Start by installing Oracle Instant Client basic and devel/sdk provided by oracle from this link http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html
On Fedora you will have to apply the following commands:
yum install oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpm
yum install oracle-instantclient11.2-devel-11.2.0.3.0-1.x86_64.rpm
Now you can install php_oci8 from pecl with pecl install oci8. Then enable
oci8 on php by adding extension=oci8.so on your php.ini.
Now it’s time to configure your zend application with the correct config params. In my case, I’m using the following:
resources.db.adapter = 'oracle'
resources.db.params.host = '127.0.0.1'
resources.db.params.username = 'dbuser'
resources.db.params.password = 'dbpass'
resources.db.params.dbname = '(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl) ) )'
resources.db.params.persistent = true
Done! Now you can use your db adapter for Oracle as you would with MySQL.
