9207.0. "How to tune per-process max size limit?" by TPOMC2::DAVIDHSIEH () Mon Mar 17 1997 18:54

    HI,
    
    Does the DUNIX can limit per-process working set (allocation space)? I
    have see the NOTE 1607, it seems can satisfy our requirement.
    
    Could someone can explain the following attributes meaning and usage:
    
        The system limits are in /etc/sysconfigtab
        proc:
            max-per-proc-datasize
            max-per-proc-address-space
        vm:
            vm-maxvas
    
    Appreciate any hints about those attribute affect and how to tune.

Hi

Have you read the system tuning guide that is part of the
OS docs?

Have you altavista or comet searched for this?
9207.2How to I/O subsystem?TPOMC1::DAVIDHSIEHThu Mar 27 1997 20:3514
    Hi,
    
    Thanks for your reply. I have read the Tuning Guide but lack the
    description in B-15 about those proc attributes.
    
    We have done the proc/mem tuning, it is very useful. We have another
    problem is the user runs ERGO sar software, it still affects other
    process very much. 
    
    How can I limit the ERGO sar process to prevent others from low
    response. And any hints to tune the I/O subsystem, the ERGO sar does
    the very hard I/O.
    
    Regards,
