the oci-driver will only open one server-connection per TNS-name/process. so if you use $a = ociplogon("scott", "tiger", "prod"); and later (different script) $a = ociplogon("system", "manager", "prod"); you will still only see one server connection (one "shadow") but you will have two sessions which share the one server-connection. so if you have more that one oracle-user that's used in your scriots you have to do: oracle-connections = MaxChilds oracle-session = MaxChilds * distinct oracle-logins now, if you limit the persistent connections per apache-child some logins would be fast whereby others would be slow, i really dislike this kind of unpredictable behaviour. if you have the need to connect more than one oracle-user i would either: - have different apaches running (one per oracle-user) - only use ociplogon for one of the users (starting a new session over an already established link is still fast) - not use oracle (just kidding;-) or, do you have any better ideas? re, tc > > Eric > > On Tue, 23 Jul 2002, Thies C.
