2.2.10 How to delete the Dlog4j2.formatMsgNoLookups parameter

This manual will guide you on how to delete the Dlog4j2.formatMsgNoLookups parameter on a Linux server.

This deletion is required only if you are installing quilliup version 2.6.7 and up, and the parameter exists.

First, check if the parameter exists in file setenv.sh:

cd /opt/tomcat/bin

If Exists, follow the next steps:

1. Go to the bin folder:

cd /opt/tomcat/bin

2. Check quilliup's status:

ps -ef | grep tomcat

3. Stop quilliup's service:

sudo kill -9 XXXX

For example, XXXX= 785 (near the tomcat):

4. Delete log files:

Go to the logs folder:

cd /opt/tomcat/logs/

Delete the contents of the folder:

(Make sure you are inside the logs folder)

sudo rm -rf *

Note: run the 'ls' command to clarify the deletion.

5. Delete the Catalina folder:

Go to the work folder:

cd /opt/tomcat/work/ 

Delete the contents of the folder: (Make sure you are inside the work folder):

sudo rm -rf /opt/tomcat/work/ *

Note: run the 'ls' command to clarify the deletion.

After stopping the service, please continue to the upcoming steps:

6. Back up the current setenv.sh file, which are located in:

Please delete the parameter:-Dlog4j2.formatMsgNoLookups=true; from the next
row:

export JAVA_OPTS="$JAVA_OPTS -server -Xms4096m -Xmx4096m -XX:MaxMetaspaceSize=256m -XX:+CMSClassUnloadingEnabled -Dlog4j2.formatMsgNoLookups=true"

8. Start quilliup's service:

a. Go to the bin folder:

cd /opt/tomcat/bin

b. Start quilliup's service:

sudo ./catalina.sh start

c. Check that the service is up (stay in the bin folder):
