MSMQ 歷險記

 

MSMQ Overview

保哥的心得分享，深入淺出的介紹 MSMQ，並且許多有用的連結，推薦先看這一篇

錯誤訊息：Access to Message Queuing system is denied

MSMQ 3.0 too secure for you?

http://blogs.msdn.com/b/johnbreakwell/archive/2007/01/15/msmq-3-0-too-secure-for-you.aspx

小熊子測試的結果，上面的選項沒有用，跨 Domain 時，直接設定 Queue 安全性屬性 ANONYMOUS_LOGON=> Full Control

這邊有一個 step by step

錯誤訊息：The Message Queuing service is not available

*檢查防火牆是否有擋下 mqsvc.exe ?

*是否有開啟 MSMQ Service ?

*檢查 MSMQ 路徑格式是否有錯?

PUBLIC=QueueGUID
DIRECT=Protocol:ComputerAddress\QueueName
DIRECT=OS:ComputerName\private$\QueueName
PRIVATE=ComputerGUID\QueueNumber

OR

DIRECT=AddressSpecification\QueueName  (For public queues)
DIRECT=AddressSpecification\PRIVATE$\QueueName  (For private queues)
DIRECT=AddressSpecification\QueueName;JOURNAL  (For public queue journals)
DIRECT=AddressSpecification\PRIVATE$\QueueName;JOURNAL  (For private queue journals)
DIRECT=AddressSpecification\SYSTEM$;computersystemqueue  (Introduced in MSMQ 2.0 for the computer journal and dead-letter queues.)
DIRECT=URLAddressSpecification/QueueName  (Introduced in MSMQ 3.0)
(小熊子常常 OS:<ComputerName> 會寫成 OS:<IP> 當然會出錯!!)

 

 

如何遠端傳送 private Queue ?

這兩篇文章很不錯

MSMQ - Receiving messages from remote private queues

如何取得 Outgoing Queues

為什麼會需要檢查Outgoing Queue? MSMQ 在 Send Remote Queue 時，會先丟到本機的 Outgoing Queues，而且程式上不會出錯，但訊息有可能會卡在這個部份，所以需要程式化來做監控。

• 引用 COM (Microsoft Message Queue 3.0 object library ; c:\windows\system32\mqoa.dll)
• 使用 MSMQApplication.ActiveQueues 取得目前活動的 Queue
• 利用 MSMQManagement.Init 取得 MSMQOutgoingQueueManagement 物件，透由 MSMQOutgoingQueueManagement.State 來判斷是否存活
• 參考

如何取得 Queue 裡的訊息數

• 這個方法好，而且是純 .net
  Counting Messages in an MSMQ MessageQueue from C#
  http://jopinblog.wordpress.com/2008/03/12/counting-messages-in-an-msmq-messagequeue-from-c/
  
• 這篇提到兩種作法
  1.用 Performance Counter - MSMQ Queue 取得
  2.用 COM (Microsoft Message Queue 3.0 object library ; c:\windows\system32\mqoa.dll) 取得
  也可以參考
  Counting messages in Queue - the .NET version
  http://msmq.spaces.live.com/blog/cns!393534E869CE55B7!121.entry
  
• 這篇也是用 COM
  Accessing Outgoing Message Queues (MSMQ)
  http://www.codeproject.com/KB/IP/MSMQ.aspx
  
• 這篇用 P/Invoke 取得 MQMgmtGetInfo
