ORA-26896: Attempted to connect multiple Oracle GoldenGate Capture processes, including “string”, with XStream outbound server “string” through queue “string”.”string” ORACLE 报错 故障修复 远程处理

文档解释

ORA-26896: Attempted to connect multiple Oracle GoldenGate Capture processes, including “string”, with XStream outbound server “string” through queue “string”.”string”

Cause: An attempt was made to connect multiple Oracle GoldenGate Capture processes through a queue with the XStream outbound server.

Action: Each XStream outbound server can only connect with one co-located Capture process. Remove extra Capture processes.

ORA-26896 错误意味着用户已尝试将多个 Oracle GoldenGate Capture 进程连接到 XStream 出站服务器通过队列。

官方解释

在使用 Oracle GoldenGate 来将目标数据传输到 Oracle Database 中的可复制中继队列(XStream)时,Oracle GoldenGate 支持多个 GoldenGate Capture 进程连接到同一 XStream 出站服务器共享队列实例。XStream 将从 Capture 进程收集的数据再配置到 Replicat 进程的每个数据库实例中,以此实现灵活的数据传输。

但是,GoldenGate 只允许一个 Capture 进程绑定到同一个队列。多个 Capture 进程尝试将同一队列绑定到 XStream 出站服务器时会抛出 ORA-26896 错误,示警用户代码重复错误。

常见案例

当用户将多个 Oracle GoldenGate Capture 进程用于捕获不同源数据库中相同队列时,会导致 ORA-26896 错误。

一般处理方法及步骤

1. 使用专属的 XStream 出站队列来启动 Capture 进程,但一次只能启动一个。

2. 重新检查 Capture 过程的配置,确保不要反复尝试绑定同一个 XStream 队列。

3. 检查重复的 GoldenGate Capture 进程名称,替换为不同的名称。
