The db2prereqcheck utility could not find the library file libnuma.so.1. on ubi7/ubi:latest docker image

Question

i have a problem to install numactl-libs (or libnuma.so.1) on a ubi7/ubi:latest Docker image to run the db2 installation.

I have built a Docker image for db2 and wanted to test whether the DB2 installation runs successfully. However, I get the following error message:

Requirement not matched for DB2 database "Server" . Version: "11.1.4.6".
Summary of prerequisites that are not met on the current system:
DBT3609E The db2prereqcheck utility could not find the library file libnuma.so.1.

The image has ubi7/ubi:latest as base image and the following libraries are also installed as follows:

RUN yum install -y libaio numactl-libs libpam.so.0 binutils gcc gcc-c++ ksh numactl && yum clean all

All libraries are successfully installed except numactl-libs (or libnuma.so.1?).

Note: a manual installation of numactl-libs worked without problems and thus the DB2 installation was successful:

ADD http://mirror.centos.org/centos/7/os/x86_64/Packages/numactl-libs-2.0.12-5.el7.x86_64.rpm numactl.rpm
RUN rpm -i numactl.rpm

However, I would like the installation of numactl-libs to be done automatically with e.g. the command yum install -y numactl-libs or another equivalent command.
Unfortunately, an attempt with the command yum install -y libnuma.so.1 or yum install -y libnuma.so.* did not change anything and the same error message was displayed.

Can you please help me? I would be very grateful

Note: in my case a 64-bit version is used.

Update:

• Unfortunately even trying to install libnuma-dev and libnuma1 has not changed anything and the error message is still the same .
• The output of yum provides libnuma.so.1 is:

Loaded plugins: ovl, product-id, search-disabled-repos,
subscription-manager This system is not registered with an
entitlement server. You can use subscription-manager to register.
No matches found

• It seems that the problem is that numactl-libs cannot be installed: The output of yum install numactl-libs is:

Loaded plugins: ovl, product-id, search-disabled-repos, subscription-manager. This system is not registered with an entitlement server. You can use subscription-manager to register. No package numactl-libs available.

Answer 1

Solution:

The problem was fixed and numactl-libs could finally be installed: After I created a Red Hat user account and registered and subscribed to a system for the Red Hat Customer Portal with Red Hat Subscription Manager, numactl-libs installed without any problems.

To register and subscribe to a system for the Red Hat Customer Portal with Red Hat Subscription Manager. See the following link: (https://access.redhat.com/solutions/253273)

I added the following line in my Dockerfile before the command yum install numactl-libs: subscription-manager register --username=[USER_NAME] --password=[PASSWORD] --auto-attach

After these steps the DB2 installation ran without problems.

Thank you very much for your tips and help!
