Manually Configuring Licensing for Abaqus

When you installed either the FLEXnet or Dassault Systèmes license server, you may have chosen to skip the installer's automatic setup of client application licensing. If so, follow the instructions below to manually configure an Abaqus installation for either license server.

This task shows you how to:

Before you begin: You must finish installing the files for the FLEXnet licensing or DS License Server before performing this configuration.

Configure Abaqus for a FLEXnet License Server

  1. Edit the following environment customization file in the Abaqus installation: 

    install_dir/os/SMA/site/custom_v6.env

  2. In the custom_v6.env file, add the following parameters: 

    license_server_type=FLEXNET
abaquslm_license_file="port@license_server_hostname"

Configure Abaqus for a DS License Server

  1. On Windows, create the following directory:
    C:\ProgramData\DassaultSystemes\Licenses

    On Linux, create the following directory:

    /var/DassaultSystemes/Licenses
  2. Go to the directory and create an ANSI text file (multi-bytes such as UNICODE are not supported) named:

    DSLicSrv.txt

  3. Edit the file to declare the DS License Server to which the Abaqus client can connect.

    The syntax of the declaration is as follows: 

    servername:port

    The server name can be declared as:

    • a simple hostname, for example: lw5ses1dsy:4085
    • a full qualified domain name, for example: lw5ses1dsy.dsy.com:4085
    • an IPV4 address, for example: 10.232.70.1:4085
    • an IPV6 address, for example: [2a00:4b00:220:172::103]:4085

    The port number is the license server listening port, not the administration port.

    Note: If the DS License Server is on the same computer as Abaqus, you must use the special keyword localhost instead of the computer name, for example: 
    localhost:4085
    Note: The syntax for failover servers is different. The three failover servers must all be referenced on the same line as follows: 

    server1:4085,server2:4085,server3:4085

    By default, load balancing of the three failover members is performed automatically by the licensing client (Abaqus). At startup, Abaqus selects randomly the failover member to contact from the three members declared. If the first selected member is down, the second member is randomly selected, and so forth. This ensures that the three members are statistically contacted by the same number of clients and results in automatic load balancing on the three members.

    However, it is also possible to specify the order of priority in which failover members are contacted by Abaqus, replacing randomization by an explicit order defined by the administrator. This can be useful in the following cases, for example if:

    • one member is more (or less) powerful than the others
    • one member is located much closer to (or further from) the licensing clients than the others
    • one member cannot be reached due to proxy constraints
    • one member is temporarily down.

    Note: You cannot mix automatic and manual configurations; in other words, the three failover members are either randomly accessed or are accessed through the specified order. So you cannot, for example, declare the first member then set random access to the remaining two members.

    To explicitly specify an order of priority order between the failover members, use the following separator: 

    >

    instead of: 

    ,

    which is reserved for automatic load balancing.

    The following declaration is valid, for example: 

    licmbr1:4085>licmbr2:4085>licmbr3:4085

  4. If several logical (i.e. standalone or failover) Dassault Systèmes License Servers need to be accessed, add a new line for each logical license server.

    In this context, when Abaqus requests a license and this license is not already granted by one of the declared logical servers, then the order in which the logical license servers is declared is observed. If a license is available on the first declared logical server, this one is taken; if not, if a license is available on the second declared logical server, then this one is taken, and so forth.

  5. Optional: Check that the DSLicSrv.txt file is correctly configured.

    The license client-side DSCheckLS command parses the DSLicSrv.txt file to check license server availability, and reports errors if, for example, the file is incorrectly configured.

  6. Edit the following environment customization file in the Abaqus installation: 

    install_dir/os/SMA/site/custom_v6.env

  7. In the custom_v6.env file, add the following parameters: 

    license_server_type=DSLS
dsls_license_config="C:\\ProgramData\\DassaultSystemes\\Licenses\\DSLicSrv.txt
