Centralized scheduling has improved automation and reduces manual monitoring for complex workflows
The best features JAMS Scheduler offers are centralized job scheduling, dependency management, and monitoring. I also appreciate the alerts and retry options because they help us handle failures without constantly checking jobs manually. Centralized scheduling makes it easier to manage all our jobs from one place instead of maintaining multiple schedulers or scripts. Dependency management is especially useful for chaining workflows because JAMS Scheduler can automatically trigger the next job only when the required previous step completes successfully. Another useful feature is the monitoring and alerting. If a scheduled job fails or runs longer than expected, we can quickly identify it and take action, which is particularly helpful for production support and reducing manual monitoring. JAMS Scheduler has helped quite a bit with identifying common job failures, missed schedules, dependency issues, and execution errors. The alerts and job history make it easier to identify the failure point and take corrective action without manually checking every workflow. JAMS Scheduler's code-driven automation has been useful for handling more complex scheduling logic and workflows that go beyond simple time-based triggers. It is important for us because we can combine scripts, dependencies, conditions, and parameters to support different production scenarios without creating too much manual intervention.

Unified orchestration has reduced costs and improves governance for complex data workflows
I would say it would be much more helpful if Astro by Astronomer can provide an MCP to use and integrate with Astro by Astronomer and their AI agent Auto, so that we can use our tools like Claude, Code, or Cursor to have a central location where we integrate that MCP in Databricks via the AI gateway, and then we can have a place where we can connect to Astro by Astronomer, Databricks, other tools such as Jira and DataDog, and then have a much more comprehensive analysis and overview and monitoring of the entire data ecosystem. Having an MCP integration would tremendously help us to have a more comprehensive data platform that is more AI-ready. That is one of the features that I can think of. Another thought would be having an integration with Kubernetes instead of just scheduling everything on Astro by Astronomer workers. That would be helpful. One thing I can think of is that the Astro by Astronomer local developer environment can be improved further, but perhaps that is a very niche use case that I have in mind, and it may not be useful for others. There is room for improvement around having an improved UI and also integration with other tools. On governance, I would say we can have a more granular level of governance even inside workspaces. Having much more granular control over people belonging to the same team in Astro by Astronomer could have different access to different DAGs, depending upon our tagging strategy. That is one of the areas I can suggest in terms of improvement. The AI capabilities can be improved further. I would compare the current AI capabilities to newer models provided by Claude such as Opus or Codex.

A continuously evolving, stable solution, with responsive support
The visual whiteboard for design and execution included with the solution is very crucial to those who are new to Rocket Zena, especially so that the learning curve is minimized and they can focus on accomplishing the task. We process our system's payroll through Rocket Zena. The fact that it's a multi-process, multi-layered application, means that we can rely on the solution for kicking off processes, notifying user vendors of the steps, completions, error logging, and historic events from the previous run times. Rocket Zena's ability to automate jobs on the mainframe as a distribution workload automation solution is good. The solution continuously improves over time. We're eager to start the latest upgrade this coming year that'll put us on the cloud. Hopefully, this will improve the product even more. We can run things natively without the scheduler if needed. The solution working properly and up to date without the need for a mainframe scheduler is crucial. We use the solution to manage a few complex operational workflows end-to-end across multiple technology stacks. Rocket Zena does a great job of simplifying our cross-platform processes through automation. The solution helps speed operations up and keeps them automated allowing us to focus on other priorities. The solution helps increase our completion rates by working overnight to meet our SLAs. Rocket Zena completes 30 percent of our workload outside of our standard work hours. Rocket Zena's cross-platform job scheduling helped us save around 40 percent of programming time by automating repetitive tasks. We use the solution to transfer our current files and keep up with our infrastructure on a few automated jobs, such as refreshing our database which happens overnight. The solution helped free up around 15 percent of our engineer's time to focus on more value-added work.

Quotes from Members

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

Pros

"JAMS has improved our productivity immensely because everything flows. I don't think we could operate at our current staffing levels without it."
"The most valuable aspect of JAMS Scheduler is that over two and a half years, I have never come across any issues when running the jobs."
"Being able to create a series of chained jobs, which are basically linked jobs is valuable."
"While I appreciate the other features, the agent stands out for its ease of installation and configuration for JAMS monitoring."
"One of the things I like the most, as a SQL DBA, is the fact that we can manipulate tables in the background. Also, the fact that you can have your own views and work with the product the way it fits best is a very helpful feature."
"JAMS has positively impacted our organization by saving us time, reducing errors, and improving workflows."
"We have over 50 jobs running daily to manage all the integration of our systems and we don’t have to monitor these jobs; they just run, JAMS centralizes the management of jobs in our environment, has streamlined our monitoring, saves us about four hours a week in troubleshooting time, and has helped free up about eight hours a week of IT staff time."
"I didn't know about JAMS because I don't have a person with any challenges with the purchase administration. The feature or the user interface is user-friendly because of the readable icons or very descriptive icons. Though I'm a beginning user of JAMS, I had no issues using it."
"Astro by Astronomer has positively impacted my organization because it is reliable, allowing me to depend on it for managing the Airflow instances along with the infrastructure and error handling."
"Astro by Astronomer has positively impacted my organization because it continuously follows the latest version of Airflow as an open-source project."
"The positive impact of Astro by Astronomer has mainly been on team productivity and the standardization of development."
"The best features Astro by Astronomer offers, in my opinion, are easy setup and good tutorials."
"The best features Astro by Astronomer offers include a large operator and library that I can work with for different use cases."
"Astro by Astronomer has had a positive impact on my organization mainly in terms of time savings and error reduction, since I seek to standardize all the processes within my framework."
"Previously, developing DAGs took days and sometimes a sprint, now I can deliver within a couple of hours."
"I saved a significant amount of time compared to my previous setup as I deployed Astro by Astronomer on my local machine in about five minutes, whereas with the Airflow documentation it took much more time and was very painful compared to the Astro by Astronomer deployment."
"I have found the scheduling feature the most valuable, as I can map dependencies by using ASG-Zena and it gives a nice, quick visualization as to where things are."
"The most valuable feature is the FTP file transfer."
"In the latest upgrade, Zena added a web-based client. The more I use it, the more I like it. It's an excellent interface. They do a good job of steadily improving the solution to make it more useful."
"Its FTP feature is very good, as is scheduling any process or task with the Zena client. I have found it to be very helpful. If a task fails, it gives you a prompt."
"Once you master it, it's a pretty good tool."
"From a Linux configuration point of view, Rocket Zena is straightforward. It's fairly easy to set up the server and agents once you know how to do it."
"You can click Ctrl-G and bring a diagram view. You're able to view in a diagram format. The view that it provides is easy, and you can move to the left, up, or down. You can double-click on a certain process. It'll drill into that process and all of its underlying components. You can double-click on an arrow or a component, and it'll bring up a screen that'll have all the variables that are assigned to that particular piece, as well as the values at run time. So, the diagram feature of it, at least for me, is pretty valuable."
"I like the whole product, but specifically, I like the license part. It's very easy to acquire a license for this product."
 

Cons

"As an admin, I would like to have a web-based GUI instead of a client application that we have to install on our PCs."
"JAMS lacks source control features. Our previous solution had job control language, but JAMS doesn't. When migrating between versions, JAMS doesn't migrate all the data, like job change history, etc. Also, the scheduler doesn't have a way to make jobs invisible, so you can temporarily turn a job off if you decide not to run it today."
"One thing that I know that the JAMS people said that they were working on that would be huge for us is a search capability so that you could search for tasks. It may be available in version 7 or in a future release of 7. I think that's on their roadmap. But right now, for us to do a search, we have to search through database queries."
"All my machines at work are Macs. JAMS client is a Windows-based thing. It is all built on .NET, which makes perfect sense. However, that means in order for me to access it, I need to connect to a VPN, then log onto one of our Azure VMs in order to access the JAMS client. This is fine, but if for some reason I am unable to do so, it would be nice to be able to have a web-based JAMS client that has all the exact same functionality in it. There are probably a whole bunch of disadvantages that you would get with that as well, but that is definitely something that would make life easier in a few cases."
"Fortra is getting much better with documentation and examples, but there is still room for improvement."
"The biggest area with room for improvement is the area that my organization benefits the most from using JAMS, and that is in custom execution methods. I happen to have a very good C# developer. Ever since we got JAMS, he has spent a lot of time talking to JAMS developers, researching the JAMS libraries, and creating custom execution methods. He's gotten very good at it. He is now able to create them and maintain them very easily, but that knowledge was hard-won knowledge. It was difficult to come by, and if I should ever lose this developer, then I would be hard-pressed to find anyone who could create JAMS custom execution methods quite as well as he can since there really isn't all that much help, such as documentation or information, available on how to create custom execution methods."
"All my machines at work are Macs. JAMS client is a Windows-based thing."
"I would like a simple web interface that I could give to my team to go in and kill jobs or see why jobs died so that we don't have to drill down deeper into the application and know everything about it. It would be good to have a really clean web engine that would say here are the jobs running. We can then click to see the time running and whether any of them fails and other similar things. I know they have one, but it's not very simplistic."
"Astro by Astronomer can be improved always by integrating and being in attention with the capabilities that are emerging in the technology as well."
"I believe my experience with pricing, setup, cost, and licensing could be better."
"I believe one area for improvement for Astro by Astronomer would be to further expand the documentation and examples for more advanced scenarios, especially involving integrations with AWS, Amazon ECS, AWS Fargate, and Astronomer Cosmos."
"If I had to pick one thing that could be improved, it would be the speed when working in clouds."
"I would recommend making it easier to read the logs in Astro by Astronomer because the logs are pretty hard to follow, especially for the pipelines that are processing much data, such as our DBT, where we have issues finding something in the logs."
"The documentation part of Astro by Astronomer can be made easier and more generic, not specific to the integration with each of the services."
"Sometimes we experience performance bottlenecks, depending on the time we are running DAGs simultaneously."
"Astro by Astronomer is doing great, and while improvement opportunities exist, particularly around the cost model, which can occasionally feel steep, I generally find it quite favorable."
"The documentation has room for improvement."
"Rocket Zena is a mainframe-based job scheduler. I would like it to be more open so that we can use it on a distributed platform."
"Another one that is probably a little bit bigger for me is that when there is an issue or there's an error, it writes on a different screen."
"The scheduling mapping is a little disjointed. There is no wizard-type approach."
"In the web interface, it stacks the tasks across the top, and they accumulate until you close or clean those out. That seems a little cumbersome. You must right-click and close all tabs constantly to keep the console clean and manage your views."
"One area where it could be improved is communication between the different servers. Sometimes there are processes that have already been completed but we get a status notification that they're still active."
"Another one that is probably a little bit bigger for me is that when there is an issue or there's an error, it writes on a different screen. I have to find the actual process name and go to a different screen to view the alert that got generated. On that screen, everyone's processes, not just the processes of the folks in my department, are thrown. It takes me a while to find the actual error so that I could go in there and look at the alert. It could be because of the way it was set up, but at least for me, it isn't too intuitive."
"In the next release, I would like the user experience to be improved. The user interface should be more appealing to gen-z."
 

Pricing and Cost Advice

"The licensing model for JAMS is straightforward and based on the number of agents, not the number of jobs you run. It's cheap and fairly simple."
"The pricing is reasonable."
"The product is reasonably priced, and we don't have any add-ons."
"Fortra's JAMS pricing structure has deteriorated significantly since its acquisition by Fortra."
"It's expensive, to be honest, but it does the job."
"It's certainly a lot cheaper than Tivoli and Control-M. In comparison to them, you get a lot more bang for your buck. You get pretty much the whole functionality and more, in some cases, when compared to Control-M, but at a fraction of the price."
"All licensing models are a little overpriced, but JAMS offers a good value, especially given their support response times and ability to handle unforeseen issues like the SFTP transfers. I hope to find more use cases to get a better bang for our buck."
"In the end, you'll find that it's really worth the price. There is some sticker shock, but it's worth every dime."
