分佈式緩存： Velocity之異常信息

Windows Server AppFabric 中的緩存錯誤消息包含一個錯誤代碼字符串和一個錯誤子狀態字符串。 本附錄提供錯誤消息和開發人員能夠用來處理這些錯誤的常量之間的鏈接。

如下錯誤消息是您可能在啓用緩存的應用程序的應用程序日誌中看到的內容示例：

ErrorCode <ERRCA0017>:SubStatus<ES0006>:There is a temporary failure. Please retry later. (One or more specified Cache servers are unavailable, which could be caused by busy network or servers. Ensure that security permission has been granted for this client account on the cluster and that the AppFabric Caching Service is allowed through the firewall on all cache hosts. Retry later.)

儘管該錯誤消息解釋了這個問題，但它並無告訴開發人員所生成的 DataCacheException 對象的確切類型。 在這種狀況下，DataCacheException 對象擁有一個 ErrorCode 屬性（其值爲 RetryLater）和一個 SubStatus 屬性（其值爲 CacheServerUnavailable）。 這容許開發人員使用異常處理來針對該錯誤採起更具體的操做，如重試調用。 還容許 IT 專業人士查找有關該錯誤的詳細信息。 對於本示例錯誤消息，在本文檔的下面部分有更詳細的幫助。 RetryLater (CacheServerUnavailable) （Windows Server AppFabric 緩存）。
