Overview
Prior to SBC 9.0, the EMS SBC Manager depends on the REST API 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:

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:

Configuration Examples
Tip | ||
---|---|---|
| ||
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:
Code Block |
---|
% 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:
Code Block % show system admin REDGRAPE-SA ema enableREST enabled; enableCoreEMA enabled; enableTS enabled; [ok][<YYYY-MM-DD HH:MM:SS>]
Outside "configure" mode:
Code Block > show table system admin REDGRAPE-SA ema enableREST enabled; enableCoreEMA enabled; enableTS enabled; [ok][<YYYY-MM-DD HH:MM:SS>]
