Hello @Martin11 ,
Agree @SwathiPulagam , besides that I'd like to add:
1- Please make sure if any defined scheduler, scripts, or manual operations to try to stop the task
2- Check if the task 'crash', you may check the later/newer one task log file (if the task restarted automatically), in general if there is a line in the beginning of the new file, looks like:
|[TASK_MANAGER ]I: Task 'xxxxxx' running full load and CDC in resume mode after recoverable error, retry #1
The "retry #n" means the task ever crashed. "N" is the retry number.
3- if the task got error or carshed, maybe there are some clues in Windows Event Viewer, or DB2 log file
4- Try to turn off "Apply changes" and "Store changes" in task setting but keep Full Load ON only , run the task again to see if the error caused by connection issue (timeout, broken, firewall kills a 'too long' connection etc), or only relevant to CDC component "SOURCE_CAPTURE".
5- Turn on TRACE at components of SOURCE_CAPTURE/SOURCE_UNLOAD to get more information. Please turn them on just before the error time, try to avoid too big task log file generated.
Hops this helps.
