文档解释

ORA-26901: string propagation sender in the combined capture and apply mode is to be suspended while apply is disabled.

Cause: The corresponding subscriber was dropped or split.

Action: No action necessary.

ORA-26901一般用于在 combined capture and apply模式,string propagation sender 被暂停而apply被禁用时出现。这是因为当capture模式被禁用后,apply监视也会被禁用,无法执行string propagation sender功能。

OAUG官方给出的解释是:“如果Capture模式被禁用而Apply监视程序被启动,则会引发ORA-26901错误。重点是Capture模式必须被启动,以便Apply才能正常工作。此错误在启用Logical Standby时很常见。”

常见案例

一般处理方法及步骤

1. 检查logical standby状态,并确保capture模式是enable状态,如果不是,立即启动它;

2. 使用ALTER SYSTEM SET LOG_ARCHIVE_DEST_x APPLY=append命令;

3. 在logical standby源站,使用ALTER DATABASE START LOGICAL STANDBY APPLY;

4. 重新启动apply功能;

5. 最后,执行string propagation sender,更新apply数据库中的数据到logical standby中。
