This chapter describes how to use the Liquid Data Console to configure BEA Liquid Data for WebLogic.
The chapter contains the following sections:
The Liquid Data Console is a web-based administration interface specifically designed for managing and using Liquid Data applications. You can use the console to set security and caching policies for data services, and configure Liquid Data runtime settings such as thread usage and logging levels.
The Liquid Data Console also provides access to the Liquid Data Metadata Browser. The Metadata Browser provides information useful to both Liquid Data administrators and application developers. Developers can see what data services are available, what information they provide, how to call them, and more. Administrators can determine the effects of changes to the data source layer in the console.
Note: For more information, see Viewing Metadata.
Figure 4-1 shows the main page of the Liquid Data Console.
Figure 4-1 Liquid Data Console
The Liquid Data Console is a web-based interface that enables you to administer and manage Liquid Data applications, access metadata, and configure security and caching policies.
To launch the Liquid Data Console:
For more information, see Starting the WebLogic Server.
http://hostname:port/ldconsole
hostname is the machine name or IP address of the host serverport is the address of the port on which the host server is listening for requests (7001 by default)For example, to start the Liquid Data Console on a local instance of WebLogic Server (running on your own machine), navigate to the following URL:
http://localhost:7001/ldconsole/
You can navigate to the various pages in the Liquid Data Console using the tree in the Navigation pane. The administration pages are organized by application and data service, as shown inFigure 4-2.
The following describes the actions you can perform using the Navigation pane:
Console Access Control. Enables you to configure the access control policies that specifies who can access particular console features. Clicking Administration or Metadata Browser displays the Policy Editor, enabling you to specify Policy Statements defining access. For more information, see Using the WebLogic Policy Editor.
Domains. Expand to display the Liquid Data applications in the domain. Alternatively, you can click a domain name to display the list of applications in the Content pane. Right-click and choose Search in the context-sensitive menu to search metadata in the domain (see Searching Metadata on page 8-8).
Applications. Expand to display the Data Services folder. Alternatively, you can click the application name to display the general application settings in the Content pane. For more information, see General Application Settings. Right-click and choose Search in the context-sensitive menu to search metadata in the application (see Searching Metadata on page 8-8).
Data Services. Expand to display the data service project folders in the application. Alternatively, you can click the Data Services folder to display the list of project folders in the Content pane. Right-click and choose Search in the context-sensitive menu to search metadata in the data services (see Searching Metadata on page 8-8).
Project Folder. Expand to display specific data services contained in the project folder. Alternatively, you can click a project folder to display the list of data services in the Content pane. For more information, see Displaying Application Data Services. Right-click and choose Search in the context-sensitive menu to search metadata in the project folder (see Searching Metadata on page 8-8).
Specific Data Service. Expand to display the functions that comprise the data service. Alternatively, you can click a specific data service to display the administration screen for the functions in the Content pane. For more information, see Examining Data Service Functions.
Function. Click to display information about the function in the Content pane, including general information, dependencies, where the function is used, properties, and the return type. For more information, see Displaying Function Details. Right-click and choose Define Security Policy in the context-sensitive menu to create a security policy for the function using the WebLogic Policy Editor (see Understanding Security Policies on page 6-5).
You can display the data services available to an application, along with information about each data service.
To display the data services associated with an application:
The list of data services contained in the project folder appears in the Content pane, as illustrated in Figure 4-3.
Figure 4-3 Data Services Available to a Project
Table 4-1 describes the information presented for each data service.
You can examine the functions that comprise a data service, and manage the cache and security settings, as required. You can also view metadata associated with a data service.
To display the functions that comprise a data service:
An administration screen for the functions in the data service appears in the Content pane, as illustrated in Figure 4-4. For more information about administering data service functions, seeSetting Up Caching, Securing Data Service Functions, and Understanding Data Service Metadata.
Figure 4-4 Data Service Functions
There are two types of functions identified in the Navigation tree, as described in Table 4-2.
|
Navigation function, which return data from a related data service. |
|
|
Read function, which return data in the form of the data service type. |
You can display information about specific functions, including general information, dependencies, where the function is used, properties, and the return type. To display details about a function:
Metadata associated with the function appears in the Content pane, as illustrated in Figure 4-5. For more information, see Displaying Function Metadata.
The Liquid Data Console is a securable resource from the perspective of WebLogic Security. You can set access control policies that defines who can view and use particular pages in the console. The features are distinguished by two functional categories:
For information on controlling access to resources in the console, see Securing Liquid Data Resources.
