HRSInit (Function)

In french: HRSInit

Configures a HFSQL server in order for this server to be a master server or a subscriber server for a replication between HFSQL servers. Remark: From version 19, HFSQL is the new name of HyperFileSQL.

Example

HRSInit(Cnt, hrsSubscriber, 1, "pwd", 4996, 5)

Syntax

<Result> = HRSInit(<Connection> , <Server role> , <Server identifier> , <Password> , <Port> , <Priority>)

<Result>: Boolean

True if the configuration was performed,
False otherwise. HErrorInfo is used to identify the error.

<Connection>: Character string (with or without quotes) or Connection variable

Connection to the HFSQL server to configure. This connection corresponds to:
the name of the connection defined in the data model editor or with HDescribeConnection or HOpenConnection.
the name of a Connection variable.

<Server role>: Integer constant

Role of server in the replication:
hrsSubscriber Subscriber computer in the replication between HFSQL servers.
hrsInactive Inactive computer in the replication between HFSQL servers.
hrsMaster Master computer in the replication between HFSQL servers.
hrsMaster + hrsSubscriber Master and subscriber computers in the replication between HFSQL servers (for a bi-directional replication).

<Server identifier>: Integer

Number used to identify the current HFSQL server among all the servers involved in a replication. This identifier must be unique. This identifier must be included between 1 and 32000.

<Password>: Character string (with quotes)

Replication password, used to authenticate the servers between themselves. This password must be used on the other server in the call to HRSAddConfig (i.e. in the ..Password property of hrsConfig).
To use the bidirectional replication, the password must be the same on the two servers.

<Port>: Integer

TCP/IP port number used for the replication between HFSQL servers.

<Priority>: Integer

Priority number of server. During a modification conflict, this number is used if the method for solving the conflict corresponds to a resolution by priority.

Remarks

HRSInit can be used several times on the same server, to change the role of a server in a replication for example.
