Problem(Abstract) |
IBM® WebSphere® Application Server V5.0 and V5.1 is
installed with embedded messaging (Server & Client). The embedded
messaging feature is a scaled-down version of the full WebSphere MQ 5.3
product and consists of a queue manager for point-to-point messaging and a
broker for publish-subscribe messaging.
Because embedded messaging is not a full installation of the WebSphere MQ
product, some of the capabilities provided with MQ are not available.
After installing embedded messaging, you cannot start the MQ queue manager
or broker independently of WebSphere Application Server .
When embedded messaging is installed on Windows® NT® or Windows 2000, a
Windows service called "WebSphere Embedded Messaging Publish and Subscribe
WAS_nodeName_serverName" is created. Any attempt to start this service
fails with the following error:
Error 1075: The dependency service does not exist or has been
marked for deletion.
In the <MQ home>\Errors directory, the AMQERR001.LOG file shows the
following message:
AMQ7199: The purchased processor allowance is set to -1.
EXPLANATION:
The purchased processor allowance for this installation has been set to
-1 using the MQ setmqcap command.
ACTION:
None.
Different errors are issued when trying to start the embedded queue
manager or broker from the command line, either on Windows or another
platform. |
|
|
|
Cause |
The error is a result of trying to start the broker
process outside of an IBM WebSphere Application Server Java™ Virtual
Machine (JVM) (either an application server or jmsserver). This error
message is logged when you try to start the broker service from the
operating system. |

Resolving the
problem |
When you have a WebSphere Application Server system
installed with embedded messaging rather than the full WebSphere MQ, you
cannot start embedded messaging as a separate service in the Services
panel. When WebSphere Application Server starts, the embedded queue
manager and broker start automatically. Embedded messaging is only used
for JMS applications running in WebSphere Application Server.
If embedded messaging is installed rather than WebSphere MQ, the following
features of MQ are not available:
- MQ Explorer and MQ Services GUIs
- MQ Samples
- MQ SSL Support
If you want to install WebSphere MQ, do not select the embedded
messaging option when installing WebSphere Application Server.
