4.8 Creating Administrative Users for Oracle Database QoS Management

Oracle Database QoS Management provides a command line utility named QOSCTL to help you manage users. This utility is installed on each node of the cluster but runs properly only if executed as the Oracle Clusterware administrator user on the same node on which the Oracle Database QoS Management server is running. The correct node to run the utility on can be determined by issuing the following command:

srvctl status qosmserver

The QOSCTL utility supports the creation of Oracle Database QoS Management administrative users. The account information is stored in the local system-jazn-data.xml file with encrypted credentials. The account information is also stored in the Oracle Clusterware Repository (OCR) to support failover of the Oracle Database QoS Management Server.
