Linux - catalina.pid

dranakan

Hello,

If the server Linux crash and restart, Alfresco will not start because the PID file exists.

service alfresco restartUsing CATALINA_BASE:   /opt/Alfresco/tomcat
Using CATALINA_HOME:   /opt/Alfresco/tomcat
Using CATALINA_TMPDIR: /opt/Alfresco/tomcat/temp
Using JRE_HOME:        /opt/Alfresco/java
Using CLASSPATH:       /opt/Alfresco/tomcat/bin/bootstrap.jar
PID file (/opt/Alfresco/tomcat/temp/catalina.pid) found but no matching process was found. Stop aborted.
/opt/Alfresco/tomcat/scripts/ctl.sh : tomcat could not be stopped
‍‍‍‍‍‍‍‍

Why this has been done like this ? Could be not better to automaticly remove this file and write a message in the logs ?
Could I add a command to remove this file in /etc/init.d/alfresco before the start of alfresco without risk ?

Thank you.

It's Tomcat's implementation. You could run on another AS if this bothers you.

You can safely remove the PID file after a crash.

Its probably best not to automatically delete the pid file since it will act as a lock to prevent concurrent instances.

Thank you mrogers,

I think the best is to create a script "remove catalina.pid" which start before alfresco. (put links to this script in /etc/rc.d/rc3.d/ et /etc/rc.d/rc5.d/).
