Oracle 9i Web-based management

The principle of 5.5.1 based on web management
1. Client
The client operating system is Windows 2000, Windows 98, or Windows NT, installing IE over 5.0 browsers, installing the Java plug-in Oracle Jinitiator 1.1.8.10 and the applet technology-based Enterprise Manager.
2. Middle Layer
Install the Management Server and the Apache HTTP server.
3. Database server
Install the database server and run the smart agent.

5.5.2 How to build an environment based on web management
There are 4 steps to building a web-based management environment.
On the database server-Start Smart agent.
Start the Management Server-start the background service.
On the Web server-starts the Apache HTTP server.
On the administrative client-install Java Plug-ins and applet Enterprise Manager.
5.5.3 on the database server-start the smart agent
1. Test whether the "smart agent" starts
(1) as shown in Figure 5.44.
(2) The listener will communicate as set with the "Smart Agent" on the database server, as shown in Figure 5.45.


2. "Smart Agent" to start unsuccessful solution

5.5.4 on the Manage server-start the background service
Start a background service operation on the Manage server participate in the contents of Section 3.2.3 of this book.
5.5.5 on the Web server-start Apache HTTP Server
1. Test Apache HTTP Server is enabled

2. How to adjust the port of Apache HTTP Server
Httpd.conf: Provides the most basic server configuration.
ACCESS.CONF:ACCESS.CONF is used to configure access rights for the server and to control access restrictions for different users and computers.
Srm.conf:srm.conf is the server's resource mapping file, which tells the server the MIME types of the various files and how to support these files.
(1) Use any text editing software (such as "notepad", etc.) to open the httpd.conf file, the "#" symbol at the beginning of the annotation statement removed, which mainly related to the port configuration code as follows.
―――――――――――――――――――――――――――――――――――――
Port 80
Listen 80
―――――――――――――――――――――――――――――――――――――
(2) Modify these two 80 to the value you want to modify (such as 8888), and then restart the Apache server, using the browser access, found that has been modified successfully.
3. How to adjust the management port of Apache HTTP Server
The Oracle HTTP server provides the ability to manage the database server through IE, using the default port of 3339.
In IE browser "Address bar" input http://11.122.132.188:3339/emwebsite_zh_CN.html, this is the Chinese home page file, appear as shown in Figure 5.48 interface, here can launch the web-based management functions.

(1) This book's database server is installed in the C:/oracle directory, so the Web-managed Web site content stored in the directory is c:/oracle/ora90/oem_webstage.
There is a text profile named oem.conf in the directory where you can modify the port settings as follows.
――――――――――――――――――――――――――――――――――――――


――――――――――――――――――――――――――――――――――――――
The listener listen is a class of programs that receive client information, and the Oracle HTTP server handles various Web requests by setting up listeners with different port numbers.
(2) The above two sentences 3339 can be modified to the port number you need, such as modified to:
――――――――――――――――――――――――――――――――――――――
Listen 4000
<virtualhost _default_:4000>
――――――――――――――――――――――――――――――――――――――
Restarting the Apache server will provide Web services in accordance with the new port settings, typically without changes.
4. How to shut down and start the Apache HTTP server
(1) The interface shown in Figure 5.49.

(2) as shown in Figure 5.50.

5.5.6 on managing clients-installing Java Plug-ins and applets Enterprise Manager
1. Download Oracle Jinitiator Plugin
2. Install Oracle Jinitiator Plugin
(1) Double-click the Jinit11810.exe file to appear as shown in Figure 5.51, "Installation" interface.

(2) The "Welcome" interface appears as shown in Figure 5.52.
(3) The "Install Path" interface appears as shown in Figure 5.53.

(4) The "Finish" interface appears as shown in Figure 5.54.

3. Configure Oracle Jinitiator Plugin
(1) The "Basic" tab of the Jinitiator property, shown in Figure 5.55, is generally not required to be changed.

(2) Figure 5.56 shows the "Advanced" tab of the Oracle Jinitiator property.
(3) Figure 5.57 shows the "proxies" tab of the Oracle Jinitiator property.

4. Install applet "Enterprise Manager"
(1) Enter http://192.168.100.89:3339/emwebsite_zh_CN.html in the browser and appear as shown in Figure 5.58.

(2) The first use will appear as shown in Figure 5.59, "The Hint Information" interface.

(3) Select the Tools/Internet Options option in the browser's menu bar, and select the Security tab of the Internet option as shown in Figure 5.60.
(4) The Oracle Java Console applet interface, shown in Figure 5.61, does not close the interface shown in Figure 5.61 throughout the web-based management process.

(5) The installation Oracle "Enterprise Manager" component interface, as shown in Figure 5.62, appears.

(6) After installation, the "web-based console Login" interface, as shown in Figure 5.63, differs from the login interface of the management console in the Integrated management environment.

(8) The Web-based Enterprise Manager interface, as shown in Figure 5.64, shows a less integrated tool for service management in the Integrated management tool area than the Enterprise Manager for specially installed client management programs.
