Landing Oracle today has a ORA-01031 error (essentially, insufficient permissions), by querying the Oracle Login authentication method, using SYSDBA identity to connect to the database instance, the authentication method used is the operating system authentication, This authentication procedure is the process by which the operating system verifies that the user can connect to the database based on the information it manages.
So, I added the user who I logged into the operating system to the ORA_DBA group.
Specific operation: Run input Compmgmt.msc, and then locate it in the groups of local Users and Groups ORA_DBA, right-click Properties-Add-advanced-Find-senlinchen Now (find the user logged into your operating system)-OK-ok-ok.
Through the above method can be solved.
--Operating environment:
Os:windows10_x64 Education Edition
