Checking the operating environment

 

Before installing WebSphere MQ V6.0, check that your system meets the hardware and software requirements set out in this topic.

WebSphere MQ does not support host names that contain spaces. If you install WebSphere MQ on a computer with a host name that contains spaces, you will be unable to create any queue managers.

• TCP/IP (provided by the base operating system).

• IBM Communications Server for Linux, V6.2 (SNA).

• IBM Communications Server for Linux on zSeries, V6.2 (SNA).

 

Operating System, WebSphere MQ for Linux, Version 6.0 (zSeries s390x platform)

WebSphere MQ for Linux, V6.0 (zSeries s390x platform) has been tested with the following distributions:

• Red Hat Enterprise Linux V4.0

• SuSE Linux Enterprise Server (SLES) V9

 

Connectivity Requirements

Check that the system has 64-bit compatible communications hardware that supports:

• TCP/IP (provided by the base operating system).

• IBM Communications Server for Linux, V6.2 (SNA).

 

Threading Models

The support for threads on Linux is provided by the pthreads library.

• Most distributions based upon the 2.4 series kernels, such as those based upon UnitedLinux 1.0, include the LinuxThreads pthreads library. This threading library differs from most others in that the 'getpid()' function returns a different value for each thread in a process and is identified as a separate process in the output of the 'ps' command.

• Most distributions based upon the 2.6 series kernels, such as those based upon UnitedLinux 2.0, include the Native Posix Threading Library (NPTL). NPTL was written as the replacement to LinuxThreads and relies on updates made to recent kernels to overcome some of the shortfalls of LinuxThreads. Notably, threads within a process return the same pid from calls to 'getpid()' and closer compliance to the POSIX Threads specification.

Both of these threading models are supported for use with the WebSphere MQ Queue Manager and applications which connect to WebSphere MQ.

Other threading libraries exist as replacements for these threading libraries, however, none of these replacements are supported for use with the WebSphere MQ Queue Manager or applications which connect to WebSphere MQ.

 

Connectivity Requirements

The network protocols supported by WebSphere MQ for Linux, V6.0 (x86 platform) and WebSphere MQ for Linux, V6.0 (zSeries platform) are TCP/IP and LU6.2 . TCP/IP is part of the WebSphere MQ for Linux, V6.0 (x86 platform) and WebSphere MQ for Linux, V6.0 (zSeries platform) operating systems. If you want to use the SNA LU6.2 support on WebSphere MQ for Linux, V6.0 (x86 platform) or WebSphere MQ for Linux, V6.0 (zSeries platform) you need the IBM Communications Server for Linux Version 6.2. The Communications Server is available as a PRPQ product from IBM. For more details, see: http://www.ibm.com/software/network/commserver/about.

The network protocol supported by WebSphere MQ for Linux, V6.0 (POWER platform) is TCP/IP. We can use any communications hardware supporting TCP/IP.
