•

Non Reclaimable Space Percent

The percentage, within the flashback area, of non-reclaimable space (space currently in use, which cannot be reclaimed).

Number of Files

Indicates the number of files currently stored on the flashback area.

Used Space Percent

The percentage of used space within the entire disk space allocated to the flashback area.

History Locks Tree Instance

The History Locks Tree Instance collection collects snapshots of instance-level locks that reached or exceeded the minimal duration, in seconds, required for collecting the lock. All locks that meet this criterion are displayed in the lower section of the Locks Historical Tree pane.

Metric Descriptions

The SQL statement that waits for lock release

Blocked SQL Hash

The hash value of the statement waiting for lock

Blocking Serial

Serial number of the locking session

A SID that holds locks

The name of the computer where the client is running

Indicates whether the global lock and the locking and blocked sessions are running on different RAC nodes (True) or not (False)

The Oracle database account of the started session

The name of the host where the instance is installed

Instance name of the session in the lock tree

The number of seconds the lock is running

The wait event on which the blocked statement is waiting

The lock mode in which the session holds the lock.

The lock mode can have one of the following values:

•

•

1 - null (NULL)

•

•

•

•

5 - S/Row-X (SSX)

•

6 - exclusive (X)

Lock Request Mode

The lock mode in which the process requests the lock.

The lock request mode has the same possible values as the lock mode.

The type of user or system lock.

The locks on the user types are obtained by user applications. Any process that is blocking others is likely to be holding one of these locks.

The user type locks are as follows:

•

TM - DML enqueue

•

TX - Transaction enqueue

•

UL - User supplied

The object on which the statement is blocked

The operating system user for the Client

In multitenant architectures, the name of the pluggable database.

The operating system process ID for the Oracle server process

The server program name

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

The session identification number
