This is a forum entry to report a possible bug in JBPM 3.1.4, Oracle (not sure about others) DB scripts. System: JBossAS 4.0.5 GA + jBPM 3.1.4 GA + RHEL 4 + Oracle 10g. The column JBPM_VARIABLEINSTANCE.STRINGVALUE_ is slated as VARCHAR2(255 char) while JBPM_LOG.OLDSTRINGVALUE_ and JBPM.NEWSTRINGVALUE_ are slated as VARCHAR2(4000). These two values should be a match between each other. FIX: Change the DB script for JBPM_VARIABLEINSTANCE, field STRINGVALUE_, from VARCHAR2(255 char) to VARCHAR2(4000 char).
