Error: "ORA-02291: integrity constraint violated - parent key not found" when Predictive Diagnost (4327797)

When Predictive Diagnostic feature is enabled, the following errors are  found in Oracle  ALERT LOG

ORA-12012: error on auto execute of job <job_id>
ORA-02291: integrity constraint (QUEST.SYS_C<auto_gen_id>) violated - parent key not found
ORA-06512: at "QUEST.QUEST_PPCM_SNAPSHOT_PKG", line 903
ORA-06512: at "QUEST.QUEST_PPCM_SNAPSHOT_PKG", line 1032
ORA-06512: at "QUEST.QUEST_PPCM_SNAPSHOT_PKG", line 1040

Product defect.

WORKAROUND 1:

Disable the Oracle job.

1.  Go to File | Oracle User Wizard. Follow through the wizard until the "Setting Predictive Diagnostics" screen is reached.
2. Set both intervals (SQL Performance Collection and Bottleneck Collection interval) to zero. A warning is displayed, and click Next up to the end of the wizard.  Refer to attached screenshot1.  

Note : This will prevent the error in the alert.log. The predictive diagnostic feature will be disabled, and   the Spotlight console shows an alarm  regarding non-running job in the predictive diagnostics component screen.

WORKAROUND 2:

1. Drop the Spotlight on Oracle user.
2. Go to File | Oracle User Wizard to create a new user
3. Answer "No" to 'Do you want Predictive Diagnostics?', which will disable the feature.

STATUS:

Waiting for fix in a future release of Spotlight on Oracle.

To confirm that this is due to Predictive Diagnostic:

Run this query:
select * from user_jobs where job=<job_id>;

The result should indicate the following:

BEGIN /*Quest SOO PPCM job */   quest_ppcm_snapshot_pkg.take_snapshot; END;
