How do I install/upgrade OCI8 on Oracle Application Server or Oracle HTTP Server?
Oracle Application Server 10g’s HTTP server includes PHP 4 and the OCI8 extension. Users often want to upgrade to recent versions of PHP and OCI8.The Underground PHP and Oracle Manual has a section with steps for this. The delicate part of re-installing PHP on OHS is avoiding Oracle library version clashes. Ideally PHP OCI8 should be built and run with the same version of Oracle libraries.
