DAX fallbacks
Hi,
could you explain what DAX fallbacks mean in detail and how to avoid them? Or is it ok to have fallbacks?
Unfortunately googling does not help...
MANpage says: fallbacks == Number of commands completed by the software, which DAX could not complete
OK, but why and what does it mean for the DB?
Running RAC on M7 with InMemory:
1st node=DAX commands 35.608.411 with 18 fallbacks
2nd node=DAX commands 63.563.607 with 2.656.188 fallbacks
Is it just a bad day for the second node? Any ideas how I could dig deeper at OS or DB level?
Thanks in advance and regards
- Martin
