Reviewing Instance Usability

The Instance Usability panel displays aggregated information regarding the instance’s usability and availability.

This panel supports the following tasks:

•	Identifying instances. For details, see The Instance Pane .

•	Viewing usability-related alarms. For details, see The Alarms Pane .

•	Tracking the instance’s availability, plotted over the defined time range. For details, see The Instance Availability Section .

•	Tracking the listener’s availability, plotted over the defined time range. For details, see The Listener Availability Section .

•	Tracking the instance’s connection time, plotted over the defined time range. For details, see The Connection Time Section

•	Tracking the instance’s response time, plotted over the defined time range. For details, see The Response Time Section .

The Instance Pane

The Instance pane contains the following indicators:

•	DB Type — identifies monitored database’s type (for example: SQL Server or Oracle).

•	Oracle Version — identifies the Oracle version number, along with the most recently installed patches.

•	Up Since — identifies the date and time when the instance was last started. If the database is not running this area reads “Database is down”, and a popup is available, displaying the database status.

The Alarms Pane

The Alarms pane displays the usability-related outstanding alarms. These alarms alert the following issues per instance: response time, instance availability, instance connection availability, OS connection availability, instance connection time, and Listener status.

The Instance Availability Section

The Instance Availability section displays the instance availability in percentages, plotted over the time range. If the instance was unavailable once or more during this time, the relevant message describing the last occurrence of unavailability appears in the Error Message box.

The Listener Availability Section

The Listener Availability section displays the availability of all listeners configured for the instance, in percentages, plotted over the time range. If one or more of the listeners were unavailable during this time, a message describing this issue appears under the Listener Errors section.

The Connection Time Section

The Connection Time section displays the instance’s connection time, in seconds, plotted over the time range.

The Response Time Section

The Response Time section displays the instance’s response time, in milliseconds, plotted over the time range.

Reviewing Cluster Usability

Use the Cluster Usability panel to compare between the various RAC nodes, regarding the following indicators:

•	Availability — measured in percentages

IMPORTANT: The Availability section also displays the listener’s availability during the specified time range.

•	Connection Time — measured in milliseconds

•	Response Time — measured in milliseconds

 

To investigate a single instance, select the requested instance from the list at the top of the panel. The display switches to instance usability. For details, see Reviewing Instance Usability .

Reviewing Locks Activity at the Cluster Level

The Activity Locks panel for a RAC comprises the following panes:

•	Locks Activity

•	Lock Tree (Current)

•	Locks Historical Tree

Locks Activity

The Locks Activity pane displays a breakdown of all lock types and their general properties.

 

Table 9. Locks Activity pane

Name	Description
Lock Name	The name of the lock.
Gets	The total number of enqueue requests or enqueue conversions for this type of enqueue.
Gets Rate	The rate of lock gets.
Gets (percent)	The percentage of lock gets for this type of lock within the total number of locks.
Enqueue Waits	The total number of times an enqueue request or conversion resulted in a wait event.
Waits Rate	The number of wait events per second.
Wait (percent)	The percentage of wait events for this type of lock within the total number of locks.
Lock Wait	The total amount of time spent waiting for the enqueue or enqueue conversion.
Average Lock Duration	The average length of time for a lock, in milliseconds.
Lock Efficiency	The percentage of lock requests that did not escalate to a blocking lock.
Alarms	The number of warning, critical, and fatal alarms that were invoked for this Oracle database instance. Holding the cursor over each alarm type displays a dwell that shows the most recent alarms invoked for this database instance, sorted by severity. Click each alarm type to drill down and manage the alarms. See the Foglight Online Help, Monitoring System-Wide Alarms for details on the alarm information.

Lock Tree (Current)

The Lock Tree (Current) pane displays current data, which is available only in real-time mode.

Clicking any locking or locked session table row displays a popup that is used for viewing further details. For information see Session Details Popup .

 

Table 10. Lock Tree (Current)

Name	Description
PDB	In multitenant architectures, the name of the pluggable database where the lock took place.
Session	The identifier for a session that holds or acquires the lock.
Serial	The session’s serial number. The combination of SID and serial number provides a unique identification of the session.
DB User	The database user name.
Object Wanted	The object requested for lock.
Lock Type	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: • TM — DML enqueue • TX — Transaction enqueue • UL — User supplied
Lock Mode	The lock mode in which the session holds the lock. This row can have one of the following values: • None • Null • Row-S (SS) • Row-X (SX) • Share • S/Row-X (SSX) • Exclusive
Lock Request Mode	The lock mode in which the process requests the lock. This row can have one of the values listed below. • None • Null • Row-S (SS) • Row-X (SX) • Share • S/Row-X (SSX) • Exclusive
Lock Duration	The duration of the lock in seconds.
Cross Instance	Defines whether the lock is between different cluster nodes: • YES — for global locks • NO — for single node locks
Instance	The name of the instance to which the blocking or blocked session belongs.
Kill Session	Used for terminating the selected session, by means of the Kill Session dialog box that is displayed upon clicking this column. NOTE: Killing a session requires having specific privileges. Please provide an Oracle user with these privileges. Alternatively, select the check box Log-in as SYSDBA to provide the credentials of a SYSDBA user.

Session Details Popup

 

Table 11. Session Details Popup

Name	Description
SID	The session identifier
Serial	The session’s serial number. The combination of SID and serial number provides a unique identification of the session.
Process	The process number
DB User	The database user name
OS	The operating system name
Program	The name of the program that is processing the SQL statements
Client	The Client computer identifier
Host	The host computer identifier
Current SQL	The SQL text of the SQL statement that is currently being processed in this session

Locks Historical Tree

The Locks Historical Tree pane displays the overall locks activity that took place within the selected time range, as well as locks that exceeded a predefined threshold.

This pane comprises the following sections:

•	Lock Wait Events — a chart that displays all of the lock wait events, plotted over time. This chart can be viewed in either of the following views:

•	Baseline — displaying only lock wait events.

•	Breakdown — displaying both lock and non-lock wait events.

•	Locks Exceeding a predefined threshold — displays locks that reached or exceeded the minimal duration, in seconds, which a lock should reach or exceed in order to be collected.

NOTE: The minimal duration’s length is defined using the Locks pane of the Collection Settings view.

Reviewing Locks Activity at the Instance Level

The Activity Locks panel, which displays lock summary information for an Oracle instance, comprises the following panes:

•	Locks Wait Events chart

The content of this pane is similar to that of the chart displayed under the Activity > Locks > Locks Historical Tree pane at the Whole Cluster mode. For more information, see Locks Historical Tree.

•	Locks Activity pane — identical to the Locks Activity pane in the Whole Cluster mode. For more information, see Locks Activity.

•	Locks Tree (Current) pane — identical to the Locks Tree (Current) pane in the Whole Cluster mode. For more information, see Lock Tree (Current).

•	Locks Historical Tree — see Locks Historical Tree .
