A graphical control panel that displays server status information and enables you to perform basic server and data administration. For information about deploying the replication gateway in a migration scenario, see Section 26.11, "Replicating Between Oracle Directory Server Enterprise Edition and Oracle Unified Directory". ", For more information about which Oracle Unified Directory server mode you should use, see Section 1.1.2, "Oracle Unified Directory Installation Types.". The replication gateway translates and propagates replication information effectively between directory servers from Oracle Directory Server Enterprise Edition and directory servers from Oracle Unified Directory. This network group is also associated to Workflow 1, with naming context dc=example,dc=com. The proxy workflow element provides direct access to the remote data source. For a proxy server, the workflow elements can be chained with load balancing workflow elements or distribution workflow elements that act as a pointer, routing the request along a specific path. If it does not match all of the criteria, it forwards the request to the next network group in the list: Network Group 2. QoS policy set with resource limits size limit=0, time limit=0. The operation is routed to a network group based on the network group criteria assigned. Virtual workflow element: This type comprises the DN renaming workflow elements, RDN changing workflow elements, and Transformation workflow elements. This section presents the high-level architecture of Oracle Unified Directory. You can obtain Oracle Directory Integration Platform by installing Oracle Identity Management release 11.1.1.6.0 or above. Oracle Unified Directory supports several different types of workflow elements: Leaf workflow elements: This type comprises the Local Backend workflow elements and proxy workflow elements. A search with bind DN **,dc=example,dc=com would be handled by Network Group 3 and sent to Workflow 1 and Workflow 2. For high availability, two replication gateway servers are deployed in every transition scenario. Section 1.2, "Overview of Directory Server. For more information about how to enable the changelog in Oracle Unified Directory, see Section 32.7, "Using the External Change Log.". Figure 5-3 High-Level Presentation of Oracle Unified Directory Components. For more information about security, see Chapter 21, "Configuring Security Between the Proxy and the Data Source. The proxy server does not contain any data. The administration connector enables the separation of user traffic and administration traffic to simplify logging and monitoring, and to ensure that administrative commands take precedence over commands that manipulate user data. Several command-line utilities to assist with configuration, administration tasks, basic monitoring, and data management. For example, if the bind DN was uid=user.1,dc=test,dc=com, the request would not be accepted by Network Group 1, but would be forwarded to and accepted by Network Group 2, and forwarded to Workflow 2. After the request has gone through the assigned processing, the request is sent to the data source. An operation must comply with the network group QoS policies regardless of the server profile, directory server or proxy server. This section provides a brief overview of the proxy component of Oracle Unified Directory. You can use the proxy to authorize or restrict access to remote directory servers. The Oracle Unified Directory server is an LDAPv3 compliant directory server written entirely in Java. The best way to handle incompatible features (for example, macro ACIs, CoS, password policies) is to filter out the affected object classes and attribute types before replication occurs. oam 11g All client requests are routed by the proxy to the appropriate remote LDAP server.

The workflow forwards the operation to its tree of workflow elements, which defines how to treat the request. Example 4-1 Using Network Group Criteria to Route to Different Workflows. This access control group contains all ACIs coming from user data. Figure 4-3 High-Level Presentation of Oracle Unified Directory Components, Description of "Figure 4-1 Network Group Selection", Section 13.1.6, "Configuring Network Groups With, Description of "Figure 4-2 Client Request for a Directory Server", Description of "Figure 4-3 High-Level Presentation of Oracle Unified Directory Components". The proxy is the entry point to a directory service deployment spread over multiple directory servers, multiple data centers, or both. This section presents the high-level architecture of Oracle Unified Directory. The proxy workflow element provides direct access to the remote data source. You can disable changes from being propagated from the Oracle Unified Directory servers to the Oracle Directory Server Enterprise Edition replication topology, according to your transition scenario. Each workflow is associated with an access control group, which defines the list of ACIs that apply to operations handled by this workflow. You can obtain Oracle Directory Integration Platform by installing Oracle Identity Management release 11.1.1.6.0 or above. Some simple deployments are detailed in Chapter 3, "Example Deployments Using the Proxy Server.". The suffix for w1 is ou=X and a workflow points to a tree of workflow elements. A network group can point to several workflows if the naming contexts of the workflows are different. Assume an Oracle Unified Directory configuration with the following network groups: Network Group 1: criteria set with bind DN **,dc=example,dc=com, This network group is associated with Workflow 1, with naming context dc=example,dc=com, Network Group 2: criteria set with bind DN **,dc=test,dc=com, This network group is associated with Workflow 2, with naming context dc=test,dc=com. If you want to use Directory Integration Platform to enable synchronization for Oracle Unified Directory, you need to enable the Oracle Unified Directory changelog. For a proxy server, the workflow elements can be chained with load balancing workflow elements or distribution workflow elements that act as a pointer, routing the request along a specific path. However, an incoming client connection can only be attached to one network group at a time. ", Section 1.4, "Overview of the Replication Gateway. By including the proxy in your deployment, you ease the configuration and management of client applications. For detailed information about some simple deployments, see Chapter 3, "Example Deployments Using the Proxy Server. ", Chapter 21, "Configuring Security Between the Proxy and the Data Source. Oracle Directory Server Enterprise Edition was formerly known as the Sun Java System Directory Server. Replication is the mechanism that propagates a change made on one directory server to multiple different directories in a replication topology. Feature translation. You could resolve this issue by replacing the single server with several servers, and splitting the data across these servers. ", Example 5-3 A Network Group Routing to Several Workflows. Within the overall replication topology, the replication gateway acts as a two-way forwarding server. Directory Integration Platform synchronization can be described as follows: Section 1.1.3.1, "Synchronization between Oracle Unified Directory and Oracle Internet Directory", Section 1.1.3.2, "Synchronization between Oracle Unified Directory and Third-Party Directories". Instead, the client application sends a request to the proxy.

This section provides a brief overview of the directory server component of Oracle Unified Directory server. Network Group 1 assesses if the request matches all the required criteria. The proxy also provides a single access point for managing security in a directory service. ", Section 32.7, "Using the External Change Log.

", Section 1.4, "Overview of the Replication Gateway. Oracle Unified Directory is a comprehensive next generation directory service. It propagates modifications from the Oracle Directory Server Enterprise Edition servers to the Oracle Unified Directory replication topology, and from the Oracle Unified Directory servers to the Oracle Directory Server Enterprise Edition replication topology. The replication gateway does not manage the following aspects: Data initialization. This chapter covers the following topics: Section 4.1, "Oracle Unified Directory Components", Section 4.2, "Architecture of Oracle Unified Directory". ", Section 1.4.2, "The Role of the Replication Gateway", Section 1.4.3, "Limitations of the Replication Gateway". It is designed to address large deployments and to provide high performance, and is highly extensive. Each workflow contains at least one workflow element. You can use the proxy to authorize or restrict access to remote directory servers.

Each workflow contains at least one workflow element. This section provides an overview of each component and contains the following topics: Network groups are the entry point of all client requests handled by Oracle Unified Directory. Scripting on this page enhances content navigation, but does not change the content in any way. The client connection is assessed by each network group, in order of priority, until it complies with all the criteria of that network group. A workflow is defined by a naming context (base DN) and a workflow element that define how Oracle Unified Directory should handle an incoming request. Enhanced multi-master replication across directory server instances, Assured replication feature that ensures high availability of data and immediacy of data availability for specific deployment requirements, Support for an external change log that publicizes all changes that occur in a directory server database, Support for various levels of authentication and confidentiality. ", Section 1.2, "Overview of Directory Server", Section 1.4, "Overview of the Replication Gateway". After the request has gone through the assigned processing, the request is sent to the data source. Section 1.2, "Overview of Directory Server. For more information about workflows, see Section 4.1.2, "Workflows". You can disable changes from being propagated from the Oracle Unified Directory servers to the Oracle Directory Server Enterprise Edition replication topology, according to your transition scenario. Once configured, the proxy automatically distributes client queries to different directory servers conforming to the load criteria defined in the configuration. Oracle Directory Integration Platform consists of a set of services and interfaces that facilitates synchronization and provisioning solutions between the directory and other repositories. ", For an in-depth presentation of the elements that constitute the Oracle Unified Directory proxy, see Chapter 11, "Understanding the Proxy Functionality.". If the request matches all the properties of a network group, the network group assesses if the client connection matches the QoS policies of that network group. This option enables you to filter out object classes and attribute types that do not apply to Oracle Unified Directory servers. Schema coherency. This chapter provides an overview of Oracle Unified Directory and explains some of the unique features of Oracle Unified Directory. Assume an Oracle Unified Directory configuration with the following network groups: Network Group 1: criteria set with bind DN **,dc=example,dc=com, This network group is associated with Workflow 1, with naming context dc=example,dc=com, Network Group 2: criteria set with bind DN **,dc=test,dc=com, This network group is associated with Workflow 2, with naming context dc=test,dc=com. The proxy is the entry point to a directory service deployment spread over multiple directory servers and/or multiple data centers. The replication gateway does not manage the following aspects: Data initialization.

By default, an access control group known as Local Backends, exists. For more information about setting up the proxy server, see Setting Up the Proxy Server chapter in Oracle Fusion Middleware Installation Guide for Oracle Unified Directory. Translations are managed "on the fly" without storing any data on disk. Oracle Directory Integration Platform 11.1.1.5 and higher supports synchronization between Oracle Internet Directory and Oracle Unified Directory. This chapter provides conceptual descriptions of the basic components of Oracle Unified Directory and discusses Oracle Unified Directory architecture.

These capabilities enable you to meet the evolving needs of an enterprise architecture. Virtual workflow element: This comprises the DN renaming workflow elements. Network groups handle all client interactions and dispatch them to local back end workflows or proxy workflows, based on: Criteria can include security authentication level, port number, client IP mask, client bind DN, bind ID, domain name, and other criteria. If you want the server to act as an interface between the client and the directory server containing the data, then install Oracle Unified Directory as a proxy server. To enable synchronization of data between Oracle Unified Directory and third-party directories, you must integrate Oracle Directory Integration Platform with Oracle Unified Directory. EUS workflow element: This type comprises the Enterprise User Security (EUS) workflow elements. ", Section 1.1.2, "Oracle Unified Directory Installation Types. Network Group 2: criteria set with bind DN **,dc=example,dc=com. topology monitoring oracle replication replicated obtain command status run following directory docs cd figure The replication gateway translates the synchronization mechanism specific to each version of the directory, offering two-way replication between the disparate topologies. Oracle Unified Directory components include: LDAP directory server, used for storing data, For more information about directory server, see Section 1.2, "Overview of Directory Server.

EUS workflow element: This comprises the Enterprise User Security (EUS) workflow elements. Oracle Unified Directory integrates three key components: Network Groups, Workflows, and Workflow Elements. To create an LDAP directory server that contains directory data, install Oracle Unified Directory as a directory server. The determination of the workflow is based on the match between the request base DN and the workflow naming context. The QoS policy set for Network Group 2 gives restricted access to Workflow 1, for anyone that is not admin. Memory backend workflow element: This comprises the memory local backend workflow elements. Depending on the bind DN, a search would be routed through Network Group 1 or Network Group 2. Oracle Unified Directory has several preconfigured workflow elements that should not be modified or deleted. An operation must comply with the network group QoS policies regardless of the server profile, directory server or proxy server. The main purpose of the replication gateway is to facilitate migration from an existing Oracle Directory Server Enterprise Edition deployment to an Oracle Unified Directory topology. For high availability, two replication gateway servers are deployed in every transition scenario. For more information about the synchronization procedure, see the chapter "Integrating with Oracle Directory Server Enterprise Edition (Connected Directory)" in the Oracle Fusion Middleware Administrator's Guide for Oracle Directory Integration Platform. To initialize an Oracle Directory Server Enterprise Edition topology with data from an Oracle Unified Directory server, the data must be exported from the Oracle Unified Directory server and then imported to an Oracle Directory Server Enterprise Edition master server. To ensure that requests that fail to the first server are treated by the backup server, you must ensure that all the clients know the addresses for both data sources, and are coded to treat a failure on the primary server by re-sending the request to the backup server. The first network group ng1 contains two workflows while ng3 contains a single workflow. To deploy a highly available directory service, you must have at least two replicated directory servers. Therefore, if the bind DN is dc=example,dc=com, then the requests will be forwarded to Workflow 1.

The replication gateway does provide a filtering option, for replication from Oracle Directory Server Enterprise Edition to Oracle Unified Directory. For more information about ACIs, see Chapter 9, "Understanding the Oracle Unified Directory Access Control Model. A client request pursues the following path: The request handlers place the incoming LDAP requests in the work queue from where the worker thread grabs them. As such, it centralizes all the rules for client connections, including handling load balancing, data distribution and security with the data source. ", Chapter 11, "Understanding the Proxy Functionality. This section provides a brief overview of the directory server component of Oracle Unified Directory server. If you want the Oracle Unified Directory server to replicate information between Oracle Unified Directory and Oracle Directory Server Enterprise Edition, then install Oracle Unified Directory as a replication gateway. You can also add virtual ACIs in this group, which implies that you must specify Local Backends as the access control group for the workflow for which virtual ACIs are disabled. This chapter includes the following topics: Section 5.1, "Oracle Unified Directory Components", Section 5.2, "Architecture of Oracle Unified Directory". The tree of workflow elements determines the processing to apply on an operation. EUS context workflow element: This comprises the EUS context workflow elements. The replication gateway does not ensure that schema is coherent across the disparate servers. The replication gateway is responsible for propagating changes made on the disparate servers to the entire replication topology. The administrator must define coherent schema. The administrator must define coherent schema. If the client connection matches the criteria of a network group, but not the QoS policies of that network group, the connection is not forwarded to the workflow, nor is it sent to the next network group. If you want to create an LDAP directory server that contains directory data, then install Oracle Unified Directory as a directory server. ", Section 1.2, "Overview of Directory Server", Section 1.4, "Overview of the Replication Gateway". An administration connector that manages all administration traffic to the server. A graphical control panel that displays server status information and enables you to perform basic server and data administration. The Oracle Directory Server Enterprise Edition server retains the value of the last modify/add operation while the Oracle Unified Directory server retains the oldest value. The minimum version for this migration to succeed is Oracle Directory Server Enterprise Edition 11g Release 1 (11.1.1). A network group can be associated with one or more workflows, each workflow corresponding to a different naming context. You can choose one of the following installation types when installing Oracle Unified Directory: Section 1.1.2.1, "Setting Up the Directory Server", Section 1.1.2.2, "Setting Up the Proxy Server", Section 1.1.2.3, "Setting Up the Replication Gateway Server".

Total update is not supported through the replication gateway. The default values that are configured for filtering account for differences in CoS, roles, password policies, and conflict resolution. ", Section 1.1.2, "Oracle Unified Directory Installation Types. If a network group has no workflows attached to it, the request is not handled. For single-valued attributes, if different values are added simultaneously to the same single-valued attribute, then the Oracle Directory Server Enterprise Edition server and the Oracle Unified Directory server handle the conflict in different ways. Translations are managed "on the fly" without storing any data on disk. As illustrated in Figure 5-1, the request is first sent to the network group with the highest priority: Network Group 1. ", Description of ''Figure 5-2 Client Request for a Directory Server'', Description of ''Figure 5-3 High-Level Presentation of Oracle Unified Directory Components''. The proxy manages all the connections between a client and a data source (be it a single server, replicated server, or data center). Network groups handle all client interactions and dispatch them to local backend workflows or proxy workflows, based on: Criteria can include security authentication level, port number, client IP mask, client bind DN, bind ID, domain name, and other criteria. The tree of workflow elements determines the processing to apply on an operation.
