HSetReplication (Function)

In french: HGèreRéplication

Not available with these kinds of connection

Temporarily disables (or re-enables) the replication. Replication can be a log-based replication or a universal replication.

The replication between HFSQL data files is automatically managed.

When the replication is "disabled", you have the ability to access the HFSQL Classic data files without storing the information required by the replication. Then, the replication management must be restored.

Caution: The use of this function is reserved to experienced programmers. We do not advise you to temporarily disable the management of replication and perform modifications on the data files. Indeed, problems may occur during the synchronization.

Remark: The replication is not available when accessing a database via Remote access.

Only the universal replication is available.

Remark: From version 19, HFSQL is the new name of HyperFileSQL.

Versions 21 and later

This function is now available in Universal Windows 10 App mode.

New in version 21

Example

// Disables the log-based replication
HSetReplication(False)
// Add a value that will not be replicated
HAdd(Customer)
// Re-enables the log-based replication
HSetReplication(True)

// Enables the universal replication
HSetReplication(rplReplicationUniversal)

Syntax

Managing log-based replication between HFSQL databases Hide the details

<Result> = HSetReplication(<Management mode>)

<Result>: Boolean

True if the replication was managed before the call to HSetReplication,
False if the replication was not managed before the call to HSetReplication.

<Management mode>: Boolean

False to temporarily disable the management of replication,
True to re-enable the management of replication.

Managing log-based replication (between HFSQL databases) or universal replication Hide the details

<Result> = HSetReplication(<Management mode>)

<Result>: Integer constant

Former management mode of replication (before the modification):
rplReplicationDisabled The replication was not managed before the call to HSetReplication.
rplReplicationUniversal The replication performed before the call to HSetReplication was a universal replication (between HFSQL data files and data files handled by a Native Access for example).
Remark: the rplReplicationHeterogeneous constant can be used for backward compatibility with the earlier versions.
rplReplicationLogged Log-based replication between HFSQL data files was managed before the call to HSetReplication.

<Management mode>: Integer constant

New management mode to use:
rplReplicationDisabled Used to temporarily disable the management of replication.
rplReplicationUniversal Used to perform a universal replication (between a HFSQL database and an Oracle database for example).
Remark: the rplReplicationHeterogeneous constant can be used for backward compatibility with the earlier versions.
rplReplicationLogged Allows you to perform a log-based replication between HFSQL data files (uses the HFSQL data files with logs).

Remarks

The log process is disabled when the replication is disabled. The log process can be re-enabled by HSetLog.
