Issue/Introduction

I encountered the following problem.

The PPM services were not running in English OS, Tomcat access log import/analyze job was completed but no record was imported. I detected "Unparseable date" warning. 

Why such warning messages are generated? How do I resolve it?

Environment

PPM 15.2PPM 15.3

Resolution

I investigated SimpleDateFormat class and it generated "Unparseable date" messages. 

 

I checked format date from SimpleDateFormat("yyyy/MMM/dd",Locale.XXXXX) for following locale. 

It returned different Month format like as Okt for Germany, 10 for Japan, ott for Italy, etc...

It caused [Unparseable date] and no data was imported by [Tomcat access log import/analyze] job.

It should be Oct like as US locale.

 

----------------

US      = 2017/Oct/02

Germany = 2017/Okt/02

Japan   = 2017/10/02

Italy   = 2017/ott/02

France  = 2017/oct./02

Canada  = 2017/Oct/02

-------------------

 

Work Around:

Set environment parameter [_JAVA_OPTIONS] with [-Duser.country=US -Duser.language=en]

 

Ex) For windows OS

_JAVA_OPTIONS=-Duser.country=US -Duser.language=en
