Libarary QPFRDATA too big on the system

Hi Guys,

We have this library QPFRDATA on our iSeries(i5/OS), which is occupying 10% of our disk space. Its size has grown to almost 231 GB.

we were wondering if we can use the command :

DLTPFRDTA MBR(*SELECT) LIB(QPFRDATA) JOBD(QPFRJOBD)

to lower the size of the system.

Our QPFRADJ(Performance adjustment) parameter is set to 0(0=No adjustment).

Is that Ok to do or is it going to affect our system in any way? I would guess not, but still want to confirm.

Pls advice.

Thanks

Abhi
