Receive Queue

Use the controls on this page to set the size for how many queued receives to hold in memory to reduce the number of queries to the database. Sizing depends on server memory constraints.
The information on this page is as follows:
Unmatched Correlated Receive Timeout
The amount of time (in seconds) that the engine waits for a correlated message to be matched to a receive activity. This is only if the message arrives before the activity becomes active. If a correlated message takes longer than the specified time to be matched, the engine discards the message and you see a correlation violation exception
The default value is 30 seconds. To avoid many unconsumed messages on the server, set this value to a low number. If you set this value to specify zero seconds, the engine discards all unmatched correlated messages immediately.
When you click the Clock icon, you see the duration-chooser dialog box.
For more details, see Server Properties.
Unmatched Correlated Receive Count
The maximum number of unmatched correlated receives the engine will hold in memory at a time. When this limit is crossed, the engine rejects unmatched correlated receives; starting from the oldest, to make room for newer receives.
Queued Receive Cache Size
The size of the cache memory that holds activity information when the system is busy with other requests.
You can also change any of the values displayed for these three fields.
If events are displayed, select a receive and then select a partner link to view details. A window opens where you can see the BPEL process location in which the receive activity executes. You can also see the correlation property alias and data, if any, associated with this receive activity
