want to log all transaction made

hi all,

  i'm running Oracle8.0.5 server for linux, and i'm the dba. but there's been few
problems with our system on it, with few developers working on the server.
(php3, sql*plus , etc)
 and i want to track who's executing what (SQL lines).  is this possible ?
 or is there another solution?

 i want to at least be able to get a log of who logged in as who, and when to
the oracle server.( by sqlplus or win2000access )

 thanks,
