jobserver increase memory

hi,
i want to allocate more memory for one job, which is run on TAC, so i tried to add JVM parameter,
but it didn't work, i can't allocate more than 1024M...
i changed the tomcat configuration (JAVA_OPTS="-Xms256M-Xmx20480M"), it works, i can see in tomcat server status that the max memory is now 18205.50 MB.
But i think that i have to change some parameter on jobserver configuration, how
can i do this ?

regards,
John

Hi John
Welcome to Talend Community!
What'is the volume of your machine's memory?
The value of xmx cannot exceed the RAM.

Hi John
If you want to allocate more memory for one job, you can modify it in TAC->Job Conductor->JVM parameters as the following image.
There is no need to change configuration of Job Server.

Hi
I use the tool jvisualvm to monitor the JVM parameters for one Talend job.
In my local machine, I can increase the value of XMX larger that 1024M.

This is a really useful component.  Excuse my ignorance but what is the output telling me?
tMemoryMonitor_1: using 2347MB/3217MB (max=3641MB/64%) (processors=2)
<Name of the component>: <current memory use>/<?> (<max memory use allowed>) (<number of processors>)
The value after the "/" what is that?
