  • Closed as program error.

Error description

  • When using derby as the scenario database performance can be
    poor with large datasets during data check stage.
    

Local fix

  • Add following property in .odmds file:
    
        <properties>
          <property name="KEY_INDEX" value="app\..+"/>
        </properties>
    
    After adding the property, repository section of .odmds file
    will look like:
    
      <repository multiUser="false" concurrencyMode="exclusive">
        <connection>
          <JDBCDriverClass
    name="org.apache.derby.jdbc.EmbeddedDriver"/>
    
    <JDBCURL>jdbc:derby:directory:$ODM_APP_DIR/odmrepository</JDBCUR
    L>
        </connection>
        <managerClass
    name="ilog.odm.datasvc.persist.derby.IloEmbeddedDerbyRepositoryM
    anagerFactory"/>
        <properties>
          <property name="KEY_INDEX" value="app\..+"/>
        </properties>
      </repository>
    

Problem summary

  • Indexes for tables are not getting created and data check query
    uses an execution plan that relies on indexes. This leads to
    poor performance with large data sets.
    

Problem conclusion

  • Issue has been resolved and fix will be available in ODM
    Enterprise 3.6.0.1.
    

Temporary fix
