After an Oracle Grid Infrastructure upgrade, the password for the Oracle Database Quality of Service (QoS) Management administration account (qosadmin) needs to be reset and any users created before the upgrade need to be re-created.

Workaround:

Reset the password for the Oracle Database QoS Management administration account (qosadmin) after the upgrade completes by running the following command as a grid operating system user:

qosctl qosadmin -setpasswd qosadmin

The new password must be entered (there will be no prompt for the old password).

To re-create the Oracle Database QoS Management application users, perform the following steps as a grid operating system user:

1. Prior to upgrading Oracle Grid Infrastructure, run the following command to list the current list of defined users:

   qosctl qosadmin -listusers

2. After the upgrade, each user can be added by running the following command:

   qosctl qosadmin -adduser <user_name>
