#### Advanced Parameters
NameTypeDescriptionDefault ValueRequired

Check for duplicate messages

Checks for duplicate messages:

  • If selected, the connector checks to see if a new received message is duplicated, as determined by comparing the following values in the new message to those in existing messages:

    • Sender (from the AS2-From field)

    • Receiver (from the AS2-To field)

    • Message ID (from the Message-Id field)

    If all three values match an existing message, the connector rejects the duplicate message. If selected, you must:

    • Reference a global object store in the Object Store field. This object store will store the existing messages.

    • Add the object store dependency to your project by adding the ObjectStore component to the Studio canvas or adding it to the pom.xml, as follows:

      <dependency>
  <groupId>org.mule.connectors</groupId>
  <artifactId>mule-objectstore-connector</artifactId>
  <version>_latest-version_</version>
  <classifier>mule-plugin</classifier>
</dependency>

      For the latest object store version, see the Object Store Connector Release Notes.

      If the MDN mode is AUTO, use the Idempotent Message Validator instead of the Check for duplicate messages field to check for duplicate messages. If the MDN mode is IMMEDIATE, the validator does not work. Therefore, in this circumstance, you must use the Check for duplicate messages field to check for duplicate messages. For more information, see Idempotent Message Validator.

    • If deselected, the connector accepts duplicate messages.

false

Object Store

Object Store

Object store where the connector stores new messages. This field is mandatory if the Check for duplicate messages field is selected.

For information about setting field values for this object store, see the Object Store Connector Reference.

You might experience limitations that are specific to the object store implementation you are using (Anypoint Object Store V2 (OSv2), CloudHub Object Store V1 (OSv1), or Mule Object Store), so configure the object store to suit your needs. For more information, see The Different Types of Object Stores Explained.

### Reconnect Configures a standard reconnection strategy, which specifies how often to reconnect and how many reconnection attempts the connector source or operation can make.
FieldTypeDescriptionDefault ValueRequired

Number

How often to attempt to reconnect, in milliseconds.

Reconnection Attempts

Number

How many reconnection attempts to make.

Blocking

Boolean

If false, the reconnection strategy runs in a separate, non-blocking thread.

true

### Reconnect Forever Configures a forever reconnection strategy by which the connector source or operation attempts to reconnect at a specified frequency for as long as the Mule app runs.
FieldTypeDescriptionDefault ValueRequired

Frequency (ms)

Number

How often to reconnect, in milliseconds

Blocking

Boolean

If false, the reconnection strategy runs in a separate, non-blocking thread.

true

### Reconnection Configures a reconnection strategy for an operation.
FieldTypeDescriptionDefault ValueRequired

Fails Deployment

Boolean

What to do if, when an app is deployed, a connectivity test does not pass after exhausting the associated reconnection strategy:

  • true: Allow the deployment to fail.

  • false: Ignore the results of the connectivity test.

Reconnection Strategy

The reconnection strategy to use.

### Redelivery Policy
FieldTypeDescriptionDefault ValueRequired

Max Redelivery Count

Number

The maximum number of times a message can be redelivered and processed unsuccessfully before triggering a process-failed message.

Use Secure Hash

Boolean

Whether to use a secure hash algorithm to identify a redelivered message.

Message Digest Algorithm

String

The secure hashing algorithm to use. If not set, the default is SHA-256.

Id Expression

### Repeatable File Store Stream
FieldTypeDescriptionDefault ValueRequired

In Memory Size

Number

Maximum amount of memory that the stream can use for data. If the amount of memory exceeds this value, Mule buffers the content to disk. To optimize performance:

  • Configure a larger buffer size to avoid the number of times Mule needs to write the buffer on disk.

    This increases performance, but it also limits the number of concurrent requests your application can process, because it requires additional memory.

  • Configure a smaller buffer size to decrease memory load at the expense of response time.

Buffer Unit

Enumeration, one of:

  • BYTE

  • KB

  • MB

  • GB

The unit in which the value of In Memory Size is expressed

### Repeatable In Memory Stream Configures the in-memory streaming strategy by which the request fails if the data exceeds the value of the **MAX Buffer Size** field. Always run performance tests to find the optimal buffer size for your specific use case.
FieldTypeDescriptionDefault ValueRequired

Initial Buffer Size

Number

Initial amount of memory to allocate to the data stream. If the streamed data exceeds this value, the buffer expands by Buffer Size Increment, with an upper limit of the In Memory Size value.

Buffer Size Increment

Number

This is by how much the buffer size expands if it exceeds its initial size. Setting a value of zero or lower means that the buffer should not expand, meaning that a STREAM_MAXIMUM_SIZE_EXCEEDED error is raised when the buffer gets full.

Max Buffer Size

Number

Maximum size of the buffer. If the buffer size exceeds this value, Mule raises a STREAM_MAXIMUM_SIZE_EXCEEDED error. A value of less than or equal to 0 means no limit.

Buffer Unit

Enumeration, one of:

  • BYTE

  • KB

  • MB

  • GB

Unit for the Initial Buffer Size, Buffer Size Increment, and Max Buffer Size fields.

### Standard Revocation Check
FieldTypeDescriptionDefault ValueRequired

Only End Entities

Boolean

Boolean

Do not use the secondary checking method, which is the method not specified in the Prefer Crls field.

Soft Fail

Boolean

Avoid verification failure when the revocation server cannot be reached or is busy.

### Success Status Code Validator
FieldTypeDescriptionDefault ValueRequired

Values

String

Comma-separated list of status codes that indicate success.

x

### TLS Configures TLS to provide secure communications for the Mule app.

Revocation Check

Configures a revocation checking mechanism.

### Truststore Configures the truststore for TLS.
FieldTypeDescriptionDefault ValueRequired

Path to the truststore. Mule resolves the path relative to the current classpath and file system.

Password

String

Password used to protect the truststore.

Type

String

Type of truststore.

Algorithm

String

Encryption algorithm used by the truststore.

Insecure

Boolean

If true, Mule stops performing certificate validations. Setting this field to true can make connections vulnerable to attacks.
