Oracle Database Discussions

dear Gurus,

I've created a Standby, and Configured the Dataguard no issues.

I've start a swtchover into Site 2
After half an Hour without responding I cancle the operation.
Now I'm facing this Situation, My Standby Site still Ok but my Prod Database shows ORA-01666: controlfile is for a standby database
What shall i do?
When I check the Config in the Dataguard Broker everything seems ok for SITE 2

DGMGRL> show site verbose 'CFMP_SITE2';
Site
Name: 'CFMP_SITE2'
Hostname: 'srvsdmwebp02'
Instance name: 'CFMP'
Service Name: 'CFMP_SITE2'

Number Generic Processes: '0'

PFILE: ''
Number of resources: 1
Resources:

Current status for "CFMP_SITE2":

DGMGRL>

But in Site 1 it's different
DGMGRL>
DGMGRL> show site verbose 'CFMP_SITE1';

Resources:

How shall I proceed ?
