You can configure your DataSync Agent to share data from ServiceNow or Salesforce to a PostgreSQL database by changing some additional configurations in your agent.xml file.
Prerequisites
First, you will need to Install the DataSync Agent.
You will also need to create a ServiceNow dynamic share/bulk share.
Make sure to stop running your DataSync Agent before making any Agent configuration changes.
Finally, you will need to create a database in PostgreSQL that will store data replicated via the DataSync Agent.
Procedure
To set up your DataSync Agent to share application data to a PostgreSQL database, follow these steps:
Add the latest PostgreSQL JDBC driver to your DataSync Agent's extlib directory.
Follow the steps to Install the DataSync Agent or the DataSync Agent for Salesforce and make sure that your agent.xml file is configured correctly.
Navigate to the directory where you saved your agent.xml file when installing your DataSync Agent.
Open your agent.xml file in a text editing application. Then, locate the <task> directive(s) within your <subscribe> directive, and update the following database-related directives:
| Directive | Value to enter | Required? |
|---|---|---|
| <database_type> | postgresql | Yes |
| <database_server> | URL/IP address for your PostgreSQL database | Yes |
| <database_port> | 5432 | Yes |
| <database_user> | Username used to access your PostgreSQL database | Yes |
| <database_password> | Password used to access your PostgreSQL database | Yes |
| <database_parms> | Optional database parameters for the connection string used to connect to PostgreSQL. For example, if you want to use the schema psp_schema, you would specify: <database_parms>currentSchema=psp_schema</database_parms> | No |
Still within the <subscribe> → <task> directive(s), nest the following directive:
Directive | Description |
|---|---|
| <skip_database_creation/> | Bypasses the dynamic creation of the replicated database
|
NOTE:Your agent.xml file should look similar to the example shown below:
<?xml version="1.0" encoding="ISO-8859-1" standalone="no"?>
<config>
<agent>
<share>
</share>
<subscribe>
<task instances="1">
<task_name>test_postgresql_subscribe</task_name>
<message_connection password="encrypted:vlOtU71yu8N/EFIJH85SSBtaIt7qEEfvqiqft9VZyYE=" user="exampleuser" queue="psp.out.replicator.example">https://example.perspectium.net</message_connection>
<instance_connection password="encrypted:vlOtU71yu8N/EFIJH85SSBtaIt7qEEfvqiqft9VZyYE=" user="example.user">https://myinstance.service-now.com</instance_connection>
<handler>com.perspectium.replicator.sql.SQLSubscriber</handler>
<decryption_key>The cow jumped over the moon</decryption_key>
<database_type>postgresql</database_type>
<database_server>localhost</database_server>
<database_port>5432</database_port>
<database_user>exampleuser</database_user>
<database_password>examplepassword</database_password>
<database>psp_db</database>
</task>
</subscribe>
<max_reads_per_connect>4000</max_reads_per_connect>
<polling_interval>5</polling_interval>
</agent>
</config>
Save the changes you made to your agent.xml file and close the file.
After configuring your agent.xml file to support replication to your PostgreSQL database, start running your DataSync Agent again.
