What is XA and non-XA transactions?
An XA transaction is a ‘global transaction’ that may span multiple resources, whereas a non-XA transaction always involves just one resource. An XA transaction involves a coordinating transaction manager, with one or more resources (databases\JMS) all involved in a single global transaction.
What is XA driver?
An XA driver can guarantee atomicity of updates across multiple participating resources. Two things are required: Configuration settings and application code. XA transaction support requires two configuration steps: Change the Connection Pool driver to use an XA Driver.
What is XA transaction?
XA is a two-phase commit protocol that is natively supported by many databases and transaction monitors. It ensures data integrity by coordinating single transactions accessing multiple relational databases.
What is a XA datasource?

What is XA in JTA?
JTA/XA is a kind of system insurance against data corruption (and the resulting business losses). The most common use cases are: Processing JMS messages from a queue and inserting the results in a database: you don’t want a crash to lose messages whose results are not yet stored in the database.
What is XA transaction in Mulesoft?

What are XA transactions in mysql?

What is XA JDBC?
The JDBC XA distributed transaction management classes enable you to use the IBM® Toolbox for Java™ JDBC driver within a distributed transaction. Using the XA classes to enable the IBM Toolbox for Java JDBC driver allows it to participate in transactions that span multiple data sources.
What are transactions mule4?
Transactions are operations in a Mule app for which the result cannot remain indeterminate. When a series of steps in a flow must succeed or fail as one unit, Mule uses a transaction to demarcate that unit.
What is polling in mule?
