3-4 Oracle Application Server Installation Guide
Valid Characters in Instance Names
Instance names can consist only of the alphanumeric characters (A-Z, a-z, 0-9) and the
_
(underscore) character.
The maximum length for an instance name is 64 characters.
Restrictions on Oracle Application Server Instance Names
Do not use the hostname of the computer when naming Oracle Application Server
instances.
If you are planning to place the Oracle Application Server instance in an OracleAS
Cluster, the instance name must not contain the following:
■
hostname or IP address of any computer in the OracleAS Cluster
■
Oracle home of any Oracle Application Server installation in the OracleAS Cluster
How Oracle Application Server Uses Instance Names
Instance names are important because Oracle Application Server uses them to
uniquely identify instances. This means that if you install multiple Oracle Application
Server instances on the same computer (for example, an OracleAS Infrastructure and a
J2EE and Web Cache instance), you must give them different names.
When you administer Oracle Application Server using Oracle Enterprise Manager 10g
Application Server Control (or Application Server Control for short), the instance
name appears on the screens. You can click the instance name to see details about the
instance, such as the components that are installed in that instance, if the components
are running or stopped, and the log files for the components. The Application Server
Control is a browser-based administration tool for Oracle Application Server. See the
Oracle Application Server Administrator’s Guide for details about this administration tool.
In addition, some dcmctl commands require an instance name as a parameter.
dcmctl
is a command-line tool for administering Oracle Application Server instances.
See the Distributed Configuration Management Administrator’s Guide for details about
dcmctl
.
3.6 The ias_admin User and Restrictions on its Password
The installer prompts you to specify the password for the ias_admin user. The ias_
admin
user is the administrative user for Oracle Application Server instances. To
manage Oracle Application Server instances using Application Server Control, you log
in as ias_admin.
On a computer, you can install multiple Oracle Application Server instances, each with
its own unique instance name, but the name of the administrative user is ias_admin
for all instances. The password for the ias_admin user can be different for each
instance.
Password for the ias_admin User
The password for the ias_admin user must conform to Oracle Internet Directory’s
password policy:
■
If you are using the Oracle Internet Directory that is shipped with this release of
Oracle Application Server and you did not change the default password policy,
passwords have the following restrictions:
■
The minimum length is five alphanumeric characters.
■
At least one of the characters must be a number.
