I have gone through a scenario when some of backup images were no longer required and we decided to discard those images and reuse the media. This is how we achive it. 1. Verify if there are valid images on the tape. 2. Expire images. 3. Verify if the tape

Introduction Collecting and visualizing data is an important way to make informed decisions about your servers and projects. In a previous guide, we discussed how to install and configure Graphite to visualize data on our servers. However, we didn't have a good way of collecting or even passing

netdata supports backends for archiving the metrics, or providing long term dashboards, using grafana or other tools, like this: Since netdata collects thousands of metrics per server per second, which would easily congest any backend server when several netdata servers are sending data to it, netdata allows sending metrics at

幫同事把壞軌的系統硬碟復制到新的硬碟上，其本上有二種方法我都有試過 1. 不使用原機內壞軌硬碟擔心有必要檔案毀損，所以另外找一台同樣是T420的Windows 7 x64主機，安裝啟用Lenovo recovery and rescure tool將作業系統基礎備份到USB外接碟或經由eSATA接到第二顆硬碟，記得用進階模式才有比較可以用的選項好設定，這個方法很方便也都可以成功從備份好的硬碟直接開機寫回新的硬碟。 2. 使用原機內壞軌硬碟作為復原來源，使用DOS模式的ghost 11搭配參數 /IB，過程中匆略有壞軌區域並持續完成復制，完成後用Windows 7 x64 安裝光碟修理開機程序。這裡有幾個地方要注意，比如我是用卡碟機燒Windows7 x64 安裝光蹀來作修復，他會把開機磁碟用在卡碟機記憶卡的空間，另外還遇到BIOS設定開機模式有利用Both mode表示開機方式同時支援EFI和MBR，這會使Windows 7開機修理程式出錯 " The system partation was not fount". 必需將BIOS內開機模式指定成Legacy也就是MBR開機，

表空間的狀態 – ONLINE和OFFLINE 2014/08/16 來源：CSDN博客 前幾天問一個表空間狀態的問題，也暴露了自己基礎知識的薄弱，之所以總結如下兩篇博文，主要還是讓自己靜下心來，補一下相關知識點，並通過實踐強化自己的理解。 主要參考： 《11g Concept》 《11g Administrator's Guide》 表空間的ONLINE和OFFLINE狀態 1. 只要資料庫處於OPEN狀態，除了SYSTEM表空間外的其他表空間，都可以將其置為online或offline狀態。SYSTEM表空間之所以不能置為offline，是因為其中保存的數據字典需要一直使用。將表空間置為offline，可能的原因包括維護、備份以及恢復等目的。 3. 如果表空間處於offline狀態，那麼Oracle不會允許任何對該表空間中對象的SQL執行。表空間置為offline時仍處於活動狀態的語句在交易級別並不會受影響。Oracle會保存這些尚未完成語句相關的回滾數據到SYSTEM表空間。當表空間置為online時，如果有必要，那麼Oracle會應用這些回滾數據
