When a RepAgent starts, it uses a locater to determine where to begin scanning the database log. The locater for a database log is stored in the rs_locater table in the Replication Server System Database (RSSD) of the Replication Server that controls the database.
The locater points to a record on a page in the database log. If the truncation point for the database is turned off, you or Adaptive Server may truncate the page the locater points to, invalidating the locater. When the locater is invalid, the RepAgent writes error message 9215 to the Adaptive Server error log.
To recover, reset the locater to 0x0. This directs the RepAgent to begin scanning the log from the truncation point.
