To enable log rotation for tomcat-stdOut.log on 19.2

Hi Julie,

I assume that your servers are running on Windows OS.

Start the tomcat manually using start-appserver.bat and you may find some error messages which will help you to find the issue.

Make sure that the latest MS Visual C++ Redistributable is installed on the server. If not download and install it on the server and try to start again.

Hi Edwin, What's the solution for Linux box ?

Hi Sunil,

Check whether the Apache's rotatelogs is available or not in the environment. If not, install it using any package manager available in your environment. It is available as a part of apache2-utils. 

Hi Edwin, Let me check on that. Thanks for your support.

If already available and if the logs are not rotating, then open the start-appserver.sh and provide the path of the rotatelogs program. Appian will use that to rotate the log files.

On Ubuntu, I use Logrotate.

Create the following file: /etc/logrotate.d/appian-tomcat

Paste the following:

/<APPIAN_HOME>/logs/tomcat-StdOut.log{ 
    copytruncate 
    daily 
    rotate 30 
    compress 
    missingok 
    size 100M 
}

To perform a manual rotation:

logrotate -vf /etc/logrotate.d/appian-tomcat
