Introduction

Oracle release the Webcenter Patchset 4 (PS4),  version 11.1.15, recently and I am in the process of installing/testing this product. I am going to document my observations for future reference and hope it helps out others in the process.

Download files here: http://www.oracle.com/technetwork/middleware/webcenter/downloads/index.html

Read Oracle’s Documentation here: http://download.oracle.com/docs/cd/E21764_01/install.1111/b32474/start.htm#ASINS101

The Process…

The process is quite simple, I download Installers from Oracle’s Middleware/Webcenter site, selected the appropriate version and ran them on Oracle Enterprise Linux (OEL) version 6.0 … the OEL version here is the important part because there were a few issues related to the PS4 installers and OEL v6.

Anyways, here is what I downloaded

• wls1035_linux32.bin – Oracle WebLogic Server 11g R1 (10.3.5)
• Update: I should not used this. Turns out I was given a 64bit JVM and the “rcu exception in thread “main” java.lang.unsatisfiedlinkerror”  is the symptom for it
• Solution: Goto oracle.com and download the 64bit Weblogic 10.1.3.5 jar and then separately download the 64bit jdk
• ofm_rcu_linux_11.1.1.5.0_disk1_1of1.zip – 11.1.1.5 RCU (I got the 32 bit one first and then the 64 bit one and both were named the same)
• ofm_wc_generic_11.1.1.5.0_disk1_1of1.zip – Generic Oracle WebCenter Release 11g R1 (11.1.1.5.0)

I have a virtual machine, as mentioned earlier… VM: OEL 6

And another VM with the database … DB: Oracle 11g

Before you start….

Check you Linux install has the right libraries (see Appendix-A). There seems to be an issue with the X11 libraries and the RCU installer. Do a “rpm -qa” and grep for “X11”
make sure you have the i386 libaries or else you will see the following error (“blah blah libXext.so.6 is missing”)

Failed to initialize logger with location :/home/oracle/tmp/rcuHome/rcu/log/logdir.2011-05-26_00-01/rcu.log
Initializing logger using the following location :/tmp/logdir.2011-05-26_00-01/rcu.log
Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/oracle/tmp/rcuHome/jdk/jre/lib/i386/xawt/libmawt.so: libXext.so.6: cannot open shared object file: No such file or directory
        at java.lang.ClassLoader$NativeLibrary.load(Native Method)

This issue was fixed by going back to the DVD installer and selecting additional libraries for the 64bit OEL 6 install.

Finally once you have the right library, if you do not have your X11 stuff setup you will get the following errors:

[oracle@pdemora140rhv bin]$ ./rcu
Failed to initialize logger with location :/home/oracle/tmp/rcuHome/rcu/log/logdir.2011-05-26_22-07/rcu.log
Initializing logger using the following location :/tmp/logdir.2011-05-26_22-07/rcu.log
Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using 'xx.xx.xx.xxx:0' as the value of the DISPLAY variable.
        at sun.awt.X11GraphicsEnvironment.initDisplay(Native Method)

Setup your DISPLAY in the following manner

• Get an XServer, Install and Run it . Example: Get XMING

(See Related Blog Post Here: )

• Goto your “rcuHome/bin” and do “./rcu“

Running the installers ….

Download:  So earlier we downloaded the following

wls1035_linux32.bin – Oracle WebLogic Server 11g R1 (10.3.5)
ofm_rcu_linux_11.1.1.5.0_disk1_1of1.zip – 11.1.1.5 RCU (I got the 32 bit one first and then the 64 bit one and both were named the same)
ofm_wc_generic_11.1.1.5.0_disk1_1of1.zip – Generic Oracle WebCenter Release 11g R1 (11.1.1.5.0)

Now we can begin moving, extracting and installing. Start with the Weblogic Server, then run the RCU tool and finally install Webcenter.

1.  SCP:  Move the downloaded files to your VM using SCP (I put them under /home/oracle/tmp) and unzip (simply use “unzip filename.zip”)
2. Change Permissions: Make the WLS Installer Executable  chmod +x wls1035_linux32.bin
3. Run: the installer “./wls1035_linux32.bin”
4. Check: This should create the weblogic home with the following structure

 drwxr-x---. 6 oracle oracle  4096 May 25 21:13 coherence_3.6

Install the Webcenter/UCM schemas using the RCU tool….
