Sets the current replicator position. When using this option, the -seqno, -epoch, -event-id, and -source-id options must be specified to set the corresponding values in the replicator.

If a configuration exists, and you do not specify the -reset then an error will be displayed, for example:

shell> dsctl set -seqno 214 -epoch 0 -event-id "mysql-bin.000011:0000000000072857;8196" -source-id "db1"
Cannot set position unless existing position data is removed - reset first

Either issue the reset as a seperate option, or include in the single command, for example:

shell> dsctl reset
Service "alpha" datasource "global" catalog information cleared

shell> dsctl set -seqno 214 -epoch 0 -event-id "mysql-bin.000011:0000000000072857;8196" -source-id "db1"
Service "alpha" datasource "global" position was set to: seqno=214 epoch_number=0 eventid=mysql-bin.000011:0000000000072857;8196 source_id=db1

Or:

shell> dsctl set -seqno 214 -epoch 0 -event-id "mysql-bin.000011:0000000000072857;8196" -source-id "db1" -reset
Service "alpha" datasource "global" catalog information cleared
Service "alpha" datasource "global" position was set to: seqno=214 epoch_number=0 eventid=mysql-bin.000011:0000000000072857;8196 source_id=db1
