Summary: Out Of Memory Error

Initial Comment:
I am attempting to write and read fairly large messages
to and from a OpenJms message queue. I can read and
write an endless number of messages that are
1,256,000 bytes long. When I double the size, I can
write and read approximately a dozen messages before
getting the following error message:

Error [server - 9] - Failed to process message due to out
of memory error java.lang.OutOfMemoryError.

if I increase the size of the message to for example
6,000,000 bytes, I get the above error on the first
message.

I have tried this on two machines, one with a half
megabyte of memory and one with 2 megabyte of
memory. The results appear to be the same.

This leaves me with two questions. First, how can I
configure OpenJMS to accept larger message sizes?
Second, if I configure OpenJMS to use a database
repository, does this problem go away?

First, don't use the JDBM. Use an RDBMS such as MySQL
instead. The JDBM has proved to be not very reliable and won't
be supported in the 0.7.7 release.

Second, you can increase memory available to the server by
adding a line to your $OPENJMS_HOME/setenv.sh (or .bat)
script e.g:

JAVA_OPTS=-Xmx256m
