Script d'audit de bases de données ORACLE

De wikiGite

-- 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 LIST   ******
-- AMELIORATIONS GLOBALES (AU SCRIPT)
--------------------------
-- TODO : INDIQUER SI L'INSTANCE EN COURS UTILISE IUN SPFILE OU UN INIT.ORA
-- TODO : UTILISER DES VARIABLES EN DEBUT DE SCRIPT POUR LES SEUILS D'ALERTES ?
-- TODO : affiner les stats d'opérations ASMM (variation des tailles de pools) avec v$sga_resize_ops et v$sga_dynamic_components
-- select component, current_size from v$sga_dynamic_components;
--select component,oper_type,oper_mode,initial_size/1024/1024 "Initial",TARGET_SIZE/1024/1024 "Target",FINAL_SIZE/1024/1024 "Final",status from v$sga_resize_ops order by component;

-- TODO : Faire une table des matières (ancres HTML)
-- TODO : Remplacer les fonctions de colorisation PL/SQL par du javascript ?
--     Note : Javascript inséré systématiquement en haut du fichier HTML produit, réutilisable dans les requêtes ?
-- TODO : ajouter chemin des archivelogs si ARCHIVELOG MODE (trouver le(s) log_archive_XXX remplis)
-- TODO : coloriser les requêtes gourmandes qui prennent plus de XXX microsec ou XXX buffers
-- TODO : Remplacer "Néant" par "N/A" ? ou "Aucun" ? pour éviter l'accent
-- TODO : Section SCHEMAS = Liste des grants par user et par role non systeme
-- TODO : Afficher N/A si 1er audit ou aucuns objets utilisateurs
--
-- AMELIORATIONS LOCALES (AUX SECTIONS)
-------------------------
-- TODO : Volumetrie = Insérer un graphe evolution volumétrie (attention aux creations de fichiers entre deux audits)
-- TODO : AJOUTER %LIBRE SUR TABLESPACES (comment gérer les autoextend ?)
-- TODO : mettre la ligne complète en rouge si aucun des datafiles n'est en autoextend, et que le "LIBRE" arrive à 90% du "TOTAL"
-- 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 : Afficher N/A si 1er audit
-- TODO : Detail UGA par utilisateur = Garder le nombre de session dans HISTAUDIT pour graphique d'evolution et moyenne
-- TODO : 'volumetrie tables et index' = A la creation des données d'audit, afficher au moins le total des tables et index, 
--         meme s'il n'y a pas de difference à afficher
-- 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
-- TODO : "tables et index dans le meme tbs" = grouper par user et tbs et ne donner que le nbre d'objets
-- TODO : 'affichage des logs' = grouper les messages et afficher une somme pour limiter le nombre de ligne ?
