Licensing Overview

When you add an AutoClient to a server using Host Manager, a license, if one is available, is automatically checked out by the server. Solstice AutoClient 2.1 uses the latest Globetrotter FLEXlm^TM licensing packages to make licensing as easy as possible.

Solstice AutoClient 2.1 licensing does not deny service. An AutoClient can function without licensing.

Solstice AutoClient 2.1 License Components

Solstice AutoClient 2.1 product licensing entails the following system components.

• AutoClient server (OS server)

  A license request is generated by the AutoClient server in the following cases:

  • When an AutoClient is added to the AutoClient server

  • When the AutoClient server is booted

  The AutoClient server requests a license for each AutoClient it is configured to support. It obtains this information from the bootparams database.

• License server

  The license server receives the request to provide a license for an AutoClient from the AutoClient server, and it grants or denies this request.

Figure 4-1 describes the events that cause the AutoClient server to request a license.

Figure 4-1 The Solstice AutoClient 2.1 License Process

If the AutoClient server is not configured to contact the license server and request a license, a message similar to the following is displayed.

Dec 22 13:34:53 server-name License Error : Cannot find license file
(/usr/local/flexlm/licenses/license.dat)
Dec 22 13:34:53 server-name which contains the feature 
solstice.autoclient.
Dec 22 13:34:53 server-name Cannot find license file (-1,73:2) No such file or directory
Dec 22 13:34:53 server-name ac_licensed[194]: [uid=0]
Dec 22 13:34:53 server-name The product has not been installed 
properly.
Dec 22 13:34:54 server-name Cannot find license file (-1,73:2) No such file or directory
Dec 22 13:34:53 server-name ac_licensed[194]: [uid=0]  There are no 
license files in following path :
Dec 22 13:34:54 server-name /opt/SUNWadm/license_dir/sunpro.lic,1
Dec 22 13:34:54 server-name Cannot find license file (-1,73:2) No such file or directory
Dec 22 13:34:53 server-name ac_licensed[194]: [uid=0] license refused 
for client-name

This message is also written to the message file stored in the /var/adm directory on the AutoClient server.

Since the Solstice AutoClient 2.1 product does not deny service if a license is unavailable, the functionality provided by the AutoClient server to the AutoClients it supports is unaffected.

AutoClient Server License Configuration

Host Manager automatically installs the AutoClient server with the supporting software required by the license process described in Figure 4-1. This occurs when an AutoClient is first added to the server.

Licensing is managed on the AutoClient server by the following software components.

• License Daemon - ac_licensed

  This is the Solstice AutoClient 2.1 license daemon. It is located in the /usr/opt/SUNWadm directory, and it is started automatically at boot time by the S86ac_licensed script, or it can be started by Host Manager when an AutoClient is first added to the server.

• License Script - S86ac_licensed

  This is the Solstice AutoClient 2.1 license daemon startup script. It is located in the /etc/rc2.d directory. It runs automatically when the AutoClient server is rebooted, and it can also be executed manually with the start or stop option to manage the Solstice AutoClient 2.1 license daemon.

• License File - sunpro.lic,1

  This is the Solstice AutoClient 2.1 license file (also known as the elementary license file) used to store information about the license server. It is created during the license server installation process described in Table 4-1, and it is stored on the station manager system that is installed with the Solstice AutoClient 2.1 software.

  When the Solstice AutoClient 2.1 license daemon startup script runs, it looks for this file in the /opt/SUNWadm/license_dir directory. The first time the file is found, the script creates a local copy in the /usr/opt/SUNWadm directory and reads the license information stored in the file.

  If the license file subsequently becomes unavailable in the /opt/SUNWadm/license_dir directory, the license daemon startup script attempts to read the local copy in the /usr/opt/SUNWadm directory.

  If the license file is unavailable in either directory, an error message is displayed.

If you remove or unmount the /opt/SUNWadm/license_dir directory, the Solstice AutoClient 2.1 license file will be unavailable. Verify that a backup copy of this file (sunpro.lic,1 ) is located in the /usr/opt/SUNWadm directory. Otherwise, AutoClient server license requests will fail.

License Server Configuration

Table 4-1 shows tasks you perform to set up the license server.

How to Select the License Server(s)

If you are installing the product and the license on the same server, you can skip this section, and go to "How to Gather Information for Your License".

Before you can get the license passwords for your Solstice AutoClient 2.1 product, you must select the machines you will use as a license servers. Select the most stable machines to serve as license servers. Do not select a machine that is frequently shut down and rebooted.

With the FLEXlm license management software, you can use any of the following types of server configurations:

• Single independent server - All product licenses are handled by a single server.

• Multiple independent servers - Each server acts separately to administer a subset of the product licenses.

• Three redundant license servers - A collection of servers, effectively acting as one server, jointly administering a set of product licenses.

  The default is a single server. This is the easiest to install and the most widely used configuration. Your license servers can administer licenses for multiple products.

How to Gather Information for Your License

Before you contact the License Distribution Center to get your password, gather the following information:

1. Locate the serial number on your Solstice AutoClient 2.1 license certificate.

   A sample serial number is listed in the licensing information below.

   Product Name: Solstice AutoClient Version: 2.1 Rights to Use: 10 Serial Number: 1213 6212 2013 0418

2. To display the SunOS release number, host information, and additional information you need when you get your license, type:

   % showrev

   Your screen shows information similar to the following:

   Hostname: notalone Hostid: 530110ab Release: 5.5 Kernel architecture: i86pc Application architecture: i386 Hardware provider: Sun_Microsystems Domain: XYZ.DIV.Company.COM Kernel version: SunOS 5.5 Generic. May 1995
