| I have been investigating using jvmstat to get some data to help in
tuning the garbage collection for easerver.
I have read that the jvm instrumentation is on by default from 1.4.2 (I
am currently using 1.4.2_06). When I run easerver from the console I can
use jvmstat (or jstat from j2se5) to get stats from the jvm. When I run
easerver as a service I cant connect to easerver using any of the jvm
tools. I even tried passing in the flag -XX:+UsePerfData, but easerver
seems to ignore it on startup.
Does anybody know if there is somewhere in the code that overrides this
setting?
cheers

| How did you try to pass the VM parameter in?

| Using the 'c.s.j.s.jvm.options' attribute for the sever properties. I
had a look though the serverstart.bat file but there isnt really
anywhere to pass vm options in and you also cant pass in vm options when
installing the service (as far as I can see).
The fact that it works from the console by running just serverstart and
not as a service would indicate to me that it is being overriden as a
service. I think I remember someone from sybase saying there are other
settings like this that get overriden when running as a service.

| That stuff seems to change a lot, so I dont know where it stands these
days. I think you'd be best served by pinging support.
