Question

We are facing issue while installing Websphere MQClient v9.0.0.1 on linux machine.at the time of rpm packages installation we are getting below error.
Note: And it is Multi-installation setup,we have a MQClient version 8.0.0.4 in different file system which is Installation1 file system is /Informatica/app/MQClient.
Installed packages on server.
MQSeriesMan-8.0.0-4.x86_64

We could see the libmqmr_r.so file in below location
/infaicc/app/MQClient/lib/libmqmr_r.so
We have set the environment variableby using below command
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/infaicc/app/MQClient/lib64
but still we are facing same error.

Please let us know is it mandatory to run this crtmqpkg suffix in multiple installation scenario, if yes kindly confirm from which location I need to run this ( means from installation1 ) command.
Our existing setup is working fine without any issue. If we run crtmqpkg suffix command is there any impact on my existing version.
Before installation should we stop the all existing MQ process?
#Roger/Josh: Thanks for update,we are getting below error while executing ./crtmqpkg 2. kindly help on this issue.
[root#xxxx_xxx_xx_ mqclient]# ./crtmqpkg 1
ERROR: Unable to execute "/usr/bin/rpmbuild" - required for packaging.
Check that you have the "rpm-build" package installed on your system,
or which ever package provides "rpmbuild" on your Linux distribution.
#Josh: we have installed the rpm-build packages and run the ./crtmqpkg 2 command it got succeed but while installing websphere MQ rpm packages getting below error.We followed the given IBM tech-notes still facing error.

Answer 1

Did you follow the MQ instructions here or here because I don't see any mention of creating the install package. Also, you need to set your installation but I don't see anything about it either.

Answer 2

As Roger pointed out the following IBM MQ Knowledge Center page provided details: IBM MQ 9.0.x>IBM MQ>Installing and uninstalling>Installing and uninstalling IBM MQ on Linux>Installing IBM MQ on Linux using rpm>Installing IBM MQ server on Linux
First this page answers your first question:
Note
The crtmqpkg command is required only if this is not the first
installation of IBM MQ on the system. If you have earlier versions of
IBM MQ installed on your system, then installing the latest version
works correctly if you install it in a different location.
Given that it appears you already have MQ v8.0.0.4 installed you will need to perform the required steps to create a MQ v9.0.0.7 set of rpms with a new suffix.
The reason this is required is because you can not install two rpms with the same base package name. By creating a new RPM with a suffix is giving the rpm a different base name.
Actually running the crtmqpkg command will not cause any issues with your existing installation since it is just creating new rpm files on the file system. When you install it as long as you specify a different installation location it will not cause any problem for your existing installation either.
Roger provided the second link to the IBM MQ Knowledge Center page that provides details specific to the MQ client packages: IBM MQ 9.0.x>IBM MQ>Installing and uninstalling>Installing and uninstalling IBM MQ on Linux>Installing IBM MQ on Linux using rpm>Installing an IBM MQ client on Linux
If you have multiple installations on this system, you must run crtmqpkg to create a unique set of packages to install on the system:
a. Enter the following command:
./crtmqpkg suffix
where suffix is a name of your choosing, that will uniquely identify the installation packages on the system. suffix is not the
same as an installation name, although the names can be identical.
suffix is limited to 16 characters in the ranges A-Z, a-z, and 0-9.
b. Set your current directory to the location specified when the
crtmqpkg command completes. This directory is a sub-directory of /var/tmp/mq_rpms, in which the unique set of packages is created. The
packages have the suffix value contained within the filename.
Because the installation of the new package is not going into the same location there is No requirement to stop existing IBM MQ processes.
