Sometimes we close our antenna only because we are concerning too much about our own safety.  We may lose too many opportunities…

Due to the fare of losing safety, we may even forget the original goal of ourselves. We refuse to receive new idea that is never heard of. We stop doing things we are doubting of. We close our mouths with the opinions we are uncertain of…

Yes, undeniably, to some extent, it’s safest to be silent. There will be nothing wrong if we’ve done nothing. The more we say, the more mistake we will make. The same is to what we have done. But higher risk also leads to higher gain. If we never stop taking the high risk, even if we lose once and once and once again, we will be strong in the end as a giant some day in the future.

We may receive much more information when we turn on our antenna and start to receive information from the whole colorful world. The only point is that we have to do some triage and pick those useful to ourselves.

Word stops, as mind stops…

saphires Database, 流水帐

自从来到这里，就开始有同事朋友向我咨询Oracle DB的技术问题。。。偶在这里严正的声明一下，不是在Oracle上班的都会用Oracle DB！！！

不过也没有办法，虽然挺讨厌这玩意儿，经常打Linux和DB的擦边球，对DB一无所知毕竟也不是一件好事。硬着头皮，得把这件事提上日程。

先从连接开始：

$ export ORACLE_HOME=xxxx
$ export ORACLE_SID=xxx
$ export PATH=$PATH:$ORACLE_HOME/bin
$ sqlplus sqlplus user/pass@host

再查一下表空间：
select TABLE_NAME from ALL_TABLES;

标准SQL都还好，就是这些product specific的东西入不了门。ft!
