rac環境數據文件誤建到rac節點本地處理
在一次RAC例行巡檢時，查詢表空間的使用情況，節點1竟然拋出來，dbwr 進程無法lock ‘D:oraclefcdataLIXORA.DBF’ 這個數據文件；感覺不對啊，非常不祥的感覺；
光看名字就可以猜到，數據文件建到rac 節點2本地；
看下文件狀態吧：

果不其然，文件建到了rac 節點本地，而且數據文件名，要多奇葩，有多奇葩，這哥們真是縱觀古今，然後大手一揮，寫下‘hello word ’ 然後會心一笑。。。。。
我們的開發人員也是夠慘的啊，單機的oracle也搞不清楚，更不用涉及rac了。。。。。。。
再次確認下，dbfile 確實建在了/u01/app/oracle/product/10.2.0/db_1/dbs/ 目錄下
SQL> !ls /u01/app/oracle/product/10.2.0/db_1/dbs/

仔細看下內容好像哪裡有點問題吧？

總結：
開發人員嚴重缺乏對oracle 數據庫（單機，rac）的了解，當然這個也是管理上的疏忽；
從另一個方面也可以看出，業務用戶權限管理太粗狂，過於簡單粗暴，需要好好審計，規劃下；
具體其他的就不想再多說了。。。。。。。
