Stopping/Restarting/Starting a FineDataLink Project

Application Scenario

• After manually upgrading FineDataLink, you need to restart the project.

• After modifying a certain configuration of the FineDataLink project, you need to restart the project.

Function Description

This document describes how to stop and restart the FineDataLink project in the Linux system.

Function Description

1. For FineDataLink projects deployed in Tomcat, WebLogic, or WebSphere containers, you can stop them by stopping the container.

Note:

The methods provided in this article apply to all JAR versions.

2. If there are pipeline tasks in the FineDataLink project, you need to pause the pipeline tasks before restarting the FineDataLink project.

In this example, the project is deployed in /home/wendy/FineDataLink/tomcat-linux.

Stopping the Project

1. Execute the following command to check the project processes. You will find that the current server is running, with process IDs 14429 and 13878, as shown in the following figure.

ps -ef|grep tomcat-linux

2. Kill the project process, and check whether there are unclosed project processes. All processes related to this project need to be killed.

Note:

You are not advised to use the kill -9 pid command, as it may cause abnormalities in pipeline tasks.

kill 14429
kill 13878

After using the command above, you can wait for half a minute, and then use the command ps -ef|grep tomcat-linux again to check if the process has been closed.

Restarting the Project

1. Enter the bin directory of the project, and then restart the project, as shown in the following figure.

Note:

If the FineDataLink project is running on a Linux system, restarting the project requires root privileges.

cd /home/wendy/FDL/tomcat-linux/bin
./startup.sh

2. Check the real-time log. If the consumed time is displayed in the real-time log, it means that the project has been restarted successfully, as shown in the following figure.

Method One:

cd /home/wendy/FDL/tomcat-linux/logs
tail -f catalina.out

Method Two:

tail -f /home/wendy/FDL/tomcat-linux/logs/catalina.out
