Prior to SBC 9.0, the SBC Manager of the EMS is dependent on the REST services provided by the EMA. If the EMA is disabled, you cannot configure the SBC from the EMS using the SBC Manager.
To overcome this problem, the EMA is segregated into three major components:
Independent EMA Components
EMA Component | Function |
---|---|
Core | All of the existing EMA GUI options and functions, except Live Monitor and CDR Viewer options. |
Troubleshooting | Live Monitoring, CDR Viewer, and the "All" perspective in the SBC main screen. |
REST | Provides REST APIs to support SBC Manager in the EMS. When the REST component is disabled, you cannot configure the SBC from the EMS, using the SBC Manager. |
If you upgrade the EMA from a pre-9.0 version to 9.0 or higher, all the components are enabled. However, if you upgrade the EMA from 9.0 to higher versions, the state of the components in the upgraded version remains the same as that of the old version.
When you disable the EMA Core/Management and enable the Troubleshooting component, the following restrictions apply to Sign In screens and other user interfaces:
To disable/enable EMA components from the CLI, the following enhancements are available:
ema
is added under system admin
. The child parameters of ema
, each with the disable/enable options, are as follows:enableCoreEMA
enableREST
enableTS
ema
, with its child parameters, are available under system admin
of the show
commands.To disable/enable the EMA components, use the following syntax:
% set system admin <system_name> ema enableCoreEMA <disabled | enabled> enableREST <disabled | enabled> enableTS <disabled | enabled>
To display the status of the EMA components, use the following syntax:
Within the "configure" mode:
% show system admin <system_name> ema <enableCoreEMA | enableREST | enableTS>
Outside of the "configure" mode:
> show table system admin <system_name> ema <enableCoreEMA | enableREST | enableTS>
If you do not provide the name of the EMA component, the output displays the status of all the three components.
Parameter Description Table
Parameter | Length/Range | Default | Description | M/O |
---|---|---|---|---|
ema | N/A | N/A | The object encapsulating the three EMA components. | O |
enableCoreEMA | N/A | enabled | Use this parameter to disable or enable the Core EMA component.
| O |
enableREST | N/A | enabled | Use this parameter to disable or enable the REST API services provided by the EMA for SBC configuration (using the SBC Manager of the EMS).
| O |
enableTS | N/A | enabled | Use this parameter to disable or enable the Troubleshooting component of the EMA.
| O |
The SBC is enhanced to enable/disable these components independently; the state of one component does not affect the function of the other components. For using the full capabilities of the EMA, Ribbon recommends enabling all the components simultaneously.
You can disable/enable the components during installation, or after the installation. By default, all the components are enabled. For the post-installation changes to take effect, restart the application.
To configure the EMA components, use the following example:
% set system admin REDGRAPE-SA ema enableCoreEMA enabled enableREST disabled enableTS enabled
To display the status of the EMA components, use the following example:
Within "configure" mode:
% show system admin REDGRAPE-SA ema enableREST enabled; enableCoreEMA enabled; enableTS enabled; [ok][<YYYY-MM-DD HH:MM:SS>]
Outside "configure" mode:
> show table system admin REDGRAPE-SA ema enableREST enabled; enableCoreEMA enabled; enableTS enabled; [ok][<YYYY-MM-DD HH:MM:SS>]
