はじめに

宛先サーバへの配送が一時的にできないような状況では、ESAはメッセージの配送を再試行します。本稿ではこの再試行動作についてご紹介いたします。

 

Bounce Profileの設定

 再試行の動作はBounce Profileに設定されており、defaultでは以下のようになっています。

ESA GUI > Network> Bounce Profiles > Default
default_bounce_profile.png

最大再試行回数: 100回
キューでの最大保持時間: 259200秒(3日)
メッセージあたりの初期待ち時間: 60秒
メッセージあたりの最大待ち時間: 3600秒(60分)
----------

宛先サーバからの応答がなく、接続がタイムアウトする場合には以下の設定が適用されます。

ESA GUI > Network> Bounce Profiles > Global Settings
bounce_profile_global_Settings.png
到達不能ホストを初回再試行するまでの待ち時間: 60 秒
到達不能ホストの最大許容再試行間隔: 3600 秒(60分)
----------

 

サーバ側からレスポンスがある場合

再送間隔は以下のように徐々に大きくなっていき、最大間隔は60分となります。

接続 間隔 経過時間
1回目   0分
2回目 1分 1分
3回目 2分 3分
4回目 6分 9分
5回目 18分 27分
6回目 54分 71分
7回目以降 60分ごと 131分
注: レスポンスを受信するまでの時間を考慮しない場合の理論値です。

この場合、理論的には77回の試行(最初の試行+76回の再試行)が行われることになります。

サーバ側からレスポンスがない場合

 サーバ側からの戻りパケットがなく通信がタイムアウトする場合には、以下のように接続を試みます。

接続 ログ出力間隔 経過時間
1回目   1分
2回目 2分 3分
3回目 5分 8分
4回目 15分 23分
5回目 45分 68分
6回目以降 61分 129分

それぞれの接続は1分後にタイムアウトと判断されるため、Connection Errorのログは最大で61分ごと(最大間隔60分+1分のタイムアウト)に出力されることになります。この場合の試行回数の理論値は75回(最初の試行+74回の再試行)となります。
