Hi Kevin,
Oops sorry. Yes, I was referring to the heap memory setting we
used for Jakarta EE 8 TCK runs. ( we are yet to run Platform TCK
for Jakarta EE 9).
I cannot find any configurable setting to alter the stack size
(-Xss) within the TCK. We could check if the test run commands in
ts.jte (command.testExecute*) can be made use of, to add the stack
size.
Can you share details of the default stack size that was changed
for IBM run if the change was within the TCK source. It would also
help to know for future reference, which specific tests needed the
change in stack size to run.
Regards,
Alwin Joseph

Thanks,
Alwin.
The options
you
referenced are for the "heap size", not the "stack size".
The scripts you referenced do not seem to be setting the "stack
size" (-Xss), so maybe that's being set outside of these scripts
as
just part of the environment configuration?

Re: [jakartaee-tck-dev] stack size for running the Platform TCK
for Jakarta
EE 9?
Hi Kevin,
For running platform TCK against
glassfish
we change the default memory settings in VI, RI and the TCK only
for ejb30
tests. This configuration change is done from [1] to [2]. The
maximum memory
is increased in the bin/ts.jte for the TCK to Xmx4096m for the
platform
TCK run in CI [2].
[1] https://github.com/eclipse-ee4j/jakartaee-tck/blob/38cb27458e1ace61de3eb767713136c9484d130e/docker/run_jakartaeetck.sh#L251

Hi,
Does anybody know the stack size that is used when running the
Platform
TCK for Jakarta EE 9? Some of you know that we (IBM) have been
hitting
a couple of issue when attempting to run the TCK with HotSpot
(works with
OpenJ9). We've recently discovered that we can get around the
problem
by doubling the default stack size to 2048k (-Xss2048k).
Since everyone's environment might be setup slightly different,
I'm
wondering what our Jakarta EE runs use for the stack size? And,
whether
this is a configurable item that needs to be updated somewhere
in the TCK
configuration? Or, maybe it's already set at a higher value and
our
(IBM) environment was out of sync. Thanks!
