VBScript:
VBScript is another Microsoft product that is often
used to add functionality to the Web browser. Like JavaScript,
VBScript code is often embedded in Web pages. Invocation and
execution are also similar to JavaScript.
•
Cookies:
Cookies are used to expedite user requests when the
user visits a site more than once. When the site is first visited,
the Web server creates a cookie with basic user information
(such as e-mail) and sends it to the browser. When the browser is
subsequently used to visit that site, the cookie, upon recognition
by the Web server, is used to expedite the user request.
25.4 Implementation with Oracle
Oracle implements a database that is by definition, Web-accessible (this applies since
Oracle 10G). This is achieved through the products Oracle Enterprise Manager, (OEM),
iSQL*Plus, Oracle JDeveloper, and Oracle SQL Developer in the following ways:
•
When you install the Oracle Server suite (including OEM) on
a node in your company or home network, the machine is
automatically configures as a database server.
•
Oracle automatically installs and configures a database listener
on database server to respond to incoming requests from client
nodes (running Oracle 10G or 11G Client) in the network, on the
internet, or an extranet.
•
Typically, your database server should have at least one database.
This can be created during installation, or subsequently via the
Oracle Database Configuration Assistant (DBCA) component.
•
You can access your database server from any machine
that has an internet connection, through OEM via the URL
http://<Machine.Domain>:5500/em
(you supply the machine
name and domain name for your network). Of course, you will
need a valid user account, password, and appropriate privileges.
•
You can also access your database server from any machine that
has an internet connection, through Oracle's iSQL*Plus via the
URL
http://<Machine.Domain>:5560/isqlplus
(again, you
supply the machine name and domain name for your network).
Again, you will need a valid user account, password, and
appropriate privileges.
•
Through Oracle JDeveloper (OJD), Oracle allows Web-accessible
Java-based applications to be constructed. These applications
may access local or remote Oracle (or heterogeneous) databases.
