DB2 Flowable database creation fails

Hello,

I’m trying to use a DB2 z/os datasource for the flowable tables.
When starting up the spring-boot application I get this error:

ERROR o.f.e.i.d.ProcessDbSchemaManager - problem during schema create, statement alter table ACT_RU_EXECUTION
add constraint ACT_FK_EXE_PROCINST
foreign key (PROC_INST_ID_)
references ACT_RU_EXECUTION (ID_)
com.ibm.db2.jcc.am.SqlSyntaxErrorException: THE DELETE RULE MUST BE CASCADE OR NO ACTION. SQLCODE=-633, SQLSTATE=42915, DRIVER=4.22.29

Any idea how to fix this?

Kind regards,
B;

Looks like starting a second time fixed the issue.
So this can be ignored
