**** SOLVED - see last entry ****
in some Integration Server server.log the following message is written:
java.sql.SQLIntegrityConstraintViolationException: [sag-cjdbc42-0011][Oracle JDBC Driver][Oracle]ORA-00001: violation de contrainte unique (PRT.PRTPROCLOCK_PK)
PRT.PRTPROCLOCK_PK indicates a problem with a primary key. But this table is not used on purpose.
- The application, does not include a PRT process, at all.
Is there a valid reason - why this table is used?
