2.2: APPX Replacement
APPX Replacement Other Information:
The APPX legacy environment is comprised of the departmental systems and the database of record that manages OPIC business
transactions. APPX data serves as a primary source of data for the OPIC Oracle Government Financials (OGF) core financial
system. APPX data is interfaced to OGF with a conversion operation called the daily interface. Given the maturity of the APPX
system in the software development lifecycle (SDLC) and the on-going implementation of the T24 application, there are no planned
expansions to the APPX system. APPX is at the end of the development and support lifecycle. As such, OPIC’s goal is to sustain
the usability of the system until all capability is replaced with new systems. OCIO has developed a high-level approach for
maintaining the viability of APPX by: • Mitigating the risks associated with the current APPX hardware and software platform,
• Planning for future hardware and software refresh until decommissioning, and • Defining the requirements for continued access
to the historical data, post-decommission. OCIO is currently planning to perform an initial and sequential upgrade to the
APPX hardware and software environments. The current lifecycle of APPX will require continued operation through 2011 and beyond
for historical data purposes. As a result, the initial upgrade will make APPX compliant with current technology standards.
The sequential upgrade will ensure future compatibility with OPIC systems. Over the longer term, OCIO plans to migrate the
backend processes for Loans to Oracle Loans, and investigate the development of a custom Oracle application for the Insurance
functions.
