Usage Profiles

Every administrative domain is associated with a usage profile, which identifies the capabilities of that domain. Application Server provides the following profiles:

• Developer: Use this profile if you are running your domain in a development environment and if your applications do not need the NSS keystore or clustering features, such as load balancing, and session persistence.

• Cluster: Use this profile if you need to create clusters but do not require the high-availability database (HADB) or the NSS keystore.

• Enterprise: Use this profile if you need HADB and NSS. This profile is usable only if you install HADB and NSS separately or if you install Application Server as part of the Java Enterprise System (JES). For information on how you can use the enterprise profile with Application Server 9.1, see Using the Enterprise Profile

Note –

Upgrade from Application Server 8.x Enterprise Edition is supported only by the enterprise profile. Use the developer profile if you are upgrading from Application Server 8.x Platform Edition. For more information on the Upgrade process, see Chapter 2, Upgrading an Application Server Installation, in Sun Java System Application Server 9.1 Upgrade and Migration Guide.

---

The domain provides a preconfigured runtime for the user applications. Usage profiles facilitates the distinction between the Application Server binaries and the runtime configuration. Profiles enable you to use the same installation of Application Server to create different domains with profiles that suit specific needs. For example, a developer may want to use the Application Server to get to know the latest Java EE specifications. This developer does not need stringent security settings. Another user who wants to deploy applications in a production environment needs an inherently secure environment.

Table 1–1 lists the features available with each profile:

Table 1–1 Features Available for Each Profile

Feature	Developer Profile	Cluster Profile	Enterprise Profile
Security store	JKS	JKS	NSS
Clustering/Standalone instances	Not available	Available	Available
Security Manager	Disabled	Enabled	Enabled
HADB	Not available	Not available	Available
Load balancing	Not available	Available	Available
Node agents	Not available	Available	Available

Using the Enterprise Profile

To use the enterprise profile, perform the following tasks:

1. Download and install NSS and HADB separately.

2. Modify the asenv.conf file as follows:

   • AS_HADB points to the folder where HADB is installed.

   • AS_NSS points to the folder where NSS shared objects are available.

   • AS_NSS_BIN points to the folder where NSS binaries, such as certutil, are stored.

Upgrading an Earlier Domain to Application Server 9.1

You can use the start-domain command to upgrade Application Server 8.x or 9.0 domains to Application Server 9.1. Use one of the following ways to upgrade your domain:

• Perform an in-place upgrade of the Application Server binaries.

  When you run start-domain on the domains pointing to the earlier version of Application Server, asadmin invokes the asupgrade command , and the domains are automatically upgraded in-place.

• Perform a side-by-side upgrade of the Application Server binaries.

  Run start-domain on the domains of your earlier installation. The asupgrade command upgrades the domains to the domains root of the latest Application Server installation. In this scenario, the target directory for the upgrade is defined in the AS_DEF_DOMAINS_PATH in the asenv.conf.
