Manual database configuration

When the user chooses to configure database later it is mandatory to edit the application.conf configuration file and set the required database parameters before the server can be started. Configuration file is located under /opt/DispatcherParagon/conf directory. It can be opened using remote SSH utilities such as MobaXTerm or directly from Linux shell using any of the available editors, for example vi or nano.

Find the following section in the configuration file:

There are two sets of database parameters that must be configured: one for the server configuration settings (eopng_config) and another one for reporting purposes (eopng_documents). This setup requires two databases (or database instances) to be created on the target database cluster by database administrator. Make sure they are created before continuing with Dispatcher Paragon Cloud server configuration.

Database url parameter

• For MS SQL Server enter the following URL (in double quotes):

jdbc:sqlserver://SERVERADDR:PORT;database=DBNAME;authentication=SqlPassword

where SERVERADDR is the database address, PORT is the port number (1433) and DBNAME is one of eopng_config or eopng_documents. Make sure both of them exist on the database cluster. More information is available at the following link: Microsoft JDBC driver

• For PostgreSQL server enter the following URL (in double quotes):

jdbc:postgresql://SERVERADDR:PORT/DBNAME

where SERVERADDR is the database server address, PORT is the port number (5432) and DBNAME is one of eopng_config or eopng_documents which must exist on the target database. For information is available at the following link: PostgreSQL JDBC driver

Database username parameter

Enter a user name of the database user. The user must have permissions to read, write and modify database schema.

Database password parameter

Enter a password for the user in clear text. It will be automatically encrypted by the server.

SSL configuration for database cluster and Dispatcher Paragon Cloud server

Please refer to vendor-specific documentation on how to configure a particular database for SSL connectivity.

If SSL connection is required to the database cluster and the database server certificate is not signed with a globally trusted CA root certificate it will be necessary to add a custom CA root certificate to the server’s trust store. To do that:

• Prepare a CA root certificate in the DER or PEM format

• Copy this certificate to the target server

• Import it into the server’s trust store by running the following command (as a root user or with sudo prefix):

/opt/DispatcherParagon/jre/bin/keytool -importcert -file /path/to/cacert.cer -alias db-cert -keystore /opt/DispatcherParagon/conf/truststore

When prompted for a trust store password enter changeit.
When prompted whether to trust a new certificate type yes and press ENTER.
