Essential improvement of the DTC support

DTC - Distributed Transaction Coordinator.

DTC applies in:

MS SQL Linked Server uses DTC for synchronization the local transactions with linked server transactions.
The realization of the distributed transaction through the TransactionScope class in .Net Framework

For all IBProvider versions

Control improvement: Now if transaction is connected to DTC, it can not be finished through session methods (Commit or Rollback).
ITransaction::GetTransactionInfo. If the transaction is connected to DTC, the method returns UOW (UnitOfWork) identifier of the distributed transaction.
Two-phase commit was supported.

Two-phase commit (Two-phase transaction)

The Transaction commit has 2 phases:
Preparation phase - all the members of the distributed transaction are interrogated on commit end.

Commit phase - If all the members are ready to commit transaction, the coordinator sends the commit order.

It is guaranteed that all the members of the distributed transaction stay in agreed circumstances.

IBProvider v3

Additional control for commit the transaction connected to DTC through the SQL requests.

Summary

We constantly work to provide our clients with the reliable, functional and general-purpose decision that lets realize any projects on Firebird and Interbase.

The new release is one more possibility to feel the whole power of modern development tools, reduce the expenses and solve tasks in a short period of time.
