to increase MaxPermSize memory in Java by command line

Question

Could you please explain me how to increase this PermSpace size. I am using Gate application and loading huge amount of data and large number of plugins and unfortunately after

Answer 1

-XX:MaxPermSize=256m

Maybe combined with 32 bit addresses for objects, instead of 64 bits

-XX:+UseCompressedOops

Enables the use of compressed pointers (object references represented as 32 bit offsets instead of 64-bit pointers) for optimized 64-bit performance with Java heap sizes less than 32gb.

See VM Options.

Also check that String internalization does not occur. XML introduced in the past a String.intern() to save space, but then Perm space grows. So maybe check your XML settings.
