In this article, we present the Java-based agents for Windows and Linux. This innovation brings a number of changes and new functions, which we will discuss in detail throughout the article.

What will change with the Java-based agents?

  • Farewell to 32-bit support One of the biggest changes concerns operating system support. The new Java-based agents are designed exclusively for 64-bit systems. This means that a 64-bit host is required to install the new agents.
  • Installing the Java Runtime Environment (JRE) As the agents are now Java-based, a Java runtime environment is required. The good news is that an automatic installation by Automic is possible. This means that the JRE is installed by Automic via the CAU (Centralised Agent Upgrade). In order to do this, you must install the JRE package in Client 0.

New functions of the Java-based agent

  • Unicode Support One of the most prominent new features of version 24 is the Unicode support. To be able to use UTF-8 in the jobs, the agent must support Unicode. This is only the case with the Java-based V24 agents. The agent configuration file contains the "utf8" parameter, which can be used to specify whether Unicode or the standard code page should be used.
  • Sending e-mails via SMTPS The new Java-based OS agents offer the option of sending emails via SMTPS. Previously, this was only possible using the engine. Now this function can also be utilised by other agent types.
  • Privilege separation for Linux agents
  • Now Linux agents have a different privilege separation. With the new Java-based agents, there is no longer a separate listener process. The agent runs under the agent user after starting.
  • Improved connection status The new Java-based agents show you the connection status in the ServiceManager. You can now also see whether the agent is connected or not.
  • Security feature: PAM Limits Another security feature is the introduction of the ‘use_limits’ parameter inside the INI file. This allows you to control how many sub-processes a job can start or how much CPU it can consume. This makes your agents safer and more controllable.

Conclusion about Java-based OS Agents

The new agents offer many improvements, for example better Unicode support, secure e-mail sending options and enhanced security functions. Good luck with the new Java-based agents!
