Hi Denis

We used to get this a lot with rogue SQL session from PC clients. I wrote a
background utility to watch for disk use increase and send a message to
QSYSOPR if it passed a set threshold. It also checks temporary storage per
job, and CPU per job. You can tweak it to fit your circumstances - code is

Hello all,

We are currently facing a major problem. There is, on one of our systems,
1 or more job that is consuming disk at an alarming rate (the % used goes
up 1 percent every 5 minutes or so). We have thousands of jobs running and
we can not easily pin point the guilty one.

In the past, we got lucky some times (a badly defined SQL that we were
able to spot), and unlucky some others (IPL when the % got to high).

Does anyone can give me hints on how to spot, on the fly, the disk
consumption of a job, be that for Database IO or temporary memory space.

Thanks in advance
