Examples of com.sleepycat.je.Environment.openSecondaryDatabase()

• com.sleepycat.je.Environment.openSecondaryDatabase()
  Opens and optionally creates a SecondaryDatabase.

  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.

  @param txn For a transactional database, an explicit transaction may bespecified, or null may be specified to use auto-commit. For a non-transactional database, null must be specified. @param databaseName The name of the database. @param primaryDatabase the primary database with which the secondarydatabase will be associated. The primary database must not be configured for duplicates. @param dbConfig The secondary database attributes. If null, defaultattributes are used. @return Database handle. @throws DatabaseExistsException if the database already exists and the{@code DatabaseConfig ExclusiveCreate} parameter is true. @throws DatabaseNotFoundException if the database does not exist and the{@code DatabaseConfig AllowCreate} parameter is false. @throws OperationFailureException if one of the Read Operation Failures occurs. If the database does not exist and the {@link DatabaseConfig#setAllowCreate AllowCreate} parameter is true, then oneof the Write Operation Failures may also occur. @throws EnvironmentFailureException if an unexpected, internal orenvironment-wide failure occurs. @throws IllegalStateException if this handle or the underlyingenvironment has been closed. @throws IllegalArgumentException if an invalid parameter is specified,for example, an invalid {@code SecondaryConfig} property. @throws IllegalStateException if DatabaseConfig properties are changedand there are other open handles for this database.
