ERROR:

ORA-00257: Archiver error. Connect AS SYSDBA only until resolved.

2 問題查看

1）查看ORA錯誤

[oracle@odd agent]$ oerr ora 00257

00257, 00000, "Archiver error. Connect AS SYSDBA only until resolved."

// *Cause: The archiver process received an error while trying to archive

// a redo log. If the problem is not resolved soon, the database

// will stop executing transactions. The most likely cause of this

// message is that the destination device is out of space to store the

// redo log file. Another possible cause is that a destination marked

// as MANDATORY has failed.

// *Action: Check the alert log and trace files for detailed error

// information.

2）查看告警日志

3 解決方案

通過上面的問題查看，發現閃回恢復區的空間被歸檔日志占滿，導致無法對歸檔日志進行歸檔，查看數據字典視圖v$recovery_area_usage發現歸檔日志的占用空間很大，故解決辦法是刪除歸檔日志或者增大快閃恢復區的空間。

1）增大快閃恢復區

ALEN@PROD2> alter system set db_recovery_file_dest_size=10G;

2）刪除歸檔日志（刪除前需確認能否直接刪除）

RMAN> delete archivelog all;
