Redo Logs Panel

Redo Logs Panel

The Redo Logs panel, which displays details regarding all redo logs, either for the Oracle instance or for all nodes of an Oracle RAC, comprises the following sections:

•
Redo Logs Storage Groups table — click on a group list row to see the list of members in that group.
•
Members of Group [n] table — for details, see Members of Group [n] Table .
Redo Logs Storage Groups Table

The redo log records all changes made in datafiles.

 
Table 24. Redo Logs Storage Groups Table
Name
Description

Group #

The redo log group number.

Group Status

The status of the redo logs indicates which logs are in use and whether there are any odd status codes, such as stale log indications or indications of corrupt redo logs.

The log files can have one of the following status values:

•
USED — indicates either that a log had just been added (never used), or that a RESETLOGS command has been issued.
•
CURRENT — indicates a valid log that is in use.
•
ACTIVE — indicates a valid log file that is not currently in use.
•
CLEARING — indicates a log is being re-created as an empty log due to database administrator action.
•
CLEARING CURRENT — indicates that a current log is being cleared of a closed thread. If a log stays in this status, it could indicate there is some failure in the log switch.
•
INACTIVE — indicates that the log is no longer needed for instance recovery but may be needed for media recovery.

Archived

Indicates if the redo logs are being archived.

Sequence #

The number assigned by Oracle to each redo log file whenever a log switch occurs and LGWR begins writing to the log file. When redo log files are archived, the archived log retains its log sequence number.

Size

The size of the log in megabytes.

First Change #

A system-allocated number (SCN), which identifies the first time a change was recorded in this log.

First Time

The time when the first SCN in the log was recorded.

Alarms

The number of warning, critical, and fatal alarms for the selected Oracle database tablespace.

•
INVALID — indicates that Oracle cannot access the redo log file.
•
STALE — indicates a log file that is either corrupt or incomplete. If the log file’s group becomes the active group, the file becomes valid again.
•
DELETED — indicates an online redo log file that has been dropped from the database and deleted from the disk.
