Starting a rout once on start and then always at 3am

[dermoritz <ta...@hotmail.com>]

I have a route using jdbc component to fetch some data from db.

so my idea is:
from("quartz:<cron expression for 3am>").to(jdbc:...)

My problem is that "fireNow" seems only to work for simple timer. Is there
an easy way to fire the route once at start (after first run this route
triggers start of other routes.)?

<bean id="date" class="org.apache.camel.routepolicy.quartz.SimpleDate"/>
 
 <bean id="startPolicy"
class="org.apache.camel.routepolicy.quartz.SimpleScheduledRoutePolicy">
     <property name="routeStartTime" value="time"/>          
 </bean>
        
 <camelContext id="testRouteContext"
xmlns="http://camel.apache.org/schema/spring">
     <route id="testRoute" autoStartup="false" routePolicyRef="startPolicy">
         <from uri="seda:foo?concurrentConsumers=20"/>
         <to uri="mock:result"/>
     </route>
 </camelContext>
</route>

In from uri u can give a dummy timer to start ur route.

thanks in meanwhile i took the 2 routes way.

it's working fine and fits well.

but i 'll think about your three route approach.

you can split your original route into three ones like that:

from("direct:process")
     .to(jdbc)
     .whatever;

from("timer:myTimer? repeatCount=1")
     .to("direct:process");

from("quarz:cron")
     .to("direct:process");

that way the direct:process route gets triggerd by the timer and the 
quarz routes.

[dermoritz <ta...@hotmail.com>]

you mean i should create 2 routes:

from(timer:repeateOnce).to(jdbc)
and
from(timer:cronExpr).to(jdbc)
?

thats not very beautiful but a good option.

What about (came to mind in meanwhile):

from(timer:cronExpr).to(direct:startNow).to(jdbc:)

does this work?

Hi,

you can use a second route with a timer and set the timer property 
repeatCount to 1, so the timer will only fire once when the route is 
started. Have a look here:
