If our change places Oracle in an impossible situation or Oracle deems the change inappropriate in any way, Oracle may simply ignore our suggestion or choose a value that is close to our suggestion and acceptable to Oracle. 6 If you have given the keep and recycle pools a lot of thought, you might notice by messing with the midpoint, you can essentially turn the entire buffer cache into either a keep or recycle pool. 7 If you are curious about using the reason code, you can find plenty of information available online. Just do an Internet search on "oracle buffer busy reason code."
