Re: Unprotected Storage

["Al Barsa" <barsa@xxxxxxxxxxxxxxxxxxx>]

The first history of unprotected storage being an issue was when checksum
was brought into the architecture at CPF Release 8.0 of the System/38.
Checksum was parity protection, like RAID-5, but done at the software
level.  When you had a disk failure, you still failed, but the disk still
had to be replaced, and then the system re-ipled, so you had the effect of
abnormal end of CPF.

I've asked this once before, never got an answer - perhaps some new blood
in
the list (or someone who may have passed-by it in the past) can shed some
light on this.

On a WRKSYSSTS screen you have the "current unprotect used" and "maximum
unprotect" - I equate this to essentially being like virtual memory on a
PC.

What I don't know is an easy way to see WHAT is using it.  I do know that
runaway ODBC jobs can start chewing it up - you kill the job, the usage
goes
down.  I don't know how to see any other use.

Is there an easy command or way to see what is consuming this unprotect
memory, since it does eat DASD just as an object would.  Thanks in advance
for the assistance.
