Macro Hunter

Identifies and measures activity and interactions between your mainframe and various hybrid integrations, RPA bots, macros, or scripts.

Identify Inefficiencies

How core processes integrate with the mainframe can slow down business workflow and act as a barrier to growth. If you rely on screen scraping or terminal emulation to integrate your RPA bots, scripts or desktop macros with the mainframe, you may experience performance and availability issues. The HostBridge Macro Hunter identifies where potential bottlenecks are and prescribes strategies to resolve them before they cripple your key business processes.

HostBridge Macro Hunter:

  • Provides end-to-end visibility of hybrid, RPA, or macro interaction performance with screen-based mainframe applications.
  • Reveals the precise details of interaction patterns to identify where inefficiencies exist.
  • Creates awareness of the impact these inefficiencies have on performance, cost, and the user or customer experience.
  • Prioritizes problematic integrations for optimization or remediation. 


If your core business processes running on IBM Z CICS participate in hybrid applications, interact with RPA bots, or have screens scraped by macros, HostBridge Macro Hunter provides critical insights. These insights lead to better performance, greater efficiency, lower overall CPU consumption, and a better user/customer experience.

Use Case

A global payments processing company saw its credit card authorization process balloon to over two hours to complete. Many customers were unwilling to wait, resulting in lost business. The HostBridge team identified screen scraping macros running off the mainframe as the source of process inefficiency. Replacing macro interaction with CICS APIs eliminated multiple requests and the associated network latency. The CICS APIs run on the mainframe where they exploit features of CICS and the IBM Z architecture. The card authorization business process is now invoked via a single HTTP request  that orchestrates the mainframe transaction sequence that returns a single response to the requesting application. This all occurs much faster, without screen scraping, and within the existing security infrastructure.
