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This issue is caused by a missing or outdated libstdc++.so.6 as required by the keycheck application (R2011a) or the MLM vendor daemon (R2011b).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

Server has no node list when executing pbsnodes -s

If you see this error "Server has no node list" when you execute "pbsnodes -s 192.168.1.1" (your torque server DNS or IP), it is due to the missing "nodes" file that was supposed to be at /var/spool/torque/server_priv/

The node file should show something like this

## This is the TORQUE server "nodes" file.
##
## To add a node, enter its hostname, optional processor count (np=),
## and optional feature names.
##
## Example:
##    host01 np=8 featureA featureB
##    host02 np=8 featureA featureB

compute-c01     np=12
compute-c02     np=12
compute-c03     np=12

Restart the pbs_sched and pbs_server services

# service pbs_server restart
# service pbs_sched restart
