Stored procedures
The hRSConfig type is used to define the advanced characteristics of a replication between 2 HFSQL servers. The characteristics of this replication can be defined and modified by several WLanguage properties.
Remark: For more details on the declaration of this type of variable and the use of WLanguage properties, see Declaring a variable.
Cnx is Connection
ConfigRéplication1 is hRSConfig
ConfigRéplication1.Server = "atlas.masociete.com:4996"
Add(ConfigRéplication1.File, "Mabase")
Add(ConfigRéplication1.File, "-Mabase\Monfichier.fic")
HRSAddConfig(Cnx, ConfigRéplication1, hrsNoCopy)

Properties specific to the description of hRSConfig variables

The following properties can be used to handle a replication between HFSQL servers:
Property nameType usedEffect
  • True if the replication must be performed in both directions: the replication will be bidirectional.
  • False otherwise (default value): the replication will be unidirectional.
DescriptionCharacter stringDescription of replication.
FileArray of stringsList of elements to replicate.
The elements to replicate can correspond to:
  • a database,
  • a data file,
  • a data file to exclude from the replication. In this case, the name of the file must be prefixed by "-" (minus).
IdentifierIntegerUsed to identify the replication handled.
This property is available in read-only.
Versions 22 and later
New in version 22
IntegerUsed to follow the evolution of the initial copy of replicated elements from the connection server (master server) to the other server (subscriber server) during a copy in background task (HRSAddConfig associated with the hrsCopyBackgroundTask constant).
If this property:
  • is included between 0 and 1000, the replication is currently added.
  • is set to 1000, the replication was added.
  • is not specified, the replication failed to be added.
This property is available in read-only.
PasswordCharacter stringPassword specific to the replication. This password must correspond to the password specified in HRSInit used on the subscriber server.
This property is available in write mode.
SchedulinghScheduling variableReplication period.
If all the members of the hScheduling variable are left empty, it will be a replication in streaming.
ProcedureForModificationConflictResolutionCharacter stringName of the stored procedure to be used if the conflict resolution method (property ConflictResolutionModification) corresponds to the constant hmcrProcedureWithModifiedItems or to the constant hmcrProcedureAllItems.
This stored procedure must return:
  • the opRetry constant to validate the replication of the modification,
  • the opCancel constant to cancel the replication of the modification.
This stored procedure must be found in the replicated database on the subscriber server.
ModificationConflictResolutionInteger constantMethod for solving conflicts:
  • hmcrHigherPriority (default value): During a conflict, only the priority value defined for the server is taken into account. The smaller the priority value defined for the server is, the higher the priority granted to the server will be.
  • hmcrMoreRecent: During a conflict, the more recent element has priority.
    Caution: This method requires a synchronization of the clock on the different servers.
  • hmcrProcedureWithModifiedItems: When a conflict occurs, a stored Procedure is started (defined by the property Procedure ResolutionConflictModification). In this procedure, only the modified items will be accessible.
  • hmcrProcedureAllItems: When a conflict occurs, a stored Procedure is started (defined by the property Procedure ResolutionConflictModification). In this procedure, all the items found in the record will be accessible.
ServerCharacter stringServer toward which the replication will be performed. This server is identified by:
  • its DNS name or its IP address.
  • the replication port (4996 by default).
If the port differs from the default port, the following syntax must be used to specify it: "<Server name>:<Replication port>". This port must correspond to the port specified in HRSInit used on the subscriber server.
Versions 25 and later
New in version 25
  • True to perform a replication in spare mode,
  • False otherwise.
Remark: This Property is incompatible with the Property Bidirectional.
Minimum version required
  • Version 18
