How to Get Here

To open the Instance home page, from the Databases dashboard, find the instance you want to explore and click the instance name (or click and select Overview). The Databases > Overview dashboard opens with a summary of the selected instance.

From here, you can drill down to metrics on memory allocation and perform configuration tasks.

The following summary and drill-downs pages are provided:

Configuration Drill-down (links to description under Database home page)

Summary

By default, the Summary page view is displayed on the Instance home page. The Summary page contains the following embedded panes:

The Status pane displays metrics that provide an overview of the current state of the DB2 instance. It is at the top of the Instance home page.

Sessions (no.). The total number of active and inactive sessions within the instance.

 

CPU (%). Total is the average CPU usage of all the underlying hosts on which the instance resides. DB2 is the total CPU usage by all DB2 processes running on the host.

 

Memory (%). Total is the average memory usage of all the underlying hosts on which the instance resides. DB2 is the total memory usage by all DB2 processes running on the host.

 

Instance Information. The configuration information for the instance (including the product version and whether the product is licensed). Click the icon for the configuration information.

 

Active Databases. The total number of local databases within the instance that have applications connected.

 

Active Members. The total number of active members within the instance.

 

Up since. The date and time the instance was started.

 

Status. Whether the instance is active.

 

Availability. The current availability of the instance.

 

pureScale only Active Members. Number of nodes in the pureScale environment.

 

pureScale only Active CF. Displays information about configured CF nodes and their states.

 

pureScale only pureScale Alerts. Total number of alerts DB2 reported on the pureScale environment.

The Storage pane provides current storage information for the entire instance. It is at the left of the Instance home page.

 

Fixed storage. The total disk space that is available for use by fixed-size tablespaces and the disk space that is still free to be used by fixed-size tablespaces.

 

Auto storage. The total file system space that is available for the instance to use to carry out auto storage tablespace operations. Also, the file system space that is still free for the instance to use to carry out auto storage tablespace operations.

Clicking the icon below either of the charts displays a pop-up that provides additional, related information.

The Agents pane provides registered and stolen agents information for the entire instance. It is located in the middle of the Instance home page.

 

Agents Registered. Displays the current agents registered to the instance, and the average agents registered to the instance over the course of the selected time range.

 

Agents Stolen. Displays the current agents stolen from the instance, and the average agents stolen from the instance over the course of the selected time range.

Clicking the icon next to either of the metrics displays a pop-up that provides additional, related information.

The FCM pane displays FCM metrics for a partitioned instance. It is at the left and in the middle of the Instance home page.

 

FCM Sent (page/s). The total number of FCM buffer pages sent from the current node to the remote node, over the course of the selected time range.

 

FCM Received (page/s). The total number of FCM buffer pages received by the current node from the remote node, over the course of the selected time range.

Clicking the icon next to either of the metrics displays a pop-up that provides additional, related information.

When an instance is hosted in a DB2 pureScale environment, you can click the pureScale CF link to see metrics about the cluster cache facility (CF).

Current Primary ID. The ID of the CF component.

 

CPU Usage. Percentage of overall CPU usage on the CF machine.

 

Current Host. The current host of the selected DB2 instance. In a pureScale environment, the host can change depending on load.

 

Memory Utilization. Percentage of overall memory usage on the CF component.

Clicking the icon next to either of the metrics displays a pop-up that provides additional, related information.

The Reports pane provides access to the Executive Workload Summary Report, which is a workload overview of the instance and of each database. It is at the bottom left of the Instance home page.

Click the Executive Summary Report link to access the report.

The History pane displays the instance activity over the course of the selected time range. It is at the upper right of the Instance home page.

Top Database Workload. The top three (if available) database workloads, over the course of the selected time range.

 

Top Database Request Time. The top three (if available) database total request times and wait request times, over the course of the selected time range.

The Alarms pane displays the total number of fatal, critical, and warning alarms that are currently outstanding against the instance. It is at the lower right of the Instance home page.

Data displayed

Fatal. The total number of fatal alarms that are currently outstanding against the instance.

 

Critical. The total number of critical alarms that are currently outstanding against the instance.

 

Warning. The total number of warning alarms that are currently outstanding against the instance.

Clicking either of the three numbers opens the Outstanding Alarm(s) dialog box, which provides a list of the outstanding alarms and a brief description of each.

Clicking any of the rows in the Outstanding Alarm dialog box opens the Alarm dialog box, which provides detailed information about the associated alarm.

Memory Drill-down

The Memory view provides metrics on how the databases in the instance use memory.

On the Instance home page, click Memory.

This home page contains the following embedded views:

Primary CF tab (pureScale only)
Backup CF tab (pureScale only)

Shows how the total memory available for the instance is allocated to the database and CF pools.

DB Memory. Displays the total memory allocated to the selected instance and its databases in a stacking area chart. For pureScale environments, also shows primary and backup CF allocations.
Pool Breakdown. Displays the total memory allocated to the selected instance and its databases as a pie chart. For pureScale environments, also shows primary and backup CF allocations.

Shows where the instance gets its memory.

Instance Manager Memory. Displays the total memory available to the instance.
Pool Allocated Size. Displays the pools that contribute to the memory for the instance as a stacking area chart.
Instance Manager Breakdown. Displays the pools that contribute to the memory for the instance as a pie chart.
Pool Name. The name of the memory pool.
Utilization %. The percentage of configured allocated memory that is in use.
Allocation. The average allocated size (in KB) of a memory pool.
Config Size. The internally configured size (in KB) of a memory pool in the DB2 database system.
