Viewing and Downloading log files

Summary

Sometimes Wolseley’s Development Teams may require reviewing the Middleware log files to
investigate issues related to Problems or Incidents. Also sometimes it’s just to understand the
behaviour of application during development stages. All these log files are written to backend
servers.

Options

There are couple of ways we can achieve this and in all of them, below are two most popular
methods:

Access to UNIX Servers

Problem with this option is when log files are created or rotated; they will have 740 permissions
which mean user who belongs to any groups other than “oinstall” cannot read those log files.

We can provide full access (777) to existing files, but when these log files are rotated/created
again, they will go back to old (default) permissions.

One way to avoid this is to change “umask” at OS level, but some of Oracle scripts will update
“umask” parameters during runtime. And we would not prefer updating these oracle scripts
manually.

Access Logs from EM Control

Most of Development teams have access to Weblogic Console and Fusion Middleware EM
Control either at minimum Monitor or highest Admin Access.

Oracle already provided an option to view and download current and archived log files from EM
Control. And I think this is the perfect solution to review log files.

Our Recommendation

As it is simple and straight forward option, we recommend using EM Control to review and
download log files.

This document explains the process on how to achieve our recommended method.

View and Download Log Files

 Login to EM Control using your authorized
username and password

 From Navigation Panel (Panel in Left),
expand “Weblogic Domain” and futher
expand “SOA_Cluster” and right-click on
“WLS_SOA1”

 Navigate to “Logs” -> “View Log Messages”

function to search for a particular message.

 On Top right side (just before “Manual Refresh”), you should see “Target Log Files” and

Click on that Button.

 You also have two options i.e. “View Log File” or “Download”.

 To view full log file, select a preferred (log file you want to monitor) log file and click on
“View Log File”

Download Log Files

 To download a Log files, select a preferred (log file you want to monitor) log file and click on
“Download”

 File will be downloaded to you Local Computer. – Please now that if you are on “View Log
File” page for any log file, you can directly download from that page only.

What Type of Files you can View/Download

All kinds of log files we normally see under $DOMAIN_HOME/servers/{serverName}/logs

Ex: Files ending with “.log” extension
 Files ending with “.out” extension
 Diagnostic log files
 Managed Server Access logs
 Domain Logs - Only for Admin Server

What else

You can use this same process for monitoring any log file belongs to any Managed Server.

Ex: Admin Server
 SOA Cluster and Managed Servers
 BAM Cluster and Managed Servers etc.

If you see any issues viewing or downloading, please do not do anything (even if you have Admin
Access) and contact SOA Admin Team with details of issue
