Switch Log File: Explicitly force Oracle Database to begin writing to a new redo log
file group, regardless of whether the files in the current redo log file group are full.
When you force a log switch, Oracle Database begins to perform a checkpoint but returns
control to you immediately rather than when the checkpoint is complete.
Take Checkpoint: Force Oracle Database to perform a checkpoint, ensuring that all
changes made by committed transactions are written to datafiles on disk

Archive Logs Tab - Provides archived log information from the control file.
An archive log record is inserted after the online redo log is successfully archived or cleared.
If the log is archived twice, there will be two archived log records with the same THREAD#,
SEQUENCE#, and FIRST_CHANGE#, but with a different name. An archive log record is also inserted
when an archive log is restored from a backup set or a copy and whenever a copy of a log is
made with the RMAN COPY command.
Name: Archived log file name
Sequence #: Redo log sequence number
Thread #: Redo thread number
First Change #: First change number in the archived log
Completion Time: Time when the archiving completed
Archived: Indicates whether the online redo was archived or whether RMAN only inspected the
log and created a record for future application of redo logs during recovery
