ibi™ Open Data Hub for Mainframe Connectors 1.0.8

# z/OS Installation Requirements

Before you install, review the following requirements.

Type | Description
--- | ---
Operating System | z/OS 2.1 or higher The TIBCO WebFOCUS® Release Notes ibi™ Release Notes maintains a current list of supported operating systems and levels.
Disk Space | For USS Deployment, approximately 6 GB, however, about double the space is needed during installation. For PDS Deployment, approximately 1555 cylinders of 3390 disk for HOME data sets.
IP Ports | Up to six consecutive IP ports (two in reserve for typical extra features). Additional Java Listeners (post-installation option) require additional ports (beyond basic reserve).
Java | Java JRE or Java SDK (also known as JDK) 8 or higher. Used for Java-based adapters, server-side graphics, XBRL, or user-written CALLJAVA applications. For additional information, see JVM Requirements for Java Services (Server Installations Only). Note: Java 8 and Java 11 are explicitly tested and certified to be compatible with the WebFOCUS Reporting Server. Other Java releases may be compatible with the WebFOCUS Reporting Server. If you use an untested Java release, you must self-certify its compatibility with the WebFOCUS Reporting Server and accept responsibility for using an untested release.
Memory Common framework plus per agent memory. | Per Agent 20 MB Common Framework 500 MB
Web Browser | Needed for using the WebFOCUS Reporting Server browser interface. Microsoft Edge Mozilla Firefox® 59 or higher. Google Chrome® 65 or higher.

# JVM Requirements for Java Services (Server Installations Only)

The minimum Java JVM release level is 8 or higher, due to required internal components of the server. As already noted, only Java release 8 and release 11 are explicitly tested, and use of any other release must be self-certified by the customer if they choose to not use release 8 or release 11. The Java Listener will not start properly (and will show errors in the edaprint.log file) if 8 (or higher) is not in use.

When a server starts, it adds search directories based on JDK_HOME or JAVA_HOME variables. If JVM is found with the correct bit size and level (8+), the Java Listener will start, send a start message to the edaprint.log file, and no further configuration is needed.

If JVM loading fails, the server will start, but this should be corrected by setting JDK_HOME or JAVA_HOME to a respective home directory for a Java that matches the required bit size and release level. If both values are declared, JDK_HOME will be used. Set the environment variable in the server EDAENV environment file.

For example:

    JDK_HOME=/usr/java/64/jdk1.8.0_341
