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.

Works

The service level and automated capacity manager functions allow us to control priorities, support SLA's and manage our 4HRA and reduce MLC for some software bills.

There currently is a WUI that allows an operator a single pane of glass to see how TM is performing to meet service policies within a JESMAS environment. This is a new feature and multiple individuals have expressed desire to not only see real time monitoring, but the ability to historically go back at least several hours or possibly an entire day to review history.

Good stability but it is lacking the ability to see historical information

We can only see online information but there isn't any historical data to see something that happened a few hours previous. We don't have the ability to access that information. Previously, with MainView, we could look back at information from two days before and get information. We could easily get information from Plexus. Now, we don't have a single screen to check which has been annoying. Compared to MainView, Tivoli is rubbish. We are forced to use this solution. We couldn't stay with MainView. I would like for it to be easier to check the system performance. It should have the ability to see historical data. We can't see the percentages to see the percentages of the CPU utilized. We should be able to see how much was used by our part of the system. Now, we have to continuously recalculate that information.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The report writer in TMON is a very good add-on for batch reports which weren't available in OmegaMon/CICS."

"The integration of IMS commands is very useful, because you do not have to switch to another tool to problem solve solutions."

"Enabled me to solve production problems faster or even avoid them preemptively with warnings."

"Batch smoothing our 4HRA and implementation of group capacity profiles has allowed us to run sub-capacity and lower our MLC."

"MainView has enabled me, in the past, to solve production problems faster, or even avoid them preemptively with warnings."

"It's stable enough. I haven't noticed any problems since it was installed."

Cons

"We're like it to be possible to move some more workload to our ZIIP processors to save us some billing for general workload."

"More visualisation and support for mobile devices would be good."

"An expansion for distributed systems would be great, but probably not workable."

"More visualisation and support for mobile devices would be good."

"Compared to MainView, Tivoli is rubbish."

"We can't see the percentages to see the percentages of the CPU utilized. We should be able to see how much was used by our part of the system. Now, we have to continuously recalculate that information."
