Re: [Exist-open] java heap memory setting

[Dave F. <dav...@gm...>]

We have a running instance of eXist on that same version of Java, and have
successfully allocated up to 8192 Mb (8 Gb) to it. The two major
differences are that 1) Our kernel version is 3.2 instead of 2.6 and 2) our
eXist version is 2.0. Neither of those *should* make a difference since the
memory allocation is handled by Java directly. It is entirely possible
however that the wrapper may be "capping" the values before passing them to
java, although if that were the case I would be mystified as to the reason
why.

One thing worth trying as a test would be to use the startup.sh script
instead of the wrapper script to kick off eXist. When you run
./bin/startup.sh under the eXist directory, the memory allocations settings
are read in via the eXist-settings.sh file in the ./bin/functions.d
directory. Look for this line in that script:

*JAVA_OPTIONS="-Xms128m -Xmx512m -Dfile.encoding=UTF-8";*

...and change the options to the ones you want. Then run startup.sh and see
if the memory allocations reflect the values you set them to.
