Hi experts,

I'm switching Activiti application from in-memory database to Oracle. Scripts,, were successfully executed and all tables were created in the database. Application starts up fine and gets initialized without any problems. However, I get the following error when I try running one of my Activiti workflows.

Hibernate: select hibernate_sequence.nextval from dual
[2016-03-09 10:02:35] [W] [SqlExceptionHelper.logExceptions:144] SQL Error: 2289, SQLState: 42000
[2016-03-09 10:02:35] [E] [SqlExceptionHelper.logExceptions:146] ORA-02289: sequence does not exist

My workflow takes a couple of variables that are persisted in JPA repository. I understand that the error is returned because Hibernate can't find the sequence for generating IDs for my variables.

My question is whether I need to create this sequence myself or it's created by one of the scripts that I missed? Thanks a lot in advance!

By the way, I have the following settings to ensure that DDL scripts are not executed on start-up
