TRUNCATE TABLE command does not replicate. You checked and found that the Capture parameter SP_OCT_REPLICATE_DDL is set to 3 which allows Shareplex to replicate supported DDLs as well as TRUNCATE; but the problem persists.
解决办法
As long as the Capture parameter SP_OCT_REPLICATE_DDL is set to 3, Shareplex should replicate all supported DDL and TRUNCATE with one exception. Shareplex does not replicate TRUNCATE executed by SYSTEM, SYS or Shareplex user. If it was issued by any of these users, then this is the expected behavior. Otherwise this needs to be investigated further.
