The Application Server Control tool is the main administrative console for Oracle Application Server. An Application Server Control instance is installed in each application server home and provides a web-based interface for administering that application server. Figure 3-1 shows the Application Server Control home page. Figure 3-1. Application Server Control home pageFrom the home page, you can:
For example, you can examine the Log Repository (described later) through a Log Viewer by selecting the Logs link appearing in the upper right on this page. Application Server Control provides a wide spectrum of capabilities. The following sections look at a few typical administrative functions available through this tool. 3.1.1 Application Server Control Management StackThe Application Server Control management stack that enables the management functions you can perform with Application Server Control consists of the following services, introduced in Chapter 2:
Application Server Control uses these facilities in a variety of ways. For example, you can use Application Server Control to configure the two key Oracle Application Server business intelligence components, OracleAS Discoverer and OracleAS Reports Services. You can also monitor OracleAS Reports Services performance, and can view and manage OracleAS Reports Services job queues. 3.1.2 Managing PortsYou can use Application Server Control to reconfigure ports, used by Oracle Application Server components and services, and allocated during installation. You can also view or change these ports. Links to the Oracle Application Server documentation make it easy to prevent conflict with other ports on your system by determining ports that may be affected by your changes. 3.1.3 Viewing and Managing Log InformationDuring normal operation, various Oracle Application Server components populate logs with information ”for example, startup and shutdown information, warnings, and errors. You can use Application Server Control to view this information. Oracle Application Server components that generate log files include:
Using the Logs link in Application Server Control, you can easily search for log files related to any of these components. You can also browse these logs directly from the Application Server Control user interface to help you diagnose problems. You have the option of consolidating log information into a single repository, and doing so simplifies the diagnostic process when you are analyzing multiple components. The Log Loader, started through Application Server Control, initiates and populates the Log Repository. Warning and error messages that are gathered here are used when you troubleshoot problems that can occur in specific Oracle Application Server components. You'll also find these useful when reporting problems to Oracle Support (described in the last section of this chapter). 3.1.4 Administering J2EEYou can perform a variety of J2EE administration functions by invoking the OC4J home page through Application Server Control. These include:
3.1.5 Administering ClustersYou can also use Application Server Control to manage a group of application servers hosting a common set of OC4J applications as a cluster. Setting up a cluster allows you to modify common configuration settings only once for all cluster members . You can also deploy applications across the cluster in a single step. The architecture of clusters is described in Chapter 2. |
