Operating Systems		Red Hat Enterprise Linux (RHEL) V3.0 with Update 2 Red Hat Enterprise Linux (RHEL) V4.0 or later update [see note 11] Red Hat Enterprise Linux (RHEL) V5.0 [see notes 6 and 11] Red Hat Enterprise Linux (RHEL) V5.1 and V5.2 [see notes 10 and 11] Red Hat Enterprise Linux (RHEL) V5.3 [see notes 11 and 13] SUSE Linux Enterprise Server (SLES) V8 with SP3 or later SUSE Linux Enterprise Server (SLES) V9 with SP1 or later SUSE Linux Enterprise Server (SLES) V10 with SP1 or later [see note 6] SUSE Linux Enterprise Server (SLES) V11 or later [see note 13]
Hardware Requirements		Linux for zSeries platform: IBM S/390 or zSeries (or equivalent) processor, capable of running the required level of a compatible operating system with enough storage to meet the combined requirements of the programming prerequisites, WebSphere MQ, the access methods and the application programs.
Java and JMS Client		IBM SDK Java 2 Technology Edition for Linux on zSeries V1.4.2 (supplied with WebSphere MQ) IBM 31-bit SDK for Linux on zSeries, Java 2 Technology Edition V5.0 (SR1 or above) [Only if the JDK is supplied with another IBM product] IBM 31-bit SDK for Linux on zSeries, Java 2 Technology Edition V6.0 (SR3 or above) [see note 12]
Databases		Where IBM WebSphere MQ is acting as the transaction manager. IBM DB2 Universal Database V8.2 IBM DB2 V9.1 for Linux, UNIX, and Windows (JDBC/XA not supported) [see note 6] Informix Dynamic Server (IDS) V9.40 with Client SDK V2.90
Compilers		GNU C Compiler (gcc) and g++ V2.95 [see note 9] GNU C Compiler (gcc) and g++ V3.2 GNU C Compiler (gcc) and g++ V3.3 GNU C Compiler (gcc) and g++ V3.4 [see note 9] GNU C Compiler (gcc) and g++ V4.1 [see note 9] Micro Focus Server Express V4.0 (COBOL) Micro Focus Server Express V5.0 (COBOL) Micro Focus Server Express V5.1 (COBOL) [see note 14]
Connectivity		TCP/IP (IPv4 and IPv6 provided by the operating system)
Transaction Manager		Where one of these products is acting as the transaction manager and IBM WebSphere MQ is acting as a resource manager, it's recommended that you contact the transaction manager vendor in the first instance for support. IBM WebSphere Application Server V5.1 (for SLES V8 only) IBM WebSphere Application Server V6.0.1 or higher [see note 2] IBM WebSphere Application Server, including the WebSphere Application Server client container, V6.0.2 (see this document for more information) IBM WebSphere Application Server, including the WebSphere Application Server client container, V6.1 (see this document for more information) IBM WebSphere Application Server, including the WebSphere Application Server client container, V7.0 (see this document for more information). BEA Tuxedo V8.1 (for SLES V8 only) BEA WebLogic Server 8.1 + SP4 on RHEL 3.0 or SLES 9 and IBM 1.4.2 JDK to support EJB's (including MDB's) and JMS only.
SOAP Support		IBM SDK Java 2 Technology Edition for Linux on zSeries V1.4.2 (supplied with WebSphere MQ) Apache Axis V1.1 (supplied with WebSphere MQ)
Cryptography Cards		Refer to the Cryptography Card List for WebSphere MQ v6 and v7 document for further information.

Notes:

1. JDBC/XA usage is not supported on this platform.
2. Where higher levels of WebSphere Application Server V6 are suggested, this only includes V6.x levels and does not include other product versions.
3. The WebSphere MQ for Linux (zSeries) product only provides 32-bit MQ APIs however it is supported on 64-bit OS's on 64-bit hardware.
4. On 64-bit platforms where WebSphere MQ provides both a 32-bit and a 64-bit product, there is NO migration path from V6 32-bit Queue Managers to V6 64-bit Queue Managers. You are strongly advised to install WebSphere MQ 64-bit products on 64-bit platforms as there is a migration path from V5 32-bit products to V6 64-bit products.
5. The 'MQ Explorer' is not supported on this platform.
6. WebSphere MQ V6.0.2.0 or later is required.
7. For details of the Support Statement for JCA (on WebSphere MQ V6.0.2.1 or later only) please see here.
8. Defect support is available for virtualisation environments where they relate to releases of this platform already supported by WebSphere MQ, regardless of whether Linux for zSeries is running natively in a LPAR or within a z/VM, or whether IFLs are used. Unless stated elsewhere in the system requirements, WebSphere MQ has not been specifically tested in virtualisation environments. WebSphere MQ Support is therefore unable to assist in issues related to configuration and setup, or issues that are directly related to the virtualisation environment itself.
9. On Linux platforms, if you need to use SSL in a C++ MQ application then you must link the application against the libstdc++.so.5 runtime library. This is because the version of the GSkit SSL libraries supplied with MQ depends on libstdc++.so.5 and this GSkit version is not compatible with other C++ runtime library versions. MQ C++ applications built against the GCC 3.2 or 3.3 C++ runtime libraries comply with this restriction and will be able to use SSL.
10. WebSphere MQ V6.0.2.5 or later is required.
11. SELinux must be disabled.
12. WebSphere MQ V6.0.2.5 or later is required.
13. WebSphere MQ V6.0.2.6 or later is required.
14. WebSphere MQ V6.0.2.8 or later is required.
