Upgrading JVM for DST Changes

[djaeger]

I am curring running Windows 2003 with Coldfusion 6.1 Updater. I'm using the
TechNotes d2ab4470 and 2d547983 to upgrade my JVM to version 1.4.2_11. We are
currently on 1.4.2.

When downloading the update, do I need to download
j2re-1_4_2_11-windows-i586-p.exe or j2sdk-1_4_2_11-windows-i586-p.exe?

Also, how can I just "update" my current java.home directory which is
c:/jrun4/runtime/jre instead of installing the upgrade to a whole different
directory and changeing pointers to the new directory?

Any help is appreciated.

I'm about to do the same update for several servers at my site. I
would recommend that you

1. Install the 1.4.2_11 JDK/SDK into a specific folder like: c:\java
\1.4.2_11\.
1a. (I have about 5 different version of java installed in the c:
\java folder myself.)
2. Backup your jvm.config file.
3. Modify your jvm.config file to point to the new java path.

This way, you can easily back out of the JVM update (by restoring your
original jvm.config file) if you need to (which I doubt you will).

You'll need the j2sdk (I'd recommend getting _13 because it addresses a
critical security vulnerability in anything older). There is a JAVA_HOME
system variable you can set. But you'll need to go into your Coldfusion admin
and change the path there. It'll look something like this:

c:/java/j2sdk1.4.2_13/jre

Can I just update my current version in the directory c:\jrun4\runtime\jre or do I need to install it into a whole different directory and change the java.home line in the jvm.config file?
