Solution

Linux

Access the server via ssh and execute the following commands:

Execute commands in strict order to avoid improper application restart. Tomcat service must be started after PostgreSQL for instance.

Centos 8
  1. systemctl stop tomcat9
  2. systemctl stop postgresql-12
  3. systemctl start postgresql-12
  4. systemctl start tomcat9
Centos 7
  1. systemctl stop tomcat
  2. systemctl stop postgresql-9.6
  3. systemctl start postgresql-9.6
  4. systemctl start tomcat
Debian 8 / Ubuntu 14 / Ubuntu 16
  1. systemctl stop tomcat7
  2. systemctl stop postgresql
  3. systemctl start postgresql
  4. systemctl start tomcat7


Debian 9 / Ubuntu 18
  1. systemctl stop tomcat8
  2. systemctl stop postgresql
  3. systemctl start postgresql
  4. systemctl start tomcat8


Debian 10 / Ubuntu 20
  1. systemctl stop tomcat9
  2. systemctl stop postgresql
  3. systemctl start postgresql
  4. systemctl start tomcat9


Check the names of your services before attempting stop and start commands.. Names of Tomcat and PostgreSQL services may differ on different installations. For Example Tomcat may be tomcat6 or tomcat7 and PostgreSQL may be postgresql-9.2 or higher.

1. Stop tomcat
    Double click on Apache Tomcat Properties in system tray. In General tab, click Stop to stop tomcat service.

Version 9.5 of PostgreSQL service in these article is an example. Check which version of this service is installed on your server and use this name in the commands listed above. For example, if you have installed Postgresql 9.4 the command 2b will be net stop postgresql-x64-9.4
