When installing Control-M/Enterprise Manager 9.0.21 the following error is received when loading shared libraries: "libnsl1.so.1: cannot open shared object file: No such file or directory" when libnsl.so.1 and libnsl.so.2 are already installed.

From the installation log something like below can be found:

Create a soft link between libnsl.so.2 and libnsl.so.1 running command:

ln -s /usr/lib64/libnsl.so.2 /usr/lib64/libnsl.so.1

Run again the installation
