I know I have TX enqueues, with a mode = 4. From all my research, I bet it is ITL related. I know I can increase initrans and/or freelists, but the issue is what object(s) is this needed most? I understand in v9, you can use segment level statistics. In my version (8.1.7.4 - HP-UX), I do not know how to narrow this down to an object. I bet if I can work this out, the enqueues will go away. Any ideas on how to narrow this down? I have very heavy OLTP system.
