doubt: persistency in pi
I have gone through this blog
There it's written that the messages dont persist for so long(may be for 2 day or 3)
But than going through
confrigration and monitoring home..>adapter engine...>message monitor we can see messages which are processed year ago
I have also heard that during post installation we defined the no of days for whch we want our messages to persist
I am confused between all 3 situations.
how PI handle the situation, in terms of bth singl and dula stack can any body clarify me?
