Summary
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 an average processing throughput of 10,000 SMF records per second. Users should adjust the following requirements as needed to achieve the required SMF processing throughput in each environment.
Hardware requirements
| CPU | 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) |
|---|---|
| RAM | 2 GB |
| Storage | 10 GB |
Software requirements
| Recommended Linux distributions | Ubuntu 16.04+, Debian 7+ Compatible with virtual machines. Important Supports operating systems with English language support only. |
|---|---|
| Java platform | OpenJDK 11 AdoptOpenJDK is recommended |
z/OS Client
zFS mounted file system
| Minimum allocated space | 2000 KB |
|---|
Mainframe software requirements
| Supported z/OS releases | z/OS 2.1, z/OS 2.2, z/OS 2.3, z/OS 2.4 |
|---|---|
| Required Java platform | IBM 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. |
| TCPIP | TCP/IP 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.
Apache Kafka
| Supported Version | 2.1.0 or newer Since version 0.10.2 Apache Kafka provides a bi-directional compatibility policy. 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 | 10.000 SMF Records/s (~35.000 KB/s depending on Record Type) |
Supported SMF records
| SMF Type 30 (1-6) | Common Address Space Work records used to create z/OS Work Traces for partner APM ISVs. |
|---|---|
| SMF Type 70 | Mainframe processor utilization |
| SMF Type 101 | Db2 (v11, v12) for z/OS accounting records. See Distributed Db2 trace streaming for APM integration for more details. |
| SMF Type 102 | Db2 (v11, v12) for z/OS performance records. See Distributed Db2 trace streaming for APM integration for more details. |
| SMF Type 123 version 1 and 2 | z/OS Connect auditInterceptor records |
Distributed Db2 trace streaming for APM integration
| Db2 for z/OS Releases | Db2 for z/OS v11, Db2 for z/OS v12 |
|---|---|
| SMF Record Types | 101-102 |
| Supported JDBC Features | JDBC 4.0 |
| Supported IFCIDs | 3 (TRACE(ACCTG) CLASS(1-3)) 172 (TRACE(PERFM) CLASS(30-32)) 58-66 (TRACE(PERFM) CLASS(30-32)) |
