System Directories and Logs

h2. Locating Files and Directories

The following table shows the location of some directories that may be needed to effectively work with LucidWorks Enterprise. These paths are all relative to the "LWE Home" directory ({{$LWE_HOME}}) which is specified when running the [installer|lweug18:Installation].

| Solr Source Code | {{$LWE_HOME/solr-src/}} \\ |
| Start/Stop Scripts | {{$LWE_HOME/bin/}} |

\\
{note:title=Editing Configuration Files on Windows}
LucidWorks Enterprise holds configuration files open after reading them, which may cause problems on Windows systems that do not allow editing open files. In this case, stop LucidWorks Enterprise before editing files on Windows to be sure the edits are saved properly.

h2. System Logs

LucidWorks Enterprise records system activities to rolling log files located in the {{$LWE_HOME/logs}} directory of the installation. The table below describes the main purpose of the various log files.

The LucidWorks Enterprise Core log is configured by a properties file ({{$LWE_HOME/conf/log4j.xml}}). The default is to create a distinct log per date (server time). Only data from the most recent {{core.YYYY_MM_DD.log}} file is included in query and index history calculations that appear in the Admin User Interface.


{note:title=Rotation of the ui.log File}
On Windows machines, log rotation of the ui.log file only has been disabled. The LWE Core log will still be date specific, but the ui.log will need to be manually rotated.
