16 Java EE Application

This chapter describes metrics for Java EE applications deployed to Oracle WebLogic Server.

16.1 ADFC Taskflow Metrics

Metrics concerning ADFc (ADF Controller)

16.1.1 Total Active Taskflows

The count of active task flows in an ADF application since the application was run. This metric records the number of times that a task flow has been the active task flow for a user.

For example, if the user goes from task flow A to task flow B and then exits back to A, then task flow A will have been active two times and task flow B active once. Therefore the total active count would be three.

16.23.2 State

This metric shows the current state of the application.

This metric specifies whether this application version is the currently active version. An application can be the only version currently deployed, or it can have more than one version currently deployed, using the side-by-side deployment feature.

If more than one version is deployed, only one version can be active.

Values for this metric can be:

  • INACTIVE - it has not been activated yet, or that there is more than one version of the application deployed (using side-by-side deployment) and this one is retiring.

  • ACTIVE_ADMIN - the currently active version for administrative channel requests.

  • ACTIVE state the currently active version for normal (non-administrative) channel requests.

This metric provides details on the unreferenced modules recycled.

16.25 MDS Metrics

Metrics concerning MDS (Metadata Services)

16.25.1 Metadata Object Gets Per Second

The number of metadata object gets per second.

Metric Summary

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

Target Version Collection Frequency
All Versions Every 5 Minutes

User Action

High values (100s or 1000s or more) may occur for a heavily used and/or complex application. No action needs to be taken unless application performance is perceived to be too slow, in which case it might be advisable to increase the hardware resources available to the application.

16.25.2 Metadata Object Get Processing Time (seconds)

The average elapsed time in seconds to get a metadata object.

Target Version Evaluation and Collection Frequency Upload Frequency Operator Default Warning Threshold Default Critical Threshold Alert Text
All Versions Every 5 Minutes After Every 3 Samples > Not Defined Not Defined The average processing time of each Metadata Object Get is %value% seconds.

User Action

This value should be considerably less than 1 second. If the value is greater than about 0.01, check the cache efficiency metrics (IOs Per Metadata Object Get and IOs Per MO Content Get), and increase the MDS cache size if those metrics indicate a problem. If those metrics are normal, the CPU may be overloaded, meaning the application may need more hardware resources, especially if performance is perceived to be slow.

16.25.3 IOs Per Document Get

The average number of physical IOs per persistence-level document get. This is an indication of the efficiency of the document cache portion of the metadata cache for the application. Ideally it should be much less than 1.

Target Version Evaluation and Collection Frequency Upload Frequency Operator Default Warning Threshold Default Critical Threshold Alert Text
All Versions Every 5 Minutes After Every 3 Samples > Not Defined Not Defined The average number of physical IOs per Document Get is %value%.

User Action

If the value is close to or more than 1, this could indicate that the MDS cache for the application is too small. Try increasing the size of the MDS cache to see if it reduces the value of this statistic.

16.25.4 IOs Per MO Content Get

The average number of physical IOs per metadata object XML content retrieval. This is an indication of the efficiency of the metadata cache for the application. Ideally it should be much less than 1.

Target Version Evaluation and Collection Frequency Upload Frequency Operator Default Warning Threshold Default Critical Threshold Alert Text
All Versions Every 5 Minutes After Every 3 Samples > Not Defined Not Defined The average number of physical IOs per MO Content Get is %value%.

User Action

If the value is close to or more than 1, this could indicate that the MDS cache for the application is too small. Try increasing the size of the MDS cache to see if it reduces the value of this statistic.

16.25.5 IOs Per Metadata Object Get

The average number of physical IOs per metadata object get. This is an indication of the efficiency of the metadata cache for the application. Ideally it should be much less than one.

Target Version Evaluation and Collection Frequency Upload Frequency Operator Default Warning Threshold Default Critical Threshold Alert Text
All Versions Every 5 Minutes After Every 3 Samples > Not Defined Not Defined The average number of physical IOs per Metadata Object Get is %value%.

User Action

If the value is close to or more than 1, this could indicate that the metadata cache for the application is too small. Try increasing the size of the MDS cache to see if it reduces the value of this statistic.

16.25.6 Metadata Updates Per Second

The average number of metadata objects updated per second.

Metric Summary

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

Target Version Collection Frequency
All Versions Every 5 Minutes

User Action

If the value of this metric is significant compared to the number of HTTP requests serviced per second, it means many users are creating or updating customizations or personalizations using the page composer or, more likely, via inherent changes. In this case, if application performance is perceived be slow, it might be wise to reduce the number of these updates by configuring the application to use a different ADF change manager (so the changes are saved in memory only, not to disk).

No user action.

16.25.7 Metadata Update Processing Time (seconds)

The average elapsed time in seconds taken to update a metadata object.

Target Version Evaluation and Collection Frequency Upload Frequency Operator Default Warning Threshold Default Critical Threshold Alert Text
All Versions Every 5 Minutes After Every 3 Samples > Not Defined Not Defined The average processing time of each Metadata Update is %value% seconds.

User Action

If the value of this metric exceeds about 1 second the MDS repository database may need tuning. If the "Metadata Updates Per Second" metric is also high, steps may need to be taken to reduce the number of updates (see user action for that metric).

16.25.8 Response

This category provides information about response metrics

16.25.9 UpDown Status

The up or down status of the application. A value of one (1) indicates that the application is up and running; a value of zero (0) indicates that the application is down.
