Relinking OracleOnly needed if :

An OS upgrade has occurred.

A change has been made to the OS system libraries. This can occur during the application of an OS patch.

A new install failed during the relinking phase.

Individual Oracle executables core dump during initial startup.

An individual Oracle patch has been applied (However, explicit relink instructions are usually either included in the README or integrated into the patch install script)
