BG CPU Time

The amount of CPU time used by a session from the time a user call starts until it ends

BG Time

The amount of time used by a session from the time a user call starts until it ends

Blocking Session Status

The status of the blocking session; indicates whether the session is currently executing SQL statements (ACTIVE) or not (INACTIVE).

Client Info

The client information; contains the information set by DBMS_APPLICATION_INFO.SET_CLIENT_INFO

Client Machine Name

The name of the computer where the Client is running

Client PID

The operating system process ID for the Client program

Consistent Changes

The number of times a user process has applied rollback entries to carry out a consistent read on the block

Consistent Gets

The number of times a consistent read was requested for a block by this session

Current SQL

The last SQL statement executed by the user

DB Block Changes

The total number of changes that took part in an Update or Delete operation made to blocks by this session

DB Block Gets

The number of times a current block was requested by this session

DB CPU Time

Time spent waiting for the CPU to process SQL statements and other types of calls made to Oracle

DB Time

The amount of time used by the database for this session

Event

The name of the event that resulted in the wait event

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.

Logon Time

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.

Physical Writes

The number of physical writes carried out by the session since logon

Redo Entries

The amount of redo entries issues by the session since logon

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.

Server

The server’s type: DEDICATED, SHARED, PSEUDO. or NONE

Server PID

The operating system process ID for the Oracle shadow process.

Server Program Name

The server program name

Service Name

The service name of the session

Session Action

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

Session Cursor Cache Hits

The number of session cursor cache hits.

Session ID

The session identification number.

Session PGA Memory

The amount of PGA memory allocated for the current session

Session SQL ID

The session identification number for the SQL statement

Session Status

The session status; indicates whether the session is currently executing SQL statements (ACTIVE) or not (INACTIVE)

Session Type

The session type (USER or BACKGROUND)

Session UGA Memory

The amount of UGA memory allocated to the current session

Sort Disk

The number of sort operations that require creation of temporary segments on disk to store the intermediate sort results. This occurs if the data being sorted cannot be fit into memory block specified by the SORT_AREA_SIZE parameter in the init.ora file.

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.
