Easy to install and use with good support and

It's too early to say what improvements are needed, but I can only say we are happy with our decision to move to TMON. We haven't looked at the graphic tools so far, but they're on our to-do list for this year. We will see what happens after the move to Rocket Software. We haven't seen any missing information about our daily work and analysis of our production systems and applications. We're like it to be possible to move some more workload to our ZIIP processors to save us some billing for general workload.

Rocket Software

ASG-Zebb handles reruns automatically with precision and accuracy, all without
changes or modifications to Job Control Language (JCL). ASG is proud to offer the
generational restart functionality as a main feature of ASG-Zebb. This industry
exclusive capability allows accurate reruns of previous jobs regardless of whether
or not that job occurred several days, or several cycles, ago. By eliminating manual
intervention, ASG-Zebb ensures that jobs will use correct datasets and will be
completed virtually error free.
ASG-Zebb automatically recognizes when an abended job is being rerun. It provides
the user with precise information and then efficiently determines the most logical
restart point – usually at the point of failure. In addition, ASG-Zebb works seamlessly
with other job scheduling tools, such as ASG-Zeke, to restart jobs.
