why would you need APIs for that? 1) (on unix) ps -ef|grep smon will tell you the instances running on the machine
2) ps -ef|grep tnsl will tell you the listeners 3) look at listener.ora in either $ORACLE_HOME/network/admin or /var/opt/oracle and it iwll give you the listener details as well as ports. Listeners don't listen on IP addresses 4) env|grep ORACLE will give you the listing of the current ORACLE_HOME 5) database user -- in sqlplus from an account with select any table: select username from dba_users will give you the database users. If you want currently connected users, check v$session I suggest a short session reading the Concepts and Reference manual might be in order --- bharat dighe <[EMAIL PROTECTED]> wrote: > Hi Folks, > > Does oracle provides any API's which can help user to > discover the information related to oracle setup? > These API's can be used for finding out > 1.
