. Ex2 - Implementing MQ Trigger
. 讓我們來練習一下如何 Implementing MQ 的Trigger
.

====== Exercise 2. Implementing Trigger ======
1. Create an Initiation Queue named QL.INITQ_AP :
　# runmqsc QMC00A (QMC00A is your Queue Manager)
　DEFINE QLOCAL(QL.INITQ_AP) REPLACE

2. Create a Local Queue (named QL.QT1) which is enabled for Triggering :
　DEFINE QL(QL.QT1) REPLACE +
　　TRIGGER +
　　TRIGTYPE(FIRST) +
　　PROCESS(PR.ECHO) +
　　INITQ(QL.INITQ_AP)

3. Create a PROCESS (named PR.ECHO) to identify the application to be started. In such a way that amqsech is started synchronously with respect to the execution of the Trigger Monitor.
　DEFINE PROCESS(PR.ECHO) REPLACE +
　　APPLICID('/mqmtop/samp/bin/amqsech')　// UNIX Systems

　DEFINE PROCESS(PR.ECHO) REPLACE +
　　APPLICID('amqsech')　　　　　　　　　// Windows Systems

4. Use a Dynamic TEMP Queue (named QM.QT1_REPLY) as Reply-to-Queue which is created by a Model Queue :
　DEFINE QMODEL(QM.QT1_REPLY) REPLACE

5. Start the Trigger Monitor using the control command runmqtrm . Name the Initiation Queue.
　# runmqtrm -m QMC00A -q QL.INITQ_AP

====== Exercise 2.a Test Triggering with amqsinq ======
6. Test Triggering :
　# amqsreq QL.QT1 QMC00A QM.QT1_REPLY
　(打一些字然後按 Enter，會在 Trigger Monitor 視窗)

7. 把 QL(QL.QT1) 設成 TRIGTYPE(EVERY) 再試試看：
　DEFINE QL(QL.QT1) REPLACE +
　　TRIGGER +
　　TRIGTYPE(EVERY) +
　　PROCESS(PR.ECHO) +
　　INITQ(QL.INITQ_AP)

8. 把 QL(QL.QT1) 設成 TRIGTYPE(DEPTH) 再試試看：
　DEFINE QL(QL.QT1) REPLACE +
　　TRIGGER +
　　TRIGTYPE(DEPTH) TRIGDPTH(6) +
　　PROCESS(PR.ECHO) +
　　INITQ(QL.INITQ_AP)

====== Exercise 2.b Test Triggering with amqsinq ======
9. Create a 2nd PROCESS object for amqsinq :
　DEFINE PROCESS(PR.INQ) REPLACE +
　　APPLICID('/mqmtop/samp/bin/amqsinq')　// UNIX Systems

　DEFINE PROCESS(PR.INQ) REPLACE +
　　APPLICID('amqsinq')　　　　　　　　　// Windows Systems

10. ALTER the QL(QL.QT1) appropriately :
　ALTER QL(QL.QT1) PROCESS(PR.INQ)

11. Run amqsreq again, remembering that amqsinq now expects the application data in each message to contain the name of a Queue. For example, use the names of the following Queues :
　# amqsreq QL.QT1 QMC00A QM.QT1_REPLY
　
　SYSTEM.ADMIN.COMMAND.QUEUE
　QM.QT1_REPLY
　SYSTEM.SAMPLE.REPLY
　QL.QT1
　=> Try an invalid Queue name.


===============================
====== 補充：Channel Trigger ======
===============================
※ 不需要 Trigger Monitor，也不需要 Data ，亦可以避免 Channel Expire 的暫停。

[QM1] (Listen : 1414)
　XXX.QR →→→ YYY.QL
　
　QM2.XMITQ ---Trigger
　---> SYSTEM.CHANNEL.INITQ
　--->　QM1.To.QM2 (SDR)

[QM2] (Listen : 1415)
　YYY.QL
　
　QM1.To.QM2 (RCVR)

　　ALTER XMITQ
　　TRIGGER Control ON
　　TRIGGER TYPE FIRST
　　TRIGGER DATA(Channel Name)
　　INITIATION QUEUE
　　SYSTEM.CHANNEL.INITQ
