Symptoms

在 DPA 資料存放區上,使用下列命令執行資料存放區匯入時:

Linux:  /emc/dpa/services/bin> ./dpa.sh ds 匯入配置和匯入檔案的名稱> --偵錯
Windows\emc\dpa\services\bin> dpa ds import location and name of import file> --debug
並非必填 --debug 參數,但會在畫面上顯示匯入進度的詳細資料。
觀察到以下錯誤:
[DEBUG] pg_restore: processing data for table "dpa.bkup_ddclone"
[DEBUG] pg_restore: processing data for table "dpa.backupevent"
[DEBUG] pg_restore: processing data for table "dpa.backup_media"
[DEBUG] pg_restore: processing data for table "dpa.backupjob"
[DEBUG] pg_restore: error: error returned by PQputCopyData: SSL SYSCALL error: EOF detected
[DEBUG] pg_restore: error: a worker process died unexpectedly
Completed in : 1min 52secs

Cause

此錯誤是由 DPA 資料存放區伺服器上的記憶體資源不足所造成。

Resolution

確認已設定最小記憶體需求,此需求已在 DPA 管理指南中概述。
也需要針對伺服器上的記憶體資源調整 DPA。

例如,如果 32GB 的記憶體分配給伺服器,DPA 應調整如下:
Linux:  /emc/dpa/services/bin> ./dpa.sh ds 調校 32 GB
窗戶:\emc\dpa\services\bin> dpa ds 32GB

需要重新開機 DPA 服務,才能進行調整以影響:
Linux:  /emc/dpa/services/bin> ./dpa.sh ds 重新開機
Windows\emc\dpa\services\bin> dpa ds restart

匯入現在應已順利完成。
