Configuring Message Server as a Standalone Node

Stopping Standalone Message Server

To stop a connected Standalone Message Server, click ‘Stop Server’ on the Console. To exit from

the Console, click ‘Logout’.

In the Server Administration Service Home page, the ‘Connect’ option changes back to ‘Start’.

Note: You must refresh the main page to verify the status.

Removing Standalone Message Server

You can remove a Standalone Message Server only if it is not running. To remove a server:

1 On the Server Administration Service Home page, select the server that is to be removed.

2 Click ‘Delete’.

Using Loaded Send Queues

Loaded Send operation in Pramati Message is used in situations where there is a fast sender and a

slow receiver. Normally, messages are kept in-memory. If the number of messages that are sent are

increased, this may increase the memory usage infinitely. There are two ways to overcome this

limitation:

• Setting Max Queue Size based on the application activity

•Loaded Send

Setting the max queue size to the maximum possible value based on the activity of the application

however has its disadvantages. Here the client cannot send messages beyond the maximum size

specified, in case messages cross the max limit.

To overcome this, the loaded send queues can be used. In the next section we will discuss how to

configure the Message Server for loaded queues.

Configuring the Message Server for Loaded Queues

The following components are required to configure the Message Server for loaded queues.

• A properties file

• A temporary store for storing messages in a database table

The loaded send feature uses a property file (loadedsend.props) where the maximum and

minimum number of messages that can be maintained are specified. This file can be placed

anywhere. The server should be started with the following system property specifying the path to the

properties file:

-Dcom.pramati.loadedsendprops = <path>/<to>/<the>/<loadedsend.props file>

Here is how the loadedsend.props property file looks:

queues=JMSQueue,SellQueue

minruntimesize=100

maxruntimesize=2000
