Management of D2000 Applications (Linux)

Management of D2000 applications must be performed as user root

The script <instancedir>/bin/d2app <command> [<appname>] is used for management of D2000 applications

<appname> is the name of the application, if not specified, the script will ask for the application name.

<command> is one of the options:

create

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.

delete

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)? [n]: y

status

gives the information on whether the <appname> application is running and whether it has auto-start set
