License acceptance on IBM MQ for Linux

Previously, you had to accept the license before installing the product on Linux® platforms. From IBM® MQ 9.2.0 you can choose to accept the license before or after product installation.

Why you would accept the license after installation

Accepting the IBM MQ license before you install the product causes the following issues for Linux users:

It stops you adding the IBM MQ RPM to a yum repository.
It does not fit well with working in the cloud, where the RPM is installed as part of building the image.
It does not fit well with unzippable packages, where no code is run before installation.

Accepting the license after installation lets you set up your own repository to install from.

Notes:

You still have to accept the license before you use the product.
You must have the correct license, or licenses, for the components you want to install. See license requirements.
If you have installed a trial license, follow the instructions for converting a trial license. See Converting a trial license on Linux.

Accepting the license before installing the product

For all IBM MQ versions, you can accept the license before installing the product on Linux platforms.

Follow the instructions for installing the server by preparing your system, and then following the appropriate instructions for your operating system:

rpm: See Installing the first IBM MQ installation on Linux using the rpm command.
yum: See Installing IBM MQ on Linux Red Hat using yum.
Ubuntu using Debian: See Installing IBM MQ on Linux Ubuntu using Debian.

Accepting the license after installing the product

From IBM MQ 9.2.0, you can install the license or licenses after installing the product on Linux platforms.

To install the license or licenses after installing the product, use the mqlicense command or the MQLICENSE environment variable. To view the license or licenses, use the dspmqlic command or the MQLICENSE environment variable.

Attention: Do not use the mqlicense.sh script from the installation media, because this script can only be used to accept the license before installation.
