How to configure flowable with AS400/DB2

I am trying to configure flowable with as400/db2 and I found a solution to my problem on the activity forum.
Could you try to fix this issue?

Hi,

Is the issue that the databaseTypeMapping is not in the list for the as400/db2 case? What is the exact string value that we should add?

Best regards,

Tijs

Hi,
the exact string from the logfile is ‘DB2 UDB for AS/400’.
And could you tell me when you would lauch a new release?

That doesn’t look like the technical string, it probable needs to be something like DB2/400, see flowable-engine/AbstractEngineConfiguration.java at 859e46a38015211714bdb1e6380797b36b7fa320 · flowable/flowable-engine · GitHub

On workaround for now is to subclass the engine configuration, and add your own mapping to the databaseTypeMappings.
