Below are the minimum requirements and recommendations for optimal z/IRIS processing.

z/IRIS Linux Server (a.k.a. IronTap)

Requirements and recommendations below should achieve a processing throughput of circa 10.000 SMF records per second. Users should adjust the below requirements as needed to achieve the required SMF processing throughput in each environment.

Hardware requirements 


Quad Core Processor (2,5 GHz) x86_64 compatible (e.g.: Intel® Core™ i5-2400S Quad-Core Processor 2.5 GHz, Intel® Core™2 Quad Processor Q8300, AMD A6-6310 Quad-Core Processor or higher)

Storage10 GB

Software requirements

Recommended Linux distributions

Ubuntu 16.04+, Debian 7+


Use the English version of the OS.

Recommended Java platformOpenJDK 8 or Oracle Java 8 JDK

z/OS Client

zFS mounted file system

Minimum allocated space2000 KB

Mainframe software requirements

Supported z/OS releasesz/OS 2.1, z/OS 2.2, z/OS 2.3, z/OS 2.4
Required Java platformIBM SDK, Java Technology Edition, Version 8 64 Bit
SMF mode

At least 1 SMF in-memory resource must be defined for any SMF record types that will be streamed via z/IRIS. 

SMF Logstream mode is required to activate SMF in-memory resources.

TCPIPTCPIP must be active and configured on z/OS.

Depending on SMF record sizes and SMF record type generation frequency, users should ensure that the number of SMF record types in a single SMF in-memory resource will not result in a loss of SMF records due an exceptionally high SMF in-memory wrap-around rate.
