4. High Load Monitor

When ALCS experiences a high work load, it is sometimes difficult to find out what the high load consists of.

The high load monitor is an update to ALCS monitor exit USRTIM2 to detect a high load situation and place information on the diagnostic file about each ECB in the system. An included offline program reads the diagnostic file and generates a simple report.

8. WTO Exit

This package contains an example MVS Write to Operator exit. In this example the exit is used to invoke a CLIST when an ALCS realtime sequential file is deallocated. This could be developed to manage the archiving of these files to ensure that space is available for subsequent files.

9. MQ Bridge Guide

This package contains an description of the ALCS MQ Bridge. The Bridge uses the MQ support in ALCS to provide connectivity to current ALCS applications from remote systems such as Web servers. It allows MQ messages received on request queues to be formatted and passed on to the applications as if they came from ordinary terminal devices.

10. ALCS Performance Monitor

The ALCS Performance Monitor satisfies User Group requirement ATC0262, which asked for the Performance Monitor developed by Jorge Widmar to be incorporated into ALCS. The documentation on the Performance monitor is in the standard manuals.

To assist those implementing the Performance Monitor for the first time we have collated the documentation from the standard manuals into a small document.

12. Websphere Application Server optimized local adapter

With WAS OLA support, you can create a web service to represent business logic implemented as a servlet or an Enterprise Java Bean (EJB). The application that gets control for the web service call can simply delegate to a connector call to ALCS. Using this approach, ALCS applications can readily be exposed externally as web services because all the necessary WAS external support and administration is in place.
