在 RHEL 7.x 或 OVA 上的 OnCommand Unified Manager 9.5 上，采集服务器不会保持启动状态

适用场景

• OnCommand Unified Manager 9.5 
• RHEL 7.x
• 虚拟设备

问题描述

从 Unified Manager 9.4 升级到 9.5 后， "ocieau " 服务不会保持联机。

由于 OnCommand 采集服务已关闭， OCUM/Unified Manager 9.x 无法监控所有集群。
升级
OnCommand Unified Manager 后， OCIEAU 服务不会在 RHEL 7.x 上保持联机采集停止。

检查 ocieau 服务的状态：
