The character set used in communication with the Replication Server.
"" (empty string)
Any valid character set supported by the Java VM on the Mirror Replication Agent host machine.
Sybase recommends that you:
Configure the primary and standby data servers and the Replication Server to all use the same character set
Use the default rs_charset value "" (empty string)
When you initialize the Mirror Replication Agent instance, the value of the pds_charset parameter is automatically set to match the primary Adaptive Server default character set, which is identified by the Adaptive Server default character set id configuration parameter.
Using the default rs_charset value "" with a valid pds_charset value is equivalent to setting both parameters to the same value, and it has a distinct benefit; it reduces the opportunity for human error (such as entering an incorrect value for the rs_charset parameter).
The value of the rs_charset parameter must match (or be compatible with) the Replication Server default character set, which is identified by the Replication Server RS_charset configuration parameter.
If you specify a valid character set for the value of the rs_charset parameter, the Mirror Replication Agent instance sends replicated transaction data from the primary database to the Replication Server in that character set.
If you do not specify a valid character set name for the value of the rs_charset parameter (including the default rs_charset value ""), the Mirror Replication Agent instance sends replicated transaction data to the Replication Server using either:
The primary database character set, specified in the Mirror Replication Agent pds_charset parameter, if the pds_charset value is a valid character set name, or
The system default character set, specified by the Java VM file.encoding system property on the Mirror Replication Agent host machine, if the pds_charset value is not a valid character set name (including the default pds_charset value "").
If the values of the rs_charset and pds_charset parameters are valid, but not the same value, Mirror Replication Agent converts the replicated transaction data from the primary database character set (pds_charset) to the Replication Server character set (rs_charset) before sending it to the Replication Server.
