It's time for our Mule Meet up in Reading (Virtual). Two interesting and informative topics are on the agenda.
Topic 1
Transaction management in MuleSoft
In a nutshell, a transaction is a group of actions that should be performed as one 'bulk action'. During this session, we will discuss how we can achieve it by using connectors, scopes, and exception handlers.
Topic 2
How to automate issue fixing in MuleSoft?
The presentation will discuss how the identified issues can be fixed in an automated manner, resulting in huge time & cost savings, code standardization, etc.

7. What is a Transaction?
Transaction is a group of actions that should be performed as if they were a single "bulk" action.
● Atomicity
● Consistency
● Isolation
● Durability

8. Transaction Management in Mulesoft
Transactions in Mule are required when we have a series of processes in a flow that must succeed
completely or fail completely.
8
9. Single Resource Transactions
It only uses a single resource to send or receive messages: JMS broker, VM queues, or JDBC connections.
○ The example below illustrates a flow which includes a single resource transaction performed using the source
and publish operations of the JMS connector.
9
13. XA Transactions
Extended Architecture Transactions (or XA Transactions) can be used to group a series of operations from multiple
transactional resources, such as VM, JMS or Database, into a single reliable global transaction.
The XA protocol defines a 2-phase commit protocol which can be used to reliably coordinate and sequence a series
of atomic operations across multiple servers of different types.
13
19. Using Bitronix to Manage Transactions
Bitronix works on JTA (Java Transaction API) to perform global transactions , that is, transactions that access and
update data on two or more networked computer resources.
Bitronix Transaction Manager allows Mule to automatically recover interrupted transactions on restart.
It runs a recovery process to process any inflight transactions that were left abandoned during a instance crash or
connectivity issues.
19
20. Error Handling
When an error occurs during a transaction, your application must either handle the error and continue or perform a
rollback.
There are two types of error handlers, which behave differently when an error occurs during a transaction:
○ On Error Propagate
○ If the on-error-propagate error handler is inside the error-handler scope corresponding to the
component that began the transaction it will rollback the transaction if there is any error in the flow.
20
21. Error Handling
On Error Continue
The error is handled, the transaction remains active and is able to commit.
21
22. Use Case : Ecommerce Checkout
The upcoming use case is about a ecommerce checkout and payment process involving payment through
multiple payment methods (wallet and bank transactions), gift cards redemption and cash back.
Requirements:
➔ Debit customer’s wallet and account based on the chosen payment method.
➔ If wallet debit or bank call times out , retry the entire transaction again in the background and create the
order for the customer
➔ If wallet debit or bank call returns any error, rollback the transaction and return the error message.
➔ If redemption of the gift card or credit of wallet fails, retry in the background and commit the transaction.

Mule-Sonar-Plugin
Mule-Sonar-Plugin is open source unlicensed project available in market which provides static code
analysis for Mulesoft projects. It leverages popular CQA platform SonarQube’s quality gates to do
validation of Mule code.
⮚ Open Source
⮚ No cost – free to use
⮚ Can scan multiple projects
⮚ Central view
⮚ Unlicensed – Not an official product.
⮚ Only static code analysis.
⮚ No plugin for Anypoint Studio
⮚ Comes with very few predefined Mule validation rules.
⮚ No thought leadership behind.
⮚ Since unlicensed – No support channel,
No guaranteed updates
Pros Cons

Quiz: Questions
1. In case there is no error handling defined and any failure happens during the
transaction, is the transaction rolled back or still committed?
2. Is it possible to set a transactional resource to skip and to not be a part of an in-
progress transaction ?
3. Does Munit support Sonar reports in Mule? If yes, with which version of Munit this
functionality was released? If not, what is the MuleSoft roadmap for this.

Quiz: Answers
1. In case there is no error handling defined and any failure happens during the
transaction, is the transaction rolled back or still committed?
Transaction is rolled back. By default, Mule propagates an exception in the absence of
exception handling
2. Is it possible to set a transactional resource to skip and to not be a part of an in-
progress transaction ?
Yes, it is possible if we explicitly set the transaction action as “Not_Supported“
3. Does Munit support Sonar reports in Mule?
1. If yes, with which version of Munit this functionality was released?
Yes, it does.
2. If not, what is the MuleSoft roadmap for this.
MuleSoft has already included this and it is available from Munit version 2.3.0
onwards.
