IBM MQ メッセージング・プロバイダー・アクティベーション・スペックとMQとの接続が切れた場合の再接続の動作

### 以下の環境で実行しています
https://qiita.com/keniooi/items/506c913a9d339a10e24e


### 1.MQを停止
```
[root@c90105v1 ~]# date; podman stop mq
Tue Apr 30 09:23:30 PM PDT 2024
WARN[0010] StopSignal SIGTERM failed to stop container mq in 10 seconds, resorting to SIGKILL
mq
```

### 2.WASで警告 CWSJY0003W が発生
最大５回、300000ミリ秒おきに再接続が試行される。
秒数と回数は[IBM® MQ リソース・アダプターのプロパティーの構成 - IBM Documentation]( https://www.ibm.com/docs/ja/was/9.0.5?topic=provider-configuring-properties-mq-resource-adapter )の下記設定によるもの。

>Reconnection retry count
    接続が失敗した場合に、 IBM MQ メッセージング・プロバイダー・アクティベーション・スペックが IBM MQ キュー・マネージャーへの再接続を試行する最大回数。

>Reconnection retry interval
    IBM MQ メッセージング・プロバイダー・アクティベーション・スペックが IBM MQ キュー・マネージャーへの再接続を再試行する前に待機する時間 (ミリ秒)。

### 3.もう一度MQを起動してみる。
WASにはログは出ず、MQを起動するだけではなにも起きない。
```
[root@c90105v1 ~]# date; podman start mq
Tue Apr 30 09:56:06 PM PDT 2024
mq
```

### 4.もう一度MQを止めてみる。
MQに接続していないため、MQを停止してもなにも起きない。
```
[root@c90105v1 ~]# date; podman stop mq
Tue Apr 30 10:06:35 PM PDT 2024
WARN[0010] StopSignal SIGTERM failed to stop container mq in 10 seconds, resorting to SIGKILL
mq
```

### 5.エンドポイントをResume
管理コンソールで
```
Endpoint jms_war#jms.war#PdprofMdb_J2CMessageEndpoint (AS) is already active.
```
となる。なにも変わらない。

### 6.エンドポイントをPauseしてResumeしてみる

Pauseのログ
```
[5/1/24 5:17:05:218 UTC] 00000096 ActivationSpe I   J2CA0524I: The Message Endpoint for ActivationSpec AS (com.ibm.mq.connector.inbound.ActivationSpecImpl) and MDB Application jms_war#jms.war#PdprofMdb is deactivated.
```

Resumeのログ。メッセージ・エンドポイントとMDBアプリケーションがアクティベートされた。
```

```

## 結論
### 1.MQとの接続が切れると、IBM® MQ リソース・アダプターの設定に応じて、IBM MQ メッセージング・プロバイダー・アクティベーション・スペックは再接続を試行する。

[IBM® MQ リソース・アダプターのプロパティーの構成 - IBM Documentation]( https://www.ibm.com/docs/ja/was/9.0.5?topic=provider-configuring-properties-mq-resource-adapter )

>Reconnection retry count
接続が失敗した場合に、 IBM MQ メッセージング・プロバイダー・アクティベーション・スペックが IBM MQ キュー・マネージャーへの再接続を試行する最大回数。

>Reconnection retry interval
IBM MQ メッセージング・プロバイダー・アクティベーション・スペックが IBM MQ キュー・マネージャーへの再接続を再試行する前に待機する時間 (ミリ秒)。

### 2.再接続の試行で接続できないと下記のログが出る。
```
CWSJY0003W: MQJCA4014: Failed to reconnect one or more MDBs after a connection failure.
```

### 3. この状態で再接続するには、エンドポイントをPauseしてResumeする必要がある。
