While on the subject of CATALINA_OPTS. In 9.0.46, the catalina.sh script
displays these when it runs. I have several options in the CATALINA_OPTS,
which makes this pretty long.
I don't remember it being this way in the past. I would imagine that if this
was changed to be like this, there was a good reason, but it makes my startup
process look broken. Would having this go to the catalina.out file be a good
solution? Or it is critical for others that it is output to stdout?
If this is critical, should JAVA_OPTS also be displayed to stdout?
-----
(
In the setenv.sh file, we use enough options that we use line continuation to
make the file more readable which makes the CATALINA_OPTS line less readable
because of the whitespace.
-Xms128M \
-Xmx512M \

Thanks! That clears things up a lot. I think my admins got confused and did
both because there are some instructions that say to add these in JAVA_OPTS,
but those instructions are specifically for Windows servers (we're on RHEL).
Thanks everyone for all the info and help.
