Monitoring Active Transactions for Improved Database Performance

Monitoring Transactions

Write a SQL query to monitor active transactions in the database.

Solution:

-- Query the system view to monitor transactions.
SELECT session_id, transaction_id, transaction_state, transaction_type
FROM sys.dm_tran_active_transactions;

Explanation:

• Purpose of the Query :
• The goal is to monitor active transactions for debugging or performance tuning.
• Key Components :
• sys.dm_tran_active_transactions: System view for transaction monitoring.
• Why Monitor Transactions? :
• Helps identify long-running or problematic transactions.
• Real-World Application :
• Useful for database administrators to troubleshoot performance issues.

Additional Notes:

• Monitoring active transactions helps identify bottlenecks, long-running queries, and potential deadlocks.
• Use dynamic management views (DMVs) like sys.dm_tran_active_transactions and sys.dm_tran_locks for detailed insights.
• Regularly review transaction logs and monitor database performance to proactively address issues.
