CMS operates in three license modes:

• License Normal

• License Error

• License Restricted

The logs record transitions between these modes and generate alarms when entering the License Error or License Restricted mode.

License Normal mode

The License Normal mode indicates that there are no license violations. In this mode:

• The CMS instance connects to WebLM.

• The CMS instance shares the latest license information.

License Error mode

The License Error mode indicates a license violation. In this mode, CMS performs the following actions:

• Issues a warning message when an administrative user logs in or when the user invokes cmssvc or cmsadm.

• Issues a daily alarm.

If the CMS instance remains in the License Error mode for more than 30 days, CMS performs one of the following actions:

• Attempts to resolve the violations.

• Transitions to the License Restricted mode, depending on the nature of the violations.

When the CMS instance clears all license violations for eight consecutive days, CMS returns to the License Normal mode.

License Restricted Mode

When CMS enters the License Restricted mode, the CMS instance enforces the following restrictions:

• Closes and blocks all user interface sessions.

• Enables limited access through the ASCII interface:

  • The cms user can access only the System Setup and Maintenance submenus.

  • The cmssvc user can access the Services submenu in addition to System Setup and Maintenance.

• Closes all external and internal CLInt sessions and prevents new CLInt sessions from starting.

• Closes all JDBC and ODBC sessions and blocks new sessions.

• Stops External Call History.

After the CMS instance clears all license violations, CMS returns to the License Normal mode.
