Notes:

Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here.

 With each z/VM LPARs , each Instance (or Guest) may have multiple virtual IFLs

 One z/VM guest can be associated with multiple Oracle databases



5


System z Linux & WebLogic Install Prerequisites

 WebLogic is referred to as Oracle WebLogic Server 11gR1 (10.3.2) and

"Oracle WebLogic Server 11g“

 Download from OTN the "generic" Oracle package installer (it is not specific to Linux on System z)

 X-Term; RealVNC, TightVNC….others

– www.realvnc.com

– www.tightvnc.com

 Red Hat EL 4 (UL7+), Red Hat EL 5 (UL3+)

 Novell SuSe 10 (SP2+)

 IBM Java 6 64bit (SR4 or higher) product is NOT supplied with any of the

Linux distributions, so you will need to download at the following url: http://www.ibm.com/developerworks/java/jdk/linux/download.html

 Installation Modes : Console, Graphical, Silent (Linux for System z Release Notes recommend using Console mode)

 Oracle Universal Installer (OUI) GUI interface to install WebLogic



6


Component Installation Steps…

1.

Preparation for Linux Install on System z

(SLES10 or RedHat)

2.

Install Novell SLES10 SP2 or RedHat

 Novell SLES10 used in examples that follow

3.

Install IBM Java 6 64bit (SP7)

4.

Install WebLogic



7


Installing Linux on System z – Step 1 (SLES10)

 Linux must first be installed either standalone in a Logical Partition

(LPAR) or under z/VM

 This example will install Novell

SuSe 10 SP2 Linux under z/VM

 With a z/VM instance created:

– a parmfile, kernel and an initrd file are FTPed to z/VM

– These 3 files are then executed, and as part of the execution, we IPL the kernel in storage and start the install

• In LPAR mode; we will mount the

1 st SLES10 CD #1 into the HMC





8


Installing Novell SLES10 SP2 – Step 2

 Easier to unload the SuSE CDs (usually 4 of them) to disk prior to starting the install

 Verify that all the media is unloaded and a mount point has been established

 Install using an X-Term session or your Browser

– http://xx.xx.xx.xx

:5801 (where xx.xx.xx.xx is your IP address) to access the install panels within z/VM

– Start an X-Term (VNC) session

• All examples that follow use a VNC X-Term session



9


Installing Novell SLES10 SP2 – Step 2-continued

 Open the VNC icon on your desktop and enter the IP address and 1. “:1” designates the VNC server instance to be used.

• http://xx.xx.xx.xx:

1

 Installation panels will prompt for configuration parameters, beginning with Language.

– Continue on and select options by clicking thru configuration panels



10


Installing IBM Java 6 64bit – Step 3

 Download: www.ibm.com/developerworks/java/jdk/linux/download.html

 SR7 under ‘Download’ in the row for 64Bit System z Java (User registration required)



11


Installing IBM Java 6 64bit – Step 3-continued

 Once downloaded, you must untar and decompress the file. Use the following command:

– tar –xzvf /<enter your directory>/ibm-java-sdk-6.0-7.0-linuxs390x-tgz or

– gunzip -c /<enter your directory>/ibm-java-sdk-6.0-7.0-linuxs390x.tgz | tar -xvf - > javaunpack.txt

 Java 6 can/will then be installed

Software Download Notes

 A complete list of supported configurations can be found at:

– http://download.oracle.com/docs/cd/E13196_01/platform/suppconfigs/index.html

 Release Notes Middleware 11gR1 for IBM: Linux on System z (WLS 10.3.2) are accessible: http://download.oracle.com/docs/cd/E15523_01/doc.1111/e15731/toc.htm

 Verify you have adequate “tmp” space when you unzip

 You will notice WebLogic is referred to as Oracle WebLogic Server 11gR1

(10.3.2) and "Oracle WebLogic Server 11g".

 You download from OTN the "generic" package installer. It is not specific to

Linux on z.

 The IBM Java SDK 6 64-bit SR4 (or higher) is required. At this time we recommend you stay with SR4"

 At this time the download is only on OTN - it is not yet on edelivery.oracle.com

even though the release notes point to that url (as of 4/2010).



16


WebLogic Terminology & Definitions

 WebLogic Domain

– A WebLogic Server administration domain is a logically related group of

WebLogic Server resources.

– Domains include a special WebLogic Server instance called the Administration

Server , and you configure a domain to include additional WebLogic Server instances called Managed Servers .

• Administrative Server

– One instance of WebLogic Server in each domain acts as an Administration Server.

The Administration Server provides a central point for managing a WebLogic Server domain.

• Managed Server

– All other WebLogic Server instances in a domain are called Managed Servers.

• In a domain with only a single WebLogic Server instance, that server functions both as Administration Server and Managed Server.

 Node Manager

– Utility which allows lifecycle control of an Administration Server and Managed

Server instances from a remote location. A Node Manager process is associated with a specific machine .



17


WebLogic Installation Planning Requirements

 Default Ports; 7001, 7010
