Why do I see the PostgreSQL error log "FATAL:
terminating connection due to administrator command"
in the Windows event log?
Possible Cause: This error is caused by Power Center server shutdown. Normally, the Power Center
database service (Dell OpenManage Power Center Database Server service) stops after other Power
Center services; however, if the Power Center server has been shut down quickly, the Power Center
database service is forced to stop when other Power Center services are not yet stopped. In this case, the
database connection sessions that cannot be closed by other Power Center services is closed by the
Power Center database service, and this error is generated. Since such an error is caused by Windows
when it shuts down the services quickly, Power Center protects the important data through transaction;
therefore, this kind of error does not impact Power Center.
Resolution: No action is required.
Why I can’t open power center login page when I access
it through Firefox 31?
Possible Cause: During the installation of power center, a self-signed certificate is created for power
center. If end user has replaced this self-signed certificate with a certificate signed by a well-known
CA(Firefox recognize this CA), then you do not encounter this issue. Mozilla has improved its certificate
verification process. For more information, visit www.wiki.mozilla.org/SecurityEngineering/
Certificate_Verification. As a consequence of this improvement, when end users access power center
through Firefox 31, they may get an “sec_error_ca_cert_invalid” error.
Resolution: Following are the solutions recommended to handle this issue:
1. Use a different web browser
2. Replace power center’s self signed certificate with a well-known CA signed certificate.
3. Search Mozilla Firefox official documents for solution.
If the above solutions do not work, you can try the following procedure.
1. Delete all Firefox 31 remembered self-signed certificates.
2. Delete all Firefox 31 remembered histories.
3. Restart Firefox31.
4. Try open power center again.
