UPDATE To USER$.SPARE6 Performs Poorly (2-Second Execution Time) and Consumes CPU When TDE and FIPS enabled (Doc ID 2280676.1)

Last updated on SEPTEMBER 14, 2021

Applies to:

Advanced Networking Option - Version 12.1.0.2 and later
Information in this document applies to any platform.

The following statement performs poorly (taking 2+ seconds to complete) and consumes CPU:

update user$ set spare6=DECODE(to_char(:2, 'YYYY-MM-DD'), '0000-00-00', to_date(NULL), :2) where user#=:1

The behavior is seen specifically when Transparent Data Encryption (TDE) and FIPS mode are both in use.

The problem occurs after upgrading to 12.1.0.2.
