[jboss-user] [Management, JMX/JBoss] - How do you run multiple schedules (mbeans)? What am I doing
I need the ability to run multiple schedules (scheduled mbeans, both able to run at the
same exact time) on Jboss 4.0.5/JDK5. I reviewed the Scheduler javadocs
(http://docs.jboss.org/jbossas/javadoc/4.0.5/varia/org/jboss/varia/schedul...)
and it specifically states:anonymous wrote : Scheduler Instance to allow clients to run
this as a scheduling service for any Schedulable instances.
| ATTENTION: The scheduler instance only allows to run one schedule at a time. Therefore
when you want to run two schedules create to instances with this MBean. Suggested Object
Name for the MBean are:
| :service=Scheduler,schedule=
| This way you should not run into a name conflict.
I'm almost positive I've done what is recommended to run multiple schedules. Here
is what the jmx-console says (among other things) about my scheduled mbeans I've
created in a deployed SAR:anonymous wrote : name=MQLoaderA
| name=MQLoaderB
| name=MQLoaderC
| schedule=MQLoaderA,service=Scheduler
| schedule=MQLoaderB,service=Scheduler
| schedule=MQLoaderC,service=Scheduler
| service=ScheduleManager
| service=Timer
Here is what my jboss-service.xml looks like for these mbeans:<mbean
code="com.titanium.business.scheduler.Loader"
name=":name=MQLoaderA"></mbean>
|
| <mbean code="org.jboss.varia.scheduler.Scheduler"
name=":service=Scheduler,schedule=MQLoaderA">
| <depends>jboss:service=ScheduleManager</depends>
|
<depends>jboss.j2ee:service=EJB,jndiName=titanium/MQLoaderMap</depends>
| <attribute name="StartAtStartup">true</attribute>
| <attribute
name="SchedulableMBean">:name=MQLoaderA</attribute>
| <attribute name="SchedulableMBeanMethod">doIt()</attribute>
| <attribute name="InitialStartDate">1/1/08 1:00
am</attribute>
| <attribute name="SchedulePeriod">3600000</attribute>
| <attribute name="InitialRepetitions">-1</attribute>
| <attribute name="FixedRate">true</attribute>
| </mbean>
|
| <mbean code="com.titanium.business.scheduler.Loader"
name=":name=MQLoaderB"></mbean>
|
| <mbean code="org.jboss.varia.scheduler.Scheduler"
name=":service=Scheduler,schedule=MQLoaderB">
| <depends>jboss:service=ScheduleManager</depends>
|
<depends>jboss.j2ee:service=EJB,jndiName=titanium/MQLoaderMap</depends>
| <attribute name="StartAtStartup">true</attribute>
| <attribute
name="SchedulableMBean">:name=MQLoaderB</attribute>
| <attribute name="SchedulableMBeanMethod">doIt()</attribute>
| <attribute name="InitialStartDate">1/1/08 1:00
am</attribute>
| <attribute name="SchedulePeriod">3600000</attribute>
| <attribute name="InitialRepetitions">-1</attribute>
| <attribute name="FixedRate">true</attribute>
| </mbean>
|
| <mbean code="com.titanium.business.scheduler.Loader"
name=":name=MQLoaderC"></mbean>
|
| <mbean code="org.jboss.varia.scheduler.Scheduler"
name=":service=Scheduler,schedule=MQLoaderC">
| <depends>jboss:service=ScheduleManager</depends>
|
<depends>jboss.j2ee:service=EJB,jndiName=titanium/MQLoaderMap</depends>
| <attribute name="StartAtStartup">true</attribute>
| <attribute
name="SchedulableMBean">:name=MQLoaderC</attribute>
| <attribute name="SchedulableMBeanMethod">doIt()</attribute>
| <attribute name="InitialStartDate">1/1/08 1:00
am</attribute>
| <attribute name="SchedulePeriod">3600000</attribute>
| <attribute name="InitialRepetitions">-1</attribute>
| <attribute name="FixedRate">true</attribute>
| </mbean>
These MBeans are configured to fire at the same exact time (on the hour) but they
don't; they run one after the other. Did I not name the schedules correctly like the
javadocs suggested? This worked perfectly on JBoss 3.2.6 so I'm a little confused. I
appreciate any help with this. Thanks!
