BEGIN px_login(:1, :2, :3, :4); ENDlooked like the first two were the batch jobs and the 3rd was the web login
first 2 looked really bad , ran 6/min, 300K logicalread each.
By the way this is a 3rd party app, we can not access the codes, but we may make the improvement with the init file. please advise.
