The API_QID_request_interval configuration parameter controls the number of messages LTM for MVS sends to Replication Server before issuing a get truncation command to request a new LTM Locator value from Replication Server.
Issuing a get truncation command forces Replication Server to update rs_locater with the current LTM Locator for the primary database. This prevents Replication Extract from unnecessarily reprocessing transactions upon restart.
See the Replication Server Reference Manual for information about the rs_locater Replication Server system table.
