Oracle 9i Web-based management

5.5.1 principles of Web-based management
1. Client
The client operating system is Windows 2000, Windows 98, or Windows NT. the browser with IE 5.0 or above is installed, and the Java Plug-in Oracle JInitiator 1.1.8.10 and the applet-based [Enterprise Manager] are installed ].
2. Intermediate Layer
Install the [Management Server] and Apache HTTP server.
3. Database Server
Install the database server and run [intelligent proxy ].

5.5.2 how to build a web-based management environment
There are four steps to build a web-based management environment.
On the database server-start intelligent proxy ].
Start Management Server> Start background services.
On the web server-start the Apache HTTP Server.
On the management client-install the Java Plug-in and Applet [Enterprise Manager ].
5.5.3 on the database server -- start [intelligent proxy]
1. Test whether [intelligent proxy] is enabled
(1) 5.44.
(2) The Listener communicates with the [intelligent proxy] on the database server according to the settings, as shown in Figure 5.45.


2. [smart proxy] solution to unsuccessful startup

5.5.4 on the [Management Server] -- start the Background Service
Start the operations of background services on the [Management Server] to participate in section 3.2.3 of this book.
5.5.5 on the Web server -- start the Apache HTTP Server
1. test whether the Apache HTTP server is enabled

2. How to adjust the port of the Apache HTTP Server
Httpd. conf: provides the most basic server configuration.
Access. conf: Access. conf is used to configure Server access permissions and control access restrictions for different users and computers.
SRM. conf: SRM. conf is the server's resource ing file that tells the server about the MIME types of various files and how to support these files.
(1) use any text editing software (such as NotePad) to open httpd. in the conf file, remove the annotation statement starting with the "#" symbol. The Code mainly related to port configuration is as follows.
―――――――――――――――――――――――――――――――――――――
Port 80
Listen 80
―――――――――――――――――――――――――――――――――――――
(2) modify the values (such as 8888) for the two 80 s, restart the Apache server, and access the server using a browser. The modification is successful.
3. How to adjust the Management port of the Apache HTTP Server
The Oracle HTTP Server provides the database server management function through IE. The default port is 3339.
Enter http: // 11.122.132.188: 3339/emwebsite_zh_cn.html in the address bar of IE. This is the Chinese homepage file. The page shown in 5.48 appears. You can start various web-based management functions.

(1) The database server of this book is installed in the C:/Oracle directory. Therefore, the directory for storing website content based on Web management is C:/Oracle/ora90/oem_webstage.
There is a text configuration file named OEM. conf in this directory. You can modify the port settings in the file as follows.
――――――――――――――――――――――――――――――――――――――


――――――――――――――――――――――――――――――――――――――
Listen is a program used to receive client information. The HTTP server of Oracle processes various Web requests by setting listeners of different port numbers.
(2) You can change 3339 of the preceding two statements to the port number you need, for example,:
――――――――――――――――――――――――――――――――――――――
Listen 4000.
<Virtualhost _ default _: 4000>
――――――――――――――――――――――――――――――――――――――
Restart the Apache server to provide Web Services based on the new port settings. Generally, no changes are required.
4. How to disable and start the Apache HTTP Server
(1) interface shown in 5.49.

(2) 5.50.

5.5.6 on the management client-install the Java Plug-in and Applet [Enterprise Manager]
1. Download the Oracle JInitiator plug-in
2. Install the Oracle JInitiator plug-in
(1)double hit jinit11810.exe file, the installation page shown in 5.51 appears.

(2) The welcome page shown in 5.52 is displayed.
(3) The "installation path" Page shown in 5.53 is displayed.

(4) The "complete" Page shown in Figure 5.54 is displayed.

3. Configure the Oracle JInitiator plug-in
(1) The basic Tab Of The JInitiator attribute shown in Figure 5.55 does not need to be changed.

(2) Figure 5.56 shows the Advanced tab of the Oracle JInitiator attribute.
(3) Figure 5.57 shows the [proxies] tab of the Oracle JInitiator attribute.

4. Install the applet [Enterprise Manager]
(1) Enter http: // 192.168.100.89: 3339/emwebsite_zh_cn.html in the browser, and the page shown in "5.58" is displayed.

(2) The "prompt information" Page shown in "5.59" appears when you use the service for the first time.

(3) On the menu bar of the browser, select Tools and Internet Options, and select the Security tab of Internet Options shown in 5.60.
(4) The Oracle Java console applet interface shown in 5.61 appears. Do not close the interface shown in Figure 5.61 During Web-based management.

(5) The "Install Oracle [Enterprise Manager] component interface is displayed, as shown in Figure 5.62.

(6) After the installation is complete, the web-based console logon interface shown in 5.63 is displayed, which is different from the logon interface of the Management Console in the integrated management environment.

(8) The web-based [Enterprise Manager] interface shown in 5.64 is displayed. Compared with the [Enterprise Manager] of the customer management program that is specially installed, in the integrated management tools area, there must be one fewer integrated service management tools.
