While creating the domain using domain utility using cmd utility on Red Hat Linux 8.x and higher, or Red Hat equivalent linux distribution , Utility fails with below error:
=====================
[ec2-user@ip-172-31-19-240 bin]$ ./domainutilitycmd -cmdFile /home/ec2-user/BWProducts/CreateDomain.xml
./domainutilitycmd: error while loading shared libraries: libnsl.so.1: cannot open shared object file: No such file or directory
=====================
The same error may happen running other components like AppManage, Domain Utility, desginer, traUpgradeManager etc.

Cause:
Shared library "libnsl.so.1" is required by TRA wrapper, but is not available on the system. 

Run command below to install the libnsl package explicitly:
             $sudo dnf install libnsl*

After the installation, you should see all libraries are available like below if you run command "ldd domainutilitycmd":
$ldd domainutilitycmd
        linux-vdso.so.1 (0x00007fff1478a000)
        libnsl.so.1 => /lib64/libnsl.so.1 (0x00007ff6861b5000)
        libdl.so.2 => /lib64/libdl.so.2 (0x00007ff685fb1000)
        libpthread.so.0 => /lib64/libpthread.so.0 (0x00007ff685d91000)
        libstdc++.so.6 => /lib64/libstdc++.so.6 (0x00007ff6859fc000)
        libm.so.6 => /lib64/libm.so.6 (0x00007ff68567a000)
        libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007ff685462000)
        libc.so.6 => /lib64/libc.so.6 (0x00007ff68508c000)
        /lib64/ld-linux-x86-64.so.2 (0x00007ff6863ce000)
