Real-time Data/Registry Replication

The file replication function of ClusterReplica Standard 2.0 is among the most powerful and efficient in its class. Besides handling all types of files, including Windows IIS web service and web page files and dynamically generated registry files, ClusterReplica Standard 2.0 replicates files in real time even when the file is open and being used.

With successful installation, some default values of memory space allocation and timing arrangement for data replication operation are set as recommended values for best performance.

 Users, however, still have the power to change these values to best fit their system environment. This flexibility promises the highest product efficiency and user satisfaction.

Following lists the areas users can manipulate to their advantage and needs:

1. Minimum/Maximum virtual memory usage - the virtual memory allocated here is for the ClusterReplica data replication’s internal processes’ use. However, too much memory used by this one application may hinder performance of other applications. So, balanced setting is recommended.
   
2. Replication Version-point - the values set in this section are related to how often a new batch of data is transported from the Primary station to the Secondary station.
1. Regular version-point timeout - this value indicates that data transport for non-database files takes place every four seconds.
2. Max forced version-point queue - this is the number of forced version-point to be queued. The forced version-point is an action taken by ClusterReplica to break a data stream for data replication at the end of  the pre-set version-point timeout period.
   
3. Temporary workspace path - this location is where ClusterReplica stores temporary files during operation. If large database files are to be replicated and report mode is activated, a large space for this temporary workspace may be needed. Users can change the location to a different drive for this purpose.
   
4. Temporary registry file path – this location is for local data replication configuration. Dynamically generated registry files will be copied into this location and can be restored when recovery is needed. Click button Action in the menu bar and select Restore Local Registry to recover registry files.
