Thank you.
The default of one hour starts with JDK 6.0 (Mustang) but the reference you
gave me allows the setting of this value for any JDK using the Java command
line option of -Dsun.rmi.dgc.server.gcInterval=3600000 for 1 hour. The
reference document for this is located at
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6200091.
You might want to also add to your documentation something else that has
change in regard to RMI defaults. Starting with JDK 1.3.1 SR7 and JDK
1.4.2 the RMI connection pooling is turned OFF by default. In order to
turn this on you need to add the Java command line option of
-Dsun.rmi.transport.tcp.connectionPool=true.

Please respond to Re: How to disable system.gc()
"JCS Users List" calls every 60 seconds
<[EMAIL PROTECTED]
a.apache.org>
I cannot find any call to System.gc in the src/java
directory. I don't think this is the cause. What is
the symptom, you see gc every 60 seconds? That's an
RMI default setting:
"Default GC interval lengthed to one hour (6200091)
In previous releases, the maximum interval between
garbage collections of the local heap enforced by the
RMI implementation (while there are live remote
references or exported remote objects), which is
controlled by the system properties
sun.rmi.dgc.client.gcInterval and
sun.rmi.dgc.server.gcInterval, was one minute by
default. The default interval is now one hour, to
better accommodate applications with large heap sizes
without special configuration."
