Java VM parameters on Solaris

To set java parameters:

# which java
this will show the path for current java, eg. /usr/bin/java, normally this is a symbolic link.

To cleanup old java, just remove this link.

Then, create a symbolic link to your new java command where ever is:

# ln -s {new java path} /usr/bin/java (example only, depend on "which java" command output).

you copy answer from @arnold@ to my previous question by mistake?

That was my answer even though I did not ge any pionts.

I'm very sorry, I'll give you points on this question.
But please answer on this question, not for previous.
Sorry again.

Don't know can set RAM to Java. One way can allocate RAM to Oracle is to set them in/etc/system file as recommemded by Oracle doc.
eg.
set shmsys:shminfo_shmmax=#######

Maybe experts for Solaris can help?

Oracle and java handle the memory on their own.

Oracle 11 just requires an amount of memory and it will manage all the others settings.

A dev database with less than 100'000 rows per table can be handled in a 2-4 GB ram

Java requires a little more tuning, depending on the application it need to manage and the version. Generally starting setting -Xmx will be enough

If you start the java app from command line just add -Xmx1g
Es. java -Xmx1g main
For application servers and other complex java app there should be a file to set the java executable parameters

To have more info answer the following questions:

I have single instance, but the question is that when I try to set -Xmx and -Xms on Solaris version of Netbeans it doesn't accept any arrangements, and I have to leave it empty.
I want to set for Java 30% - 8g, but I can't, something block this arrangement.

thank you for the good link
