continue. If a requirement is not met, the Installer corrects the problem if it can; otherwise it
displays instructions so you can manually correct the problem, then it exits. As well as displaying
the error on the screen, each component logs the error to its respective log le.
Note: System IPCC component roles are somewhat different from ICM/IPCC component roles.
ICM/IPCC Distributor AWs with WebView and HDS have the role of Administration & WebView
Reporting in System IPCC. An IPCC System PG plus CTI Server and CTI OS Server in System
IPCC has the role of Agent/IVR Controller. The Outbound Option MR PG and Dialer have the
role of Outbound Controller. In System IPCC, the Logger and CallRouter are always co-located
on the same Central Controller machine.
Installations are usually performed during off-peak hours. Keep in mind that you might require
more than one maintenance window. Normally, an initial maintenance window is established
to get the ICM Central Controller and critical (key) AWs upgraded rst. The remaining AWs
and PGs are then scheduled as early as maintenance windows allow.
Note:
Ensure you have run the Release 7.2(1) Installer on all your remaining AWs before bringing
them online.
The Peripheral Gateways do not necessarily have to be upgraded during the same maintenance
window as the Central Controllers. For additional information, refer to the Cisco ICM/IPCC
Enterprise & Hosted Editions Hardware and System Software Specications (Bill of
Materials) (http://www.cisco.com/en/US/products/sw/custcosw/ps1001/
products_user_guide_list.html).
The Installer also performs uninstallation. You can perform either a Permanent uninstallation
or a Temporary uninstallation.
Note: The option to perform a temporary uninstallation is available only on components having
a database (the Loggers, HDSs, and Distributor AWs). Components that do not have a database
can only be permanently uninstalled.
Permanent Uninstallation
Selecting a Permanent uninstallation performs both a rollback of the database schema to the
previous release schema and uninstalls the Release 7.2(1) application; deleting all conguration
data specic to Release 7.2(1). New or changed conguration data that is unrelated to Release
7.2(1) features (for example, new agents and skill groups) is, however, retained.
A permanent uninstallation performs the following tasks:
Performs the uninstallation of the Release 7.2(1) application.
Reverts the database to the previous release of ICM/IPCC schema version.
Logs the results, then exits.
