Minimum Requirements
Created: | Updated:
z/IRIS Server (a.k.a. IronTap)
The requirements and recommendations below achieve an average processing throughput of 10,000 SMF records per second. Users should adjust the following requirements, as needed, to meet the required SMF processing throughput in each environment.
Hardware requirements
CPU | 4 logical processors |
---|---|
RAM | 4 GB |
Storage | 16 GB |
Software requirements
Recommended Linux distributions | Ubuntu 16.04+, Debian 7+ ImportantSupports operating systems with English language support only. |
---|---|
Java platform | OpenJDK 17 AdoptOpenJDK is recommended |
IronTap Docker image
Recommended Docker version: 20.10+
OpenTelemetry ziris-instrumentation-extension module
IBM Db2 for z/OS JDBC drivers
Compatible version 4 JDBC drivers for IBM Db2 for z/OS version 12 are supported by the z/IRIS Instrumentation Extension for OpenTelemetry Java agents.
IBM documents compatible drivers here.
OpenTelemetry Java agent version
Refer to ziris-instrumentation-extensions versions to find out which ziris-instrumentation-extension release is compatible with your OpenTelemetry Java agent.
z/OS Client
zFS mounted file system
Minimum allocated space | 2000 KB |
---|
Mainframe software requirements
Supported z/OS releases | z/OS 2.1 and later |
---|---|
Required Java platform |
If TLS communication is required for the Kafka Producer, IBM Semeru Runtime Certified Edition for z/OS 11 or 17 MUST be used. |
SMF mode | Logstream SMF Logstream mode is a prerequisite to activate in-memory resources. |
TCPIP | TCP/IP must be active and configured on z/OS. |
Users should ensure that the number of SMF records written to a single SMF in-memory resource will not result in a loss of SMF records due an exceptionally high throughput vs available buffer space.
Apache Kafka
Supported Version | 2.2.0 or newer Apache Kafka provides a bi-directional compatibility policy since version 0.10.2. This means that older versions may work as well. We recommend always using the latest generally available libraries as they include vital security patches and performance improvements. |
---|---|
Throughput Capability | The Apache Kafka Configuration Guide provides system configuration for 10,000 SMF Records/s (~35.000 KB/s depending on the type of records). This configuration would need to be scaled to meet total SMF throughput processing. |
