database-deadlocks

I want to make a script where the oracle sessions which go into a deadlock are killed automatically.Is it possible to find out the session id for the sessions which go into a deadlock.As of now I have to bounce the database to remove the deadlock.Is any solution to this problem possible? I want to make a script where the oracle sessions which go into a deadlock are killed automatically EDIT Explained in a better way, corrected few sentences, and added a test case to demonstrate deadlock scenario. Why do you want to re-invent the wheel? Oracle detects a deadlock automatically, throws ORA-00060:

I am receiving a lot of deadlocks in my big web application. How to automatically re-run deadlocked transaction? (ASP.NET MVC/SQL Server) Here I wanted to re-run deadlocked transactions, but I was told to get rid of the deadlocks - it's much better, than trying to catch the deadlocks. So I spent the whole day with SQL Profiler, setting the tracing keys etc. And this is what I got. There's a Users table. I have a very high usable page with the following query (it's not the only query, but it's the one that causes troubles) UPDATE Users SET views = views + 1 WHERE ID IN (SELECT AuthorID FROM

What is deadlock in sql server and when it arises? What are the issues with deadlock and how to resolve it? Pz. In general, deadlock means that two or more entities are blocking some sources, and none of them is able to finish, because their are blocking sources in a cyclic way. One example: Let's say I have table A and table B, I need to do some update in A and then B and I decide to lock both them at the moment of usage (this is really stupid behaviour, but it serves it's purpose now). At the same moment, someone else does the same thing in opposite order - locks B firstly, then locks A.

We have a single table which does not have references to any other tables. ┬────────────┬─────────────┬───────────────┬───────────────╮ │id_A(bigint)│id_B(bigint) │val_1(varchar) │val_2(varchar) │ ╪════════════╪═════════════╪═══════════════╪═══════════════╡ The primary key of the table is a composite of id_A and id_B. Reads and writes of this table are highly concurrent and the table has millions of rows. We have several stored procedures which do mass updates and deletes. Those stored procedures are being called concurrently mainly by triggers and application code. The operations usually look

I've implemented a generic repository and was wondering if there is a smart way to implement a retry logic in case of a deadlock exception? The approach should be the same for all repository methods. So is there anyway I can avoid writing 'try/catch - call method again with retry-count', in every single method? Any suggetsion are welcome. A bit of my Repository code: public class GenericRepository : IRepository { private ObjectContext _context; public List<TEntity> ExecuteStoreQuery<TEntity>(string commandText, params object[] parameters) where TEntity : class { List<TEntity> myList = new List
