4 System Configuration: Servers, Data Sources, and Agents Copyright © 2010, Oracle and/or its affiliates All rights reserved Objectives After completing this lesson, you should be able to: • Manage servers by using the OAM administration (admin) console and the Oracle WebLogic Server (WLS) admin console • Manage data sources – User Identity Store • Register and manage agents by using the OAM admin console • Register agents remotely • Secure communication between a WebGate and the OAM server 4-2 Copyright © 2010, Oracle and/or its affiliates All rights reserved Practice Overview: Installing and Configuring OHS 11g This practice covers the following topics: • 4-3 Practice 4-1: Install and configure OHS 11g instances Copyright © 2010, Oracle and/or its affiliates All rights reserved Road Map • • • • • • 4-4 Managing OAM servers Installing and configuring agents Registering agents: The OAM admin console, in-band, out-of-band Understanding WLS agents Managing data sources Securing communication between agents and the OAM server Copyright © 2010, Oracle and/or its affiliates All rights reserved Servers Oracle Access Manager servers are of two types: • OAM administration server • OAM managed server – Contains embedded the OAM and OSSO proxy server to support backward compatibility OAM servers are initially created by using: • The WLS Configuration Wizard OAM servers are managed by using: • • • • 4-5 The OAM admin console (primary management interface) The WLST command-line interface The WLS admin console: status, start/stop The EM FMW Control: view logs, start/stop, monitoring, operational metrics Copyright © 2010, Oracle and/or its affiliates All rights reserved Creating and Deleting a New Managed Server 4-7 Copyright © 2010, Oracle and/or its affiliates All rights reserved Managing Servers • The OAM admin server is also know as WLS admin server AdminServer (admin) – The OAM admin console and EM FMW Control run within the admin server • The OAM run-time server runs within the OAM managed server oam_server1 (default name) • By using the WLS Configuration Wizard or WLS admin console or WLST CLI you can: – Create new managed servers (for clustering – high availability) – Change the default name and port for managed servers • By using the OAM admin console or WLST CLI you can: – Create the definition for new managed servers – Set the individual and common server properties 4-8 Copyright © 2010, Oracle and/or its affiliates All rights reserved Individual Server Properties • OAM admin console > System Configuration tab > Server Instances > server_name • Server Properties: – Site Name: This is a name for the server instance, defined during initial configuration by using the Configuration Wizard – Host: This is the full DNS name (or IP address) of the computer that is hosting the server instance – Port: This is the port on which this server communicates – OAM Proxy: — WebLogic Port: WLS listening port — Port: OAM proxy instance port — Proxy Server ID: Identifier of the computer on which the OAM proxy resides — Mode: Transport security setting for the OAM proxy – Coherence 4-9 Copyright © 2010, Oracle and/or its affiliates All rights reserved OAM Proxy • Motivation for OAM proxy: – OAM proxy is installed with each managed server for the OAM server and is used for communication between WebGates and the OAM 11g server – It is used as a legacy access server to provide backward compatibility for OAM 10g agents that are registered with the OAM 11g server – It coexists with 10g WebGates/ASDK – It supports OAM 11g WebGates • Functionality: – It shields the 11g server from client-specific behavior and protocol – It supports the OAP (formerly known as NAP) back channel for WebGates to the 11g server The default port is 5575 – It supports HTTP front channel request handling required for WebGates - 11 Copyright © 2010, Oracle and/or its affiliates All rights reserved Managing Servers from WLS Admin Console and Command Line • WLS Admin Console > > Environment > Servers • Common Operations: – Start/Stop screenshots – Show Deployments tab – Show both admin and managed server for OAM • Command line option to start: – Admin server: startWeblogic.cmd – Managed server: startManagedWebLogic.cmd server_name http://admin_server_host:admin_server_port -
