SQLPlus could not be started

After AIX OS Upgrade, I encountered the following via starting up a SQLPLUS session:

oracle>/appl/oracle/product/9.2.0/bin> sqlplus /"as sysdba"
exec(): 0509-036 Cannot load program sqlplus because of the following errors:

Cause:

The Anonymous I/O driver was not linked by the Unix Administrator

Solution:

Relink Anonymous I/O driver and Reboot the server.
