Oracle Database Error ACFS-05924: Snapshot Duplication Mismatch
Description
This error occurs during the application of an incremental ACFS snapshot duplication stream. It indicates that the base snapshot for the current incremental stream does not align with the last successfully applied snapshot on the target, breaking the continuity of the replication process. This typically happens when the target ACFS file system's state is not what the source expected for the next incremental update.
Error Message
unable to apply the incremental snapshot duplication stream because its starting snapshot does not match the final snapshot used to create the most recently applied snapshot duplication stream
Known Causes
3 known causesTarget File System Out of Sync
The target ACFS file system's state does not match the expected base snapshot for applying the next incremental stream, leading to a break in the replication chain.
Previous Stream Incomplete/Corrupt
The preceding incremental snapshot duplication stream was not fully applied, or its final snapshot metadata is missing or corrupted on the target, preventing a continuous update.
Incorrect Snapshot Sequence
Snapshot duplication streams were generated or applied out of order, or a stream was skipped, resulting in a mismatch between the current stream's base and the target's state.
