Zend Core for Oracle is developed in partnership with Zend Technologiesand can be downloaded from Oracle’s OTN web site. This product is easy to install and fullyintegrated with Oracle. In Oracle Database 11g, Oracle provides enhanced support for PHPwith the database. Oracle provides a feature called Database Resident Connection Pooling(DRCP) to provide considerable improvement in the scalability of PHP applications. In essence,DRCP provides a shared pool of connections similar to the way multithreaded sessions work.This allows for persistent connections without having to dedicate one for dedicated serverprocesses for each of the PHP persistent connections.From the application tier, you must append the following option to the connect string:(SERVER=POOLED). In the OCISessionPoolCreate() application call, you must specify this *connStr asan argument.OCISessionPoolCreate ( OCIEnv*envhp,OCIError *errhp,OCISPool *spoolhp,OraText**poolName,ub4*poolNameLen,const OraText *connStr,ub4connStrLen,ub4sessMin,ub4sessMax,ub4sessIncr,OraText*userid,ub4useridLen,OraText*password,ub4passwordLen,ub4 mode );
