这个视频好友多多曾在微信上给我们几个发过，但当时我没仔细看，只看了个开头，今早在微信圈圈上又看见了，然后点开仔细看了下，看完就彻底无法忘却。
现在我这个年纪，基本上已经没有大学时年轻冲动易被很多人事影响的躁动心理，对于现在目睹的很多东西，无论是人还是事还是物，基本上已经不会轻易产生多大感触，或许可以说是更成熟了，对很多人事有自己的判断认知和想法，但更多的可能是对工作生活的现状已经麻木了！
对于该视频中演讲者提到的观点深入我心：时间就是生命，我们每天就是用生命在生活，珍惜自己生命的最好的途径是什么，就是把自己的生命淋漓尽致地燃烧，而这一切的前提都是获得快乐！
TFA Collector工具是一个诊断收集工具，用来简化Clusterware/Grid Infrastructure/RAC/Single Instance数据库系统诊断数据收集，关于MOS对TFA说明：
Trace File Analyzer Collector (TFA) is a diagnostic collection utility to simplify diagnostic data collection on Oracle Clusterware/Grid Infrastructure, RAC and Single Instance Database systems. TFA is similar to the diagcollection utility packaged with Oracle Clusterware in the fact that it collects and packages diagnostic data however TFA is MUCH more powerful than diagcollection with its ability to centralize and automate the collection of diagnostic information. TFA provides the following key benefits:
1)Increase Productivity with Reduction in time and effort in diagnostic collection
Diagnostic collection is performed with a single command executed from a single node
Diagnostics collected include log and trace files for Grid Infrastructure/Oracle Clusterware, ASM, RAC and the OS
Output is consolidated to a single node for ease of upload
2)Reduce diagnostic data uploads to support by a factor of 10x or morein most cases
Diagnostic files are isolated and trimmed to only include data for incident time
3)Reduce SR Resolution times
Proper diagnostics collection for incidents ensure complete diagnostic data collections thus minimizing the need for support to request additional data
4)Ensure that proper Diagnostic Tools are in place to better deal with Reactive types of issues
