You can install the Perspectium DataSync for ServiceNow Agent on supported Windows and Linux devices.
Prerequisites
First, make sure that the device you are installing the DataSync for ServiceNow Agent on meets these basic requirements.
You will also need to request the Agent Installer from Perspectium Support.
Procedure
To install the DataSync for ServiceNow Agent, follow these steps:
Open the Agent Installer
Open the Agent Installer .jar file. If you didn't receive this file, you can request one from Perspectium Support. A pop-up may appear indicating that the Agent Installer file can't be opened because it is from an unidentified developer. If this happens, click OK to close the pop-up and then navigate to System Preferences > Security & Privacy. Under the General tab, locate the section beginning with Allow apps downloaded from: and click Open Anyway. Then, click Open in the resulting pop-up to open the Agent Installer wizard.
Accept the End User License Agreement terms
Check the box to accept the terms of the Perspectium End User License Agreement. Then, click Next.
Choose an installation path and JDK/JRE directory
Choose a directory to install the DataSync Agent files in. If you specify a new directory, that directory will first be created and then populated with the Agent files. Then, click Next. On the resulting window, you will be asked to choose the directory where your Java JDK or JRE is installed. In most cases, you can accept the default directory here and then click Next.
NOTE: Your JDK/JRE must be version 1.8.0 or higher.
Choose agent name and replicator type
Type a name for your DataSync Agent; e.g., datasyncforservicenow_to_mysql. Then, choose an option from the Replicator Type dropdown:
| Choose... | If sharing data to a... |
|---|---|
| MySQL_Replicator | MySQL database |
| MSSQL_Replicator | Microsoft SQL database |
| Oracle_Replicator | Oracle database |
Finally, click Next to proceed to the next step.
Enter Perspectium Mesh authentication info
On the resulting page, enter the following to allow your DataSync Agent to authenticate when connecting to the Perspectium Integration Mesh:
| Field | Information to enter |

| Server | Your Perspectium Integration Mesh URL (excluding "http://", "https://", "amqp://", or "amqps://") e.g., us-east-3-dev.perspectium.net |
| User | Username used to connect to the Perspectium Integration Mesh |
| Enter Password | Password used to connect to the Perspectium Integration Mesh
|
| Retype Password | Password used to connect to the Perspectium Integration Mesh |
| Queue Name | Name of the queue that will store data being shared from your ServiceNow instance to your database. Simply replace the yourqueue text here with the name of your ServiceNow instance; e.g., dev12345 |
| Encryption/Decryption Key | A key of 24+ characters (for base64, TripleDES, and AES-128 encryption) or 32+ characters (for AES-256 encryption), including spaces, which will be used to encrypt data being shared from your ServiceNow instance to your database. |
| Max Reads | A maximum number of data messages that your DataSync Agent will read from the queue each time messages are processed |
| Polling Interval (sec) | Time period (in seconds) for which your DataSync Agent will process messages from your shared queue |
Then, click Next to continue to the next step.
Enter ServiceNow and database connection info
On the resulting page, enter the following information to allow your DataSync Agent to connect to and authenticate with your ServiceNow instance and database server:
| Field | Information to enter |
|---|---|
| Instance | Your ServiceNow instance URL (excluding "http://" or "https://") |
| User | Username used to log into your ServiceNow instance (in firstname.lastname format) |
| Enter Password | Password used to log into your ServiceNow instance |
| Retype Password | Password used to log into your ServiceNow instance |
| Server | Server URL for the database you will be sharing your ServiceNow instance data to (excluding "http://" or "https://") |
| Port | Port number for your database |
| User | Username used to log into your database |
| Enter Password | Password used to log into your database |
| Retype Password | Password used to log into your database |
| Database | Name of your database schema |
Then, click Next to continue to the next step.
Review and finish installation
On the Summary and Review screen, wait for the processes to finish running and then click Next. Then, on the Perform External Processes screen, wait for the processes to complete and then click Next.
Finally, on the Installation Finished screen, click Done to finish installation of your DataSync Agent.
NOTE: Optionally, you can Generate an automatic installation script on this screen and then choose a directory to save your install script in. This script can then be run on another device to install a DataSync Agent with the same settings you've specified here.
The following system files will be installed within the bin/perspectium_data directory and used for temporary storage/caching when your DataSync for ServiceNow Agent is running:
- psp.in.agent.errors
- psp.in.messageset
- psp.out.servicenow.INSTANCE_NAME (where INSTANCE_NAME is from your https://INSTANCE_NAME.service-now.com URL)
- psp.in.servicenow
- TableStatsPublisher
A perspectium.log file will also be installed that contains important log messages for your DataSync for ServiceNow Agent. For more information, see monitoring DataSync Agent logs.
NOTE: If the files listed above exceed 1 GB in size, you may delete these files to improve your DataSync Agent performance.
(Optional) Validate your Agent configuration
After installing your DataSync for ServiceNow Agent, it is highly recommend to confirm that you Agent is configured correctly by running the Agent validateConfiguration tool.
To run the validateConfiguration tool on a Linux device, open a terminal window and change your current directory to the directory where you installed your DataSync for ServiceNow Agent files. Then, change your current directory to Perspectium_Replicator_Agent and execute the following command:
bin/validateConfiguration start
To run the validateConfiguration tool on a Windows device, navigate to the bin directory that was installed within the main Agent directory that was specified in Step #3. Then, double-click to run the validateConfiguration.bat file.
