The ready-to-run agent is a zipped file that makes it possible to run the agent without the usual installation process. Setting up the configuration for agent will instead be done on ServiceNow through the Ready to Run UI page. It is recommended to have the configuration set and downloaded from ServiceNow before unzipping the agent.
NOTE: This is not the standard installer, which can be read Agent Installation. This is for the “Ready to Run” to simplify the install. It will require the config to be imported rather than being generated by the installer.
Download
First off, you need to download perspectium-replicator-windows_jaz.zip. Contact support@perspectium.com if you have not received this file - this is the file you need to run the agent without the usual installation process.
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.
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 Java 8 or higher. As of the Fluorine release, Java versions 9 and 10 are supported. 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 "1.8.0_181"
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 | 11g, 12c Release 1: 12.1 - 12.2.0.1.0 |
SQL Server (MSSQL) | 2012, 2016 recommended |
MySQL | 5.6 - 8.0 supported in Europium |
SAP Hana | SPS 12 |
Amazon Redshift | 4.0-4.1 |
Amazon Aurora (MySQL compatible) | N/A |
IBM DB2 | 11 |
HP Vertica | 8.0 - 9.21 |
PostgreSQL | 42.2.6 |
Snowflake | 3.9 |
NOTE: Perspectium uses the newest version of each of the associated JDBC drivers, which are included with the install.
NOTE: Perspectium strongly recommends placing the Agent on the same local area network as the database server.
Supported Operating Systems
The following OS versions are supported by the Replicator Agent:
OS | Version |
---|---|
Windows Professional & Home | 7 - 10 |
Windows Server | 2012 - 2016 |
Linux Ubuntu | 14.04 and 16.04 |
Setting Up the Agent
As shown above, the following zipped folder should be downloaded. You may open it and extract it to a desired directory.
Inside the zipped folder should have the following directories. After extraction, make sure that the destination of the extraction has each of the following directories and files as shown above.
In the bin folder lies the necessary files in order to run and execute processes, such as the agent and configuration validation.
The conf folder houses files for configuration. The agent.xml is used to declare endpoints and settings for the agent.
Validating Your Configuration
After the initial set up, you can look at your configuration within the agent.xml file of the conf directory. Here you will see a generic task set up with the credentials you have just input. You can either run it now, however, it is recommended to run our tool to test and validate your current connections. It will run through your Message Bus Connections, Database Connections, and Instance Connections (to ServiceNow or elsewhere) as you have prescribed.
Following these connections it will notify you which pieces failed as well as other diagnostic information about your current configuration.
Installation as a Service
To ensure the Replicator agent runs all the time we'll want to do a few simple tasks to ensure that it will be automatically started when the computer is started. You should also validate that the Agent is working fully before installing it as a service.
Validation
Run the ValidateConfiguration tool to ensure that the Replicator agent will run after making the necessary configurations.
These bat files may need to be run by someone with administrator privileges and you will be prompted to verify that the command should be run as administrator.
You may want to test run the Agent by executing the agent.bat file. This will run the Agent within a command window. Once you close the window the Agent will stop.
Installation
Right click on the file installService.bat and select Run as Administrator to install the agent as a service. It will not function properly if you do not “Run as Administrator”.
That's it for the installation. You can then use the startService.bat or stopService.bat to stop and start the service. You could also use the Windows Services tool. This service will be given the service name specified in the installer and the display name “Perspectium Replicator Agent”. You do not need administrator privileges to Start / Stop the Agent service once it is installed.
Installing Multiple Agents
The name of the agent can be specified in the agent.xml and wrapper.conf. When using multiple agents, they may be differentiated by their names.
For the agent.xml, search for the following line and enter the desired name for your agent:
<task_name>name_example</task_name>
As for the wrapper.conf, the name can be search for the following line of code:
# Name of the service wrapper.ntservice.name=name_example
If you want to install multiple agents as services on the same machine, you will need make sure that each Agent has a unique wrapper.name as the Service Name.
