Oracle Application Server 10g Administrator's Guide 10g (9.0.4) Part Number B10376-01 |
|
This preface introduces the new administrative features of Oracle Application Server 10g (9.0.4). This information is mostly useful to users who have managed Oracle9i Application Server (Oracle9iAS) Release 2 (9.0.2 and 9.0.3).
The new administrative features of Oracle Application Server 10g (9.0.4) include:
Identity management is the process by which various components work together to manage the security life cycle for networked entities, such as devices, processes, applications, and users. While some of this functionality existed in Oracle9iAS Release 2, it has been enhanced and fully integrated into a new product in Oracle Application Server 10g called Oracle Identity Management.
Oracle Identity Management provides a fine-grained delegation deployment privileges model for deploying middle tiers and Metadata Repositories. You can find information on this in several books, as shown in the following table.
Oracle Identity Management is part of the Infrastructure installation type, and contains the following components:
Oracle Application Server 10g provides the following improvements to the Oracle Application Server Metadata Repository:
Note that both of the above methods support installing a Metadata Repository that is registered or not-registered with Oracle Internet Directory.
The Infrastructure installation type is divided into two distinct pieces:
Oracle Application Server 10g provides greater flexibility for installing an Infrastructure:
Because the Infrastructure is divided into these two pieces that provide different services, it is often too imprecise to refer to the Infrastructure as a whole when discussing administrative operations. For example, a middle-tier instance may use Oracle Identity Management in one Infrastructure installation, and the OracleAS Metadata Repository in another Infrastructure installation. In this case, it is not accurate to refer to the "Infrastructure" used by a middle-tier instance. You will notice that Oracle Application Server 10g tools and documentation often refer specifically to the Oracle Identity Management installation or OracleAS Metadata Repository used by a middle-tier instance.
The Oracle9iAS Oracle Enterprise Manager Web site has been renamed to Oracle Enterprise Manager 10g Application Server Control (Application Server Control, for short).
Application Server Control is installed and configured in every Oracle Application Server installation. Each installation has its own ias_admin
password and uses a different port for Application Server Control. There is no primary Oracle home and no emtab
file.
Application Server Control includes the following enhancements:
opmn.xml
Chapter 8, "Changing Infrastructure Services" and Chapter 6, "Managing an OracleAS Metadata Repository"
See Also:
emctl
command has new syntax
OPMN has expanded to provide process management and monitoring for most Oracle Application Server components, and opmnctl
is the primary command-line tool for starting and stopping.
opmnctl
command to start all of the components in an application server instance in the proper order.
opmnctl
command has expanded--you can start a specified instance in the farm, all instances in the farm, and Oracle Application Server clusters.
opmn.xml
file has changed to provide more power and flexibility for configuring Oracle Application Server. You can edit the opmn.xml
file manually or using the Process Management page in Application Server Control.
In Oracle Application Server 10g, DCM and the dcmctl
command provide many new features, including:
saveInstance
and restoreInstance
commands, plus much more.
dcmctl
command and Application Server Control can be used together. There is no need to disable one while you are using the other, as in Oracle9iAS Release 2.
-v
and -d
options are enabled for every dcmctl
command. This provides useful error messages and diagnostic output. Oracle recommends you always use the -v
and -d
options, however, you can enable and disable them using the dcmctl set
command.
For security purposes, the following SSL ports are not enabled during installation--you can selectively enable them after installation:
The opmnctl
command now starts and stops most Oracle Application Server components, in the proper order. This has greatly simplified starting and stopping an Oracle Application Server instance.
Oracle Application Server 10g provides the following new tools for viewing log files:
printlogs
--a command-line tool that reads and filters log messages and prints them to standard output in a single format
Oracle Application Server 10g provides the following improvements for managing ports:
staticports.ini
) and launching Oracle Universal Installer with special options. This is supported for most port numbers.
You can change the Oracle Identity Management installation or OracleAS Metadata Repository used by a middle-tier instance after installation.
Oracle Application Server 10g offers a new tool (chgiphost.sh
) that allows you to update Oracle Application Server installations when you change the hostname or IP address of your host.
Oracle Application Server 10g offers complete backup and recovery procedures for your Oracle Application Server environment, along with an Oracle Application Server Backup and Recovery Tool.
Oracle Application Server 10g offers many high availability solutions, including:
