This document describes how to install Rational® Developer for System zTM Interim Fix 6 for 8.5.x, 9.0.x and 9.1.x – IBM Java Platform Standard Edition 7 Service Refresh 9 Fix Pack 20. This iFix is provided as an update and installed using IBM Installation Manager. The update is generally installed directly from the IBM update server, however you can also choose to download an archive file that contains the update and then use IBM Installation Manager to perform local installations. The following sections describe how to install this update.
Workstation:
This update is applicable to the following
product versions:
IBM Rational® Developer for System z V8.5.x
IBM Rational® Developer for System z V9.0.x

Follow the steps below to install the update. You should perform the installation using the same user account that originally installed the IBM Rational Developer for System z product.
To install directly from the IBM update server:
Start IBM Installation Manager.
Click Update.

Select the package group in which you installed IBM Rational
	Developer for System z (version 9.0 shown). The default is IBM
	Software Delivery Platform. The Installed Packages list at the
	bottom of the panel should show IBM Rational Developer for System z
	(version 9.0 shown) as one of the entries. Click Next. 
Select IBM Java SDK 7.0 SR9 FP20 and any other
	required or optional updates from the list of available updates.
	Click Next.
Review your selections on the
	Summary panel. If you want to make any changes to your selections,
	click Back and make your changes. When you are ready to
	install the update, click Update.
Note: Depending
	on the speed of your computer processor, the amount of RAM, and the
	speed of your Internet connection, the update(s) could take an
	extended period of time to download and install. 
	
When the updates are complete, a message will be displayed by
	IBM Installation Manager informing you that updates were
	successfully installed. You can click View Log File to view
	the log file for the current Installation Manager session. When you
	are finished, click Finish.
Exit IBM Installation Manager and start IBM Rational Developer for System z.
Ideally, this update should be installed directly from the IBM update server, as described in the Workstation installation instructions section above. However, you may also download an archive file containing the update and perform local installations. You might want to do this if:
You have a slow or unstable Internet connection and want to use a download manager that can resume the download.
You have difficulty accessing the live IBM update servers from behind a firewall.
You prefer to download the update and install it later.
Download the RDz85x90x91xiFixJava7SR9FP20.zip file from the support website.
Unzip RDz85x90x91xiFixJava7SR9FP20.zip to a folder on your system. These files are temporary and may be deleted after the installation is completed.
Start IBM Installation Manager.
From the menu bar, select File > Preferences This is where you will tell the IBM Installation Manager the location of the installation files you just extracted.
Click Add Repository in the Preferences
	dialog.
In the Add Repository dialog, browse to the directory
	where you extracted the update installation files. Inside that
	directory you will see a rational folder. Change to the
	rational\RDz85x90x91xiFixJava7SR9FP20 directory,
	select repository.config and then click OK. 
Click Test Connection and ensure that the repository
	can be found.
Click OK.
Now that the local repository has been set, follow the instructions outlined in the Workstation installation instructions section above.
You can install product updates, such as interim fixes and Fix Packs, from a command line so that you do not have to monitor or input information during the installation. For more information about installing product updates from a command line, see Working with silent installations in the IBM Installation Manager help.
You can verify that the update is installed by running IBM Installation Manager - View Installed Packages. You should see IBM Java SDK 7.0 SR9 FP20 Version 7.0.9.2 (7.0.90020.20151204_1515) listed.

Depending on your current Installation Manager preferences and your installation history, you may be able to remove the Rational® Developer for System zTM Interim Fix 6 for 8.5.x, 9.0.x and 9.1.x – IBM Java Platform Standard Edition 7 Service Refresh 9 Fix Pack 20 update using the following steps:
Start IBM Installation Manager from the Windows Start menu. By default this is under Start > All Programs > IBM Installation Manager > IBM Installation Manager.
Click Uninstall
Select the IBM Java SDK 7.0 SR9 FP20 entry you want to uninstall. Click Next.
