Session serial number. Used to identify uniquely a session's objects. Guarantees that session-level commands are applied to the correct session objects if the session ends and another session begins with the same session ID.
Auditing session ID
RAW(4 | 8)
Address of the process that owns this session
Oracle user identifier
Command in progress (last statement parsed); for a list of values, see Table 3-3. These values also appear in the AUDIT_ACTIONS table.
The column contents are invalid if the value is 2147483644. Otherwise, this column contains the identifier of the user who owns the migratable session.
For operations using Parallel Slaves, interpret this value as a 4-byte value. The low-order 2 bytes of which represent the session number, and the high-order bytes the instance ID of the query coordinator.
Address of transaction state object
Address of lock waiting for; NULL if none
Status of the session: ACTIVE (currently executing SQL), INACTIVE, KILLED (marked to be killed), CACHED (temporarily cached for use by Oracle*XA), SNIPED (session inactive, waiting on the client)
Server type (DEDICATED| SHARED| PSEUDO| NONE)
Schema user identifier
Schema user name
Operating system client user name
Operating system client process ID
Operating system machine name
Operating system terminal name
Operating system program name
Used with SQL_HASH_VALUE to identify the SQL statement that is currently being executed
Used with SQL_ADDRESS to identify the SQL statement that is currently being executed
Used with PREV_HASH_VALUE to identify the last SQL statement executed
Used with SQL_HASH_VALUE to identify the last SQL statement executed
Contains the name of the currently executing module as set by calling the DBMS_APPLICATION_INFO.SET_MODULE procedure
The hash value of the above MODULE
Contains the name of the currently executing action as set by calling the DBMS_APPLICATION_INFO.SET_ACTION procedure
The hash value of the above action name
Information set by the DBMS_APPLICATION_INFO.SET_CLIENT_INFO procedure
This contains a number that increases every time the session completes a call to the database and there has been an intervening select from a dynamic performance table. This column can be used by performance monitors to monitor statistics in the database. Each time the performance monitor looks at the database, it only needs to look at sessions that are currently active or have a higher value in this column than the highest value that the performance monitor saw the last time. All the other sessions have been idle since the last time the performance monitor looked at the database.
Object ID for the table containing the ROWID specified in ROW_WAIT_ROW#
Identifier for the datafile containing the ROWID specified in ROW_WAIT_ROW#. This column is valid only if the session is currently waiting for another transaction to commit and the value of ROW_WAIT_OBJ# is not -1.
Identifier for the block containing the ROWID specified in ROW_WAIT_ROW#. This column is valid only if the session is currently waiting for another transaction to commit and the value of ROW_WAIT_OBJ# is not -1.
The current ROWID being locked. This column is valid only if the session is currently waiting for another transaction to commit and the value of ROW_WAIT_OBJ# is not -1.
Time of logon
The last call
This column has been replaced by column PDML_STATUS
Indicates whether and to what extent transparent application failover (TAF) is enabled for the session:
NONE - failover is disabled for this session
SESSION - the client is able to fail over its session following a disconnect
SELECT - the client is able to fail over queries in progress as well
Oracle9i Database Concepts for more information on TAF
Oracle9i Net Services Administrator's Guide for information on configuring TAF
Indicates the transparent application failover method for the session:
NONE - failover is disabled for this session
BASIC - the client itself reconnects following a disconnect
PRECONNECT - the backup instance can support all connections from every instance for which it is backup
Indicates (YES|NO) whether the session is running in failover mode and failover has occurred
Name of the session's current resource consumer group
If ENABLED, the session is in a PARALLEL DML enabled mode. If DISABLED, PARALLEL DML enabled mode is not supported for the session. If FORCED, the session has been altered to force PARALLEL DML.
If ENABLED, the session is in a PARALLEL DDL enabled mode. If DISABLED, PARALLEL DDL enabled mode is not supported for the session. If FORCED, the session has been altered to force PARALLEL DDL.
If ENABLED, the session is in a PARALLEL QUERY enabled mode. If DISABLED, PARALLEL QUERY enabled mode is not supported for the session. If FORCED, the session has been altered to force PARALLEL QUERY.
If queued (1), the current amount of time the session has been queued. If not currently queued, value is 0.
