Licensing of the eG Manager

In the eG Enterprise architecture, the license is centrally controlled on the eG manager. The license on the eG manager is typically node-locked. That is, if you need to move the manager to a different IP address or host, you will need to get a new license for the manager. The details of the license deployed on an eG manager can be viewed from the license information page of the eG administration console (see Figure 1).

For the eG manager to function, the license must support the IP address and MAC of the system on which the eG manager is installed. The version of the eG license should also match the version of the eG manager that is it deployed on. For example, a version 6.1 license should not be used to operate an eG manager v 6.2.1.

If the eG manager fails to start, please check the error_log file in the <EG_INSTALL_DIR>\manager\logs folder.  An error “LicenseMgr – Invalid License” indicates that the license you have deployed on the eG manager is not valid.

If the eG manager does not start, you will not be able to view the license details from the eG administration interface. In such cases, a command line utility “viewCert” is included in the eG manager package to view the license details. To run this command, do the following (on Windows, Linux or Solaris):

  1. Login to the eG manager host.
  2. On a Solaris/Linux host, switch to the /opt/egurkha/bin directory (in case of a Windows host, switch to the <EG_INSTALL_DIR>\bin directory).
  3. To view the license, issue the following command on a Solaris/Linux/Windows: viewCert license
