Another way for forcing SQL Server to log the error messages related to deadlock is using the server-side trace, meaning that we have to turn on Trace Flags 1204 and 1222. This will ensure that above mentioned errors are logged, but in this way a quite verbose logging information will be...
◦Deadlock frequency can sometimes be reduced by ensuring that all applications access their common data in the same order – meaning, for example, that they access (and therefore lock) rows in Table A, followed by Table B, followed by Table C, and so on. taken from: http://publib....
In specific SQL Servers databases, I have deadlock problems that often result in significant performance degradation. When the deadlocks occur frequently in my environment, the deadlocks often become a performance killer for the overall application. If the deadlocks become severe enough, I need to dr...
In contrast, the overload of TryEnter that doesn't accept a time value defaults to using a timeout of 0, meaning that it will return false if the lock cannot be acquired immediately (again, our implementation will also throw an exception if acquiring the lock would cause a deadlock; this...

I have 2 threads running transactions that can update the same row in a table at the same time. I have no problem protecting the row itself from concurrent access, but Sql Server is deadlocking while trying to update the primary key. According to the deadlock graph, both transactions have...
I am seeing a C3P0 log dead lock issue in an Apache Tomcat application. Not long after this I begin to see failures in Tomcat due to resource limits. This then causes the number of httpd daughter processes to increase until the maxRequestWorkers limit is hit and the server then deadlocks....
