Issue with links during OAS server installation

Tomasz Antosz

Hello,

I came across an issue with some links during installation process.

The overall installation has been completed successfully (I hope).

Would you be able to tell whether those issues can cause any other problems during next installation (RCU) and configuration phase?

Thank you.

Agree, to be more specific, you are likely missing an FMw Infrastructure requirement: libnsl.x86_64

Hi @User_UZC1Y

Thank you for visiting and posting your question in Oracle Analytics Community.

Please make sure you have followed below document in preparing your server prior to installing and configuring OAS.

https://docs.oracle.com/en/middleware/bi/analytics-server/install-config-oas/preparing-install-and-configure-product.html#GUID-F14257C7-ADD2-42C6-9C50-0CEEB3821905

As this is a fresh install I would recommend to wipe out everything and start from scratch by verifying system requirements.

Thanks

Thank you both for your help, I've fix the issue by installing libnsl.x86_64 :)

But I'm wonder why this lib was not flagged as missing during OS package check?

I've found another package with similar name (libnsl2.x86_64).

Could this cause the problem?

Hi @User_UZC1Y
It would be great if you update your Display Name in your profile, so we know with whom we are communicating with in the community ;-)

There are a couple of bugs logged for the FMw installer, but it seems like it was resolved as a documentation issue, instead of a code defect. The packages are listed in the documentation attached here.

https://docs.oracle.com/en/middleware/fusion-middleware/12.2.1.4/sysrs/system-requirements-and-specifications.html#GUID-37C51062-3732-4A4B-8E0E-003D9DFC8C26

I've found another package with similar name (libnsl2.x86_64).
Could this cause the problem?

No, additional packages are fine, and not the root cause. The root cause was the missing package.

Glad you were able to proceed with the installation, we hope you enjoy the product features.

Hi, sorry, I didn't check my display name when creating the first topic ;)

I've already change it :)

The package libnsl is listed as requirement for years already.

But I'm wonder why this lib was not flagged as missing during OS package check?

To be fair the installer does a bare minimum check of only a very limited list of packages compared to the requirements documented (in my memory from the time I had to adapt the checks to match newer versions, it was checking only 5-8 packages at best, while the list of the documentation is longer).

It's your duty to always make sure your OS has all the listed packaged and the right OS settings, because the installer does only some generic tests on some key pieces, but doesn't check all the requirements. It has always been like that…

The day they do release the installer as a RPM instead of JAR the checks will be strict with the dependencies, but I believe it will never happen (mostly because a RPM only works on some installs, not all).

Always make sure to go through all the requirements documented yourself before to install FMW, or you could have surprises at any point in time with something not working, because it can't find a library it does depends on… (and this could also happen after using the tool for weeks or months, just because something you will do will need a missing package: good luck in debugging that if it does happen).
