The ias_admin User and Restrictions on its Password

Oracle Application Server Installation Guide

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.

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

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

.

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.

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.
