  • 为老虎队喝彩~~

    Posted on February 14th, 2010 Sean Add comments

         大年三十的春晚,就像曹操嘴里的鸡肋,嚼在嘴里没什么味道,吐了又觉得牙齿就变得不是牙齿,是寂寞…
         至少今年的春晚,久违的小虎队又出现了。虽然严格意义上说,这三个在我小学时已经是高中生的帅哥倒可以被称为“老虎队”。但当他们登台唱歌,尤其是又唱起“蝴蝶飞呀”时,感觉自己仿佛刹那间失去了知觉:小学时蹲在音像店旁蹭听,课外活动时老师一句一句地教大家唱“贝壳爬上沙滩,看一看世界有多么大”……一切的一切,都一丝一丝地刺入大脑。
         不知为什么?!难道我也变得多愁善感了…

  • Create tablespace on NFS based LINUX + Oracle

    Posted on February 8th, 2010 Sean Add comments

         When the first time to create tablespace on SQLplus, it shows:

    “ORA-27040: file create error, unable to create file. Linux-x86_64 Error: 13: Permission denied”

    So I just change my home directory to “777”, then getting the error

    “ORA-27054: NFS file system where the file is created or resides is not mounted with correct options”

         After check the “autofs” settings, I found the content of file “auto.home” has problem which is something wrong with NFS mount options. The solutions is change the original content

    * -fstype=nfs,soft,intr,rsize=8192,wsize=8192,nosuid,tcp oracle.server.com:/users/&

    to

    * -rw,bg,hard,intr,rsize=32768,wsize=32768,suid,nfsver=3,tcp oracle.server.com:/users/&

  • Google的手机:Nexus One

    Posted on February 1st, 2010 Sean Add comments

         尽管Steve Jobs在IPad发布会上忍不住大骂Google背信弃义,Google的Nexus One依然是众多人追捧的对象。与之iPhone相比,multitask是其最大亮点。Google为了让这一亮点突出,特意在Nexus One上使用1Ghz的CPU和512MB的内存。在看了测评后,发现Google的这一用心良苦果然在Nexus One的运行速度上得到了回报:
