When rs_marker is executed, RepAgent processes it so that Replication Server synchronizes subscription materialization cycles and warm standby applications.
rs_marker is executed with one varchar(255) parameter named @rs_api. RepAgent passes the parameter to the Replication Server in a distribute command with the following syntax:
distribute command_tags param_string
For example, if a client executes rs_marker with the following command:
rs_marker @rs_api='0x1234567'
The Adaptive Server RepAgent submits the following command to the Replication Server:
distribute command_tags 0x1234567
Notice that the @rs_api parameter is not in quotes.
