Persistent connection to Oracle with OCI

Hi again to everybody, first sorry for my poor english. im trying to use persistents connections to an Oracle Database through PHP, for manageing transactions, and have some problems. My Schema: * Web Server: Apache 1.3.20 on a Linux RedHat 7.0 * PHP: 4.0.6 compiled with oracle module functions (OCI*) * Data Base: Oracle 8.0.5 on a Windows NT Server I need to manage transactions to database. For it i made a test pages like this: * 1 index page that generate some frames and open a persistent connection to Oracle * 1 frame that made an insert to one table of the database, and reopen the persistent connection * 1 frame that made an insert to another table of the same database, and reopen the persistent connection * 1 frame with 2 buttons, one for execute a Commit and another for execture a Rollback When i was using the ORA_* functions, some times works well, but other times not work correctly... Now using the OCI* functions dont work. What im doing wrong? Can somebody help me? Avanced thanks
