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.
|
| |
|
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

|
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.
|
| |
|
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.
|
| |
|
Is it possible to modify the existing Publication/Subscription?
|
| |
Yes, keeping the end user requirement in mind, we have added this feature in

in/from Publication. Subsequent subscription can be updated also.
|
| |
|
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).
|
| |
|
Is there any option provided for Debugging in Replicator (OS)?
