Yes it is. For the time being, you can continue to reference the result showing to you in the CSA.
DE34600 - Health Report
SUMMARY
New health report reads the nls_date_format parameter at an inconsistent level to installation instructions and the CSA health check
STEPS TO REPRODUCE
1. Install CA PPM 15.2 on Oracle, make sure the database 'instance' parameter for nls_date_format is set correctly (e.g. 'alter system set nls_date_format='YYYY-MM-DD HH24:MI:SS scope=spfile' then restart Oracle)
2. Grant the PPM schema in Oracle the following permission: grant select on v_$parameter to <ppm_schema_name>
3. Login to the CSA and run the health check report
4. Observe that the date format receives a pass
5. Login to the PPM app as 'admin'
6. Navigate to Administration > Health Report
7. Navigate to the Database tab
8. Observe the Value and result for date format
Expected Results: Value should report 'YYYY-MM-DD HH24:MI:SS' and the result should be a pass (green diamond)
Actual Results: Value reports something like 'DD-MON-RR' and the result is a fail (red diamond)
Workaround: Use the result from the CSA.
