Installing Oracle SOA Suite atop XE Database
Posted by Sébastien Stormacq in Oracle on 20/01/2011
Although not officially supported, installing Oracle SOA Suite a top of the lightweight XE database is often convenient for development, demo or training purpose. It avoids going through the complete installation of her big brother : the complete Oracle Database 11g system.
XE is less than 220 Mb download and Installing it on a Linux system is as simple as rpm -ivh oracle-xe.rpm However, there is some caveats, i.e. some system parameters to tweak before installing SOA Suite’s database schemas using Repository Creation Utility (RCU). |
In the same spirit as my previous blog entry : here are the magical incantations for the database gods, to be executed before RCU.
First connect to the database :
sqlplus sys/yourpassword@XE as sysdba
(be sure to have /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin in your PATH)
SQL> show parameter processes //processes should be 40 – must be 200
SQL> alter system set processes = 200 scope=spfile;
SQL> show parameter session;
SQL> alter system reset sessions scope=spfile sid='*';
SQL> shutdown immediate;
SQL> exit;
then restart XE with :
sudo /etc/init.d/oracle-xe start
Finally, as stated on SOA Suite download page :
“If you want to use XE you can set the RCU_JDBC_TRIM_BLOCKS environment variable to TRUE *prior* to running RCU. As a reminder as to support level, when running RCU against XE you will receive a warning stating that the database version is not supported by Oracle.”
You must issue
export RCU_JDBC_TRIM_BLOCKS=true
before starting RCU. Failing to do so will cause WebLogic to issue a bunch of database related exceptions at startup time.
That’s it ! You can now proceed with RCU to install SOA Suite’s database schemas.
Enjoy !
