ORAchk & EXAchk have been completely rewritten, with a focus on performance and extensibility.

Internal testing results show this version runs up to 3 X faster than Performance is particularly improved on lower resourced environments.


Option to Only Run Checks That Previously Failed


New option allows ORAchk/EXAchk to only run checks that failed previously:


    Generate a health check report

Use the failed checks option by passing in the html report, zip or directory

Windows Support Without Requiring Cygwin


As ORAchk has now been rewritten in Python, it no longer has the need for Cygwin on Windows.

New /etc/sudoers entry:

oracle ALL=(root) NOPASSWD:/home/oracle/


The location of this script can be changed by setting the environment variable RAT_ROOT_SH_DIR

export RAT_ROOT_SH_DIR=/some/other/location
