Program history v9

Question

Hello,
Noob here, my customer asked the following: Tell me what programs these userids use. She thought v$session, but that's only current (I could query it as a job and build up a history).
We keep a session audit history, but it has the following cols (note program is not one)
HOST_NAME, DATABASE_NAME, DOMAIN_NAME, SESSIONID, ENTRYID,
STATEMENT, "TIMESTAMP#", USERID, USERHOST, TERMINAL,
"ACTION#", RETURNCODE, OBJ$CREATOR, OBJ$NAME,
AUTH$PRIVILEGES, AUTH$GRANTEE, NEW$OWNER, NEW$NAME,
SES$ACTIONS, SES$TID, LOGOFF$LREAD, LOGOFF$PREAD,
LOGOFF$LWRITE, LOGOFF$DEAD, LOGOFF$TIME, COMMENT$TEXT,
CLIENTID, SPARE1, SPARE2, OBJ$LABEL, SES$LABEL, PRIV$USED,
SESSIONCPU, STATUS_DATE,
to_char("NTIMESTAMP#") AS "NTIMESTAMP#", PROXY$SID,
USER$GUID, "INSTANCE#", "PROCESS#", XID, AUDITID, SCN, DBID,
SQLBIND, SQLTEXT
It's v9 so Hist_Active_Sess_History is not available.
Any help Gratefully accepted

You can't do it accurately using v$session so think again.
v9 is meaningless ... post a full and complete version number.
What you need is auditing.

Look for "executable procedure"
Then follow up by reading the docs at http://tahiti.oracle.com
