Learn about tasks necessary for license server administration and information about license server tools and functions.

• Understanding the SySAM Directory Structure
  SySAM files are installed in the SYSAM-2_0 directory.
• Installing the SySAM License Server
  Learn how to install the license server.
• Starting and Stopping License Servers
  When you start or stop license servers, keep these requirements in mind.
• Determining License Server Version and Status
  You can determine license server version and status by using the sysam status command. You can determine the versions of lmgrd and SYBASE vendor daemon by using the -v option.
• Monitoring License Use
  To determine the status of a specific license server, establish which licenses are available, and where licenses are currently being used, use the sysam status command.
• Registering New and Updated License Files
  To update multiple licenses at once, use Manage License Hosts at SPDC or SMP.
• Managing the License Server Debug Log
  By default, all license server status and error messages are written to the debug log file SYBASE.log in the log directory.
• Controlling License Use with the SySAM Options File
  The options file (SYBASE.opt, in the licenses directory) allows license administrators to control various licensing operating parameters and to designate users of specific licenses.
• SySAM Utilities
  The licensing utility program, lmutil, includes the options for managing licensing activities.
• Configuring SySAM for Redundancy
  Configure SySAM for redundancy by setting up a three-server redundant cluster or by specifying multiple license servers.
• Access Through a Firewall or VPN
  SySAM license server listens on two TCP/IP ports for incoming license requests. Therefore, any firewall or VPN policies must be set up to allow access to both ports.
