RACCHECK est un outil développé par Oracle ayant pour
but de vérifier votre configurations Clusterware.
Il formule des suggestions et des conseils pour
modifier la configuration RAC afin de répondre aux best practice Oracle.
Cet outil vérifie les paramètres suivantes;
- Les paramètres du noyau OS, les packages et les
paramètres du système d'exploitation
- CRS / Grid Infrastructure
- SGBDR; paramètres de la mémoire et de base de
données
- Les paramètres et les statistiques de l'ASM.
J'ai eu l'occasion de testé l'outil sur un RAC
11.2.0.1, 2 nœuds sous une distrib. Oracle Enterprise Linux. Ah, avant d'oublié
c'est RAC installé sur VirtualBox c'est juste un bac à sable.
Pour information cet outil est supporté à partir de la
version RAC 10.2.0.1.
Avant de commencer il faut télécharger l'outil sur la
note MOS ID: 1268927.1

of the included audit checks require root privileged data collection . If sudo
is not configured or the root password is not available, audit checks
which require root privileged data
collection can be skipped.
1.
Enter 1 if you will enter root password for each host when prompted
2.
Enter 2 if you have sudo configured for oracle user to execute root_raccheck.sh
script
3.
Enter 3 to skip the root privileged collections
4.
Enter 4 to exit and work with the SA to configure sudo or to arrange for root access and run the
tool later.
Please
indicate your selection from one of the above options[1-4][1]:- 1

Comme vous pouvez voir l'outil propose de modifier de
nombreux paramètres, y compris les valeurs du noyau, la purge des fichiers
journaux, la configuration du réseau, les patchs recommandés et les options de
sécurité.
