I want to start mule quartz with condition..
For ex: In mule peroperties file I put one flag=on.If that flag is on then and only then Scheduler will be start.If that flag is off then schedule will be not called.
How can I do this in mule?
Please help
Mule is wired up with Spring so the tricks/features you can use to make some beans conditional should work for Mule too.
I would try the following:
Extract the flow definition where the Quartz endpoint is started into quartz-config-on.xml
Create an empty Mule XML config named quartz-config-off.xml
In your main Mule XML config, use: <import resource="quartz-config-${quartz.flag}.xml"/> where quartz.flag is a property that is either on or off
I used a work around to achieve this kind of behavior. I defined a Quartz connector where the cron expression to trigger it is loaded from a property file.
If you put the expression to something that won't trigger until 2099 it's almost equivalent to a disabled cron.
<quartz:inbound-endpoint cronExpression="${cron1.expression}"
jobName="scheduler1" doc:name="Scheduler 1">
<quartz:event-generator-job>
<quartz:payload>${cron1.request};${cron1.trade.date.offset}/quartz:payload>
</quartz:event-generator-job>
</quartz:inbound-endpoint>
And the property file:
#Scheduler 1 settings
cron1.expression = 3 14 15 9 2 ? 2099
cron1.request = none
cron1.trade.date.offset = 0

i would like to route my http:request to my main ( or secondary ) error handler in Anypoint Studio 7
i does not seem to have a clear way of doing it.
And the documentation does not have guideline for this specific case.
in my case is necessary, i need to know and send a signal to another service and communicate the error response, like: connection_timeout
You can catch the errors you want using an error-handler in your flow where you are executing the http:request. if you do not catch the error, it will bubble up to the calling flow and so on. If no error-handler is configured, the default mule one will be used which just logs the message basically.
In Mule 4 you can catch all errors in your flow like so:
<flow name="retrieveMatchingOrders">
<http:request config-ref="customersConfig" path="/customer">
</http:request>
<error-handler>
<on-error-continue>
<!-- error handling logic -->
</on-error-continue>
</error-handler>
</flow>
An on-error-continue will execute and use the result of the execution, as the result of its owner (as if the owner had actually completed the execution successfully). Any transactions at this point would be committed as well
So in there, you can set the payload to your desired message to be returned etc.
There also an on-error-propogate handler and a try scope, more information on those are available here: https://docs.mulesoft.com/mule-runtime/4.1/intro-error-handlers
All errors thrown in Mule contain meta-data including a TYPE. If you need to catch specific HTTP Errors you can configure your error-handler like so:
<error-handler>
<on-error-continue type="HTTP:TIMEOUT">
<!-- error handling logic -->
</on-error-continue>
</error-handler>
Here is a list of all specific HTTP: errors thrown by the HTTP module:
HTTP:UNSUPPORTED_MEDIA_TYPE
HTTP:CONNECTIVITY
HTTP:INTERNAL_SERVER_ERROR
HTTP:METHOD_NOT_ALLOWED
HTTP:NOT_ACCEPTABLE
HTTP:TOO_MANY_REQUESTS
HTTP:SERVICE_UNAVAILABLE
HTTP:CLIENT_SECURITY
HTTP:FORBIDDEN
HTTP:UNAUTHORIZED
HTTP:RETRY_EXHAUSTED
HTTP:NOT_FOUND
HTTP:BAD_REQUEST
HTTP:PARSING
HTTP:TIMEOUT
HTTP:SECURITY
Each module's documentation should contain all specific error types thrown by that module. Here is the HTTP one example:
https://docs.mulesoft.com/connectors/http/http-documentation#throws
And here is a full list of core error types you can catch like EXPRESSION for example:

I am using Redis Data Set as a data source in my JMeter tests. I have configured the redis key with a value I retrieve from a JSR223 sampler.
Below are my test samplers.
in the bove JSR223 sampler I retrieve a previous value ${operator} and put in to properties.
Then in the next sampler ,
I reuse the value as ${__P(operator)}.
The issue with this is ,it doesn't look like JSR233 sampler is running before jp#gc RedisDataset. so the script fails like below.
Stop Thread seen for thread XXXXXX 1-1, reason: org.apache.jorphan.util.JMeterStopThreadException: End of Redis data detected, thread will exit
If I run the script once commenting the Redis data set sampler, and run on a second run with enabling it, the value can be seen, as the value have been stored in the Jmeter memory, this way it was evident that Redis data set runs before JSR223 sampler. I can not move JSR 233 sampler out of the test fragment to a much higher level as I need to run it within the test fragment.
Is there a location which defines these order of executions with Redis samplers ?
Or is there a way to define the order in Jmeter so that JSR223 will run before Redis sampler?
===================================
UPDATE 1
After #Dmitri-t s reply, I have updated the project as follows .
and
As per Execution Order chapter of JMeter User Manual:
0. Configuration elements
1. Pre-Processors
2. Timers
3. Sampler
4. Post-Processors (unless SampleResult is null)
5. Assertions (unless SampleResult is null)
6. Listeners (unless SampleResult is null)
Redis Data Set is a Configuration Element therefore it will be executed prior to anything else.
The only way you can make this operator property dynamic is overriding it via -J command-line argument like:
jmeter -Joperator=something -n -t test.jmx -l result.jtl
I got That working in the following way
TestPlan
|--Thread group
|--Module Controller -1
| |--CSV Data Set Config - to load operator name(this is going to be reused in other thread groups)
|--Module Controller -2
|--JSR233 Sampler - To read a second level file with ${operator} in its name
|--For Each Controller - to read through the second level file
| |--User Defined Variables - to split the line from the second level file in to variables
|--HTTP Request - Action sampler with ${operator} and other variables

I am as a client inserting/updating/fetching values to/from back-end DB via JCA files creating business service and making the call. I am facing problem while performing insert/update call as for all the request i will be getting success response irrespective of the DB getting added/updated. If there is a way to confirm like these many rows got updated after insert/update DB then it confirms like operation is successful.
Below is the simple JCA file to update the DB, can you please let me know what extra configuration i need to do to get the number of rows get updated..!
<adapter-config name="RetrieveSecCustRelationship" adapter="Database Adapter" wsdlLocation="RetrieveSecCustRelationship.wsdl" xmlns="http://platform.integration.oracle/blocks/adapter/fw/metadata">
<connection-factory location="eis/DB/Database" UIConnectionName="Database" adapterRef=""/>
<endpoint-interaction portType="RetrieveSecCustRelationship_ptt" operation="RetrieveSecCustRelationship">
<interaction-spec className="oracle.tip.adapter.db.DBPureSQLInteractionSpec">
<property name="SqlString" value=**"update CUSTOMER_INSTALLED_PRODUCT set CUSTOMER_ID=? where CUSTOMER_ID=?"**/>
<property name="GetActiveUnitOfWork" value="false"/>
<property name="QueryTimeout" value="6"/>
</interaction-spec>

Thanks & Regards
I'm afraid you will need to wrap it in PL/SQL and then extend that PL/SQL so number of affected rows is being returned. Then you could extract this value from response variable with XPath.
I am trying to set a scheduler in order to set a cron expression.
<camel:endpoint id="sqlEndpoint" uri="sql:${sqlQuery}?scheduler=spring&scheduler.cron=0+6+8+*+*&dataSourceRef=veloxityDS&useIterator=false"/>
But when I run this as a consumer, this exception occured:
org.apache.camel.FailedToCreateConsumerException: Failed to create
Consumer for endpoint: Endpoint[sql://$select * from
dual?dataSourceRef=veloxityDS&scheduler=spring&scheduler.cron=0+6+8++&useIterator=false].
Reason: There are 1 scheduler parameters that couldn't be set on the
endpoint. Check the uri if the parameters are spelt correctly and that
they are properties of the endpoint. Unknown parameters=[{cron=0 6 8 *
*}]
Any ideas?
The endpoint you are trying to create is using parameters that don't exist. There is a full list of parameters at: http://camel.apache.org/sql-component.html
If you want your SQL procedure to run on a time interval you can either use a quartz endpoint, a polling consumer, or a route scheduler depending on your needs.
http://camel.apache.org/polling-consumer.html
http://camel.apache.org/quartz2.html
http://camel.apache.org/cronscheduledroutepolicy.html
Current parameter issues on your endpoint:
scheduler - not a supported parameter
scheduler.cron - not a supported parameter
dataSourceRef - deprecated.
Your scheduling alternatives leveraging only the sql endpoint are:
consumer.delay
consumer.initialDelay
consumer.useFixedDelay
maxMessagesPerPoll
ENV: camunda 7.4, BPMN 2.0
Given a process, which can be started by multiple start message events.
is it possible to query process instances started by specific messages identified by message name?
if yes, how?
if no, why?
if not at the moment, when?
Some APIs like IncidentMessages?
That is no out-of-the-box feature but should be easy to build by using process variables.
The basic steps are:
1. Implement an execution listener that sets the message name as a variable:
public class MessageStartEventListener implements ExecutionListener {
public void notify(DelegateExecution execution) throws Exception {
execution.setVariable("startMessage", "MessageName");
}
}
Note that via DelegateExecution#getBpmnModelElementInstance you can access the BPMN element that the listener is attached to, so you could determine the message name dynamically.
2. Declare the execution listener at the message start events:
<process id="executionListenersProcess">
<startEvent id="theStart">
<extensionElements>
<camunda:executionListener
event="start" class="org.camunda.bpm.examples.bpmn.executionlistener.MessageStartEventListener" />
</extensionElements>
<messageEventDefinition ... />
</startEvent>
...
</process>
Note that with a BPMN parse listener, you can add such a listener programmatically to every message start event in every process definition. See this example.
3. Make a process instance query filtering by that variable
RuntimeService runtimeService = processEngine.getRuntimeService();
List<ProcessInstance> matchingInstances = runtimeService
.createProcessInstanceQuery()
.variableValueEquals("startMessage", "MessageName")
.list();
