正式放弃在我的小黑上安装10g RAC的打算。

本来给小黑配置了250g的硬盘,应该是够快了,可惜,小黑的心才1.66,而且内存似乎也不够,经过无数次努力,只要把两个虚拟机打开,cpu温度就直接上85摄氏度左右,而且硬盘转速也抗不住。因此,无数次虚拟机死机后,正式放弃在小黑上搭建linux+oracle 10g rac的计划。

准备用公司在广州分公司的公网地址来作这个环境,目前已知的该环境是2颗双核的cpu,内存8g,硬盘我占了60g,似乎是scsi盘,硬盘速度足够,将转战到那里去整,反正远程过去也蛮方便的,远程桌面而已。公司能提供如此环境,真的是很开心。

这次总应该能顺利搭建起我的rac环境吧。不过无数次的折腾后,发现该碰到的问题都碰到过,实在是太有意思了。

碰到问题,解决之,何尝不是一种快感!


最近的怪事蛮多。

首先是那天我晚班,下午去公司,同事说下午2点左右地震了,我靠,那可是6月12日,难道是汶川地震1个月的纪念,再问下去,原来是那个时候一台伟大的DS8300可能是站着太累了,居然在机房去睡了会,1.4吨的家伙,这么一睡,那动作和地震差不多。晚饭后去机房看望了下这哥们,嗯,这是第一次我有意识的去看8300,结果还是刚睡醒的,这种看8300倒地的机会还真不多,可惜我去看望的时候8300已经站起来了,不过没人敢给它上电了。有多少人见过8300倒地呀?

今天晚上在家值班的时候,收到电话,晚上要重新起停一个rac库。不是很重要的系统,所以服务器也不是很好,IBM P560Q而已,也没怎么在意,这种活已经习惯了,都不会紧张了,先把库拉掉,很正常,然后IBM的哥们在机房给加内存,装好了,HA起来,正常,然后我拉库。拉呀,第一个节点起来正常,拉第二个节点呗,启动到nomount就不动了,检查alert.log

也没啥好看的,把先拉起来的节点down掉,2号节点就立刻起来了。这问题好像以前见过,我记得好像是如果参数cluster_interconnects不对的话,会有这种问题,嗯,那就整呗,这个参数也正常,每个instance单独起来都会对。难道是,莫非是见鬼了,ok,再想想,似乎两个主机交换的hacmp的网络会引起这种问题,先检查tty0,正常,再检查网卡的参数MTU,也正常。

无论如何,我一定坚信,这个是HA的问题或者是网络的问题,明显资源有问题。再看看metalink,发现也是这些东西,但是metalink说的这些都没有问题的,继续折磨IBM的哥们,让他们去查网络,终于,10分钟后,有好消息了,RAC的网络光纤出现了问题,我靠,不就是下个电吗,有这么麻烦的加内存动的是前面,又不是后面,光纤,你咋坏了列。赶紧的兄弟们换光纤线,重新拉库。正常了。

不是8300倒地,就是光纤不行,是我该去烧香,还是IBM的哥们该去了列?


我会吹泡泡,你会吗?


我100天了,干吗喊我起来,我还没睡醒列


我100天了,妈妈在干吗,给我拍照吗?我还没准备好,等我摆个好点的POSE不行呀.


我是个男孩子,如假包换


饿了,我爸爸把我的奶粉钱都花完了,只能自己吃手指了,看看能不能饱.


嘘,我睡着了,别吵,梦里好多漂亮MM呀.


准备在7,8,9这三个不忙的月份,好好的奋发学习下ORACLE,作作试验。就买了个250G的硬盘,把原来的80G的硬盘从小黑上换下来了。

现在的感觉,很象暴发户, 以前呀,看到很多好东西想放机器上,总是空间不足,每次都要去忍痛删除一些东西,现在终于不用了,我想放哪里放哪里,想放啥放啥,呵呵。真开心的来。

好好搞点资料看看,视频教程呀,不过不知道能不能下到OCM的视频教程。然后搞点啥列,哦,对了,搞个VMWARE的RAC环境,以前一套都搞不了,现在,俺搞两套,一套作主库,另外一套作DG的容灾环境。这样不就是想搞啥都可以了吗?

下一步该把2G的内存换到最少4G了,要不DG环境搭不起来。嗯,攒钱,买内存!

PS:最坏的是小占同学了,听说我用上了250G的硬盘,直接告诉我说 D:/JAPAN/AV 200G,唉,这孩子,从哪里学的呀。算算也不化算吗,去电子市场,RMB 5元的,500块可以买100张,500G了,我这才200G,多亏呀是吧。坚决不上那孩子的当。开始学习了,要相信知识改变命运,学习成就未来!


从今天开始,

准备10G OCM考试,看看多久能整出来!

以后也没有酒喝了,唱歌啥的娱乐也全部取消了,有时间就看书做试验吧,好好的学习下,很久没有用功的看看书了,不知道是不是老了,看书都觉得吃力.坚持下,一定能成功的!
