Examine the exceptions log to determine the transactions that have been skipped.
Skipped transactions are written into the exceptions log. Orphan transactions and transactions logged by sysadmin log_first_tran are also in the exceptions log.
If a replicate database is not receiving updates, the update transactions may have been skipped and written into the exceptions log.
The exception log consists of three tables: rs_exceptshdr, rs_exceptscmd, and rs_systext. The rs_exceptshdr table has one entry for each transaction. The rs_exceptscmd table has one entry for each command (either source or output) of the transaction. The rs_systext table stores the text of the commands. See the Replication Server Reference Manual.
