Oracle Weblogic Server: Exploring the Installation Directories

We have two major home directories—Oracle Middleware Home and Oracle WebLogic Server Home. The Oracle Middleware Home directory is where all the WebLogic Server and other middleware product files are located—it's the top-level directory for all Oracle Fusion Middleware products, including the Oracle WebLogic Server. See Middleware Home Directory as below
Directory	Contents
/coherence_3.6	Home Directory for Oracle Coherence
/jdk160_21	Directory for the default Sun JDK
/jrockit_160_22_D1.1.1-3	Directory for the JRockit JDK
/logs	Location for various log files, including those for WLST
/modules	Location for modules such as Apache Ant
/oepe_11gR1PS3	Files related to Oracle Enterprise Package for Eclipse
/user_projects	Standard location for domains
/utils	Various utilities such as cloning scripts and QuickStart
/wl_server_10.3	WebLogic Server Home directory

WebLogic Server Home

The WebLogic Server home is simply the directory where I installed WebLogic Server, and by default it's located in the MW_HOME\wlserver_10.3 directory. You refer to this home as the WL_HOME directory, distinguished from the Oracle Middleware Home directory, which in my example is C:\MyOra\Middleware. Thus, the complete path of the WebLogic Server home is C:\ MyOra\Middleware\wlserver_10.3.

Under the WebLogic Server Home (WL_HOME), you'll find the following directory structure:

/bugsfixed

/common

/inventory

/samples

/server

/sip

/uninstall

The bin directory under the WL_HOME server directory contains the startNodeManager script to start up the Node Manager. Under the /samples directory you'll find the default domains installed by the Oracle Installer with the help of the WebLogic Server Configuration Wizard when you chose to install the examples during the installation process. There are three such domains, all located under the /samples directory. The domains are actually in the WL_HOME/samples/ domains directory. When you open this directory, you'll find three domain directories, one for each of the domains the installer creates for you. These are the medrec, medrec-spring, and wl_ server domains. The next section explores the contents of these domain directories, all of which have the same structure.

WebLogic Server Domain Directory

Each domain that you create will have the following directory structure:

/bin

/config

/console-ext

/init-info

/lib

/nodemanager

/security

/servers

Under the /bin directory of each domain is where you'll find the various scripts to start and stop the Admin and Managed Servers, such as startWebLogic.cmd and stopWebLogic.cmd. Note that UNIX versions of these scripts are also located in this directory.The all-important domain configuration file, config.xml, is stored in the /config directory.
