Common DB for activiti-app and activiti-rest?

Jump to solution

Hi,

I'm relatively new to activiti. For the past few days I've been reading parts of the user guide (mostly the REST API part) and researched the different web apps that come with activiti 6 (activiti-app, activiti-rest, activiti-admin). I noticed that activiti-app and activiti-rest work with different databases.

How can I set them to read and write from/to the same database? Preferably PostgreSQL that runs on an Ubuntu VM.

Your help is highly appreciated,

Aviran

You can configure DB setting by editing the following properties file.

  • activiti-6.0.0/wars/activiti-app/WEB-INF/classes/META-INF/activiti-app/activiti-app.properties
  • activiti-6.0.0/wars/activiti-rest/WEB-INF/classes/db.properties

I'm having the same issue. I currently haven't configured the activiti-app/activiti-rest to use anything other than the in memory DB that the war files are deployed with. Have you configured them to use a different DB yet?

I configured both files as you suggested. It works for activiti-app (thank you!), but activiti-rest fails to load for some reason. I can see the following exception in the log:

Do you use H2 Database? If so, this error is may be specification of H2 database, according to the following link.

Concurrency issues with H2 file mode · Issue #748 · spark-jobserver/spark-jobserver · GitHub 

Could you use real database like Postgresql?

You're right, I was using H2. After switching to PostgreSQL everything works as expected.

So I have updated these to files to use MySQL. Activiti-app works. I can see it saving data in the DB. 

activiti-rest fails to start. My db.properties file is 

db=activiti6
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/activiti6?characterEncoding=UTF-8
jdbc.username=root
jdbc.password=

my activiti-app.properties file (the DB section anyway) is 

datasource.driver=com.mysql.jdbc.Driver
datasource.url=jdbc:mysql://localhost:3306/activiti6?characterEncoding=UTF-8

datasource.username=root
datasource.password=
hibernate.dialect=org.hibernate.dialect.MySQLDialect

Do I have something incorrect here?
