Installing MQIPT

IBM® MQ Internet Pass-Thru (MQIPT) is available on AIX®, Linux®, and Windows. You can install MQIPT wherever you want on your computer, and can have several installations on the same system.

About this task

Each installation can be used and maintained separately. For example, you can have different fix pack levels of MQIPT installed in different locations if you choose.

The installation location is not fixed. MQIPT can be installed anywhere on the system. It is not necessary to set the system PATH or CLASSPATH environment variables to refer to MQIPT.

The MQIPT commands can be invoked from any location and MQIPT automatically detects its own location. You might choose to add the MQIPT bin directory to the PATH environment variable for convenience, but it is not mandatory to do so.

You can also install MQIPT alongside previous versions of MQIPT. You can have only one installation of MQIPT version 2.0 on the same system because of the installation method used by version 2.0.

If you run MQIPT as a system service, you can install only one such service on each system. You cannot install more than one MQIPT service on the same system, either from the same MQIPT installation or from different installations. Also, only the installation of MQIPT that installed the service can be used to remove it. For example, if you have two MQIPT installations, one in C:\mqipt1 and one in C:\mqipt2, and you run the command C:\mqipt1\bin\mqiptService -install C:\mqipt1, then only the mqiptService command from the C:\mqipt1 installation can subsequently be used to remove the service. Attempting to remove the service using a different installation causes error MQCPE083.

Procedure

To install MQIPT, complete the following steps:

Download the MQIPT package for the platform you require from IBM Fix Central for IBM MQ. The MQIPT for IBM MQ 9.1.x packages are available under the following names:

Platform	Archive file
AIX	9.1.x.0-IBM-MQIPT-AIXPPC64.tar.Z
Linux x86 (64 bit)	9.1.x.0-IBM-MQIPT-LinuxX64.tar.gz
Linux zSeries	9.1.x.0-IBM-MQIPT-LinuxS390X.tar.gz
Linux PPC (Little Endian)	9.1.x.0-IBM-MQIPT-LinuxPPC64LE.tar.gz
Windows (64 bit)	9.1.x.0-IBM-MQIPT-Win64.zip

Choose the location where you want MQIPT to be installed.
When you unpack the MQIPT installation archive file, a directory called mqipt is created, and the installation files are all placed in this directory. If necessary, create a new directory where you want MQIPT to be installed.
For example, on a UNIX platform, you might use the following command:
```
mkdir /opt/mqipt/installation1
```
Unpack the installation archive file into the MQIPT directory by using an appropriate tool for your platform.

Note: The tar command on UNIX and Linux systems must be run as the root user when installing MQIPT. Failure to run the tar command as root is likely to result in "permission denied" errors.
For example, on a Linux platform, you might use the following commands, if the archive file was downloaded to the /tmp directory:
```
cd /opt/mqipt/installation1
su root
tar xzvf /tmp/9.1.4.0-IBM-MQIPT-LinuxX64.tar.gz
```
To increase security, set the file permissions for the installed files so that they are read-only:
- On UNIX or Linux systems, you can use the chmod command. For example:
```
chmod -R a-w /opt/mqipt/installation1/mqipt 
```
- On Windows platforms, right-click the installation directory and select Properties. You can change the file permissions on the Security tab.
If you subsequently receive error message MQCPE080 Unable to determine MQIPT installation directory, set the MQIPT_PATH environment variable to the absolute path of the MQIPT installation directory.

You do not normally have to set the PATH or CLASSPATH environment variables for MQIPT because the installation includes a Java runtime environment (JRE). However, under some circumstances (for example, if you use symbolic links), MQIPT commands are unable to determine the installation directory. This can be corrected by setting the MQIPT_PATH environment variable.
For example, if your installation directory is /opt/mqipt/installation1/mqipt, you might use the following commands:
```
MQIPT_PATH=/opt/mqipt/installation1/mqipt
export MQIPT_PATH
```
On Windows platforms, create MQIPT icons on the Start menu.
Run the following command from an administrator command prompt:
```
C:\mqipt_path\bin\mqiptIcons -install installation_name
```
where
- mqipt_path is the directory where MQIPT is installed.
- installation_name is a name that you choose to distinguish this installation from any other. The name is appended to the name of the MQIPT icons.
