This video demonstrates how Instana on z/OS provides full end-to-end observability, benefiting both IT operators and mainframe experts to rapidly isolate and diagnose a problem without friction. Specifically, this demo use case features the scenario where mainframe services are accessed by two different distributed applications, including a microservice application that enters CICS Transaction Server for z/OS and Db2 through HTTP or SOAP and a Java application that uses JDBC to access Db2.
