required for MySQL replication to keep the Cisco 
Prime Network Registrar IPAM database updated from 
the Production Executive.  This can be accomplished 
using the DemoteExec.sh script provided in the 
$INCHOME/etc/support directory of the Cisco Prime 
Network Registrar IPAM installation: 
> $INCHOME/etc/support/DemoteExec.sh 
3.2.1.4  Updated copies of default.incontrol and incstatus 
 
As indicated previously, you must keep current copies 
of the default.incontrol and incstatus files from the 
Production Executive on the DR Executive.  Both files 
are located in $INCHOME/etc.  When copied to the 
DR Executive, they must be named 
default.incontrol.primary and incstatus.primary, 
respectively, and located in $INCHOME/etc. 
 
3.2.2  Disaster Recovery Procedure 
This section describes the procedure necessary to initiate a DR 
event or exercise under this scenario. 
3.2.2.1  Demote the Production Executive database, if possible 
If this is a planned DR exercise where the Production 
Executive will eventually resume its role as the Active 
Master database, then demoting the Production 
Executive database at the start is preferable.  To do 
this, execute the demote_master.sh script located in the 
$INCHOME/etc/support directory on the Production 
Executive: 
> $INCHOME/etc/support/demote_master.sh
 
 
This script will ensure that no unintended writes will occur 
on the Production Executive database and will help 
with a smooth transition back to “normal” operation.  
In addition it will generate the appropriate parameters 
to call the promote_master.sh script on the DR 
Executive. 
3.2.2.2  Promote the database on the DR Executive to Active Master 
At this point, we will assume that either the Production 
Executive is down, or that the Production Executive 
database has been demoted to a Passive Master.  
Therefore, we need to promote the database on the DR 
Executive to an Active Master.  The process varies 
slightly dependent upon if the Production Executive 
was demoted.  If it was demoted we will use the 
parameters generated from the demote_master.sh
