A next-generation artificial intelligence product that “thinks” when diagnosing problems.
If you are responsible for the production system and delivering CICS service to users, AUTOMON/CICS is a package you cannot do without. Many MVS sites achieve CICS availability of over 99%, but this is not good enough; someday CICS will crash. Application, system, and configuration changes occur frequently, often daily. Even with the best change control, this requires extensive system programmer coverage. Peak loads continue to increase to the point of system stress and extended response times.
Once you enable AUTOMON on your system, it will automatically identify CICS system problems, investigate the root cause of the problem, and dynamically take corrective actions to keep your CICS system available without interruption. Some of the features of AUTOMON include detection, investigation, and correction of: Loop conditions; System hangs; Storage violation conditions; SOS conditions, and many more. It will also automatically address additional performance issues by dynamically changing the MXT value (for maximum throughput based on resource availability), auto-detection of temporary storage shortages, pending MRO/ISC link capture, auto-analysis of VSAM and VTAM-related resource deadlock conditions, and prevent various types of CICS system aborts, which include but are not limited to U405, U409, U602, U615, etc.
AUTOMON/CICS reduces CICS system outages by detecting critical system problems early and dynamically correcting them. AUTOMON/CICS provides many services to assist in detecting and handling exceptional and abnormal conditions during CICS system execution. When AUTOMON discovers an abnormal condition, it checks extensively for storage corruption, loops, and various other exceptional conditions. After identifying the CICS system problem, it will diagnose the symptoms and take immediate corrective actions to prevent system crashes, increase system availability, and improve system performance. AUTOMON/CICS continuously captures significant activities and conditions from CICS, VTAM, VSAM, and other operating systems.
In normal processing, AUTOMON/CICS provides maximum efficiency by allowing all incoming and outgoing transaction requests to be processed up to the HIGH threshold values that are predefined by the systems programmers. This is known as the Green Flag Stage.
If the system is experiencing performance problems, AUTOMON/CICS notifies the system console operator of the cause. Simultaneously, it reduces the flow of incoming transactions by decreasing threshold values until the performance problem is resolved. This is known as the Yellow Flag Stage.
In a performance-critical environment – system loop, storage short, max tasks, resource deadlock, ECB permanent wait, storage violation, etc. – AUTOMON/CICS will immediately notify the system console operator of the precise cause and wait for the Action Cycle to expire. The Action Cycle is predefined by your system programmer. After the Action Cycle expires, AUTOMON/CICS takes corrective action to alleviate the problem. This is known as the Red Flag Stage.
The behavior of AUTOMON/CICS matches that of CICS TS. When CICS is experiencing a system abend condition, a repair subtask will be automatically activated to perform corrective actions to prevent a system crash. All major virtual storage areas will be checked and repaired. After the recovery stages are complete, the control task will return control to CICS (dispatcher domain) for continued processing.
