The syscdrack_txn Table
The syscdrack_txn table contains information about the acknowledgment queue.
When the target database server applies transactions, it sends an acknowledgment to the source database server. When the source database server receives the acknowledgment, it can then delete those transactions from its send queue. The acknowledgment queue is an in-memory only queue. That is, it is a volatile queue that is lost if the database server is stopped.
