Segment Space Management

Indicates the method used for managing free and used segments:

•

manually — by free lists

•

automatically — by bitmaps

Metric Descriptions


Metric	Description
Action	The currently executing action name set by DBMS_APPLICATION_INFO.SET_MODULE
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

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.

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.
