About this task
You can use web services to publish events
from any client application capable of being a web service client.
This approach is valuable because web services provide platform and
programming language flexibility.
You can use Web Services Notification to publish an
event message to the common event infrastructure (CEI). CEI is still
used for event filtering and distribution to the actual monitor model
input queues. Hence, Web Services Notification serves
as a simple web services interface in front of CEI.
For information about enabling security, see the
RedBook Web Services Handbook for WebSphere® Application Server 6.1.
For
information about the concepts of Web Services Notification and the features
that are available in WebSphere Application
Server 8.0 to provide
an open standards approach to publish and subscribe messaging, see The developerWorks® Technical
Library.
The configuration scripts are
installed with IBM Business Monitor in
the following directory: monitor_root\scripts.wbm\wsn.
These scripts enable the Web Services Notification service by integrating
with the service integration bus in WebSphere Application
Server. The scripts
also enable specific configuration of resources to emit events through
the service integration bus (SIBus) and CEI to IBM Business Monitor.
To
configure IBM Business Monitor to
use Web Services Notification, complete
the following steps:
- Install and configure the Service Data Objects (SDO) repository
application in WebSphere Application
Server. Because you are using a service integration bus for enabling
web services, you must use SDO as the standard format to store and
retrieve Web Services Description Language (WSDL) definitions. Therefore,
you must create an SDO repository that can be implemented using a
database engine. For instructions, see the related link to the WebSphere Application
Server information
center.
- Copy the files that contain the configuration resources
to a working directory. The files consist of jython
scripts and a properties file as explained in the following table.
Table 1. Contents of the scripts.wbm\wsn directory| File |
Comments |
| configEventWSN.py |
Use this script to set up the necessary Web Services Notification, JMS, SIBus, and
CEI resources. |
| removeEventWSN.py |
Use this script to uninstall the Web Services Notification, JMS, SIBus, and
CEI resources. |
| eventWSN.properties |
This file contains the common resource names
and properties that the two scripts use. |
- Edit the eventWSN.properties file so that it reflects the
properties that are unique to your environment.
Table 2. eventWSN.properties file properties and descriptions| Property |
Description |
| crtCellName = |
The cell name of the WebSphere Application
Server |
| crtNodeName = |
The node name of the WebSphere Application
Server |
| crtServerName = |
The server name of the WebSphere Application
Server |
| host = |
The host where WebSphere Application
Server is installed.
The value, localhost, is valid; you do not have to change that value. |
| wsnPort = |
The WebSphere Application
Server http_transport
port |
| EventServiceMdb = |
This file is located in the EventServiceMdb.ear
file, which is located under the was_root/installedApps directory. For
example, when the monitor toolkit is installed on Integration
Designer 8.0, the EventServerMdb.jar
file is located in profile_root/profile_name/installedApps/cell_name/EventService.ear.
|
- Run the following configEventWSN.py script:
wsadmin -f <path>/configEventWSN.py
-lang jython <path>/eventWSN.properties -profileName <profile>
-conntype=SOAP
where
<path>
is the path where the scripts are located
<profile>
is the name of the profile created for your IBM Business Monitor server.
For example, WBMon01 wsadmin is located in <WAS_root>/bin </profile></path></profile></path></path>
The
following code shows a sample run of the script on an IBM Business Monitor unit
test server that is installed in Integration
Designer:
c:\ibm\WID61\runtimes\bi_v61\bin\wsadmin -f c:\ibm\dev\WSN\scripts\configEventWSN.py
-lang jython c:\ibm\dev\WSN\scripts\eventWSN.properties -profileName WBMonSrv_wps
-conntype=SOAP
- Restart WebSphere Application
Server to
enable the bus definition and the JMS JNDI resources.
Note: If
security is enabled on the IBM Business Monitor server,
but you do not want to use web services security during your initial Web Services Notification client testing,
you can disable security on the CommonEventInfrastructure_Bus service
integration bus.
When the script has run, verify that the
script created the following artifacts successfully:
- A Web Services Notification service
- An endpoint listener
- A Web Services Notification service
point
- A service integration bus destination for messages inbound to
CEI
- A Web Services Notification topic
namespace
- A new JMS topic for messages inbound to CEI
- A new JMS topic that CEI uses to publish to Web Services Notification. This topic is
not used to send events to IBM Business Monitor. Rather,
it can be used to publish events to other Web Services Notification consumers.
- A CEI event group profile that CEI uses to publish to Web Services Notification
- A new JMS activation spec for the message-driven bean inbound
to CEI
- Installed and configured the CEI message-driven bean
- If any of the artifacts in the previous step are not created,
run the removeEventWSN.py script, correct the problem that caused
the script to run unsuccessfully, and try step 4 again.
wsadmin -f <path>/removeEventWSN.py
-lang jython <path>/eventWSN.properties -profileName <profile>
-conntype=SOAP
where
<path> is the
path where the scripts are located
<profile>
is the name of the profile that was created for your IBM Business Monitor server
The
following codes shows a sample run of the script on a IBM Business Monitor unit
test server that is installed in Integration
Designer:
c:\ibm\WID61\runtimes\bi_v61\bin\wsadmin -f c:\ibm\dev\WSN\scripts\removeEventWSN.py
good-lang jython c:\ibm\dev\WSN\scripts\eventWSN.properties -profileName WBMonSrv_wps
-conntype=SOAP
What to do next
Now you can develop and test your
Web Services Notification client to send
events to
IBM Business Monitor.
A useful reference for developing clients is the
Web Services Handbook for WebSphere Application Server 6.1.
To
develop your Web Services Notification client
to send events to IBM Business Monitor, you
can use Business Monitor development toolkit 8.5.7 on Integration
Designer 8.0. You can also
use Business Monitor development toolkit 8.5.7 on Rational® Application
Developer 8.5.x to develop
an application client. However, you must install the requisite level
of Web Services Feature Pack if you decide to use Rational Application
Developer 8.5.x and Business Monitor development toolkit.
