Hi all
Maybe someone can assist me with this one. A while back I requested some information relating to the MySQL innodb buffer pool size that seems to fill up rather frequently. The buffer pool is currently set to 3Gb , and it takes about 2-3 weeks after a restart to fill up. Someone replied and stated that this is preferred to be running at 100% usage as it means that it is running optimally. However, the oracle guys in our office disagrees with this and want to know the following: . If the innodb buffer pool is at 100% full, how will we know when it needs more buffers o i.e. let's say the database starts getting very busy and needs more buffers, how will we know that it requires this if the buffer pool usage is already at 100%. I am fairly new to database administration so no luck in answering them on this so I would appreciate the assistance. Regards Machiel
