OSW Analyzer分析oswbb日志发生异常

具体OSW Analyzer详细介绍可以参考MOS文档：

• OSWatcher Analyzer User Guide (Doc ID 461053.1)

我们常用的就是拿到一份osw数据到自己电脑，使用下面的方法进行分析：

Usage java -jar oswbba.jar -i <input archive directory containing the oswatcher log files>

我电脑系统是macOS，目前想参照这样的方法使用OSW Analyzer对一份从客户AIX环境生成的osw数据进行分析，执行如下命令：

java -jar oswbba.jar -i /Users/jingyuzhao/Documents/oswbb/archive/

结果屏幕大量输出异常，类似这样：

最开始走了弯路，以为是osw版本不一致导致，但换用相同版本的osw依然如此。
之后重新从这些大量的异常输出中看到还有时间格式的问题，开始尝试依据这个关键点先尝试解决时间格式问题，MOS有一篇在Win平台的格式问题：

• OSWatcher Analyzer Failed with "Cannot format given Object as a Date" and "Invalid data found" on Windows Platform (Doc ID 2247572.1)

核心内容就是说系统的日期格式设置是非英文的：date format is set to non-English。
参考解决方案：

You can modify the java command to below to resolve this issue:
java -Duser.language=en -Duser.country=us -jar oswbba.jar -i

虽然我不是Win平台，但看起来应该是类似问题，所以重新尝试用这种方式重新解析osw日志：

java -Duser.language=en -Duser.country=us -jar oswbba.jar -i /Users/jingyuzhao/Documents/oswbb/archive/

这次执行发现不再报任何错误，最终能够成功解析出OSW的采集数据。
