Dernièrement un client m’a confié la délicate mission à ses yeux d’ajouter des noeuds supplémentaires au cluster RAC de pré-production, la principale motivation de cette demande provenait du fait que le contrat ULA (Unlimited License Agreement) arrivait prochainement à terme. Aussi pour bénéficier des conditions financières tout particulièrement avantageuses de ce contrat, il nous a fallu déployer dans les plus brefs délais de nouveaux noeuds pour pouvoir anticiper des futurs besoins de scalabilité des applications.
La procédure d’ajout d’un noeud dans un cluster RAC demeure somme toute assez simple mais certaines précautions doivent être prises pour être le plus efficace possible et surtout le plus productif.
Roadmap de la procédure
Pour illustrer cette procédure, nous ajouterons un noeud supplémentaire rac3-test au cluster déjà constitué par deux noeuds (rac1-test, rac2-test)
Mais avant de dérouler la procédure d’ajout de noeud proprement dite, il y a quelques précautions à prendre pour garantir le bon déroulement de cette opération qui se décompose de la manière suivante :
- Précautions d’usage sur le noeud supplémentaire
- Déploiement de Grid Infrastructure
- Déploiement de la distribution Oracle Database Enterprise Edition
- Création de la nouvelle instance
Précautions d’usage sur le noeud supplémentaire
Pour des raisons de simplicité d’installation, nous sommes partis d’un clone du système Linux d’un des noeuds existants pour déployer la distribution Linux sur le nouveau serveur, il nous a suffit ensuite d’adapter les adresses IP et le nom du serveur pour être en conformité avec la cible désirée.
Ces précautions concernent la déclaration des adresses IP (privée et virtuelle) du nouveau noeud, la visibilité des disques ASM et la création des répertoires d’accueil des binaires de grid infrastructure. Mais avant tout il est indispensable que le répertoire de l’inventaire Oracle OraInventory soit présent et respecte la même arborescence que celle définie sur les autres noeuds du cluster (rac1-test, rac2-test).
- Se connecter sous le compte root du nouveau nœud rac3-test
[root@rac3-test ~]# su -
- Vérifier l’existence des adresses privées et virtuelles dans le fichier /etc/hosts, dans le cas où celles-ci n’existeraient pas il faudrait les initialiser dans le fichier
[root@rac3-test ~]# cat /etc/hosts # Adresses virtuelles 10.xxx.xx.53 rac1-test-vip 10.xxx.xx.54 rac2-test-vip 10.xxx.xx.55 rac3-test-vip # Adresses privées 10.xxx.xx.103 rac1-test-priv 10.xxx.xx.104 rac2-test-priv 10.xxx.xx.105 rac3-test-priv
- Vérifier l’existence des packages Oracle asmlib
[root@rac3-test ~]# rpm -qa | grep asm oracleasm-2.6.18-238.el5-2.0.5-1.el5 oracleasm-support-2.1.4-1.el5 oracleasmlib-2.0.4-1.el5
- Vérifier la configuration ASMLIB
[root@rac3-test ~]# oracleasm configure ORACLEASM_ENABLED=true ORACLEASM_UID=oracle ORACLEASM_GID=oinstall ORACLEASM_SCANBOOT=true ORACLEASM_SCANORDER="" ORACLEASM_SCANEXCLUDE=""
- Initialisation de la librairie ASMLIB et découverte des disques ASM

- Création du répertoire d’accueil pour Grid infrastructure sur le nouveau nœud et tout particulièrement du répertoire oraInventory, pour cela nous allons nous positionner dans le répertoire /app qui est le répertoire racine de l’installation de tous les composants Oracle
[root@rac3-test app]# mkdir grid [root@rac3-test app]# chmod 770 grid [root@rac3-test app]# chown root:oinstall grid [root@rac3-test app]# mkdir oraInventory [root@rac3-test app]# chmod 770 oraInventory # Répertoire de l'inventaire Oracle sous le compte root [root@rac3-test app]# chown root:oinstall oraInventory [root@rac3-test app]# mkdir oracle [root@rac3-test app]# chmod 770 oracle [root@rac3-test app]# chown oracle:oinstall oracle [root@rac3-test app]# mkdir -p grid/11.2.0 [root@rac3-test app]# chown root:oinstall grid/11.2.0 # ORACLE_HOME de Grid Infrastructure [root@rac3-test app]# chmod 770 grid/11.2.0
Déploiement de Grid Infrastructure
L’avantage principal du script fourni par Oracle ‘addNode.sh‘ est le fait que la distribution Grid Infrastructure est automatiquement déployée sur le nouveau noeud à travers le réseau à l’identique de celle du noeud d’origine en terme d’arborescence et de binaires, dans notre cas de figure le propriétaire de la distribution grid infrastructure est ‘oracle’ aussi il est impératif que cet utilisateur puisse établir une connexion ‘ssh’ sur le nouveau noeud.
- Avant d’effectuer le déploiement de la distribution Grid Infrastructure il est recommandé de vérifier avec ‘cluvfy’ les prérequis de l’installation d’un nouveau noeud à partir du node 1 rac1-test.

The following configuration scripts need to be executed as the "root" user in each cluster node.

To execute the configuration scripts:
1. Open a terminal window
2. Log in as "root"
3. Run the scripts in each cluster node

Création de la nouvelle instance
Ne disposant pas des bibliothèques X11 sur le nouveau noeud, nous allons créer la nouvelle instance ‘RACDB3’ manuellement mais dans le cas où les bibliothèques X11 seraient présentes vous pouvez très bien utiliser l’assistant de création de base de données ‘dbca’ pour effectuer cette opération.
