The upside to this transfer is better performance. In general, therefore, snapshot isolation puts some of the problem of maintaining non-trivial constraints onto the user, who may not appreciate either the potential pitfalls or the possible solutions. The next section is "Making Snapshot Isolation Serializable" to get around this. Read "Snapshot isolation" (Wikipedia) for more on write-skew anomalies. What are the pros and cons of setting READCOMMITTEDSNAPSHOT ON in SQL server 2008 Actually i was running through the the problem of transaction deadlockS, but by setting READCOMMITTEDSNAPSHOT ON on and disabling the Lock Escalation (only on table that used in transactions that causing deadlock). Most important, snapshot isolations are not safe in many cases by default. It assumes the current DB is the one you want to set for snapshot mania and will execute only on SQL 2005 without throwing errors on SQL 2000. However, the behavior was the same on a SQL Server 2017. This test was performed on a SQL Server 2019.
READCOMMITTEDSNAPSHOT is not enabled, because actually read committed should isolate sufficiently. "Performance Impact: The Potential Cost of Read_Committed_Snapshot" (Linchi Shea) Unfortunately, some queries returned values like 48005, which I can't explain, because all connections were in read committed mode.Outstanding transactions block all the queries related to background processing. This is fine, and this is the correct behavior to ensure all is working correctly. If a database has been enabled for snapshot isolation but is not configured for READCOMMITTEDSNAPSHOT ON, you must initiate a SqlTransaction using the IsolationLevel.Snapshot enumeration value when calling the BeginTransaction method. Hangfire uses READ COMMITTED isolation level to serialize access to background jobs, preventing it from fetching stale data. It will also increase load on your tempdb and CPU. Snapshot isolation is supported in ADO.NET by the SqlTransaction class. If you have locking problems then you have a problem with your code: it isn't the database engine.
