Keep in mind the following when setting up global reporting:
• Multiple Global Reporter Servers - Global reporting can be set up at multiple sites. Your
associates in London and Tokyo can also set up global reporting at their site so they obtain data
gathered by management server in New York City.
• Multiple Sites - If you do have multiple Global Reporter servers, each Global Reporter server
must contact each site that has the data the Global Reporter server wants to include in global
reports. For example, assume you set up a Global Reporter server in Tokyo that collects data
from a site in London. You also have another Global Reporter server in New York City. The
Global Reporter server in New York City must contact the Global Reporter server in Tokyo and
the site in London to obtain data from Tokyo and London. If the Global Reporter server in New
York City contacts just the Global Reporter server in Tokyo, it does not obtain data from the site
in London.
• Data Gathering - The Global Reporter server gathers data from sites as scheduled or when the
Refresh Now button on the Global Reporter tab is clicked. The management server pulls data
from a site's local materialized views, which are snapshots of relevant data from the site's local
database. During a refresh, the Global Reporter server contacts each site and attempts to pull
data from its materialized views. If a site's local view is refreshing, the Global Reporter server
skips pulling the data from that view and proceeds pulling data from the remaining views. The
Global Reporter server then attempts to pull data from the skipped views.
• Firewalls - If a site is behind a firewall, the port for the Oracle TNS listener must be open. For
example, if the site uses port 1521 for its TNS listener, this port must be open on the firewall.
• Contact Status - The Contact Status column on the Global Reporter tab only verifies if the
management server was able to contact the site. It does not specify if the refresh was successful.
For example, if the Global Reporter server is able to contact the site, but the refresh fails. The
Contact Status column still reports “SUCCESS” because the site was able to be contacted. If you
have trouble contacting the site, try pinging it to verify the network connection is working. If ping
works, verify the management server on the site is running.
• Unable to Contact Site - If the management server is unable to contact one of the sites in the
Global Reporting list, the refresh process will not start. You can verify if a site can still be
contacted by clicking the Test button for the site. You may want to try pinging the machine and
