Where are the runtime timer values stored.

[Arif]

Hello Team,

    I am using default setup that came with jBPM. Meaning I haven't done any configuration changes for timers. I am wondering where are the runtime timer values are stored and if I want to change their runtime values how would I do that without having any negative impact. I thought that they are stored in jbpm database but that is not the case.

By default, jBPM will store the timers in an XML file under the location $JBOSS_HOME/standalone/data/timer-service-data/kie-server.kie-server.EJBTimerScheduler/. While it is possible to edit the initial-date, repeat-interval, next-date values in this file, it is not really advisable to do so - except for development purposes.

Is it possible to change the location of timers from temp data directory to DB ? Any idea what other data like this is stored there ? The reason I am looking for this is because every time I release my changes to prod I have to test them against production data to make sure my new changes works with existing prod data. To achieve this I simply import the prod DB data in to staging server and do my tests. 

Looks like I have to copy the data directory as well but It doesn't look right for me. Any ideas ?

To save timer details in DB you have to modify below tag  from ejb subsystem in standalone-*.xml file:

<timer-service thread-pool-name="default" default-data-store="db-store">
   <data-stores>
     <!--file-data-store name="default-file-store" path="timer-service-data" relative-to="jboss.server.data.dir"/-->  
     <database-data-store name="db-store" datasource-jndi-name="jboss/datasources/bpmSuiteDS" database="mssql"/> <!-- same datasource as used by RHPAM -->
   </data-stores>
</timer-service>

Thanks Abhijit.

   How do I migrate the existing timer values stored in file system to DB, any idea ?

   Also Is there any way I can have both the file and DB data stores and gradually move all the existing timers to DB if timer value migration is not possible ?
