Oracle has recommended a UNIX file structure (known as Optimal Flexible Architecture, OFA) for Oracle Database installation and is documented in the Oracle Database Installation Guide.
In our example, we install Oracle SOA Suite 11.1.1.4.0 into the directory structure of an existing Oracle Database 11.2.0.1.0.
Pre-conditions
1) You must have an existing oracle database installation, on a file directory structure compliant to Optimal Flexible Architecture (OFA). For instructions to install Oracle Database 11g, please refer to this article.
2) Both servers (Oracle Database server and Oracle Service Bus server) must share the common oracle user and oinstall group with identical uid and gid. You can implement this either with NIS (the yellow pages, yp), NIS+, rsync or LDAP. The latter is the preferred but I will leave this exercise to a separate article. For now, just create the oracle user and oinstall group manually on the SOA Suite host.
3) Both server should mount the NFS exported file system using the same convention, either u01 or disk01 as recommended by Oracle. On my machine, I mapped the exported FS by specifying the following in /etc/mtab file.
192.168.50.100:/mnt/home_shared/sharedvol/u1 /u01 nfs rw,hard,intr,addr=192.168.50.100 0 0
SOA Suite Installation requires at least 512MB of swap space. If your default swap partition has less space than that, then the easiest way to increase the swap space is to follow the instructions here. I have my Ubuntu 10.10 Standard Operating Environment created with 1GB of swap partition and export it as a ESX ova template and re-use it for all my Oracle product installation.
Given that the target host is a multi-homed host, with a NIC for application and another for storage, I have updated the /etc/hosts file to ensure the hostname resolved into the correct IP address.

Bill of Materials
1) Oracle Weblogic Server 10.3.4 (wls1034_oepe111161_linux32.bin)
2) Oracle SOA Suite PS3 11.1.1.4.0 (ofm_soa_generic_11.1.1.4.0_disk1_1of2.zip, ofm_soa_generic_11.1.1.4.0_disk1_2of2.zip)
The following are typical steps to installing Oracle SOA Suite onto your target machine.
1) First, you must install Oracle Weblogic Servier 10.3.4 as oracle user.
 |
ORACLE_BASE = /u01/app/oracle MW_HOME = /u01/app/oracle/product/soamw |
 |
| We don't need support do we? |
 |
| Select the 'Typical' option, we will develop something on this installation |
 |
| WLS_HOME = /u01/app/oracle/product/soamw/wls_10.3 |
Unlike SOA Suite PS2 (11.1.1.3.0) which needs to be installed on top of SOA Suite 11.1.1.2.0, PS3 can be installed as a standalone package. As oracle user, unzip ofm_soa_generic_11.1.1.4.0_disk1_1of2.zip and ofm_soa_generic_11.1.1.4.0_disk1_2of2.zip into your /home/oracle folder.
5 folders (Disk1, Disk2, Disk3, Disk4 and Disk5) will be created after unzip operation. cd into Disk1 and execute runInstaller. When asked for JRE/JDK location, use the one installed with WLS. (wither Sun JKD or JRockit)
oracle@orasoa1:~/Disk1$ ./runInstaller
Checking if CPU speed is above 300 MHz. Actual 3296 MHz Passed Checking Temp space: must be greater than 150 MB. Actual 1583 MB Passed Checking swap space: must be greater than 512 MB.

Please specify JRE/JDK location ( Ex. /home/jre ),/bin/java should exist :/u01/app/oracle/product/soamw/jrockit_160_22_D1.1.1-3
If you see the following error on the console, you can ignore them (do nothing about them)

SOA Suite Installation Screens
 |
| Select the existing oraInventory of previous product installation |
 |
| Click 'Continue' to ignore the result of failed pre-requisite checks |
 |
| Specify the existing middle home (soamw) created during installation of Weblogic Server in Step 1 above. MW_HOME=/app/oracle/product/soamw |
 |
| The installer detected a compatible Weblogic Server version already exist in the selected MW_HOME |
 |
| Start the installation process by clicking the 'Install' button |
 |
| Click 'Next' to finish the installation |
 |
| Click 'Finish' to complete the installation |
The following image depicts the summary of the resultant directory structure after WLS and SOA installations.
The final step is to make sure your operating environment has the right variables set up.
As root,
#vi /etc/bash.bashrc
Add the following lines
export ORACLE_BASE=/u01/app/oracle export MW_HOME=$ORACLE_BASE/product/soamw export WLS_HOME=$MW_HOME/wls_10.3
save the file.

Voilà, Oracle SOA Suite on OpenFiler NFS.
Happy SOA'ing.
If pre-requisites fail, it implies that the software is not compatible for installation on ubuntu. How did you work ahead with this SOA Suite installation even after failure?
ReplyDeleteHi apmandal, I would not equate 'incompatible' with 'unsupported'. Ubuntu platform is unsupported, it doesn't mean one cannot run the Oracle products on it. All x86 Linux platform is binary compatible. Hope this makes sense.
