Steps what I did

1. Start the kie execution server

2. Start the jbpm process which has human task

3. Stop kie execution server

4. Again start kie execution server

5. Try to claim the human task from the process which I did it in step 2

Here I won't get any human task present not even the process instance.

What I want is even kie execution server restart this process instance state should persist so whenever I restart the server I should get all the processes which are InProgress.

Can anyone help me out?

Thank You...

configure db properly as by default it uses in memory db that is lost when you restart server.

I tried to check some documents on configuring the db but I dent found any except the one which you have written http://mswiderski.blogspot.in/2015/10/installing-kie-server-and-workbench-on.html In this blog there is a command

-Dorg.kie.server.persistence.ds=java:jboss/datasources/jbpmDS

-Dorg.kie.server.persistence.dialect=org.hibernate.dialect.MySQL5Dialec

Is this the one which you are talking about or this is nowhere related to my question?

If this is not the one, can you suggest any example or any document

Thank you.

Hi,

I created separate JNDI in wildfly, this is what log I got

2017-07-17 11:41:53,789 INFO [org.jboss.as.connector.subsystems.datasources] (MSC service thread 1-7) WFLYJCA0001: Bound data source [java:jboss/jdbc/MySQLDS]

But still, I am not able to persist the processes in my DB.

I attached log file,

I think I am missing something which I am not able to figure out.

This is how I am starting the server

standalone.sh --server-config=standalone-full.xml -Dorg.kie.server.id=wildfly-kieserver -Dorg.kie.server.location=http://localhost:8081/kie-server/services/rest/server -Dorg.kie.server.persistence.ds=java:jboss/jdbc/MySQLDS -Dorg.kie.server.persistence.dialect=org.hibernate.dialect.MySQL5Dialect

Can anyone help me on it?

I even tried with this

standalone.sh --server-config=standalone-full.xml -Dorg.kie.server.id=wildfly-kieserver -Dorg.kie.server.location=http://localhost:8081/kie-server/services/rest/server -Dorg.kie.server.persistence.ds=java:jboss/datasources/MySQLDS -Dorg.kie.server.persistence.dialect=org.hibernate.dialect.MySQL5Dialect -Dorg.kie.server.persistence.tm=bitronix.tm.resource.jdbc.lrc.LrcXADataSource

nothing helped...

Can anyone figure out what I am doing wrong?

Thank you...

you have removed default data source which is still needed by the app server - java.jboss.datasources.ExampleDS

do add it back next to you MySQL data source and set only these system properties

-Dorg.kie.server.persistence.ds=java:jboss/jdbc/MySQLDS -Dorg.kie.server.persistence.dialect=org.hibernate.dialect.MySQL5Dialect

This is how I created in standalone-ful.xml

<connection-url>jdbc:mysql://localhost:3306/rps_am</connection-url>

<driver>mysql</driver>

<user-name>root</user-name>

</security>

</datasource>

<xa-datasource-class>com.mysql.jdbc.Driver</xa-datasource-class>

</driver>

</drivers>

<connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE</connection-url>

<user-name>sa</user-name>

</security>

</datasource>

<xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>

</driver>

</drivers>

</datasources>

</subsystem>

Is it the correct one I have configured or anything mess?
