com.sleepycat.db.SecondaryDatabase

primary database must already be open. SecondaryKeyCreator keyCreator; // Your key creator implementation. SecondaryConfig secConfig = new SecondaryConfig(); secConfig.setAllowCreate(true); secConfig.setSortedDuplicates(true); secConfig.setKeyCreator(keyCreator); SecondaryDatabase newDb = env.openSecondaryDatabase(transaction, "myDatabaseName", primaryDb, secConfig)

If a primary database is to be associated with one or more secondary databases, it may not be configured for duplicates.

Note that the associations between primary and secondary databases are not stored persistently. Whenever a primary database is opened for write access by the application, the appropriate associated secondary databases should also be opened by the application. This is necessary to ensure data integrity when changes are made to the primary database.

        mySecConfig.setKeyCreator(keyCreator);


        // Now open it
        try {
            itemnameindexdb = databasesHome + "/" + itemnameindexdb;
            itemNameIndexDb = new SecondaryDatabase(itemnameindexdb,
                                                    null,
                                                    inventoryDb,
                                                    mySecConfig);
        } catch(FileNotFoundException fnfe) {
            System.err.println("MyDbs: " + fnfe.toString());

         * doNotCreate is true and the database does not exist, we silently
         * ignore the DatabaseNotFoundException and return null.  When
         * getSecondaryIndex is subsequently called, the secondary database
         * will be created and populated from the primary -- a bulk load.
