This document describes how to administer the EntireX RPC Server for Java, using the Command Central graphical user interface. It covers the following topics:
See also Administering the RPC Server for Java using the Command Central Command Line. The core Command Central documentation is provided separately and is also available under Guides for Tools Shared by Software AG Products on the Software AG documentation website.
Open an Internet browser and specify the URL of the Command Central Server as follows: http://<Command_Central_host>:<Command_Central_port>. This takes you to the Command Central Login page.
On Windows you can also get to the Login page from the Command Central Start Menu entry.
Provide your user credentials in the Login page and click Log In. This takes you to the page Home > Instances:

To configure an RPC Server for Java instance
In the Command Central home page, click the Instances tab.
Click on the link associated with this instance to select the RPC server instance you want to configure.
Click the Configuration tab. EntireX supports the following configuration types, which are presented in a drop-down box when you click the down arrow below the Configuration tab label:
Note:
All configuration changes require a restart of the instance to take effect.
Click
to modify the parameters on your selected configuration type.Click
to check the correctness of your input or to save your changes.The configuration options are described in more detail below:
Parameter | Description |
---|---|
Connection | |
Transport | Transport over TCP or SSL. Default is TCP .
|
Broker host | Required. EntireX Broker host name or IP address. See Using the Broker ID in Applications in the RPC Programming documentation. |
Broker port | Required. Port number in range from 1025 to 65535. |
Encoding | Required. Encoding used for the communication between the RPC server and EntireX Broker. |
SSL trust store | Optional. Specifies the location of the SSL trust store. |
SSL trust password | Optional. The password of the SSL trust store. |
SSL verify server | Optional. The RPC server as SSL client checks the identity of the broker as SSL server. |
FIPS-140 mode | Optional. Enable FIPS-140 compliant SSL communication. Default is no .
|
Credentials | |
User | Optional. The user ID for secured access to the broker. |
Password | Optional. The password for secured access to the broker. |
Here you can specify one or more full paths to your Java server programs.
Parameter | Description |
---|---|
Java Archive or Directory | Required. Classpath to the RPC Server implementation. |
Here you can view/edit the configuration file of the RPC Server for Java.
Here you can view/set the license file in the EntireX installation. For details see Import Product License Keys for Instances or Components under Getting Started with Command Central in the separate Command Central documentation under Software AG Suite & Cross-Product Guides.
Note:
The license file is used for all EntireX instances in this installation.
Here you can modify margins of monitored key performance indicators (KPIs) available for the RPC Server for Java: Active Workers and Busy Workers.
Key performance indicators (KPIs) enable you to monitor the health of your RPC Server for Java. The following KPIs help you administer, troubleshoot, and resolve performance issues:
KPI | Setting |
---|---|
Absolute number of Active Workers | entirex.generic.kpi.1.max=20 |
Critical alert relative to maximum | entirex.generic.kpi.1.critical=0.95 |
Marginal alert relative to maximum | entirex.generic.kpi.1.marginal=0.80 |
Absolute number of Busy Workers | entirex.generic.kpi.2.max=20 |
Critical alert relative to maximum | entirex.generic.kpi.2.critical=0.95 |
Marginal alert relative to maximum | entirex.generic.kpi.2.marginal=0.80 |
Do not change the other properties!
Here you can modify how the RPC Server for Java handles server programs with package names. The package name can be configured
for each IDL library (see library-definition
under Software AG IDL Grammar in the IDL Editor documentation).
Parameter | Description |
---|---|
IDL Library | Optional. IDL library name for server implementation if RPC Server for Java handles these server programs with package names. |
Java Package | Optional. Java package name for server implementation if RPC Server for Java handles these server programs with package names. |
