Daffodil Replicator (OS) transfers information in XML format between the heterogeneous data sources and thus ensures security.

13. Will I have to change my database design to work with Daffodil Replicator (OS)?

There is no need to change the data structure but the tables used in publication must have a primary key.

14. What kind of online help is there to assist me in using Daffodil Replicator (OS)?

Please visit our Bug Repository Section for Daffodil Replicator related bugs or discuss your issues with ourOnline Developers Community

15. What level of ODBC compliance and conformance does Daffodil Replicator (OS) support?

Daffodil Replicator (OS) works only with JDBC.

16. Does Daffodil Replicator (OS) support the star schema and normalized models?

Yes, it does support the star schema and normalized models.

17. Does Daffodil Replicator (OS) take advantage of keys or indexes when it searches? Is it automatic?

Yes, it is an automatic process.

18. What databases are supported by Daffodil Replicator (OS)?

Daffodil Replicator supports Oracle, PostGres, Daffodil DB, Derby, MySQL, Firebird and SQL Server.

19. What do you mean by Publisher?

Publishers are the basic building blocks of a Replicator's synchronization network. Each publisher forms part of a server-client network and is assigned a unique name. The name as well as the other concerned data of each publisher are stored in the publisher database i.e. all relevant information about the publishers, is stored in a database.

20. What do you mean by subscriber?

Subscriber subscribes to Publisher's publications. By definition, a Subscriber must have associated with it a publisher IP address and a port number, and a synchronized data source.

21. Can replication operations be executed automatically i.e. without giving any manual commands?

Yes, it can be done. Daffodil Replicator (OS) uses the concept of scheduling for this purpose. A user can add a replication schedule once and remain free from executing a replication call manually, time and again. Replicator will automatically replicate data on that scheduled time.

22. Does Daffodil Replicator (OS) supports Real time and Periodic replication?

Yes, it does. Daffodil Replicator (OS) uses Scheduling which permits replication in two modes-Real time and Non real time. In Real Time mode of replication, replication process specified in schedule will be performed continuously without any time delay. As soon as a user commits the records after performing any database related operation, it gets reflected on both the sides i.e. Publisher's as well as Subscriber's. Whereas, In Non-Real Time (Periodic) mode of replication, a time period can be assigned by the user for replication process to take place. A schedule can be added and time duration can be specified for replication as yearly, monthly, weekly or hourly basis.

23. Is it possible to modify the existing Publication/Subscription?

Yes, keeping the end user requirement in mind, we have added this feature in the new version of Daffodil Replicator (OS). Now a user can add new tables and drop existing ones in/from Publication. Subsequent subscription can be updated also.

24. Does Daffodil Replicator (OS) include any provision of monitoring the replication process?

Yes, Daffodil Replicator (OS) creates a log file for this purpose. This log file records information like date and time of operation, type of replication used, status of replication operation, statistical data (number of records updated, inserted or deleted).

25. Is there any option provided for Debugging in Replicator (OS)?

Daffodil Replicator (OS) provides the facility of debugging using 'Log4j'. In this file, user can set the logging option as per the requirement. One can set debug level to any one of the following to control the amount of logging-Warn, Error, Fatal, Debug, Info, Off and All.

26. Can a user configure the Replication Home as per his/her requirement?

Yes, it is possible. Replication home is a directory where transaction logs, error log and XML files are created. In the new version of Replicator, a user can configure the Replication Home as per his/her requirement.

27. Does Daffodil Replicator (OS) support special character handling?

Yes, it does. EncodeConfig.ini file is used for this purpose.
