SYMPTOM(s):
SYSTEM ERROR: Unexpected extent switch note (766)
SYSTEM ERROR: End of last note read is at file offset 0 (1048)
The 766 messages can be seen in the database log of the primary database.
The 1048 messages are displayed when attempting to roll forward against the second database.
CAUSE:
The minimum granularity of time for After Imaging to track is one second of time.
If multiple after image control functions occur within the same second of time a single extent switch note may be put into an AI file.
The most likely after image control functions that would cause this problem is too many aimage new commands given in one second of time (this is uncommon).
Another possibility although rare is potential by random chance.
If an aimage new command is given at the same moment when the current busy AI file is tagged as full then functionally two aimage switch notes will be generated, one by you and one by the engine.
The presence of the extent switch note as the only note in the file is unexpected and will cause the roll forward process to generate the 1048 error.
This may effectively end the capability of after imaging to successfully roll forward.
FIX:
1) Roll Forward the next after image in sequence
There may be several AI files which have no notes in them so you may need to roll forward several of the next AI files in sequence of their creation.
