12.4 Response

This category contains the response metrics for Oracle BPEL Process Manager.

12.4.1 UpDown Status

This metric shows whether Oracle BPEL Process Manager is up or down. If the value is 1, Oracle BPEL Process Manager is up. If the value is 0, it is down.

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 12-4 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 Sample	<	Not Defined	1	1	Not Defined

User Action

If the Oracle BPEL Process Manager is down, restart it using the Home page for the J2EE container (OC4J_BPEL) in which Oracle BPEL Process Manager is deployed.
