Failed Over

In a RAC environment, a user can connect to any one of the multiple instances in a cluster. If the connected instance fails, the session can be reconnected automatically to other available instance. This metric indicates whether the session is running in failover mode and failover has occurred (YES) or not (NO).

Failover Method

The failover method used for determining how failover occurs from the primary node to the backup node

Failover Type

Failover type settings: SESSION, SELECT, NONE

Fixed Table Sequence

This metric's value is incremented each time the session completes a call to the database. Lack of changes in this metric's value indicates that the selected session was idle during the selected time range.

Hard Parse Count

The number of hard parse requests performed by this session

Logical Reads

The number of logical reads performed by session since login. This value is the total summary of all requests for database blocks, irrespective of whether they were found in the database cache.

Logical Writes

The number of logical writes performed by the session since login.

The date and time when the user logged on to the database. The format is year/month/day and hours:minutes:seconds (on a 24 hour clock).

Module Name

The currently executing module name, set by DBMS_APPLICATION_INFO.SET_MODULE.

Oracle User Name

The Oracle database account of the started session

OS User Name

The operating system user used by the client

Parallel Status

The Parallel Query status; can have one of the following values:

ENABLED — the session is in a Parallel Query enabled mode

DISABLED — the Parallel Query enabled mode is not supported for the session

FORCED — the session has been altered to force Parallel Query)

PDB

In multitenant architectures, the name of the pluggable database

Physical Reads

The number of data blocks read by Oracle, which are not present in the buffer cache or in the PGA, thereby requiring I/O read operations, that is: the total number of data blocks read from disk.

Resource Consumer Group Name

The name of the session's current resource consumer group

Schema Name

The name of the database schema

Seconds in Wait

The wait event’s length of time, in seconds, since logon

Serial Number

The session’s serial number. The combination of SID and serial number provides a unique identification of the session.

Wait Class

The classification of wait events.

Top SQLs

The Top SQLs collection retrieves top n SQL statements (namely: statements that experienced the longest time of CPU consumption or total wait events during the specified time range) and their details.

Array Wastage

The gap (by a percentage) between the average number of rows per fetch that the array can hold, as defined in the arraysize parameter of the various fetch operations of the specified SQL query, and the number of rows actually retrieved.

For example: if the average setting of the arraysize parameter was 5, and the average number of rows actually retrieved per operation was 10, the value indicated will be 50.

Ideally, the value of this parameter is 0; any other value indicates the need for additional sql.net roundtrips per each SQL query execution.
