NetXMS Support Forum

hi tomaskir,

your guess was correct. The memory was unset.
After a search on the web,  i made the change on CATALINA_OPTS="-Xms2048M -Xmx2048M".
this change should be in setenv.sh file (create it if doesn't exist) as [export CATALINA_OPTS="-Xms2048M -Xmx2048M"] in the same directory as catalina.sh wich will load it at the start. After  a tomcat restart i was able to open MIB Explorer on Web interface.

thanks again and have a nice day 

sorry but i got http 404 not found, it seems that ubuntu repositroy does not install manager app auto so i have to resolve this issues and i will return to the forum tomorow

thanks for you help.

i have tried with "-Djava.awt.headless=true -Xms2048M -Xmx2048M" and with your suggestion but i cannot open the MIB Explorer on Web UI [chrome  and FireFox browser].
it shows processing for some times and we got nothing however in the windows console app it work without any problem.
it's a fresh install did i forget something to intall ?

please help

thanks for your reply,

okay i understood the idea ! My tomcat version is 8 and his default JAVA_OPTS is "-Djava.awt.headless=true -Xms128M" but i have some questions.

what's the difference between Xms and Xmx options ?
how to optimize such parameters, known that my os is ubuntu server 14 with 8 Gb RAM ?

finally should i use "-Djava.awt.headless=true -Xms1024M -Xmx1024M"

thanks again.

Hi Victor,

Can you give us more details about -Xms and -Xmx options  and how/where can we change it ?
