8月工作小记二三事

8月工作小记二三事

留下评论 , ,

    上个月，应该算是一个较为忙碌的工作月。其中：

    1 公事的一DBA同事离职，所有的数据库这块全部压到我1个人的身上，要看的库多了，任务重了，有些库也只能做到粗犷式管理了；

    2 出差2次，月初1次到上海，月末1次同样到上海；2次差旅虽说都是现场实施Oracle数据库环境的搭建，但都不是很顺利，究其原因：①项目前期同客户需求、准备工作都很有问题。如去之前，问项目组人员是实施RAC的数据库还是配置单实例的库，告知于我是单实例的库，结果一到客户现场方知是实施RAC的数据库；②个人的技术经验匮乏的短板也暴露的很明显了，尤其是存储方面的知识；

    3 快速记录这2次出差上海解决问题的方法：

        ① 月初去上海某客户遇到的问题，客户环境采用Dell R910单台服务器，存储采用Dell MD 3200。在阵列的管理界面将存储映射到主机时，发现找不到主机，原因：犯的是低级错误，Dell MD 3200 支持级联扩展存储，误将主机的SAS卡插到阵列上的SAS OUT扩展口上，而应该将其连接到阵列上的SAS IN口。其次，在做好阵列之后，重启主机、阵列之后，发现主机依然无法找到对应的LUN，解决方法：注释掉/etc/udev/rules.d/90-dm.rules配置文件。

        ②第2次去上海另1客户实施RAC时，同样碰到存储的问题。只是这次的主机是2台IBM X3650M3，存储是IBM System Storage DS3500磁盘阵列柜。在阵列上做好LUN并映射到主机后，还是不能正常发现存储设备，解决办法是安装IBM提供的RDAC补丁包。下述，记录安装RDAC软件包的过程，该软件包需要到IBM官方网站下载对应的操作系统版本和阵列型号的补丁。

Creating new MPP initrd image...
        You must now edit your boot loader configuration file, /boot/grub/menu.lst, to

        Now Reboot the system for MPP to take effect.
        The new boot menu entry should look something like this (note that it may
