[jbpm-users] [JBoss jBPM] - Problems with indexes in jbpm.history.hbm.xml

I think there is a problem with the way indexes are defined in hibernate for history tables (jbpm.history.hbm.xml). Example: | <class name="HistoryProcessInstanceImpl" table="JBPM4_HIST_PROCINST"> | <id name="dbid" column="DBID_"> | <generator class="assigned" /> | </id> | | ... | | <set name="details" | cascade="all"> | <key foreign-key="FK_HDETAIL_HPROCI"> | <column name="HPROCI_" index="IDX_HDETAIL_HPROCI" /> | </key> | <one-to-many class="HistoryDetailImpl" /> | </set> | | </class> | If you go down in the file you will find the table for HistoryDetailImpl with the many-to-one definition: | <class name="HistoryDetailImpl" table="JBPM4_HIST_DETAIL"> | ... | | <many-to-one name="historyProcessInstance" | class="HistoryProcessInstanceImpl" | column="HPROCI_" | foreign-key="FK_HDET_HPROCI" | index="IDX_HDET_HPROCI" /> | <property name="historyProcessInstanceIndex" column="HPROCIIDX_" /> | | ... | So there are two name for the same index (on the same column HPROCI_): IDX_HDETAIL_HPROCI (from the inverse one-to-many relation) and IDX_HDET_HPROCI (from the direct many-to-one relation). That causes hbm2ddl tool to create a faulty sql (in the jbpm-4.0 ditribution see db/jbpm.oracle.create.sql): | create index IDX_HDET_HACTI on JBPM4_HIST_DETAIL (HACTI_); | | create index IDX_HDET_HPROCI on JBPM4_HIST_DETAIL (HPROCI_); | | create index IDX_HDETAIL_HACTI on JBPM4_HIST_DETAIL (HACTI_); | | create index IDX_HDETAIL_HVAR on JBPM4_HIST_DETAIL (HVAR_); | | create index IDX_HDETAIL_HTASK on JBPM4_HIST_DETAIL (HTASK_); | | create index IDX_HDETAIL_HPROCI on JBPM4_HIST_DETAIL (HPROCI_); | | create index IDX_HDET_HVAR on JBPM4_HIST_DETAIL (HVAR_); | | create index IDX_HDET_HTASK on JBPM4_HIST_DETAIL (HTASK_); Oracle will throw an error about duplicate index on the same column for columns HACTI_, HVAR_, HTASK_. For whatever reason MySql and HSQLDB work fine with this indexes but oracle has a problem. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4247034#...
