ORA-00263: there are no logs that need archiving for thread string

文档解释

ORA-00263: there are no logs that need archiving for thread string

Cause: An attempt was made to manually archive the unarchived logs in this thread but no logs needed archiving.

Action: No action required.

ORA-00263是一个Oracle数据库错误,它指出线程(指定的特定事务)的日志记录不需要归档。

官方解释

ORA-00263: 无需归档线程 string 的日志

Cause: ALTER DATABASE ARCHIVELOG was issued, telling Oracle to archive the log for a specific log thread (sequence#) without any logs being ready to archive in that thread.

Action: Correct unnecessary ALTER DATABASE ARCHIVELOG command or wait until the log thread contains logs ready to be archived.

常见案例

此错误通常会在运行ALTER DATABASE ARCHIVELOG命令后发生,该命令会激活指定线程中的归档日志操作。但是,如果在某些情况下,指定线程中没有任何准备好进行归档的日志,则会发生错误,导致此错误发生。

正常处理方法和步骤

1.首先,检查指定的线程中是否有可供归档的日志。可以使用以下SQL语句来完成:

SELECT THREAD# FROM V$LOG WHERE ARC-STATUS = ‘NEEDED’;

如果没有可归档的日志,可以考虑等待归档日志的准备,或者重新发布ALTER DATABASE ARCHIVELOG命令,而这次指定不同的线程。

2.如果指定线程中存在需要归档的日志,则可以考虑对该命令进行修复。如果线程中存在错误,可以使用以下命令来修复错误:

ALTER DATABASE RECOVER LOGFILE (’THREAD#’);
