STRMNUMMISMTCH2, Stream nnnn exists on the source instance file but is unknown on the receiver instance
MUPIP Error: Issued by a Source Server on a supplementary instance when it detects a non-Supplementary stream number nnnn (which can be any value from 1 through 15) exists on the source instance but not on the receiving instance. This indicates the two instances are not in sync at least with respect to stream nnnn and so replication cannot proceed.
Action: Reinitialize the receiving instance from a backup of the source instance and restart replication between the two instances.
