[jboss-jira] [JBoss JIRA] (AS7-3809) Limit of open file descriptors missing in standalone.sh/domain.sh in AS7

[Stuart Douglas (JIRA)]

Stuart Douglas resolved AS7-3809.
---------------------------------

    Resolution: Rejected


This caused some problems in our internal tests, and after some discussion we decided that we were better off without it. We decided that a better approach is just to make sure that we have adequate documentation on the issue, as in most cases the user is going to need to use sudo to adjust the system wide limit anyway.

> In AS6 run.sh script included an option to raise the limit of open file descriptors. In AS7, where run.sh was replaced by standalone.sh/domain.sh, MAX_FD variable still exists, but it's not used.
> If you decide to include this functionality in AS7, it would be great if the flow of the script would be changed, so it doesn't immediately stop when MAX_FD could not be set, but it tries with a lower value. Something like:
> {noformat}
> STEP_VALUE=50
> i=${MAX_FD}
> while [ ${i} -gt 0 ]; do
>     if ulimit -n ${i} 2> /dev/null 1>&2; then
>         percent=`expr ${i} \* 100 \/ ${MAX_FD}`
>         echo "Open files limit set to ${i} (${percent}% value of desired ${MAX_FD})."
>         exit 0
>     else
>         i=`expr ${i} - ${STEP_VALUE}`
>     fi
> done
> {noformat}
