Oracle Service Bus (11.1.1.4.0) on Ubuntu 10.10, deployment into ESXi Virtual Infrastructure

In our previous article, we installed Oracle SOA Suite PS3 into a host on a Virtual Infrastructure.

This article discusses the installation of Oracle Service Bus 11.1.1.4.0 into the same middleware home of the SOA Suite. This is possible because Oracle has released OSB 11g as a component of SOA Suite of products. OSB 11g PS3 and SOA Suite 11g PS3 shares the same Oracle Weblogic Server version, 10.3.4.

Pre-requisite:
- Minimum swap space = 512MB. Instructions to add file-based swap space is available here.
- Java Runtime Environment. Reuse the one from previous installation of Oracle Service Bus
- NFS mount to the existing Oracle installation file system.
- oracle user account and oinstall group are created on the target host. Ensure identical uid and gid (in this case, 500 and 1001 respectively)

Required binary
- ofm_osb_generic_11.1.1.4.0_disk1_1of1.zip downloadable from Oracle website.

Installation Steps:
- unzip downloaded files to a temp folder. You will get 2 directories after unzip. Disk1 and Disk2
- cd to Disk1
- execute runInstaller. When asked for java directory, use the one (either Sun JDK or JRockit) installed in WLS.
- select the previously created middleware home of SOA Suite 11.1.1.4.0. This reduces the installation footprint because it contains the Oracle WebLogic Server 11gR1 (10.3.4) and the optional component Oracle Enterprise Pack for Eclipse (OEPE) required by the OSB 11.1.1.4.0. The other middleware home (of Weblogic Portal, wlpmw) cannot be used because it contains Oracle Weblogic Server 10.3.2 which is not compatible with SOA PS3/OSB PS3.

Oracle Server Bus OSB Installation Screens

Upon completion of OSB installation in a SOA Suite middleware home, the following elements are added to the inventory.xml file in the oraInventory/ContentsXML directory.

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 Service Bus in the same home as SOA Suite.

Happy OSB'ing,
