Cet article présente la procédure pour déplacer un agent Cloud Contol 12c d’un répertoire vers un autre et/ou pour modifier le port de l’agent.

Cette opération est rapide à réaliser et peut être effectuée à chaud, un blackout de la supervision étant réalisé.
A noter que le nom de l’agent – avec l’ancien numéro de port – est conservé : <hostname>:<ancien port>.
Le prérequis est le téléchargement du script perl ConvertToStandalone.pl sur le support Oracle à partir de la note suivante : « EM 12c : How to Move / Migrate an AGENT BASE DIRECTORY to New Location ?(Doc ID 2021782.1) ».
– Se connecter avec le compte oracle sur le serveur de l’agent à déplacer :

mkdir

– Vérifier l’état de l’agent :

/agent_inst/bin/emctl status agent

– Recréer le fichier plugins.txt (cette étape est nécessaire en cas de déploiement de plugins) :

/core//perl/bin/perl /core//sysman/install/create_plugin_list.pl -instancehome /core/

– Contrôler la présence de fichier appartenant à root (modifier les droits des fichiers autre que /sbin/nm*) :

find  -uid 0

Si d’autres fichiers existent, modifier les droits des fichiers (root vers oracle).
– Supprimer le répertoire lost+found (si besoin) :

rmdir /lost+found

– Déplacer l’agent vers le nouveau répertoire :

export OLD_AGENT_HOME=/core/
export ORACLE_HOME=/core/
$OLD_AGENT_HOME/perl/bin/perl /tmp/ConvertToStandalone.pl -instanceHome /agent_inst -newAgentBaseDir

Migrating the agent home to different home
Validating the arguments
The log file is /agent_inst/install/logs/convert/convertingtostandalone_2015-07-20_16-15-51.log

Modifying the oragchomelist to include the current agent home with the instancehome
The migration is completed Successfully. Run /core//root.sh as root user manually.
Deinstall agent home /core/ manually.
