New: Improved installation and configuration, with profiles
This topic describes how the product directory structure and use of profiles separates the binary system files from the installation-specific configuration information, leading to easier installation, maintenance, and configuration management.
The v6.x product installation program places the files it creates into one of two separate environments. It installs the binary system files that may be read-only. It also creates an initial profile, which is a run-time execution environment that includes configuration files, the default location for deployed applications, logs, and other data. All profiles on a machine can share the same system files, but do not change the system files.
Administrators can use any of the administrative clients to administer the configuration of each profile. It is highly recommended that you browse wasprofile command for a full introduction to profiles.
Administrators must now address commands to particular profiles System administrators of multiple Application Server instances on a single machine should note the following change. System administration commands are now profile-specific. In previous releases, commands were executed from the bin directory of the product installation root. Now commands must be executed from a particular profile/bin directory. For example, use the -profileName parameter to identify which Application Server to start.
For various ways to address profiles, see Using the Profile creation wizard to create a deployment manager.
Profiles can be exported We can propagate the configuration from one profile to another by exporting a profile to a configuration archive and importing it to another profile. This mechanism works between profiles of the same installation or different installations. A restriction is that this mechanism only works for an unfederated profile.
For more information, see Working with server configuration files.
Profiles sharing the same system files may be upgraded (or rolled back) individually. Because the v6.x binary images are installed at a different location, it is possible to upgrade each v5 profile individually.
Directory structure changes Files pertaining to a particular application server runtime environment are in a directory path containing the word profiles, as well as the particular profile name.
Note also that the product installation root has changed to include IBM, as described in What is new for installers.
