Move the redo file path, the default redo log file path is the same as the Archivelog path, in the flashback area, because the flash back zone has a size limit, so redo log and archive log, especially archive log, will burst into the flashback zone. For the sake of specification, redo log and archive log must be placed in a separate

In the oracle10g and 11g versions, the ORACLE default log archive path is the Flashback recovery area ($ORACLE _base/flash_recovery_area). For this path, Oracle has a limitation, that is, the default is only 2G of space, and not just the default

1. directpath reads description In versions earlier than Oracle 11g, if a full table scan is performed on a large table, the wait event is: DB file scattered read; in 11g, if a full table scan is performed on a large table, wait event is: direct path read; that is, in 11 GB, full table scan of large tables directly reads data blocks into the PGA region of the session.
