The MicroTx PL/SQL library provides the following functions to specify the transaction boundaries.

• TMM_BEGIN_TX Function
  Used by a transaction initiator application to start a global transaction that spans across multiple microservices. It returns a MicroTxTransaction object which has the transaction metadata.
• TMM_GET_TX_STATUS Function
  Used by a transaction initiator application to retrieve the current transaction status.
• TMM_COMMIT_TX Function
  Used by the transaction initiator application to commit a global transaction.
• TMM_ROLLBACK_TX Function
  Used by a transaction initiator application to roll back a global transaction.
• TmmStart Function
  Enlists the transaction participant service with the MicroTx XA coordinator in a global transaction, starts the XA transaction boundary, registers the call back REST APIs, and returns the transaction metadata.
• TmmEnd Function
  Call the TmmEnd function in your participant application code after the business logic has been completely executed. It ends the XA transaction boundary.
