What is difference between XA datasource and non-XA data source?
An XA transaction, in the most general terms, is a “global transaction” that may span multiple resources. A non-XA transaction always involves just one resource.
What is XA and non-XA in WebLogic?
An XA transaction involves a coordinating transaction manager, with one or more resources (databases\JMS) all involved in a single global transaction. Non-XA transactions have no transaction coordinator, and a single resource is doing all its transaction work itself (also called local transactions).
What is non-XA datasource?
A non-XA data source is also known as a 1pc (one phase commit) data source. An XA data source is also known as a 2pc (two phase commit data source). A 1pc data source can be included in a transaction with 2pc data sources as long as you use the Last Participant Support (LPS) for the 1pc data source.
What is a XA data source?
An XA datasource is used instead of the datasource if the target Jboss application: Uses the Java Transaction API (JTA) Includes multiple database updates within a single transaction. Accesses multiple resources, such as a database and the Java Messaging Service (JMS), during a transaction.
How do I create a non XA data source in Weblogic?
1) Login to Weblogic server console using http://:7001/console. 3) You will view the below screen. 4) In order to enable the ‘New’ button click on the ‘Lock & Edit’ button under ‘Change Center’ on the top left corner. 8) Now you need to add this Data source (jamesxedb) in the DBAdapter connection pool.
What is XA resource?
The XAResource interface is a Java mapping of the industry standard XA interface based on the X/Open CAE Specification (Distributed Transaction Processing: The XA Specification).
What is multi datasource in WebLogic?
A multi data source is an abstraction around a group of data sources that provides load balancing or failover processing between the data sources associated with the multi data source. Multi data sources are bound to the JNDI tree or local application context just like data sources are bound to the JNDI tree.
What is the difference between connection pool datasource and XA datasource in Websphere?
XA Data Source– its a data source where applications requires double phase commit transaction. connection pool data source– where applications require single phase commit transactions.
What is the use of XA datasource Jboss?
What is XA transaction in SOA?
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 XA support?
What is XA transaction in Oracle?
The XA standard is an X/Open specification for distributed transaction processing (DTP) across heterogeneous data sources (e.g. Oracle Database and DB2) that was published in 1991. It describes the interface between the transaction coordinator and the data sources that participate in the distributed transaction.
What is GridLink data source in WebLogic?
What is a GridLink Data Source. A single GridLink data source provides connectivity between WebLogic Server and an Oracle Database service targeted to an Oracle RAC cluster. It uses the Oracle Notification Service (ONS) to adaptively respond to state changes in an Oracle RAC instance.
What is the difference between xa and non-Xa DataSource?
A non-XA datasource generally can’t participate in a global transaction (sort of – some people implement what’s called a “last participant” optimization that can let you do this for exactly one non-XA item). An XA transaction, in the most general terms, is a “global transaction” that may span multiple resources.
What is XA transaction in JMS?
An XA transaction, in the most general terms, is a “global transaction” that may span multiple resources. An XA transaction involves a coordinating transaction manager, with one or more databases (or other resources, like JMS) all involved in a single global transaction.
Can an XA DataSource run multiple transactions in one transaction?
An XA datasource is not the solution to make them run in one transaction. Instead, you should both let them use the same connection and transaction. XA transactions are really only useful if you are using multiple database systems or other systems, and you want to be able to perform transactions that span across these systems.
What is an XA DataSource in WildFly?
An XA DataSource is a particular DataSource that participates in an XA global transaction. WildFly supports it through Ironjacamar, the official JCA resource adapter implementation and Narayana, the transaction manager implementation in WildFly.
