OciLogoff, oracle sessions & OCIInternalDebug

Hello there, If I have a page that starts with OCILogon , and ends with OCILogoff command, does Oracle still keep a session open? Would using persistent connections reduce the number of sessions used? I have encountered the infamous Ora-00018 error. I get false errors, such as "invalid column name" (because the query works just fine)...Then, if you wait a few minutes, the error goes away and the page performs as designed. I am able to hit the session limit after running through my pages roughly 60 times (the default Oracle sessions value, I've learned). Am I mistaken to assume that OCILogoff() frees up these sessions? It all happens relatively fast: 1. OCIlogon 2. run query 3. display query data in HTML 4. OCILogoff Also, since I have OciInternalDebug(1), I can see these messages on each screen: OCIDebug: START php_rshutdown_oci OCIDebug: END php_rshutdown_oci Any feedback is appreciated. -- Paul Fernandez Webmaster Structural GenomiX, Inc.
