This section contains the following information about data views and how to create and configure them:
The examples in this section assume that the connection handler allows all client connections to be processed by Directory Proxy Server.
This section describes how to configure a data view that provides a single point of access to different parts of a subtree. This example contains two data views with the same base DN. A numeric distribution algorithm is used to separate entries into different data views. A data source pool is configured for each set of data-equivalent data sources. The following figure shows the example deployment.
For information about this type of deployment, see Data Views to Route Requests When Different Parts of a Subtree Are Stored in Different Data Sources in Oracle Directory Server Enterprise Edition Reference.
Figure 21-1 Sample Deployment That Provides a Single Point of Access When Different Parts of a Subtree Are Stored in Different Data Sources
You can use DSCC to perform this task. For information, see Directory Service Control Center Interface and the DSCC online help.
For information, see Configuring Load Balancing.
$ dpconf set-ldap-data-view-prop -h host1 -p 1389 dataview-1 \ ldap-data-source-pool:data-source-pool-1 base-dn:ou=people,dc=example,dc=com \ distribution-algorithm :numeric numeric-attrs:uid numeric-lower-bound :0 \ numeric-upper-bound :99
$ dpconf set-ldap-data-view-prop -h host1 -p 1389 dataview-2 \ ldap-data-source-pool:data-source-pool-2 base-dn:ou=people,dc=example,dc=com \ distribution-algorithm:numeric numeric-attrs:uid numeric-lower-bound:100 numeric-upper-bound :199
The other properties of the data views are the same as the default data view in Default Data View.
For information about restarting Directory Proxy Server, see To Restart Directory Proxy Server.
This section describes how to configure a data view to combine hierarchy with distribution algorithms. For information about this type of deployment, see Data Views With Hierarchy and a Distribution Algorithm in Oracle Directory Server Enterprise Edition Reference.
The example in this section contains four data views. The base DN of data view 1 is superior to the base DNs of the other data views. Data view 3 and data view 4 have the same base DN, but a numeric distribution algorithm separates the entries into different data views.
Directory Proxy Server automatically excludes a subordinate branch of a subtree from a data view when the subordinate branch is configured as the base DN of a separate data view. A numeric distribution algorithm separates entries from the same subtree into different data views. A data source pool is configured for each set of data-equivalent data sources.
The following figure shows the example deployment.
Figure 21-2 Sample Data View With Hierarchy and a Distribution Algorithm
You cannot use DSCC to perform this task. Use the command line, as described in this procedure.
Attach the data sources that contain dc=example,dc=com to data-source-pool-1.
Attach the data sources that contain ou=computer,dc=example,dc=com to data-source-pool-2.
Attach the data sources that contain entries in ou=people,dc=example,dc=com with uid between 0 and 99 to data-source-pool-3.
Attach the data sources that contain entries in ou=people,dc=example,dc=com with uid between 100 and 199 to data-source-pool-4.
For information, see Configuring Load Balancing.
$ dpconf create-ldap-data-view -h host1 -p 1389 dataview-1 \ data-source-pool-1 dc=example,dc=com
$ dpconf create-ldap-data-view -h host1 -p 1389 dataview-2 \ data-source-pool-2 ou=computer,dc=example,dc=com
Subtree operations accessing dataview-1, will span to dataview-2. In some cases it could be useful to disconnect a subordinate data view from its parent in order to prevent subtree operations from spanning to it. To avoid subtree operations on dataview-1 from spanning to dataview-2, disconnect it from its parent. Example:
$ dpconf set-ldap-data-view-prop -h host1 -p 1389 dataview-2 connect-to-parent:false
$ dpconf create-ldap-data-view -h host1 -p 1389 dataview-3 \ data-source-pool-3 ou=people,dc=example,dc=com $ dpconf set-ldap-data-view-prop dataview-3 distribution-algorithm:numeric \ numeric-attrs:uid numeric-lower-bound:0 numeric-upper-bound:99
$ dpconf create-ldap-data-view -h host1 -p 1389 dataview-4 \ data-source-pool-4 ou=people,dc=example,dc=com $ dpconf set-ldap-data-view-prop dataview-4 distribution-algorithm:numeric \ numeric-attrs:uid numeric-lower-bound:100 numeric-upper-bound:199
$ dpconf get-ldap-data-view-prop -h host1 -p 1389 dataview-1 excluded-subtrees
The list of excluded subtrees is returned.
