Ошибка лицензии матлаб - Не ошибается лишь тот, кто ничего не делает!

MATLAB^®
Online Server™ requires you to have valid licenses for both MATLAB
Online Server and MATLAB before you install either. After you have completed installation with valid
licenses, your users can sign in successfully to MATLAB
Online™.

License Service Pod State is Running but Users Cannot Connect to MATLAB Online

When the services are running successfully and can connect with the network license
manager license server, then the status of pods is Running.

However, if the services are having issues connecting with network license manager, the
status of the pods is still shown as Running. This is expected, and it means that the
MATLAB
Online Server is running successfully but is not authorized because it is unable to connect to
the network license
manager.

If the license service is not operational, other services also do not work as expected.
This is because the license service checks out the MATLAB
Online Server license, which in turn allows all other services to run successfully.

Get More Information

Run the following command to get more information, replacing
license-pod-name with the name of your license pod and
your-namespace with the namespace you used for MATLAB
Online Server:

kubectl logs license-pod-name --namespace your-namespace

If you get output similar to the following display, then it is likely that the license
service is unable to check out the MATLAB
Online Server
license.

Possible Issues

MATLAB
Online Server is unable access license server when both servers are on the same
machine

If you installed MATLAB
Online Server and the network license manager server on the same machine, license
checkouts from MATLAB or MATLAB
Online Server cluster might be blocked because the firewall prevents access to the
license server ports.

One workaround is to modify the firewall to enable access to the network license
manager ports. By default, the network license manager listens on ports 27000 and 27001.
For example, to enable these ports in Ubuntu^®, use this command:
```
sudo ufw allow 27000 && sudo ufw allow 27001
```
Network license manager server listening on ports other than 27000/27001

Network policy is enabled by default for the license service, which allows
communicating with network license manager only on port 27000 and with the MLM daemon on
27001. The default policy assumes that the license file has the following SERVER lines:
SERVER <HOSTID> ID=0 27000 DAEMON MLM "<FLEXLM_INSTALL_LOCATION>/etc/MLM" port=27001
If your network license manager server is listening on ports other than 27000 and
the MLM daemon on other than 27001, update the license service override file and then
restart the pod:
networkPolicy: enabled: true egress: ports: - port: <flexlm_port_here> protocol: "TCP"
The network license manager server is using an incorrect or an expired license file
or the network license manager server is misconfigured

Check the network license manager server logs to see details about the reason for
failure. Try to connect to the network license manager server from a local machine using
the following
commands:
```
nc -vz <FelxLM_DNS_NAME> 27000
nc -vz <FelxLM_DNS_NAME> 27001
```
In cases where the network license manager server is using an expired license
file:
- Update the license file. See Update Network License in the Help
  Center.
- Set up both a listener on the network license manager log file and an alert, so
  that you are notified when the license is about to expire.
- If the license service pod is not in the Running state, see Resolve License Service Issues.
- See Resolve MATLAB Pod Issues.

License Checkout Fails Due to Missed Heartbeats

If you are running MATLAB
Online Server on a cloud-managed Kubernetes^® cluster, such as through Azure^®
AKS, the license service might unexpectedly exceed the license checkout count.
Exceeding the license count results in failed license checkouts.

When this issue occurs, the logs for the license service contain several "missed heartbeat" warnings. A heartbeat is when the license
service periodically pings the Kubernetes cluster to confirm that the licenses for the MATLAB
Online Server or MATLAB instances running inside it are still checked out. If the license service misses
a heartbeat, meaning it is unable to connect, the service checks out a new license. After too
many missed heartbeats and license checkouts, the service exceeds the checkout count.

To see if the failed checkouts are due to missed heartbeats, run this command to check the
log for the license service:

kubectl logs license-pod-name --namespace namespace

where:

namespace is the MATLAB
Online Server namespace as listed in the install.config file (default =
"mathworks").
license-pod-name is the name of the pod
running the license service. To get the license pod name, run kubectl get pods --namespace namespace.

If the log contains repeated missed heartbeat warnings, such as the ones shown here, then
the issue is caused by Kubernetes closing its connection to the license service after a period of
inactivity.

To resolve this issue, specify a shorter interval between heartbeat checks.

In the license.yaml and matlab-pool.yaml override
files, set the heartbeatIntervalInSeconds field. If left unspecified, the
default interval is 600 seconds (10 minutes). Setting the interval to 120 seconds is
sufficient to resolve the issue. The minimum interval is 60 seconds, but more frequent
interval consume additional server resources.

The tables show the location of the YAML override files and the values to set.

`matlab-online-server-root/overrides/cluster/namespace/license.yaml`
flexlm: servers: "27000@flexlm.company.com" heartbeatIntervalInSeconds: 120

`matlab-online-server-root/overrides/cluster/namespace/matlab-pool.yaml`
flexlm: servers: "27000@flexlm.company.com" heartbeatIntervalInSeconds: 120

After making these changes, you must redeploy the license and MATLAB pool services. For example:

./mosadm undeploy license
./mosadm deploy license

./mosadm undeploy matlab-pool
./mosadm deploy matlab-pool

This issue generally indicates that the license file is served from the Network License Manager and that there is a problem with the license.dat file on the machine running the Network License Manager. The cause of this error may be due to one of the following:

The Host ID for which the license.dat file was generated is not the Host ID of the machine hosting the Network License Manager.
Missing, corrupt, or incorrect characters in the license.dat file itself.
The system time and date are not set properly. Check to make sure that the date and time are set correctly on the machine before proceeding below.

It is also possible for this error to occur if a network license is attempting to be used in place of an Individual or Designated Computer license. If you are trying to activate MATLAB for a network license, you need either a license.dat or network.lic from the person who maintains the Network License Manager. If a Network License Manager has not already been setup, then it needs to be in order to use the license. Read more information from the link below about the differences between license files types:

What are the differences between the license.lic, license.dat, network.lic, and license_info.xml license files?

The first step is to locate the license file (license.dat) for the Network License Manager. The license.dat file on the server machine is located in:

Where are the license files for MATLAB located?

(where $MATLAB is the MATLAB installation directory)

Please check for the following:

1) Make sure that the Host ID specified in the license file matches the Host ID on the «SERVER» line of the license file. The SERVER and DAEMON lines are added automatically when installing the Network License Manager with the MathWorks Product Installer. They can be added manually if you did not use the MathWorks Product Installer to install the Network License Manager.

Additionally, if the Host ID is not proceeded by «ID=», it must match the Host ID of the machine hosting the Network License Manager. For more information on obtaining your Host ID, see the related solution listed below.

The Host ID of the license file will be in a comment line in the license file. For example:

# BEGIN——cut here——CUT HERE——BEGIN

# MATLAB license passcode file.

# LicenseNo: 123456 HostID: 001122334455

In this example, the Host ID is the MAC address 001122334455. This same MAC address should be in the SERVER line of the license file. For example:

SERVER my-license-host 001122334455 27000

If the wrong Host ID is used in the SERVER line, or if the license file was generated for a different Host ID, this error will occur. Individual licenses use a Host ID that is ID= and the license number. If you have an individual license, this should be the Host ID in the SERVER line. For example:

SERVER my-license-host ID=123465 27000

NOTE: Changing the Host ID listed in the commented section of the license file will not resolve the error. If your Host ID is incorrect, you will need to obtain a new license file generated for the correct Host ID.

2) This error may be the result of having extra carriage returns in your license file. In order to avoid this, ensure that the following strings all begin on a left justified line: #, SERVER, DAEMON, or INCREMENT. Sometimes an INCREMENT line can get wrapped on the end of the preceding INCREMENT line causing it to be omitted.

Хорошо, я написал в службу поддержки MathWorks. И они дали мне ссылку на свой форум, где я нашел решение. Вот:

https://www.mathworks.com/matlabcentral/answers/99067-why-do-i-receive-license-manager-error-9

Мне пришлось пройти весь путь до копирования моего HostID и т. Д., Установить мой логин как root и запустить Matlab с sudo

Но в случае, если ссылка здесь умирает, это из сообщения MathWorks: лучший способ устранить ошибку диспетчера лицензий -9 — повторно активировать MATLAB с помощью клиента активации.

Войдите в свою учетную запись MathWorks.
Выберите правильную лицензию.
Поле имени пользователя должно автоматически заполняться правильным именем пользователя. Оставьте как есть.
Подтвердите информацию об активации.
Нажмите «Готово», чтобы завершить процесс активации.
Перезапустите MATLAB.

По-прежнему отображается ошибка диспетчера лицензий -9?

Имя пользователя в файле лицензии не совпадает
Идентификатор хоста в файле лицензии не совпадает
У вас есть лицензия MATLAB для назначенного компьютера, и MATLAB уже работает под другой учетной записью пользователя на этом компьютере.

Подтвердите свое имя пользователя и идентификатор хоста с помощью клиента активации:

Запустите клиент активации и выберите «Активировать вручную без использования Интернета».
Выберите «У меня нет файла лицензии. Помогите мне со следующими шагами ».
Скопируйте свой идентификатор хоста и имя для входа на компьютер.
Щелкните стрелку назад 2 раза и выберите «Активировать автоматически через Интернет», затем введите соответствующее имя пользователя.
Запустите MATLAB, используя соответствующую учетную запись пользователя.

Для запуска клиента активации требуются повышенные привилегии? Ошибка подключения при автоматической активации? По-прежнему отображается ошибка диспетчера лицензий — 9?

License Manager Error Messages

It can also be helpful to view the FLEXlm log file, lmlog.txt, in the $MATLABflexlm directory. To get more information about a FLEXlm license manager problem, see the FLEXlm End User Manual, available in PDF format in $MATLABflexlmenduser.pdf or go to the GLOBEtrotter Software, Inc. Web site, www.globetrotter.com.

Note
You can also go to the support page on the MathWorks Web site, www.mathworks.com, and find information about a particular license manager error by searching the solution database by error number. For example, to find information about License Manager Error -15, enter «License Manager Error -15» in the search engine.

License Manager Error -2: Invalid License File Syntax

This error message typically indicates that there is a problem in your License File. On client systems, make sure your License File ($MATLABbinwin32license.dat) has the following format.

SERVER host hostID port_num 
USE_SERVER

Note that there should be a carriage return immediately following the USE_SERVER line.

License Manager Error -3: Cannot Connect to a License Server

This error can occur if the SERVER line in your License File is incorrect or missing.

To remedy this error, try the following:

Make sure that the SERVER line in your License File matches the SERVER line in the License File on your license server. On client systems, the License File is $MATLABbinwin32license.dat; on your license server, the License File is $MATLABflexlmlicense.dat, where $MATLAB is the root MATLAB installation directory.

Note
You must restart the license manager after making any changes to the License File on the license server.

Make sure the TCP port number at the end of the SERVER line in your License File is not already being used by another application. On NT systems, run the netstat -p tcp command from C:WINNTsystem32. If the local system appears on the Foreign Address list, then the port number listed is being used. Change the port number on the SERVER line to a port that is not being used. FLEXlm has reserved ports in the range 27000 to 27009. Restart the license manager after making this change.
Make sure that you do not have multiple vendor daemons (mlm.exe) running. Check your FLEXlm log file ($MATLABflexlmlmlog.txt) for the error «Multiple MLM Servers Running».

License Manager Error -5: License Checkout Failed. No Such Feature Exists.

This message usually indicates that you are trying to use a product for which you are not licensed. Check your License File to see if you are licensed to use this product.

If you are licensed for this product, this error may be the result of having extra carriage returns in your License File. To avoid this, make sure that each line begins with either #, SERVER, DAEMON, or INCREMENT.

Note
You must restart the license manager after making any changes to the License File on the license server.

This error can also be caused by tab characters in the License File. Remove these tabs and replace with them spaces.

This error may also be the result of an incorrect system date. If your system date is set before the date that your license was made, you will get this error. See License Manager Error -10: Feature Has Expired to learn how to reset the system date.

License Manager Error -8: Invalid (Inconsistent) License Key

This error message typically indicates that your License File, $MATLABflexlmlicense.dat, has been corrupted. This can happen if the License File was edited or if an e-mail program inserted extraneous tabs or carriage returns in the INCREMENT lines.

One way to check for extraneous tabs and carriage returns is to open your License File in a text editor and view all nonprinting characters. Remove all the tab characters and all carriage returns that are not at the end of a line.

Check that the contents of your License File matches the license data sent you by The MathWorks.

License Manager Error -9: Invalid Host. License Checkout Failed.

If you get this error on a system running an individually licensed MATLAB, make sure you are running MATLAB on the same system it was installed on. The MathWorks locks a license to a particular system.

You can also get this error if you replaced your hard drive or changed the partition on an existing hard drive. To remedy this situation, rerun the installer. At Step 5: Select the Products You Want to Install, click on the More Options... button on the Product List dialog box and select the Update license option. This option updates your license without requiring that you reinstall MATLAB.

You can also get this error if you try to clone a Release 13 installation from one system to another.

License Manager Error -10: Feature Has Expired

This error indicates that one or more of your license keys has expired.

Check the expiration date on each of the INCREMENT lines in your License File. If the dates in the license file have already passed, contact the Customer Service department at The MathWorks (through the Web or through e-mail at service@mathworks.com). When contacting The Mathworks, include your License Number and the Host ID of your license server.

If none of your product licenses has expired, check that your system date and time are correct:

Click on the Start menu.
Choose Settings.
Click on Control Panel.
Choose Date/Time.

License Manager Error -11: License Checkout Failed. Invalid Date Format in License File.

This error indicates that the start date or the expiration date in the License File is invalid. This can happen if the expiration dates in the License File have been changed.

You can also get this error if the space character between the number of users field and the 20 digit encryption code in the INCREMENT line is missing. Compare the INCREMENT lines in your license file with the INCREMENT lines in your original license e-mail. They must be exactly the same.

This error can also occur if the SERVER and DAEMON lines are missing from the license.dat file. The installer adds these lines to the License File as part of the installation process.

License Manager Error -12: License Checkout Failed. Invalid Return Data from License Server.

This error can be caused by your network setup. When the license manager tries to connect to the server, the DNS Server does not find it because it does not add the domain name suffix into the search.

If all of your client systems are having this problem, change the name of the server in the SERVER line to the fully qualified name:

Change the SERVER line in all license.dat files on your network, which are located in $MATLABbinwin32, to have the fully qualified name of the server.
Restart the license manager on the server. (See Starting and Stopping the License Manager.)

If only some of the clients in your network installation are having this problem, edit the TCP/IP Hosts file on your client systems:

Open the file, C:WinNTsystem32driversetchosts
Add the hostname of your license server to this file. You can find your license server information in the SERVER line of your license.dat file.

For example, if your SERVER line looks like this,
- ```
SERVER hostname INTERNET=128.36.2.12 27000 
```
Add the following line to your TCP/IP Hosts file.
- ```
128.36.2.12 hostname 
```

Save the changes to the TCP/IP Hosts file.

License Manager Error -13: No SERVER Line in License File

This indicates that there is no SERVER line in the License File. This line should be added by the installer during the installation process.

To remedy this problem, run the installer again or manually edit the License File, $MATLABflexlmlicense.dat, adding the SERVER line. See License File for information about the format and contents of the SERVER line.

License Manager Error -14: Cannot Find SERVER Hostname in Network Database

If this error occurs on a client system, check to make sure that the hostname on the SERVER line in the license.dat file on your client system matches the hostname on the SERVER line in your license.dat file on your license server. Edit the SERVER line in the client license.dat file, if necessary.

Also, make sure that the server’s hostname, included in the SERVER line, is listed in the C:WINNTsystem32driversetchosts file for Windows NT.

License Manager Error -15: Cannot Connect to License Server

This error message can have several causes but the most common cause is that the license manager isn’t running on your license server.

Verify that both the license manager daemon and the vendor daemon processes, lmgrd and mlm, are running. You can check this via the Task Manager, which can be accessed by pressing the Ctrl+Alt+Delete key sequence. Run these commands on the system on which your license manager is running.

If the license manager isn’t running, see Starting and Stopping the License Manager for information about starting it.

License Manager Error -16

This error indicates that the path to the MATLAB vendor daemon, mlm.exe, is incorrect in your License File DAEMON line. See License File for an example of a DAEMON line.

License Manager Error -18: License Checkout Failed. License Server Does Not Support This Feature.

The most common cause of this error is updating your License File without restarting your license manager. Restart your license manager and then try to start MATLAB. See Starting and Stopping the License Manager.

If you get this error on a client system, but not your license server, the License File on the client probably needs to be updated. Copy the License File from the server onto the your client system ($MATLABbinwin32).

Here are some other possible solutions to this error:

Make sure the INCREMENT lines in your license.dat file are exactly as they appeared in the original license e-mail you received from The MathWorks.
Make sure the DAEMON line in your license.dat file identifies the correct license manager daemons, especially if you have multiple MATLAB installations on your system.
Make sure the TCP port number at the end of the SERVER line in your license.dat file is not already being used by another application. Use the command netstat to show the status of all ports that are in use.

On NT systems, run the netstat -p tcp command from C:WINNTsystem32. If the local system appears on the Foreign Address list, then the port number listed is being used. Change the port number on the SERVER line to a port that is not being used. FLEXlm has reserved ports in the range 27000 to 27009. Restart the license manager after making this change.

Make sure the Host ID or IP Address listed in the commented section in the license.dat file matches the Host ID or IP Address in the SERVER line. If you are trying to run the license manager on a different system than the one that the license was generated for, you will need to get a new License File from The MathWorks.

License Manager Error -21: License File Does Not Support This Version

If you are getting this error on your license server, make sure you have installed the version of FLEXlm included with Release 13. Release 13 License Files will not work with the older FLEXlm versions.

If you have updated an existing license.dat file with new Release 13 passcodes, you still need to install FLEXlm 8.0d from the MATLAB CD.

If you are getting this error on one of your client systems and not on the server, make sure the License File on the client is in the following format.

SERVER host hostname port_num 
USE_SERVER

The SERVER line in the client system License File should be the same as the SERVER line found in the License File on the license server.

Also, make sure you are using your Release 13 license and not a license from a previous release.

License Manager Error -25: License Server Does Not Support This Version of This Feature

This error indicates that you are trying to run MATLAB 6.5 with an old license. You must update your license.dat file with your new license passcodes.

If you do not have your MATLAB Release 13 license, contact Customer Service at The MathWorks.

License Manager Error -39: No License for Feature

You may encounter the following license manager error:

License Manager Error -39
User/host not on INCLUDE list for feature
Feature: MATLAB

This table lists a typical cause of this error with possible solutions.

Possible Problem	Resolution
You are not listed as a user in your options file.	Check your options file and make sure your username is on the `INCLUDE` line for the product you are trying to use. On UNIX computers, the installer creates the options file, named `$MATLABflexlmMLM.opt`.

License Manager Error -83: FLEXlm Version of Client Newer Than Server

This error message usually indicates that the version of the license manager on the client system is newer than the license manager on the server system. When MATLAB starts, the license file is pointing to the wrong version of the license manager.

To correct the problem, change the path of the DAEMON line in your license.dat file. For a UNIX server, the DAEMON line for all license files should resemble this sample (the pathname of your daemon will be different).

```
DAEMON MLM $MATLAB/etc/lm_matlab
```

For a PC server, the DAEMON line for all license files should read

```
DAEMON MLM $MATLABflexlmmlm.exe
```

where $MATLAB is your MATLAB installation directory. After changing your License File, be sure to restart the license manager.

License Manager Error -84: Missing Options File

License manager cannot find your options file.

Possible resolutions:

Make sure the installer created an options file during the installation procedure. The full path of the options file is $MATLABflexlmMLM.opt, where $MATLAB is your MATLAB installation directory. See Setting Up Network Named User Licensing for more information.
Make sure that the DAEMON line in your License File includes the full pathname of your options file. Check the processed License File, $MATLABflexlmlicense.dat. If the DAEMON line wraps onto a second line, make sure there is a line continuation character () at the end of the first line.
Make sure you are listed as a valid user of the product you are trying to use.

License Manager Error -88: License Checkout Failed

This error indicates that your system clock has been set incorrectly. Check that your system date and time are correct. To learn how to change the system date, see License Manager Error -10: Feature Has Expired.

License Manager Error -96: Server Node is Down or Not Responding

This error can occur if you are running DHCP (to obtain a dynamically assigned IP address) on your license server. MATLAB cannot connect with the License Manager because it uses TCP/IP protocols for communication and your IP address is changing.

To fix this problem, follow this procedure.

Obtain the current IP address for your server. If you are on UNIX or Linux, use the ifconfig command. On a PC running Windows, you can use the ipconfig command at a DOS prompt.
Edit your hosts file and change the IP address for your server’s entry to be the correct IP address. On UNIX or Linux systems, edit the /etc/hosts file. On Windows NT and Windows 2000 systems, edit the C:Winntsystem32driversetchosts file.

License Manager Error -97: License Checkout Failed

This error is often caused by trying to run both MATLAB 5.3 and MATLAB 6.5 on the same system with different license managers. If this is the case, run both copies of MATLAB with the same License File. See Performing Common License Management Tasks for more information.

If you are not trying to run MATLAB 5.3 but only want to run MATLAB 6.5, make sure you have installed FLEXlm version 8.0d from the Release 13 CD. MATLAB 6.5 will not run with an older version of the license manager.
