Installing the Agent for Java EE/JMX (SAP NetWeaver)

This page guides you through the installation of an agent in an AE system in which authentication is not used. Additional installation steps are required before the agent can be started and used if you intend to use one of the available authentication methods. For more information, see Agent Authentication.

Tip! This page refers only to the manual installation process. If you want instructions on how to install a containerized Java agent, see Installing Containerized Java Agents.

The Agent creates an additional log file in SAP format. This file is automatically stored in the agent's sub-folder "log" in the installation directory. It can easily be processed with SAP Tools.

Important!

If you use SAP Netweaver 7.50 SPS0 or SPS1, SAP note 2069317 must be implemented. Otherwise, the Agent produces the error java.security.InvalidKeyException: PublicKey algorithm not implemented: ECPublicKey.
If the version of the cryptography provider (IAIK) is 5.2 or lower, you must store trusted certificates in the cacerts file of the JVM. For more information, see SAP note 1877723. In SAP systems in which executables are replicated with sapcpe, make sure to do the changes in the central SAP JVM directory and not only in the instance-specific directories. Otherwise, your changes are overwritten any time the SAP system is restarted.
If the version of the cryptography provider (IAIK) is higher than 5.2, the trusted certificate path can be configured in the configuration file of the agent. For more information, see Agent JMX

Connecting to the Automation Engine

The Automation Engine and the Windows, UNIX, and Java Agents communicate using TLS/SSL. These agents establish a connection with the Java communication process (JCP), which uses trusted certificates to prove their identity to other communication partners.

Important! Make sure you are familiar with the TLS/SSL and certificate implementation before installing and/or upgrading the respective component. For more information, see:

When you used certificates signed by a CA, the certificates are stored in the respective Java or OS store by default; that is the Java trust store for Java components and Java Agents, the Windows OS store for Windows Agents, or the TLS/SSL store for UNIX Agents. In this case, you only have to check that the root certificates already are in the respective store.

If the relevant certificates are not there and you want to import them, you can use OS or Java specific tools for that purpose, such as Keytool, cert-manager, OpenSSL and such. For more information on how to use those tools, please refer to the respective product documentation.

If you do not want to use the default locations for the components and Agents listed above, make sure you use the trustedCertFolder=, agentSecurityFolder=, and keyPassword= parameters (if applicable) in the respective configuration (INI) file to define the path to the folder where the trusted certificates are stored.

Important! TLS/SSL Agents (in containers and on-premises) as well as the TLS Gateway, when used for the Automic Automation Kubernetes Edition, establish a connection to an ingress / HTTPS load balancer, which requires a certificate for authentication.

Make sure that address of the load balancer is defined on both sides: the Automation Engine and the Agent / TLS Gateway and that your HTTPS load balancer has the required certificates in place. For more information, see Connecting to AWI, the JCP and REST Processes Using an Ingress.

Installing the Agent for Java EE/JMX (SAP NetWeaver)

Create a role for the JMX agent in the SAP Identity Management.
- In the General Information tab of the Details section, assign the unique name administrators (as defined in the supplied web.xml file) and a description.
- Click Save.
- In the Assigned Actions tab, type in jmx in the Get: section and click Go.
- Select the line that shows the Name JmxManageAll and click Add and Save.
Set up the JMX agent. To do so, copy the ucxjjmc.sca file to the computer where SAP NetWeaver is installed.
Deploy the JMX agent.
- Login to the SAP NetWeaver host with the operating system user <sid>adm. For more information, see https://help.sap.com/saphelp_hanaplatform/helpdata/en/be/98c998bb5710149e8cace9b0c08908/content.htm.
- Open a telnet to localhost port 50008 if your generated instance is 00, or localhost port 50108 if your instance is 01, and log in as administrator (type: Isc, jump 0).
- Deploy c:\Automic_JMX\ucxjjmx.sca
Undeploy the JMX agent. To do so, open a telnet to localhost port 50008 or localhost port 50108, and log in as administrator (type undeploy name=JMXAgent vendor=automic.com).
Configure the JMX agent.
- Open the browser http://<sap-host>:50000/uc4jmx (instance 00), or http://<sap-host>:50100/uc4jmx (instance 01), and fill in the relevant configuration data.
- Adjust the JMX agent settings to your system environment. The most important settings are:
  - Name of the agent
  - Name of the computer on which the Java communication process is available
  - Port number of the Java communication process
- When you used certificates signed by a CA, the certificates are stored in the respective Java or OS store by default. In this case, you only have to check that the root certificates already are in the respective store.
  
  If you do not want to use the default location for this component, make sure you use the trustedCertFolder=, agentSecurityFolder=, and keyPassword= parameters (if applicable) in the respective configuration (INI) file to define the path to the folder where the trusted certificates are stored.

On the host, before creating jobs, select JNDI in the JMX tab of the Job object. Enter jmx as the object name.
