On Linux 7, while running TFA or ORAchk, it might fail with below errors:

[oracle@racnode1 orachk]$ which perl
/bin/perl

[oracle@racnode1 orachk]$ ./orachk -u -o pre

SOLUTION

Use Oracle Perl instead of Linux 7 Perl.

$ export PATH=/u01/app/oracle/product/12.1.0/dbhome_1/perl/bin:$PATH

$ which perl
/u01/app/oracle/product/12.1.0/dbhome_1/perl/bin/perl
