Universal assisted replication: specific features
 No disponible con este tipo de conexión
Specific features of this version In this version, the specific features of the assisted universal replication are as follows: - Managing the automatic data modification.
- Replication between HFSQL databases: Automatic data modification is only available for universal replication between HFSQL databases.
To manage automatic data modification during replication, you must specify this in the ReplicEdit tool: in the replication description, in the "Advanced" tab, option "Propagar las modificaciones automáticas de los archivos de datos de la base de datos maestra a las bases de datos esclavas (disponible solo si ambas bases de datos utilizan HFSQL Classic y/o Client/Server).".
Caution: - For existing replications, it is necessary to recreate a replication (as well as the subscribers) to implement this mechanism.
- This mechanism does not work if a unique key is added or deleted. In this case, the automatic modification must be performed in the same way as for databases in different formats.
- Replication between databases of different formats: There is no automation mechanism for automatic data modification in this version. You must:
- synchronize as many subscribers as possible before the automatic data modification.
- perform the automatic data modification on the master files.
- perform the automatic data modification on the subscriber files.
- synchronize the subscribers.
- Replication management for User Groupware files.
The files of the User Groupware are not automatically managed by the assisted universal replication. A copy of the files of the User Groupware must be managed "manually" on the local computer. - Direct replication
The .WER file must be necessarily deployed beside the executable file (even for a programmed replication). The.WER file cannot be included in a WINDEV library (.WDL file). - Assisted universal replication and WINDEV Mobile
ReplicSynchro Mobile version is not supplied in this version. An assisted universal replication must be performed by using the WLanguage programming functions. For more details, see Assisted Universal Replication programmatically. - Assisted universal replication and WEBDEV
With WEBDEV, an assisted universal replication must be performed by using the WLanguage programming functions. For more details, see Assisted Universal Replication programmatically. - Parameters for accessing the master files
The ReplicAdmin tool cannot be used to modify master file access parameters: it is necessary to perform an installation using the installation creation wizard, and to update the application.
Therefore, a replication cannot be deployed directly on a computer without using an application. - Volume of data
Caution: universal replication may encounter difficulties with large data volumes. The main limiting factor is the size of the key used to identify the records. For example, an integer key (or automatic identifier) will allow you to replicate more records than a string key.
Furthermore, we recommend that you replicate a sub-set of records by using the filtering features of the assisted replication. Indeed, it is the volume of replicated data and not the total volume of data that must be taken into account.
