Good morning,

We currently have Cascade installed using 32-bit Java but would like to implement the 64-bit. Can we get specific step-by-step instructions on how to start using the 64-bit Java with Cascade 7.0.5

Which Java do we download?
Where do we get it?
How do we start using it?

Thank you,
Joshua Ellis

    Hi Joshua,

    We actually started providing 64-bit installers with our 7.2+ release which you can find here. So, you could download the latest release of Cascade (64-bit), install it to a new location, then configure it to point to your existing database.

    If you are looking to stay on 7.0.5, you'll need to download and install JRE 1.6 (64-bit) and then configure Cascade to use that JRE. On Windows machines, you'll need to perform an additional step which includes downloading the 64-bit version of Tomcat and then copying a handful of files over into the Cascade installation. Then, you'll need to modify the Windows service to use JRE 1.6 as well.

    I would highly recommend going with one of our 64-bit installers, but if you do wish to stay on 7.0.5 let me know and I can provide more details steps.

    Thank you for the incredible response time!

    We are using a Windows machine and have decided to stay on version 7.0.5 for the moment; there are several major projects in progress we don't want to add extra risk to.

    May we request detailed step-by-step instructions to turn over to support staff at the state data center?

    Thank you sir,
    Joshua Ellis

    Not a problem! Here are the steps you'll need to take (make sure Cascade is stopped):

    Step 1: Install a 64-bit JVM

    • Download the Windows x64 JRE (Java 6) from the Oracle web site here
    • Install the Windows x64 JRE

    Step 2: Download 64-bit Tomcat

    • Download the 64-bit Windows zip file for Tomcat from here
    • Unzip the file into a temporary location

    Step 3: Copy service files

    • Copy the following files from the extracted Tomcat archive:

      • bin\tcnative-1.dll
      • bin\tomcat6.exe
      • bin\tomcat6w.exe
    • Paste all 3 files from above into your Cascade Server installation directory under tomcat\bin (be sure to overwrite the existing files!)

    Step 4: Configure the service

    • Navigate to the \tomcat\bin directory inside the Cascade Server installation folder and find the file named tomcat6w.exe
    • Make a copy of this file and rename it cascadew.exe
    • Double-click the file cascadew.exe
    • In the configuration UI click on the Java tab
    • In the Java Virtual Machine field, select jvm.dll from the 64-bit JRE that was installed in Step 1 (located in bin/server in the Java installation directory)
    • In the Java Options field, add the following value on a new line: -XX:MaxPermSize=192m
    • Enter a value for the Initial memory pool field (preferably 2000M or more)
    • Enter a value for the Maximum memory pool field (preferably 2000M or more...must be larger than initial memory pool)
    • Click Apply, then click OK

    These instructions were exactly what was needed at our Data Center. Thank you very much.
