Websphe JVM maximum memory allocated

Ahounguio Jean Francois (20218) | asked Aug 20 '16, 3:25 a.m.
Hi Community,
I have deployed recently RNDG with WAS on a single server with 32 GB RAM.
I used an evaluating topology because this is for only 10 concurrent users.
I have allocated 12 GB to the JVM machine and i want to extend this to 20 GB at least.
Is there a maximum memory to be allocated ?

If you're talking about the JVM heap size (-Xmx), it is not always the larger the better. Start with a smaller size (12GB should be plenty for quite a long while) and increase it only when you get OutOfMemory in the Java heap area. The general guidance is set the upper limit to 3/4 of the physical memory size, which is 24GB in your case.
