    Unanswered: Updating ulimit for db2 fenced user

    We have been getting memory related errors on the diag and I see IBM is suggesting to increase 'data' value on the ulimit for fenced user.
    I am about to request my Unix admin to update this, but I am not sure if we need to recycle the db2 instance. We have feepfenced=YES and I want to know if it is possible to resolve this without an outage.

    Error message in diag -
    OSERR : ENOMEM (12) "Not enough space"
    MESSAGE : Private memory and/or virtual address space exhausted, or data ulimit

    Referred to this link -

    Thanks in advance.

    If that DB2-instance has any db2fmp process(es) running then those would have to be stopped. A clean way to do that is to bounce the instance, but there may be alternatives - check with IBM
