Setting up Presentation Server Parameters
The Parameters node in the Explorer window allows you to set up configuration information for this server.
There are three types of properties used in the Presentation Server Administration Tool:
Implicit properties,
Explicit properties,
External properties.
Implicit properties can be thought of as a short cut for referring to information defined elsewhere in the Presentation Server Administration Tool. They are only available to use within the Parameters node in the Explorer window. They are created mainly from the information for the local Server, under the Servers node. In particular, the available implicit properties are:
_se.context:refers to the value defined in the CONTEXT of the local server.
_se.server.name: refers to the value defined in the NAME of the local server.
_se.server.path: refers to the value defined in the PATH of the local server, which is usually a combination of the CONTEXT and the "/servlet/" text. Thus if the context is "/altio", the path will be "altio/servlet/".
_se.server.port: refers to the value defined in the PORT of the local server.
_se.server.protocol: refers to the value defined in the PROTOCOL of the local server.
_se.request.secure: set from the Secure Request property under Server Settings.
_se.param.secure: controls whether SyncEngine parameters are transmitted securely or not.
The set of properties available defined in this section, also referred to as explicit properties, can be used in many locations throughout the Presentation Server configuration. These properties are especially useful in setting up service definitions in the Applications Manager. To refer to a property defined in this section, use the syntax of ${my.property.name} where my.property.name is the name of the parameter.
By default there are two sets of explicit properties defined in this section:
http properties: used by our sample login process to configure the URL to which the client applet connects.
db properties: used by our sample applications to configure the application service functions to retrieve data.
Both sets of properties pick up the appropriate implicit properties by default, and so evaluate to the same strings. However, having them separate means that it is possible to configure the URL the clients use to connect (for example: to go to a load balancer) separately from where the data is picked up from.
To ease configuration management, it is possible to define as many custom properties in this section as you wish.
For convenience, any context-param entries defined in web.xml are also available as server properties. This allows you to deploy AltioLive on a number of servers (in a cluster for example) and have slightly different application configurations without changing altioserver.xml. If a property of the same name exists in altioserver.xml, it will override the context-param property. Many application servers have their own configuration interface for changing context-param and other settings for a web-application. See your application server documentation for details.
Name: Name of the property (parameter).
Value: Value of the property. Explicit and External properties may reference implicit properties in their values.
Encrypt (Y | N): Indicate the parameter value shall be encrypted when it is saved back to configuration file.
