hi,
Our oracle8.1.7 runs on HP-UX 11i with HP disk-array xp-1024. The
disk array is raid-0.
there are about 3 million accout mainteined in the DB which has
accouting data input into the db. There are three snapshots on four
tables of the DB. The refreshing interval is 5min. the four tables
which are snapshoted mainteins the most part of information in DB.
The max session number of DB is 600, and the peak connection number
recorded is 571.
we experience DB performance problem in past months. And, there
happened three times of DB crash.
I'm new to this area. Is there anyone would like to share
knowledge and exprience with such problem ? ( e.g. where should I
start ? what should be the key point of analysis? is there any mustread
on DB optimization? )
any word will be highly appreciated.
Joe
ps. the following is tracefile of DB crash , and disk io on DB server.
