NuxOra – Linux and Oracle IT website

J’ai recu une demande pour savoir comment générer un rapport AWR sous Oracle.

Voici un petit exemple pour se connecter à la base et générer un AWR en mode test

[root@nuxora01 ~]# su - oracle

[oracle@nuxora01 ~]$ export ORACLE_SID=nuxodb

[oracle@nuxora01 ~]$ sqlplus system@nuxodb
