Checkpoint Options Dialog Box

Getting there

Use checkpoint options to determine the frequency with which the DATABridge Client commits (saves) updates from Enterprise Server for a particular data source.

The options are as follows:

Checkpoint every quiet point

When selected, the DATABridge Client commits updates at every quiet point, (that is, when there are no transactions in progress). This makes the updates visible in the client database sooner, but incurs additional overhead updating audit locations and committing changes.

 

Client may not change this

Prevents the Client from overriding the previous setting.

 

Allow checkpoints during Long Transactions

When selected, the DATABridge Client commits updates even if transactions are in progress.

 

Client may not change this

Prevents the Client from overriding the previous setting.

Checkpoint at the first quiet point after every

Enterprise Server commits a transaction group at the first quiet point after any one of the values is satisfied. A value of 0 indicates the parameter is disabled.

Enter default, minimum, and maximum values for one or more of the following:

 

Audit blocks

Number of audit blocks processed since the last commit as indicated by the Audit Block Serial Number (ABSN).

 

Updates

Number of creates, deletes, or modifies since the last commit.

 

Transactions

Number of completed transactions since the last commit.

 

Seconds

Number of seconds elapsed since the last commit. This indicates the time that elapses during replication (not the time that elapsed when the updates originally took place on the host system).

Note: If the Client specifies a value outside the permitted range, Enterprise Server will adjust the value to fall within the permitted range. If no value is specified, the default values are used.
