Enum oracle::ShutdownMode
[−]
[src]
pub enum ShutdownMode { Default, Transactional, TransactionalLocal, Immediate, Abort, Final, }
Database shutdown mode
Variants
Default
Further connects are prohibited. Waits for users to disconnect from the database.
Transactional
Further connects are prohibited and no new transactions are allowed. Waits for active transactions to complete.
TransactionalLocal
Further connects are prohibited and no new transactions are allowed. Waits only for local transactions to complete.
Immediate
Does not wait for current calls to complete or users to disconnect from the database. All uncommitted transactions are terminated and rolled back.
Abort
Does not wait for current calls to complete or users to disconnect from the database. All uncommitted transactions are terminated and are not rolled back. This is the fastest possible way to shut down the database, but the next database startup may require instance recovery. Therefore, this option should be used only in unusual circumstances; for example, if a background process terminates abnormally.
Final
Shuts down the database. Should be used only in the second call to shutdown_database after the database is closed and dismounted.
