Autosys 12.x fails with below error during the Database Validation steps:
[CAUAJM_E_119009] Unable to determine the bitness of the library. Or,
"libclntsh.so" is not a 64-bit client shared library.
PRESS <ENTER> TO ACCEPT THE FOLLOWING (OK):
Oracle 64 bit client is already installed, but is missing the exact library (libclntsh.so). The installer is looking for libclntsh.so file
Create a soft link libclntsh.so pointing to libcltnsh.so.12.1 (or libcltnsh.so.19.1 for 19c)) and retry the installer.
