Problems solved by technology

[0004] 1. It may lead to deadlock or blocking. In the same logical transaction, the business code requires the resource to be locked before the write operation. If the lock fails, all locks under the same function sessionID need to be unlocked
[0005] 2. Transaction isolation level. In theory, the isolation level of logical transactions has no practical use. It is mainly used for database transactions. The current requirements are not very clear
[0006] 3. Transaction nesting, users need to care about the transaction isolation level, and need to understand the upper-level transactions

Embodiment

[0031] Embodiment: The following content is the data access of an instance of this method, and this instance applies transaction nesting.

[0032] Its specific implementation process is:

[0033] 1. Define the external transaction execution mode and transaction boundary type, and create logical transactions.

[0034] var ltrans = new GSPTransactionScope(GSPTransactionScopeOption, ScopeType.

[0035] 2. Perform data operations, create database instance objects, store the Sql statements to be executed, function SessionIDs, and database object names in thread-safe collections, see the following code:

[0036] using (var db = GSPDatabaseFactory. GetDataBase())

[0037] {

[0038] db. ExecSqlStatement(sql);

[0039] }

[0040] public override int ExecSqlStatement(string sqlStatement)

[0041] {

[0042] CheckForNullReference(sqlStatement, "sqlStatement");

[0043] int result = 0;

[0044] ...

Abstract

The invention discloses a method for integrating a native transaction and a logical transaction. The method includes the steps of creating a transaction, starting the transaction, subjecting the transaction to transaction management, submitting the transaction, and rolling back the transaction. Compared with the prior art, the method has the advantages that a logical transaction type and a logical transaction boundary type are applied, a user can start the transaction or directly submit the transaction, execution of submission and rollback of the logical transaction is determined according to the current transaction boundary type, inter-transaction deadlock is solved, and practicality is high.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method with strong practicability and fusion of native transactions and logical transactions. Background technique [0002] A database transaction is a sequence of operations performed as a single logical unit of work that is either fully performed or not performed at all. Transactions ensure that data-oriented resources are not permanently updated unless all operations within the transactional unit complete successfully. By grouping a set of related operations into an all-or-nothing unit, error recovery is simplified and applications are made more reliable. However, the database transaction must ensure that the transaction is in the same application, which is not applicable to the use between multiple frameworks, and it cannot guarantee that the operations between multiple frameworks are managed by the same transaction. [0003] In addition, using the combination of ...
