QMPGDATA
Good morning. My name is Eduardo San Nicolas and I have a problem of occupation in my iSeries (9406-550 in V5.4) I am not currently collecting performance data and to free up space I thought QMPGDATA delete the library. My question is if I run the command CLRLIB QMPGDATA can cause a problem in the system.

Thank you very much in advance and best regards.

    I'd recommend using ENDPFRCOL (better safe than sorry) then DLTPFRCOL.

    Thanks for the reply Splat. The problem is that now I'm not collecting performance data and if I try to delete performance data with DLTPFRDTA (I have’t on my system DLTPFRCOL) tells me that I haven´t to clear performance data. Still QMPGDATA library occupies 20 GB.

    ...tells me that I haven´t to clear performance data. Can you say that again, please? The sentence doesn't make sense. There must be a word missing. Tom

    Sorry! I meant that the system tells me that I have no performance data to clear.

    If you're certain you don't want to keep Performance Tools, go to the Work with Licensed Programs menu (LICPGM) and delete it. I'd recommend a full backup before you do so though.

    ...the system tells me that I have no performance data to clear. In that case, please show us exactly how you ran the DLTPFRDTA command. What parameters did you use? Tom

    I use the command DLTPFRDTA LIB(QMPGDATA) and the system displays many members erasable. Before erasing it to free up space, whit the command DSPPFRDTA LIB(QMPGDATA) I try to view its contents and all that tells me there is nothing to show. Really deleting them will free space? Thanks!

    It sounds like the members are empty, but still extant. Deleting those will certainly free up space, but whether it will be sufficient to your purposes I can't say.

    Really deleting them will free space? Without looking at the file and member descriptions, it's impossible to be sure if enough space will be recovered to be noticed. But yes, at least some space will indeed be returned for use by other processes. If no data exists in the members, I don't think there is any reason to keep them around no matter how much space is involved. Tom
