Script d'audit de bases de données ORACLE

-- AUDIT BASES ORACLE
-- 
-- Compatible Oracle 9i, 10g
-- FSo 2005-2010
-- Changelog
-- 2005    Creation du script, regroupement d'operations manuelles repetitives.
--         Generation de rapports format TXT
-- 12/2006 Creation table HISTAUDIT et requetes associees pour comparaisons entre 2 audits
-- 11/2008 Separation en 2 fichiers 1=audit de perfs 2=environnement schemas
-- 02/2009 Modifications des requetes audits de perfs pour generer des fichiers HTML
-- 02/2010 Affichage icones "info" et "tips" 
-- 06/2010 Ajout scan de l'alert.log
-- 08/2010 passage section schemas en HTML

-- ****** IMPORTANT ****** : le script doit etre lance par sqlplus, en tant que SYSTEM ******

-- Exemple, sous linux, en utilisant des variables et easyconnect :
-- SOURCE=/media/UDISK
-- SQLP=/usr/lib/oracle/xe/app/oracle/product/10.2.0/client/scripts/sqlplus.sh
-- AUDIT_ORACLE=$SOURCE/Audit_Oracle
-- connection='//server_oracle:1521/ORA'
-- $SQLP system/manager@$connection @$AUDIT_ORACLE/audit_complet_html

-- ******  NOTES / TIPS  ******
-- * NOTE 1 : ATTENTION AUX FORMATS DE COLONNES ALPHANUMERIQUES :
--   LE XX de "format aXX" DOIT TENIR COMPTE DES BALISES HTML
--   de TYPE "<td bgcolor="#3399CC" align=center>" QUI SONT
--   COMPTEES DANS LE TOTAL DE LA CHAINE DE CARACTERE
--
-- * NOTE 2 : AUTANT QUE POSSIBLE, NE PAS S'OCCUPER DES FORMATS COL
--   LAISSER PAR DEFAUT LES ALPHA ET UTILISER UN TO_CHAR(valeur,'format numérique') POUR LES NOMBRES
--
-- * NOTE 3 : Le script cree (ou re-cree) 2 fonctions et une table d'historique dans TOOLS
--
-- * TIP : inclure une image directement dans le code html :

-- TODO : fusionner Volumetrie tablespace et difference de taille (ajouter une ligne sous le titre avec 2 colonnes)
-- TODO : Diff taille dernier audit = Ne pas coloriser tbs types UNDO et TEMPORARY
--      Note : prob = on a pas le tbs type dans histaudit. Lier avec dba_tablespace pour detecter types TEMPORARY/UNDO ?
--      Note2: Exclure aussi SYSTEM et SYSAUX de la colorisation ?

-- TODO : Ajouter une colonne user, et grouper par user pour detecter d'eventuels users system oublies dans le NOT IN
-- plus une ligne total global à la fin du tableau
-- TODO : Intégrer le script de recompilation si le nombre d'INVALID > 0 et afficher le résultat
