Managing JMS Server Configuration

In the JMS Server Configuration: Overviewscreen of the SAP NetWeaver Administrator you can view and manage the JMS Provider configuration on the AS

Java. You can create and remove JMS resources (connection factories and destinations) and virtual providers. You can configure their current state as well by

setting their properties in the Details section.

Prerequisites

You have opened the Configuration Infrastructure JMS Server Configuration function of SAP NetWeaver Administrator.

Procedure

Managing JMS Virtual Providers

Select JMS Virtual Providers from the Showdropdown menu.

Creating and Removing JMS Virtual Providers

1. To create a JMS virtual provider, choose Create. In the dialog box that appears, specify the name of the virtual provider and choose Save.

2. To remove a virtual provider, selec t the virtual provider you want to delete and choose the Remove button.

You have to be careful when you delete a virtual provider because this may cause some applications to stop running.

Configuring JMS Virtual Providers

Configuring the Global Default Properties of the JMS Provider Service

You can configure global properties of JMS virtual providers via the Config Tool.

1. Start the Config Tool by double-c licking the configtoolscript file in ///j2ee/configtool

directory and expand the nodes cluster-data template services jms_provider .

2. If necessary, choose View Expert Mode .

3. If you want to distribute all of the JMS virtual providers you have between the server nodes, set the value ofhostMultipleVPs key to true. Otherwise you have

only one virtual provider on a node and if the number of the virtual providers is larger than the nodes, some of the virtual providers are not started and some of

your applications may s top running.

4. To app ly the changes, you have to restart the Application Server clus ter.

Configuring JMS Virtual Providers Locally (per Provider)

1. To manage the properties of a particular JMS virtual provider properties , selec t the provider, then choose Edit.

2. In the Details area, choose the Details tab.

3. Customize the settings, as necessary.

You can also spec ify the local JMS virtual provider properties in the jms-resources.xml deployment descriptor. The following table shows the

correspondence between the online-configurable properties and the jms-resources.xml elements:

Property in SAP NetWeaver Administrator Property in jms-resources.xml

DataSource Name dataSourceName

Running Mode runningMode

Clean Up Service Sleep Interval (milliseconds) cleanUpServiceSleepInterval

Client Memory Size (bytes) clientMemorySize

Client Consumer Buffer Size (bytes) clientConsumerBuffer

Cache Size Limit (bytes) cacheSizeLimit

For more information about the properties you want to configure, see Property Reference.4. To save your changes, choose Save.

Creating and Configuring JMS Resources

1. To create and configure JMS resources, select JMS Resources from the Showdropdown menu. The following table describes the different tasks you can do

Monitoring the JMS Provider

You can monitor the JMS Provider using the SAP NetWeaver Administrator. To access the monitors you have to:

1. Open the SAP NetWeaver Adminis trator and choose Availability and Performance Resource Monitoring History Reports .2. Choose the Monitor Browsertab.

3. Using the Showdropdown list, specify whether you want to display the active or inactive monitors.

JMS Details Description

This is the list of properties that sets up the Topics, Queues, Connection Factories, and Virtual Providers. Some of the properties you can view in the SAP

NetWeaver Administrator are purely informative, that is, you cannot edit them.

The read-only property Defining Components for all JMS resources is defined as a separate tab in the Details section. It contains a table with all applications,

services, and libraries defined in thejms-resources.xml of a particular JMS resource. Using this p roperty you can find which applications, services, and

libraries use a specific JMS resource. If the JMS resource is created programmatically in the jms-resources.xml, or in the SAP NetWeaver Administrator, that

is this resource is not deployed by any application, library, or service, the Defining Components property is empty.

In the Showfield, select JMS Resources to display the details related to the JMS connection factories and JMS destinations, Queues and Topics. The properties

that are related to durable subscribers are in the Details section and are available only for Topics.

application to refer to the Queue, or

the Topic. Later on, this name is used

in JNDI lookups.

Destination ID - JMS Topic, JMS Queue The ID of the destination.

Destination Type JMS Top ic , JMS Queue This property shows whether the JMS

resource is a Queue, or a Topic.

Set Limit to Delivery Attempts Count true JMS Topic, JMS Queue This property limits the number of

delivery attempts and points out if the

undeliverable messages have to be

moved to a dead message queue.

Refer also to Maximum

DeliveryAttempts.

Configuration Property Name Default Value Description

Instance ID - The unique ID of the instance to which the JMS

Virtual Provider belongs.

Instance Name The name of the instance to which the JMS Virtual

Provider belongs.

Clean Up Service Sleep Interval (milliseconds) 600000 The time interval in milliseconds after which the

Cleanup Service is triggered. The Cleanup Service

is responsible for deleting the obsolete JMS

messages from the database - these are the

expired messages and the already acknowledged

messages.

Client Memory Size (bytes) 104857600 This is the total amount of memory a JMS client can

occupy. The implication of increasing this is that

the JMS client will occupy more memory, and thus

might affect the p erformance of other components

and applications.

Destinations Count - The current number of destinations of the JMS

Virtual Provider.

DataSource Name The name of the Data Source this Virtual Provider

is us ing for accessing its persistent store. An

empty value indicates that the default (system)

Data Source will be used. If your app lication uses

database p ersistency and has its own Data

Source, you may consider configuring the same

(application) Data Source to be used by the Virtual

Provider of the application. More information:

Configuring Transaction-Related JMS Virtual

Provider Properties

Running Mode GLOBAL This property determines the clustering behavior of

this JMS Virtual Provider. There are two available

options GLOBAL and LOCAL. More information:

JMS Clustering and Failover

Client Consumer Buffer Size (bytes) 102400 This is the amount of memory a JMS consumer can

use for its message buffer (to pre-fetch messages

from the server), that is, this is the size of the client-

side in-memory message cache per consumer.

The minimum recommended value is the size ofthe largest expected message. Values lower than

that may lead to suboptimal performance.

Cache Size Limit 52428800 The maximum size (in bytes) of the server-side

message cache per JMS Virtual Provider. The

cache is shared among all destinations belonging

to this Virtual Provider.
