ORA-00371: no free buffer handles available

Cause: The value of the initialization parameter DB_HANDLES is too small.

Action: Shut down the instance, increase the value of DB_HANDLES in the initialization parameter file, and then restart the instance. Under normal circumstances, let DB_HANDLES take its default value by omitting the parameter from the initialization parameter file.

ORA-00372: file name cannot be modified at this time

Cause: An attempt was made to access a file being taken off line, or the database may be closing.

Action: Access the file after it is taken off line. Attempts will either succeed because the datafile is back online or fail with a message describing which file is off line. Repeat until successful.

ORA-00373: online log version num incompatible with Oracle version num

Cause: The online log was written by an incompatible version of Oracle. This can occur when the redo log file was created by either a newer or older version of Oracle.

Action: Recover the database using a compatible version, shut it down cleanly; then restart with the current software.

ORA-00374: parameter DB_BLOCK_SIZE = num invalid, valid range num..num

Cause: An invalid value has been used for the DB_BLOCK_SIZE initialization parameter.

Action: Adjust the parameter and restart the instance.

ORA-00375: unable to get default DB_BLOCK_SIZE

Cause: The system was unable to determine the default DB_BLOCK_SIZE.

Action: See the corresponding operating system-specific message. As a work-around, specify the block size with the parameter DB_BLOCK_SIZE in the initialization parameter file. See also your operating system-specific Oracle documentation.

ORA-00376: file name cannot be read at this time

Cause: An attempt was made to read from a file that is not readable. The most likely cause is that the file is off line.

Action: Check the state of the file. Bring the file online, if necessary.

ORA-00377: frequent backups of file name causing write operation to stall

Cause: Backups are occurring too frequently on this file. Each time a new backup is started for a file, any writes which have been previously issued (but not completed) have to be re-issued. If hot backups are started very, very frequently, it is possible that some writes will be re-issued repeatedly and never complete.

Action: Increase the interval between begin hot-backup commands for this file.

ORA-00378: buffer pools cannot be created as specified

Cause: Either the number of buffers or the number of LRU latches is too small to satisfy the specified buffer pool configuration.

Action: Either increase the number of buffers and/or number of LRU latches or configure smaller buffer pools.

ORA-00379: no free buffers available in buffer pool name

Cause: All buffers in the specified buffer pool are in use and no free buffers are available.

Action: Increase the number of buffers in the specified pool.
