Agent Requirements

These are the requirements needed to ensure that your agent can be executed properly and has the ability to be upgraded in the future.

System

System Requirements
Memory	8GB minimum
Processor Cores	4 minimum
Hard Disk Space	100GB minimum
Network Interface	GigE

Network Access

The Replicator agent requires only outbound access to the Perspectium cloud and the ServiceNow instance.

Perspectium products require that your firewall settings allow traffic to and from your Perspectium MBS. This can be through any one of the following three ports: AMQP, AMQPS, or HTTPS. You will specify which protocol you will be using through the URL of the <message_connection>.

The Agent also requires that your firewall settings allow traffic to and from your ServiceNow instance. To test this access you can consult this page.

Network Requirements
AMQPS Outbound Port	TCP/5671 outbound to your Perspectium MBS (amqps://example.perspectium.net)
AMQP Outbound Port	TCP/5672 outbound to your Perspectium MBS (amqp://example.perspectium.net)
HTTPS Outbound Port	TCP/443 outbound to your Perspectium MBS (https://example.perspectium.net)
HTTPS Outbound Port	TCP/443 outbound to your ServiceNow instance

Java

Both 32 and 64 bit versions of Java are supported. The Java version must be 1.7 or 1.8. It's strongly recommended that you use a server type JVM instead of a client or desktop version.

A 32 bit version of Java is required if you're running the agent on a Windows server for Agent versions under 3.24.0.

You can determine that Java is in your current path and the version by issuing the following command from the command prompt:

java -version

If you don't see something like the following then please contact your system administrator for help.

java version "1.7.0_65"

Make note of the path to Java. One way to determine the path to Java on most linux distros is to issue the following command:

which java

On Windows this is typically located in “C:\Program Files \Java\…”

On either windows/linux the installer will generally find the path to the java installation and auto-fill this for you.

Verify that Java is in your PATH system (environment) variable as some installations of Java may not add it properly. If it is not there, add the path of the JRE's bin direct as indicated here.

Supported Databases

Database	Version
Oracle	12c Release 1: 12.1.0.2+
SQL Server (MSSQL)	2012+, 2016 recommended
MySQL	5.7.22 or older
SAP Hana	SPS 12+
Amazon Redshift	4.0-4.1
Amazon Aurora (MySQL compatible)	N/A
IBM DB2	11+
HP Vertica	8.0+
PostgreSQL	42.1.4

Note: Perspectium uses the newest version of each of the associated JDBC driver,which is included 
      with the install.
      
Note: Perspectium strongly recommends placing the agent on the same local area network as the database server.
