(可选)。对于运行 Oracle Parallel Server (OPS) 的群集节点,请关闭所有 OPS 数据库 实例。
有关关闭过程,请参阅 Oracle Parallel Server 产品文档。
成为要关闭的群集节点上的超级用户。
使用 scswitch 和 shutdown 两个命令关闭群集节点。
在要关闭的节点上,输入以下命令。
# scswitch -S -h node # shutdown -g 0 -y -i 6 |
shutdown 的 -i 6 选项使节点 在 ok PROM 提示符下关闭后又重新引导。
群集节点必须有到群集互联的工作连接,才能获得群 集成员的身份。
检验节点是否已引导且没有错误,并且处于联机状态。
scstat(1M) 命令报告一个节点的状态。
# scstat -n |
以下示例展示关闭并重新启动节点 phys-schost-1 时的控制台 输出。-g 0 选项将宽延期设置为 零,-y 自动提供对确认问题的 yes 响应。群集中其他节点的 控制台上也显示此节点的关闭和启动消息。
