<Source>.InitSubscriber (Function)
In french: <Source>.InitAbonné
AjaxNot available
HFSQLHFSQL Client/ServerAvailable only with these kinds of connection
Initializes the range of automatic identifiers for the description file of subscriber replica (".RPL" extension). This function can be used with log-based replication only.
The range of automatic identifiers is initialized:
<Source>.InitSubscriber must be called only when the data files are installed on the subscriber.
Caution: The data files must be opened before <Source>.InitSubscriber is used.
Example
// Initialize range of auto IDs for the Customer data file
Customer.InitSubscriber("C:\DATA\Replic\ParisSubscriber.RPL")
Syntax
<Result> = <Source>.InitSubscriber(<Subscriber Replica>)
<Result>: Boolean
  • True if the initialization was performed,
  • False if an error occurred. HErrorInfo is used to identify the error.
<Source>: Type corresponding to the specified source
Name of HFSQL data file to use.
<Subscriber Replica>: Character string
Name and full path of subscriber replica. This parameter can correspond to a UNC path.
Remarks

Range of identifiers

The automatic identifiers for the files of subscriber replicas are using a range of identifiers that differs from the one used by the file of master replica and by the other files of subscriber replicas.
This range of automatic identifiers is written in the header of each data file (".FIC" extension).
This range is initialized:
The range of identifiers is returned by MinAutoID and MaxAutoID.
For more details, see the consequences of implementing the replication.

Replication and log process

If <Source>.InitSubscriber is used, the location of logs and operation tables must also be initialized (<Source>.ChangeLogDir, LogDirectory and OperationLogDirectory).
Reminder: Log-based replication uses logs and operation tables of data files. Log-based replication does not work if the location of the logs and operation tables is invalid.
