How to get the information like IP address,Host name of connected clients v

Question

Hi Every one,
I want to get the information like (IP Address,Hostname,Active sessions , Database Server….etc) of the connected clients
via V$Views(ORACLE).
And then I like to load these infromation into a table “Client_Table”.
Could some one give me suggestion that which V$ views/method I use in order to get the above information and then
how to load these information into a table “Client_table”?
Your suggestions will be highly appreciated.
With Regards

You could use a LOGON TRIGGER so every session insert its own environment into your client_info table.
You could use the following view and choose whatever attribute you need:
create or replace view my_userenv (
AUDITED_CURSORID ,
AUTHENTICATION_DATA ,
AUTHENTICATION_TYPE ,
BG_JOB_ID ,
CLIENT_IDENTIFIER ,
CLIENT_INFO ,
CURRENT_SCHEMA ,
CURRENT_SCHEMAID ,
CURRENT_SQL ,
CURRENT_USER ,
CURRENT_USERID ,
DB_DOMAIN ,
DB_NAME ,
ENTRYID ,
EXTERNAL_NAME ,
FG_JOB_ID ,
GLOBAL_CONTEXT_MEMORY ,
HOST ,
INSTANCE ,
IP_ADDRESS ,
ISDBA ,
LANG ,
LANGUAGE ,
NETWORK_PROTOCOL ,
NLS_CALENDAR ,
NLS_CURRENCY ,
NLS_DATE_FORMAT ,
NLS_DATE_LANGUAGE ,
NLS_SORT ,
NLS_TERRITORY ,
OS_USER ,
PROXY_USER ,
PROXY_USERID ,
SESSION_USER ,
SESSION_USERID ,
SESSIONID ,
TERMINAL
