Installing new servers during recovery After the database and/or load balancer is recovered: 1 On computers on which servers will be installed, make sure the time is synchronized with existing system components using an NTP server. 2 Perform server installations as normal, using the new database and/or load balancer. For more information, see "Installing servers" on page 34. 3 Install any third party services required by installed solutions on each new server. 4 Perform policy updates as necessary: • If the new database and load balancer are identified by the same IP address or addresses and fully qualified domain name or names as the failed database and/or load balancer, perform a policy update for any device groups that contain e-Task printers, making sure to clear the selection for Only update those devices which are Out of Policy. • If the backup database or load balancer is identified by a new IP address or fully qualified domain name, perform a policy update for all device groups, making sure to clear the selection for Only update those devices which are Out of Policy. 5 On the System tab in LMC, set the new servers online. 6 If new servers are identified by different addresses than the failed servers, the failed servers remain in the system and appear as non-communicating on the System Status page. To avoid impacting system performance, remove these servers using the System tab in LMC.

Likewise, if the setting is currently a fully qualified domain name, use the fully qualified domain name of the load balancer. Monitoring and maintaining the system 80

Installing new servers during recovery
After the database and/or load balancer is recovered:
1
On computers on which servers will be installed, make sure the time is synchronized with existing system
components using an NTP server.
2
Perform server installations as normal, using the new database and/or load balancer. For more information, see
“Installing servers” on page 34.
3
Install any third party services required by installed solutions on each new server.
4
Perform policy updates as necessary:
•
If the new database and load balancer are identified by the same IP address or addresses and fully qualified
domain name or names as the failed database and/or load balancer, perform a policy update for any device
groups that contain e-Task printers, making sure to clear the selection for
Only update those devices which
are Out of Policy
.
•
If the backup database or load balancer is identified by a new IP address or fully qualified domain name,
perform a policy update for all device groups, making sure to clear the selection for
Only update those
devices which are Out of Policy
.
5
On the System tab in LMC, set the new servers online.
6
If new servers are identified by different addresses than the failed servers, the failed servers remain in the system
and appear as non-communicating on the System Status page. To avoid impacting system performance, remove
these servers using the System tab in LMC.
Connecting existing servers during recovery
After the database and/or load balancer is recovered:
•
If the new database and load balancer are identified by the same IP address or addresses and fully qualified
domain name or names as the failed database and/or load balancer:
1
Make sure the time is synchronized among all system components using an NTP server.
2
Restart the Lexmark Solutions Application Server service from the Windows Services control panel on each
server.
3
Perform a policy update for any device groups that contain e-Task printers, making sure to clear the selection
for
Only update those devices which are Out of Policy
.
4
On the System tab in LMC, set the servers online.
•
If the new database or load balancer is identified by a new IP address or fully qualified domain name, perform
the following steps on each server:
1
Make sure the time is synchronized among all system components using an NTP server.
2
From the Services control panel, stop the Lexmark Solutions Application Server service.
3
In the file \Lexmark\Solutions\apps\wf-ldss\WEB-INF\classes\adaptor.properties where the LDD server is
installed, change each of the properties
adaptor.address
and
adaptor.canonicalhostname
to
the IP address or fully qualified domain name of the new load balancer.
Note:
If the setting is currently an IP address, use the IP address of the load balancer. Likewise, if the setting
is currently a fully qualified domain name, use the fully qualified domain name of the load balancer.
