We're encountering the following error message while installing single tier PAO6.2 instance, "ORA-01033: Oracle initialization or shutdown in progress".
The database was not open; it had been started in mount stage but not opened.
The user is trying to install PAO6.2 to monitor the standby database and only wants to monitor the database while in mount stage which is not possible.
The database must be open to install the StealthCollect agents and monitor the database with Performance Analysis. Please verify the database is open prior to installing StealthCollect agents.
