Why "25G x2" -> -Xms minimal, -Xmx maximal? 2013/7/4 Tru Huynh > On Thu, Jul 04, 2013 at 09:54:49AM +0200, Rafał Radecki wrote: > > Hi All. > > > > # cat /etc/redhat-release > > CentOS release 6.2 (Final) > you should upgrade to 6.4... > >... > > I have a solr installation which is invoked: > > /usr/bin/java -Xms25g -Xmx25g -DSTOP.PORT=8079 -DSTOP.KEY=mustard > > -Dsolr.solr.home=multicore -jar start.jar > > > > After start/when the java process is running: > > # free -m > > total used free sharedbuffers cached > > Mem: 32093 23975 8118 0189 5736 > > -/+ buffers/cache: 18049 14043 > > Swap: 4095 22 4073 > > > > So the machine has 32GB of RAM, and java process needs 25GB to start. > > When I make a restart the java process dies and in log: > how do you "restart"? are you sure that your java is stopped before > starting it again? > 25G x2 > 32(ram) + 4(swap) until the 1st java instance is actually stopped. > > Tru > -- > Tru Huynh (mirrors, CentOS i386/x86_64 Package Maintenance) > http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xBEFA581B > > ___ > CentOS mailing list > CentOS@centos.org > http://lists.centos.org/mailman/listinfo/centos > > ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Java/Solr - Could not reserve enough space for object heap.
stop/start, I use restart which is stop and start:
start () {
echo -n $"Starting $prog: "
if [ -e /var/lock/subsys/solr ]; then
echo -n $"cannot start solr: solr is already running.";
failure $"cannot start solr: solr already running.";
echo
return 1
fi
cd $SOLR_DIR
daemon $JAVA $JAVA_OPTIONS 2>&1 | /usr/bin/logger -t 'solr' -p info
-- &
RETVAL=$?
echo
[ $RETVAL = 0 ] && touch /var/lock/subsys/solr
return $RETVAL
}
stop () {
echo -n $"Stopping $prog: "
if [ ! -e /var/lock/subsys/solr ]; then
echo -n $"cannot stop solr: solr is not running."
failure $"cannot stop solr: solr is not running."
echo
return 1;
fi
cd $SOLR_DIR
$JAVA $JAVA_OPTIONS_STOP --stop
RETVAL=$?
sleep 2
echo
[ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/solr
return $RETVAL
}
