Management of D2000 applications must be performed as a |
<appname> is the name of the application, if not specified, the script will ask for the application name.
<command> is one of the options:
creates a D2000 application
The application name must be unique across the D2000 instance within the computer. |
[root@localhost bin]# ./d2app create Enter D2000 application name ('?' for list all): app1 Enter application description: My D2000 application Enter application startup parameters: /Capp1 Enter D2000 server listen port: 3119 ======================= Ready to create new D2000 application: Application name: app1 Application description: My D2000 application Startup parameters: /Capp1 TCP listen port: 3119 psql executable: /usr/pgsql-9.6/bin/psql Systemd postgresql service: postgresql-9.6.service -- D2000 instance name: d2000 D2000 installation dir: /opt/d2000 ======================= Proceed (yY|nN)? [y]: |
During creation, enter a description and any additional application startup parameters. If you need to run multiple applications at the same time, change the port so that each has a unique port.
After approval, the application will be created.
Proceed (yY|nN)? [y]: y Creating configuration database...done Creating logfile database...done Application app1 created. Create archive database (yY|nN)? [y]: |
The script will offer the creation of an archive database for the application after approval fill in the name of the archive:
Create archive database (yY|nN)? [y]: y Enter D2000 archive name ('?' for list all) [self]: ======================= Ready to create D2000 archive: Application name: app1 Archive name: self psql executable: /usr/pgsql-9.6/bin/psql -- D2000 instance name: d2000 D2000 installation dir: /opt/d2000 ======================= Proceed (yY|nN)? [y]: y Creating archive database...done Archive database self created. |
After approval, the archive database will be created.
A systemd service with a name in the form d2000-<appname>.service
(in this case it is d2000-app1.service
.) is automatically created for the application.
The application can be started with the script ./d2app start <appname>, see below.
deletes the entire <appname> application and the archives that are part of the application
[root@localhost bin]# ./d2app delete app1 ======================= Ready to delete D2000 application: Application name: app1 psql executable: /usr/pgsql-9.6/bin/psql -- D2000 instance name: d2000 D2000 installation dir: /opt/d2000 ======================= Proceed (yY|nN)?

restarts (stops and starts) the application <appname>
[root@localhost bin]# ./d2app restart <appname> <appname> restarted successfully. |
