Upgrading JRules to the latest V7.1 fix pack

It is strongly recommended to always run JRules with latest fix pack installed.

Note it is ultimately recommended to migrate to the latest version of the product, V8.0.1, now called Operational Decision Management (ODM) as soon as possible. You can refer to technote Migrating from JRules to ODM for more information.

The sequence to install JRules V7.1 with the latest fix pack is:

1. Download and install JRules V7.1, if you have not already done so.
2. Download and install the latest JRules V7.1 cumulative fix pack (V7.1.1.X)
3. If applicable, deploy or re-deploy the Java EE modules to your server(s).
4. If applicable, install or update the Rule Studio plugins in your existing Eclipse-based IDE.

Ensure that the correct product version for the fix pack is installed, that is, at least V7.1 (7.1.0, 7.1.1 or 7.1.1.X).

Do not uninstall JRules V7.1 before running a fix pack executable. However, if you installed the Rule Solutions for Office module, you must uninstall the existing version of Rule Solutions for Office before running the fix pack installer.

Fix packs are cumulative, therefore you only need to install the latest fix pack on top of your existing V7.1.X.Y installation.

For example, in order to migrate your JRules version from V7.0 to the latest V7.1 fix pack, you must first install JRules V7.1, then install the latest V7.1.1.X fix pack.


Data migration:

• If you are only applying a fix pack on V7.1, the data for all modules remains the same.
• If you are migrating from V7.0.X or an earlier version, you must also complete the migration process of your projects, as described in the section WebSphere ILOG JRules BRMS V7.1 > Migrating of the JRules V7.1 documentation.

Each of the four steps listed above are described below in more detail.


1. Download and install JRules 7.1

If you already have JRules 7.1.1 installed skip this step and proceed to step 2.

To download the JRules V7.1.1 installer go to the V7.1.1 Business Rule Management Systems Download Document page. Browse each section to find the installer that applies to your environment.

For example, to download the JRules core installer, open the WebSphere ILOG JRules V7.1.1 Download Documen t section. On the same page, you can find the Downloading and assembling the product section which provides instructions.

Run the V7.1.1 installers for the modules that you need in the following order, and follow the installation wizard:

1. JRules core or "JRules" that includes Rule Studio and Rule Execution Server
2. Rule Team Server (RTS)
3. Decision Validation Services (DVS)
4. Rule Solution for Office

The JRules core module is required. You must install Rule Team Server (RTS) before installing Decision Validation Services (DVS).

You can only update the components that are installed. For example, if you want to use Rule Team Server (RTS) 7.1.1.X, you must install Rule Team Server (RTS) 7.1.1.

2. Download and install the latest JRules 7.1.1 cumulative fix pack

After you have installed V7.1.1, you can upgrade this version to the latest fix pack. You must first download the fix pack installer for each module to update.

You can find all the fix packs, including the latest, in the WebSphere ILOG JRules BRMS V7.1 Download document.

You must run the fix pack installers in the following order:

1. JRules core or "JRules" (includes Rule Studio and Rule Execution Server)
2. Rule Team Server (RTS)
3. Decision Validation Services (DVS)
4. Rule Solutions for Office
5. Application server bundles

In each wizard, you must indicate the installation directory of your existing JRules V7.1.X.Y installation.

If you are deploying the JRules Java EE modules on an application server other than WebSphere Application Server Community Edition (WAS CE), you must install the corresponding application bundle (step 5).

The application server bundle installers are downloaded along with the module installers.
For example, the WebSphere Application Server bundle installer is jrules_websphere.jar.

For each module that you installed (Rule Execution Server, Rule Team Server, Decision Validation Services), the corresponding Java EE components are then available under <JRulesInstallDir>\<module>\applicationservers\<app server>. You must now deploy or re-deploy them to your server(s).

3. Deploy or re-deploy the Java EE modules to your server(s)

You must deploy or re-deploy the JRules web/Java EE modules to your server(s) following the steps described in the documentation at WebSphere ILOG JRules BRMS V7.1: Java EE add-ons > Installing on <your application server>.

Make sure you have applied the application descriptor changes you need for custom roles and settings, if any, on the up-to-date modules before you deploy them.

4. Install or update the Rule Studio plugins in your existing Eclipse-based IDE

If you chose the run Rule Studio on an Eclipse instance other than the one provided by the JRules installer, you must also follow the steps listed in the documentation at Installing > Installing Rule Studio in Eclipse or Installing > Installing Rule Studio in IBM Eclipse-based products, to install the Rule Studio plugins or apply the latest fix pack.

Notes:

• Rule Studio and all the Java EE modules deployed must run with the same exact version, including the same fix pack level (see technote Installing and using versions of JRules modules that are different from each other).
• The JRules Updater tool is available to guide you through the steps of the above "download and install the latest JRules V7.1.1 cumulative fix pack" section.
• In JRules V7.0, the update process was different: installing the latest V7.0.X version meant installing a new instance of the product in the new folder (the installation order and need to re-deploy the Java EE module remained the same).
• Starting from V7.5 (WebSphere Operational Decision Management), the fix pack updates are done using the IBM Installation Manager and a launchpad. See technote Installing WebSphere Operational Decision Management (WODM) V7.5.
