19 Oracle Forms

There are various metrics which can be used to monitor Oracle Forms Services.

Jvm Controllers

The JVM Controllers category provides information about all the JVM controllers. The following table lists the metrics and their descriptions.

Table 19-1 Jvm Controllers Metrics

Metric	Description
Classpath	Classpath of this JVM Controller
CPU	This metric is calculated from the total amount of CPU utilized by this Forms JVM controller
Forms Sessions	Number of Forms sessions this JVM Controller is handling
JVM Options	JVM options this JVM controller was started with
JVMs	Number of JVMs this JVM controller is handling
Logfile	Location of the logfile for this JVM controller
Logging	Specified whether the Logging is turned on or off for this JVM controller
Max Processes	maximum number of Forms Runtimes Processes this JVM controller can service before creating a child JVM
Private Memory	This metric is calculated from the total amount of private memory used by this Forms JVM controller
Start Time	Start time of this JVM controller

Jvm Load

The JVM Load category provides information about the present Load generated by the Forms JVM processes. The following table lists the metrics and their descriptions.

Table 19-2 Jvm Load Metrics

Metric	Description
Total CPU (%)	This metric is calculated from the total amount of CPU being used by all the Forms JVM processes. By default, the thresholds for this metric is not defined. The value for the thresholds can be edited as required.
Total Memory	This metric is calculated from the total amount of private and shared memory being used by all the Forms JVM processes.
Total Private Memory	This metric is calculated from the total amount of private memory being used by all the Forms JVM processes.
Total Shared Memory	This metric is calculated from the total amount of shared memory being used by all the Forms JVM processes.

Load

The Load category provides information about the present Load generated by Forms processes.

Total CPU (%)

This metric is calculated from the total amount of CPU being used by all the Forms processes. By default, the thresholds for this metric are not defined The value for the thresholds can be edited as required.

Metric Summary

The following table shows how often the metric's value is collected and compared against the default thresholds. The 'Consecutive Number of Occurrences Preceding Notification' column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

Table 19-3 Metric Summary Table

Target Version	Evaluation and Collection Frequency	Upload Frequency	Operator	Default Warning Threshold	Default Critical Threshold	Consecutive Number of Occurrences Preceding Notification	Alert Text
All Versions	Every Minute	After Every 12 Samples	>	Not Defined	Not Defined	1	CPU Utilization is %value%%%

Data Source

The value of this metric is calculated using operating system specific commands.

Total Memory (%)

This metric is calculated from the total amount of private and shared memory being used by all the Forms processes.

By default, this metric has a critical threshold of 90 and a warning threshold of 80. A critical alert is generated when the metric value exceeds the critical threshold value 1 time. A warning alert is generated when the metric value exceeds the warning threshold value 1 time. The value for the thresholds can be edited as required.

Metric Summary

The following table shows how often the metric's value is collected and compared against the default thresholds. The 'Consecutive Number of Occurrences Preceding Notification' column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

Table 19-4 Metric Summary Table

Target Version	Evaluation and Collection Frequency	Upload Frequency	Operator	Default Warning Threshold	Default Critical Threshold	Consecutive Number of Occurrences Preceding Notification	Alert Text
All Versions	Every Minute	After Every 12 Samples	>	80	90	1	Memory Utilization is %value%%%

Data Source

The value of this metric is calculated using operating system specific commands.

Total number of users

This metric reports the total number of Forms sessions being monitored by Enterprise Manager.

Metric Summary

The following table shows how often the metric's value is collected.

Target Version	Collection Frequency
All Versions	Every Minute

Data Source

This value of this metric is based on the number of Forms processes executing on the host. The current value of this metric can also be seen under Response and Load on the Forms Overview Page.

Response

The Response category provides information about the responsiveness of the Forms Servlet.

ResponseTime(ms)

This metric displays the response time in milliseconds for the Oracle Forms Servlet.

By default, this metric has a critical threshold of 1000 and a warning threshold of 500. A critical alert is generated when the metric value exceeds the critical threshold value 1 time. A warning alert is generated when the metric value exceeds the warning threshold value 1 time. The value for the thresholds can be edited as required.

Metric Summary

The following table shows how often the metric's value is collected and compared against the default thresholds. The 'Consecutive Number of Occurrences Preceding Notification' column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

Table 19-5 Metric Summary Table

Target Version	Evaluation and Collection Frequency	Upload Frequency	Operator	Default Warning Threshold	Default Critical Threshold	Consecutive Number of Occurrences Preceding Notification	Alert Text
All Versions	Every Minute	After Every 12 Samples	>	500	1000	1	The Forms Listener response time is unacceptable.

Data Source

The value of this metric is obtained by measuring the response to the Servlet URL shown on the Forms Overview Page.

Status

By default, this metric has a critical threshold of 0 indicating that the Forms Servlet is unreachable. A critical alert is generated when the metric value equals the critical threshold value once. It is advisable that this threshold be left at the default value.

Metric Summary

The following table shows how often the metric's value is collected and compared against the default thresholds. The 'Consecutive Number of Occurrences Preceding Notification' column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

Table 19-6 Metric Summary Table

Target Version	Evaluation and Collection Frequency	Upload Frequency	Operator	Default Warning Threshold	Default Critical Threshold	Consecutive Number of Occurrences Preceding Notification	Alert Text
All Versions	Every Minute	After Every 12 Samples	=	Not Defined	0	1	The Forms instance is not accessible.

Data Source

The value of this metric is obtained by measuring the availability of the Servlet URL shown on the Forms Overview Page. The current value of this metric can also be seen under Response and Load on the Forms Overview Page.

User Action

Check whether the OC4J_BI_Forms oc4j instance has been started and if so that the application forms90app.ear has been deployed successfully.
