PRB: Log Reader Agent Does Not Function and You Receive an Error Message During Transaction Replication

When you use transaction replication to distribute the data, you may experience the following symptoms:Log Reader Agent does not replicate the data and it displays the following error message:


The process could not execute 'sp_replcmds' on servername.


The log file contains the following information:
Status: 2, code: 0, text: 'The process could not execute 'sp_replcmds' on servername'. The process could not execute 'sp_replcmds' on servername. Status: 2, code: 0, text: 'Timeout expired'. Disconnecting from Publisher servernameThe agent failed with a 'Retry' status. Try to run the agent at a later time.

CAUSE:
To facilitate transactional replication, Log Reader Agent moves the transactions that are marked for replication from the transaction log on the publisher to the distribution database. You may receive this error message when Log Reader Agent cannot move the transaction log within the time limit that you set in the Log Reader Agent QueryTimeout property.

Asynchronous Socket Programming in C#

Objective The objective of this article is to demonstrate a socket-based client/server application that will allow two-way asynchronous communication between a server and multiple client applications. Because this example uses asynchronous methods, the server application does not use threads to communicate to multiple clients (although internally the asynchronous communication mechanism uses threads at the OS level). The Difference Between Synchronous and Asynchronous Communication in Network Programming The key difference between synchronous and asynchronous communication can be explained with an example. Consider a server application that is listening on a specific port to get data from clients. In synchronous receiving, while the server is waiting to receive data from a client, if the stream is empty the main thread will block until the request for data is satisfied. Hence, the server cannot do anything else until it receives data from the client. If another clien
