Step 9:
Manage Failover
(if applicable)
Failover is a GlobalScan Ver. 2.0 function whereby MFDs can communicate with an alternate
GlobalScan Server in the event the primary GlobalScan Server goes down. Incorporating
Failover ensures maximum uptime of the GlobalScan system. Failover is transparent to the
user, though once implemented he/she may be required to log in again. Once the primary
server is back up, and after the current user session on the secondary server is completed,
GlobalScan operation resumes on the primary server.
The prerequisites for successful GlobalScan Failover operation include the following:
•
One permanent license has been activated
on the primary server, i.e., the server is
activated with an “03” CD Activation Key, e.g., JBVTXUI030000085.
•
One permanent license has been activated on the secondary server, i.e., the server is
activated with an “04” Activation Key, e.g., JBXDXUI040000045.
Note
: Servers configured with “04” (secondary) Activation Key cannot update data, with a few
exceptions (explained later in this section). If needed, a secondary server can be promoted to primary
server status by deactivating the “04” Activation Key and reactivating with the “03” Activation Key.
•
The primary and secondary GlobalScan Servers must be configured exactly the same,
including all Plug-ins and Plug-in client software, and most importantly, each server
must have the exact same date and time zone settings, otherwise synchronization will
not be completed correctly. The secondary GlobalScan Server will automatically
update itself if the primary server’s database configuration is modified, including Plug-in
settings.
Note
: All GlobalScan Ver. 2.0 and Ver. 1.5 Plug-ins are supported by the primary and
secondary servers.
•
GloblalScan Ver. 2.0 must be installed with the latest OCR Plug -in and engine (OCR
file conversion program). The OCR Plug-in must be installed separately for the primary
and secondary server. The OCR engine should be installed on both the primary and
secondary server. If installing the OCR engine on one server, it must be on the
secondary server.
Failover occurs when the
MFD cannot submit a job
to the primary Global-
Scan Server. Four
possible causes include:
1.
Network or other
physical connection
failure.
2.
Web service is down.
3.
Web service is up, but
GlobalScan Data
Service is down.
4.
Web service and
GlobalScan Data
Service are up, but
primary server is in
“maintenance mode.”
