The FileNet® P8 domain
contains the entities that represent the Content Platform Engine physical resources
(such as object stores) as well as the Content Platform Engine servers that provide
access to those resources.
Although there is no limit to the number of entities a
single
FileNet P8 domain
can contain, there are practical and performance issues to be considered.
These issues, if applicable, are discussed in the help topics that
are related to each entity.
- Site
- A site is a geographical location where resources are connected
through a local area network. Object stores, storage areas, content
cache areas, index areas, and virtual servers are associated with
an individual site. As virtual servers, server instances, and other
resources are added to the domain, they are assigned to the default
site, unless a different site is explicitly specified. A user with
system administrator privileges can change the site that is used as
the default.
- Virtual server
- A virtual server is the logical service point that Content Platform Engine clients interact with.
Virtual server objects are created dynamically during system initialization
and startup that is based on the configured topology of the Java™ EE application server. (The
topology is the physical or logical mapping of the location of networking
components or nodes within a network.) A virtual server can contain
one or more server instances. Applications accessing the virtual server
are unaware of the number or type of server instances that reside
behind the virtual server.
- Server instance
- A Content Platform Engine server
instance is an individual Java Platform,
Enterprise Edition (Java EE)
application server instance. Multiple server instances, each running
in their own Java virtual machine
(JVM), can be hosted on a single physical server. (Multiple server
instances are a common configuration when large multiprocessor servers
are used.) Content Platform Engine clients
do not interact directly with a server instance; logically, clients
always go through a virtual server. Virtual servers and server instances
are created in the global configuration database when you deploy the Content Platform Engine software on an application
server, but are not removed from the global configuration database
when the Content Platform Engine software
is removed from an application server.
- Database connection
- A database connection combines the connection information to the
database, that is the JNDI XA data source and the JNDI non-XA data
source and the site information. The connection information is used
during the creation of other objects like object stores and isolated
regions.
- Object store
- An object store is a repository for storing objects (such as documents,
folders, and business objects) and the metadata that defines the classes
and properties of objects.
- Index area
- An index area is a container for one or more indexes, which are
used to perform full-text searches against documents in an object
store.
- Storage area
- A storage area is a container for content storage, and can be
configured for file storage, fixed storage, or database storage.
- Fixed content device
- A fixed content device is an external (non-FileNet P8) storage device from an
independent software vendor. This device can be associated with a FileNet P8 fixed storage area.
- Content cache area
- A content cache is a disk area that contains copies of content
recently accessed through a Content Platform Engine server.
Typically used in a geographically distributed environment, it enhances
response time when retrieving content.
- Add-on feature
- An add-on feature is a module that contains custom metadata and
data that support extensions to core Content Platform Engine features. See Add-on
features for more information about the classes and properties added
to the object store during this process.
- Marking set
- A marking set provides a way to define a level of security on
objects in addition to the normal FileNet P8 security model. By using
markings, access to objects can be controlled based on specific property
values.
