Prerequisite Checker, DB2 agent and RedHat Santiago 6.7

The most recent versions of ITM agents bundles includes the options to perform an automatic verification of the needed prerequisites before proceeding with the installation.
This is done running the tool called Prerequisite Checker (PRS).
It leverages on a set of configuration files where the expected agent prerequisites are listed; the tool executes data collection to compare the
obtained information with the prerequisites listed in the configuration files, and if something does not match, it returns a FAIL status for the specific property.
Among the many prerequisite properties, there is of course the "supported Operating Systems".
Recently I faced a problem while installing the DB2 Agent (UD agent) v7.1.Prerequisite Checker was returning a failure concerning operating system, despite RHEL 6.7 was known to be
a supported platform.
This is not a very common scenario, but I believe it worth to talk about it in case someone else experienced the same issue.
This is the output returned by the Prerequisite Checker about OS verification:
Property Result Foun
As you can see, the OS Version verification returned a FAIL result.
This occurred because it was not able to correctly identify the operating system, that is actually a RHEL 6.7, and instead compared the list of supported OS with the string "LSB_VERSION".
Why did it find this value ?
This behaviour can happen if you run a LSB (Linux Standard Base) version of Linux.
This does not mean that the agent is not supported in this platform.
Simply, you can ignore the FAIL returned by the Prerequisite Checker and continue with the agent installation (unless you found other errors in the PRS output).
The PRS shipped with KUD agent V7.1 is a much older release and it reflects the SDK level used by the agent.
For the moment, just ignore the OS Version verification failure in the PRS output if you are running a RHEL 6.7 LSB version and proceed with agent installation if the verification for all
the other prerequisite returned PASS status.
Have a nice day
