Enterprise application settings
Use this page to configure an enterprise application.
To view this administrative console page, click Applications > Enterprise
Applications > application_name.
Configuration tab
- Name
- Specifies a logical name for the application. Application names
must be unique within a cell and cannot contain characters that are not allowed
in object names.
- Starting Weight
- Specifies the order in which applications are started when the
server starts. The application with the lowest starting weight is started
first.
| Data type |
Integer |
| Default |
1 |
| Range |
0 to 100 |
- Application Binaries
- Specifies the directory to which the application EAR file will
be installed. The default value is the value of APP_INSTALL_ROOT/cell_name,
where the APP_INSTALL_ROOT variable is install_root/installedApps;
for example, C:\WebSphere\AppServer\installedApps\cell_name.
You can specify an absolute path or use a pathmap variable such as ${MY_APPS}.
Use a pathmap variable in any installation
though it is particularly needed when installing an application on a cluster
with members on heterogeneous nodes because, in such cases, there might not
be a single way to specify an absolute path. A WebSphere Application Server variable ${CELL}
that denotes the current cell name can also be in the pathmap variable;
for example, ${MY_APP}/${CELL}.
- Use Metadata From Binaries
- Specifies whether the application server uses the binding, extensions,
and deployment descriptors located with the application deployment document,
the deployment.xml file (default), or those located in the enterprise application
resource (EAR) file.
| Data type |
Boolean |
| Default |
true |
- Enable Distribution
- Specifies whether WebSphere Application Server expands or deletes application binaries
in the installation destination. The default is to enable application distribution.
Application binaries for installed applications are expanded to the directory
specified. The binaries are also deleted when you uninstall and save changes
to the configuration. If you disable this option, then ensure that
the application binaries are expanded appropriately in the destination directories
of all nodes where the application runs.
| Data type |
Boolean |
| Default |
true |
- Classloader Mode
- Specifies whether the class loader searches in the parent class
loader or in the application class loader first to load a class. The standard
for JDK class loaders and WebSphere Application Server class loaders is PARENT_FIRST. By specifying
PARENT_LAST, your application can override classes contained in the parent
class loader, but this action can potentially result in ClassCastException
or LinkageErrors if you have mixed use of overridden classes and non-overridden
classes.
The options are PARENT_FIRST and PARENT_LAST. The default is to search
in the parent class loader before searching in the application class loader
to load a class.
| Data type |
String |
| Default |
PARENT_FIRST |
- WAR Classloader Policy
- Specifies whether to use a single class loader to load all WAR
files of this application or to use a different class loader for each WAR
file.
The options are APPLICATION and MODULE. The default is to use a separate
class loader to load each WAR file.
| Data type |
String |
| Default |
MODULE |
- Create MBeans for Resources
- Specifies whether to create MBean files for various resources (such
as servlets or JSP files) within an application.
| Data type |
Boolean |
| Default |
true |
- Reload Enabled
- Specifies whether to enable class reloading when application files
are updated.
| Data type |
Boolean |
| Default |
true |
- Reload Interval
- Specifies the number of seconds to scan the application's file
system for updated files. The default is the value of the reload interval
attribute in the IBM extension (META-INF/ibm-application-ext.xmi) file of
the EAR file. This setting takes effect only if class reloading is enabled.
The reload interval specified here overrides the value specified in the
IBM extensions for each Web module in the EAR file (which in turn overrides
the reload interval specified in the IBM extensions for the application in
the EAR file).
