PostgreSQL SSL Integration Guide

review the following guide for setting up an integration between manufacturing connect edge and a postgresql database using ssl authentication before you begin you will need the following access to a postgresql database that uses ssl authentication the ca certificate and any other required authentication parameters to access the database refer to the following links to learn more postgresql docker image postgresql documentation secure tcp/ip connections with ssl step 1 add device follow the steps to connect a device docid\ rfvijdxz7dbad8mwbisma the device will be used to store tags that will be eventually used to create outbound topics in the connector make sure to select the enable data store checkbox step 2 add tags after connecting the device in manufacturing connect edge, you can add tags docid\ ioanzd2awqnkuppgee3eh to the device create tags that you want to use to create outbound topics for the connector step 3 add the db postgresql connector follow the steps to add a connector docid 8xiuwwbo25vvjsofayemk and select the db postgresql ssl provider configure the following parameters name enter a name for the connector hostname enter the hostname for the postgresql database port the postgresql server port the default value is 5432 ssl mode select the ssl mode (require, verify ca, verify full) ca certificate paste the ca certificate associated with the database for manufacturing connect edge version 3 10 0 and later, you have the option to upload the certificate certificate paste the ssl certificate for manufacturing connect edge version 3 10 0 and later, you have the option to upload the certificate private key enter or paste the ssl private key username enter the appropriate username password enter the password for the username database enter the database name table enter the table name show mapping if you want to send data to a custom table, select this checkbox and unselect create table see work with tables in sql connectors (create table and show mapping) docid\ afktzpwdwwp2trlxgohbz to learn more to add key/value pairs for the custom table, see work with tables in sql connectors (create table and show mapping) docid\ afktzpwdwwp2trlxgohbz create table if you want to send data to an existing table in the default format, or you want to create a new table in the default format, select this checkbox and unselect show mapping see work with tables in sql connectors (create table and show mapping) docid\ afktzpwdwwp2trlxgohbz to learn more commit timeout enter the transaction commit timeout in (ms) max transaction size enter the maximum number of messages before a transaction is committed, regardless of timeout parameter throttling limit the maximum number of messages per second to be processed the default value is zero, which means that there is no limit persistent storage when enabled, this will cause messages to undergo a store and forward procedure messages will be stored within manufacturing connect edge when cloud providers are online queue mode select the queue mode as lifo (last in first out) or fifo (first in first out) selecting lifo means that the last data entry is processed first, and selecting fifo means the first data entry is processed first step 4 enable the connector after adding the connector, click the toggle in the connector tile to enable it if you see a failed status, you can review the manage connectors docid\ slflfyqo1irgdr y0rxzc and relevant error messages step 5 create topics for connector you will now need to import the tags created in step 2 as topics for the postgresql connector the topics will be created as outbound topics to create outbound topics click the connector tile the connector dashboard appears click the topics tab click the import from devicehub tags icon the devicehub import dialog box appears select all the tags to import and click import after adding all required topics, navigate to the integration overview page and ensure the connector is not disabled and still shows a connected status step 6 enable topics to enable the topics, return to the topics tab and click the enable all topics icon step 7 make postgresql queries you can now verify that you can view data in the postgresql database update the credentials, database name, and table name to your specific configurations to make postgresql queries from the postgresql terminal window, enter psql h locahost u postgres and press enter the psql (13 2 (debian 13 2 1 pgdg100+1)) version number appears enter \l and press enter the list of databases appears in the console enter \l db example and press enter the list of databases shows only db example enter \c postgres and press enter you are now connected to database "db example" as user "postgres" appears enter \dt and press enter the list of relations appears showing the devicehub schema enter \d devicehub and press enter the public devicehub table appears enter select from devicehub; and press enter the data for the devicehub table appears
