A retry policy is required to specify the number of retries,
retry interval, and other retry settings. The settings in the retry
policy are used to redeliver a message when the first delivery attempt
fails.
Before you begin
Retries are performed in the following situations:
- The destination is not available (for example, if your trading partner's server is down)
- The destination is unreachable (for example, if the URL or port is invalid)
- An SSL failure occurred
- A certificate issue occurred (for example, if the certificate is invalid)
Restriction: If the data is transmitted and the data transfer is broken, retry is not
performed.
You also can import a retry policy as
a resource from another installation of AS4 Microservice.
For more information, see ../reference/as4/meg_resource_commands.html.
About this task
To create a retry policy, complete
the following procedure:
Procedure
- Log in to the AS4 Microservice user
interface.
- Click Systems Management and select Retry
Policies.
- On the Retry Policies page, click New.
- On the New Retry Policy page, specify
values for the following fields:
| Field |
Description |
Name
|
Type a unique name for the retry policy.
|
Description
|
Optional: Type a description for the retry
policy.
|
Number of server retries
|
Server retries correspond to the transport
level retry. A transport level retry is made to resolve the transient
failures in the network over which delivery is attempted.
If
a failure occurs at the transport level, specify the number of times
you want AS4 Microservice to
retry to deliver the document.
|
Server retry interval
|
Specify the time interval for the server retry,
and select the required unit of time. Available options are:
- seconds (default)
- minutes
|
Number of destination retries
|
A destination retry is specific to a particular
HTTP or HTTPS destination.
Specify the number of times you want AS4 Microservice to
try to deliver the document if the specified HTTP or HTTPS destination
is not available.
Minimum number of retries must be 1.
|
Destination retry interval
|
Specify the time interval for destination
retry. Select the required unit of time. Available options are:
- seconds (default)
- minutes
|
Automatic queue settings
|
Optional: Select the check box to queue the delivery requests when the target service (AS4) or
the trading partner destination is not available.
Note: If automatic queue
is enabled in the retry policy and if a message cannot be delivered
to a destination after all the retries are exhausted, the HTTPS or
MDN destination is disabled. The reason is to stop the store and forward
service from sending messages to the destination that is down. In
this case, you must enable the destination by selecting the Enable
destination check box in the HTTPS or MDN destination
configuration user interface.

- Click Save to save the retry policy.
The new retry policy is listed on the Retry Policies page.
