IOver 14 years of data center experience where knowledge was gained by “walking the data center floor and visually inspecting cabling from the underneath of the floor tiles up to and into each connection into each rack” at AFTAC (Air Force Technical Applications Center) Patrick AFB, Florida. From that point, participated in datacenter modernization efforts at other centers, including learning how technology has evolved over time. System Administrator for Oracle Enterprise Management application. In charge of quarterly application patching, annual PKI certificate updates, Linux operating system “swap-outs”, coordination of changes and creating engineering documentation to record those activities. Also, engaged the FDA customers with Middleware functions that resulted in over 3000 ServiceNow incident tickets and 1000 change tickets resolved between 2014-2019. Middleware supports over 50 applications running on over 200 Windows and Linux Servers.• Proven understanding and use of operating systems Windows and Linux, BASH, Korn, Power Shell, ServiceNow ticketing system• Renewed PKI certificates starting with the CSR file on the Linux server. Then passing that information to the FDA PKI Certificate Authority. This was a SAN or “Subject Alternative Name” request. With the resulting .pem file, created user, intermediate and root certificates. Those were then installed into a certificate wallet on the OMS (OEM) servers by securing the OMS console, primary and secondary OMS servers, the then load balancer connection.• Quarterly patching for the OEM application started with patching not just the application but its components. OEM is a fusion middleware application PSU patches, OMS Server Side patches for plugins, WebLogic patches, and Management agent patches . The patching process could take up to 3 hours. Oracle modified the process in creating wrapper code where one patch included 12 to 24 sub patches.• Identified and tracked system vulnerability caused by out-of-date log4j and java versions
