This chapter introduces you to the general tasks involved in administering and managing Oracle Communications Evolved Communications Application Server (OCECAS).
For tasks specific to configuring OCECAS, see "Configuring Evolved Communications Application Server".
In your daily administration of OCECAS, you perform various tasks associated with WebLogic and other systems. The tasks include managing the following:
Servers and Domains. See "About Managing the Servers and Domains".
Sessions. See "About Managing Sessions".
Connections. See "About Managing Connectivity".
Resources. See "About Managing the System Resources".
See "Configuring Evolved Communications Application Server" for information about configuration tasks specific to OCECAS.
System administrators create domains, migrate a domain from one environment to another, and track changes in the domains.
For more information about managing servers and domains, see "Creating and Configuring OCECAS Domains" in Evolved Communications Application Server Installation Guide.
Based on your installation, you use one of the following to manage sessions:
Core Session Manager. See "About Managing Core Session Manager Elements".
Session Border Controller. See "About Managing Session Border Controller".
Unified Session Manager. See "About Managing Unified Session Manager Elements".
Oracle Communications Core Session Manager, when integrated into your environment, provides the following functions and roles:
Session call session control function (S-CSCF).
Interrogating call session control function (I-CSCF).
Information about the Core Session Manager elements is available in the Oracle Communications Core Session Manager documentation set at Oracle Help Center:
Oracle Communications Session Border Controller, when integrated into your environment, provides the following functions and roles:
Breakout Gateway control function (BGCF).
Emergency call session control function (E-CSCF).
IMS Access gateway (IMS-AGW).
Interconnect Border control function (IBCF).
Interrogating and Session call session control function (I/S-CSCF).
Media Gateway control function (MGCF).
Proxy call session control function (P-CSCF).
Information about Session Border Controller is available in the Oracle Communications Session Border Controller documentation at Oracle Help Center:
Oracle Communications Unified Session Manager, when integrated into your environment, provides the following functions and roles:
Access Transfer Gateway (ATGW).
Access Transfer control function (ATCF).
Emergency call session control function (E-CSCF)
IMS Access gateway (IMS-AGW).
Interrogating call session control function (I-CSCF).
Proxy call session control function (P-CSCF).
Information about Unified Session Manager elements is available in the Oracle Communications Unified Session Manager documentation set at Oracle Help Center:
As part of daily maintenance of network connectivity, you maintain the connections to the following elements:
Web servers
For information about WebLogic servers, see the Oracle WebLogic Server 12c Release documentation set at Oracle Help Center.
Databases
For information about the managing the Oracle database, see the Oracle database 12c Release documentation set at Oracle Help Center.
Internal data sources
For information about the managing connectivity with data sources, see the appropriate documentation set at Oracle Help Center:
In OCECAS, a resource can be a web service, a server instance, or the Session Design Center application. It can also be an activity that takes place in your system. For example, RESTful web service API methods that allow applications and individuals access to a specific URI form an activity.
To manage OCECAS resources, you manage the following:
Session Design Center. See "About Managing the Session Design Center".
Templates. See "Managing the Templates".
Databases. See "Managing Databases".
You manage connections to one or more of the following databases:
Oracle database. See "Topics for Administrators and Developers" at Oracle Help Center.
User database repository (UDR) databases such as NoSQL, Home Subscriber Server (HSS). See the documentation for the database appropriate to your installed environment.
