolbox asset_info=111111" GROUP MATLAB_BLOCK_USERS
EXCLUDE "Signal_Toolbox asset_info=111111" GROUP MATLAB_BLOCK_USERS


# RESERVE for selected for user1
RESERVE 1 "SIMULINK asset_info=111111" USER user1


# Restrict the number of licenses that can be used on machine "server1"
MAX 4 "MATLAB asset_info=111111" HOST server1


# To exclude ALL features 
EXCLUDEALL GROUP MATLAB_BLOCK_USERS


#Includes a user or pre-defined group of users, etc.
#Anyone not in an INCLUDEALL statement is not allowed to use these features. 
INCLUDEALL GROUP MATLAB_INC_USERS

Step 2: Create an mlm.opt file

where user1 is the username

Step 3: Restart the license server to take effect

Getting `GLIBCXX_3.4.9 not found' when starting the license manager for MATLAB

If you are starting the latest version of MATLAB License Server,  you may encounter this error`GLIBCXX_3.4.9 not found'

For more information do look at MathWorks "Why do I get an error 'GLIBCXX_3.4.9 not found"

According to the mathwork website,

Solution:

This issue is caused by a missing or outdated libstdc++.so.6 as required by the keycheck application (R2011a) or the MLM vendor daemon (R2011b). Both the R2011a keycheck and R2011b MLM vendor daemon require libstdc++.so.6.0.10. Refer to your operating system documentation for information on how to update or install a missing library.

If the necessary version of the library is not available for your Linux distribution it can be copied and installed from the MATLAB installation files following the instructions below:

NOTE: $MATLAB refers to the MATLAB installation location (ex: /usr/local/MATLAB/R2011b)
NOTE: $ARCH refers to the machine architecture (ex: glnx86 for Linux 32-bit or glnxa64 for Linux 64-bit)

If MATLAB is installed in addition to the FlexNet license manager, skip directly to step 3.

1. Create a subdirectory within the MATLAB installation folder as shown below:

[root@localhost ~] mkdir -p $MATLAB/sys/os/$ARCH

2. Copy the libstdc++.so.6.0.10 library from the MATLAB installation files (either an installation DVD or the extracted downloaded installer archive) into the newly created directory:

[root@localhost ~] cp /media/MATLAB_R2011b/bin/$ARCH/libstdc++.so.6.0.10 $MATLAB/sys/os/$ARCH

3. Run 'ldconfig' to create symbolic links to the new library and update the dynamic linker cache:

[root@localhost ~] ldconfig $MATLAB/sys/os/$ARCH
