# Managing Oracle Communications Services Gatekeeper: OAM

This chapter describes Operation, Administration, and Maintenance (OAM) functionality for Oracle Communications Services Gatekeeper.

- Overview
- The WebLogic and Oracle Communications Services Gatekeeper Management Console
- OAM Tasks Overview
- OSS Integration

## Overview

Oracle Communications Services Gatekeeper is usually controlled through the Oracle Communications Services Gatekeeper Management Console, a specialized extension of the general WebLogic Server Administration Console. The console is a Web-based tool and can be run in any environment that supports appropriate Web browsers. For general information on the administration console, see Introduction to Oracle WebLogic Server at http://download.oracle.com/docs/cd/E12840_01/wls/docs103/intro/.

For some tasks, you can also use scripts that run in the WebLogic Scripting Tool: see Oracle Weblogic Server WebLogic Scripting Tool at http://download.oracle.com/docs/cd/E12840_01/wls/docs103/config_scripting/.

In addition, all or selected parts of the management application can be integrated with external Operation Support Systems (OSS) using JMX/JMS and alarms can be distributed using SNMP traps.

Finally, the application service provider management tool functionality can be integrated with PRM and CRM systems using the Oracle Communications Services Gatekeeper Partner Relationship Management Interfaces.

Administrative users can be divided into user groups with access to different aspects of the administrative functionality. Within user groups, individual users can have differing levels of access. See System Administrator’s Guide for more information.

## The WebLogic and Oracle Communications Services Gatekeeper Management Console

The Oracle Communications Services Gatekeeper Management Console is a Web browser-based, graphical user interface that you use to manage an Oracle WebLogic Server domain. A standard production installation for Oracle Communications Services Gatekeeper consists of at least one WebLogic Server domain.

One instance of WebLogic Server in each domain is configured as an Administration Server. The Administration Server provides a central point for managing an Oracle Communications Services Gatekeeper domain. All other server instances in the domain are called Managed Servers. In Oracle Communications Services Gatekeeper, they are divided into Access Tiers and Network Tiers. In a domain that contains only a single WebLogic Server instance, such as a development environment, that server functions as the Administration Server and both Managed Servers, that is, the Access Tier and the Network Tier. The Administration Server hosts the Administration Console, which is a Web application accessible from any supported Web browser with network access to the Administration Server. To access the console, use the following URL:

    http://<hostname>:<port>/console

where `hostname` is the DNS name or IP address of the Administration Server and `port` is the port on which the Administration Server listens for requests.

## OAM Tasks Overview

Use the Administration Console to:

- Configure, start, and stop Oracle Communications Services Gatekeeper instances
- Configure Oracle Communications Services Gatekeeper clusters
- Configure Oracle Communications Services Gatekeeper services, such as database connectivity (JDBC) and messaging (JMS)
- Monitor server and application performance
- View server and domain log files
- View application deployment descriptors
- Edit selected run-time application deployment descriptor elements
- Upgrade communication services
- Configure security parameters and roles

Use the Oracle Communications Services Gatekeeper-specific section (accessed through the Domain Structure tree on the left side of the Administration Console) to:

- Configure Oracle Communications Services Gatekeeper communication services
- Manage administrative users and groups
- Provision Application Service Providers, Applications, Application Instances, and related SLAs.
- Monitor alarms, CDRs, and EDRs
- Create multiple plug-in instances, set up plug-in routing, etc.

Tasks performed outside the Console

- Extend Oracle Communications Services Gatekeeper’s functionality
- Back up and restore the system
- Upgrade the system

Complete information about Oracle Communications Services Gatekeeper OAM can be found in the System Administrator’s Guide, another document in this set.

## OSS Integration

- All or selected parts of the management application can also be integrated with external Operation Support Systems (OSS) through secured JMX/JMS interfaces. For more information on working with JMX, see Oracle WebLogic Server Developing Manageable Applications with JMX at http://download.oracle.com/docs/cd/E12840_01/wls/docs103/jmxinst/ and Oracle WebLogic Server Configuring and Using the WebLogic Diagnostics Framework at http://download.oracle.com/docs/cd/E12840_01/wls/docs103/wldf_configuring/. Alarm supervision systems can set up external JMS listeners to receive user definable types of event-based data, including standard alarms. SNMP traps are sent to any registered SNMP managers.
