IBM DevOps Code ClearCase vs. OpenText Network Node Manager i (NNMi)

IBM Rational ClearCase might be better suited for a smaller / simpler code base. Larger code bases really slow it down... but then again there are better alternatives out there for source control

Well-suited for large-scale deployment without needing more servers. Linux installation is quite stable, and Polling of a large number of devices is well managed. Less suited to Network Observability scenarios or cloud network monitoring.

• Rational ClearCase is excellent for handling versioning and branching. No other tool I've used has the depth that ClearCase has when it comes to handling complex branching scenarios and identifying where certain versions of particular files are within a particular configuration.
• Rational ClearCase handles parallel development of many dependent applications really well.
• The use of ClearCase Views to switch between projects and configurations is extremely convenient as opposed to the local workstation model of the competitors.

• Fault and Performance Monitoring
• Performance Reporting
• Alerting and Flexible threhsolds
• Product stability

• Extremely buggy.
• Sometimes the repository gets locked for no reason.
• Slow.

• More out of the box monitoring parameters features
• Improved GUI
• Independent reporting functionality within NNMi

NNMi's user interface is described as well-designed and intuitive, making it easy for users to navigate and perform tasks quickly, thereby enhancing the overall user experience. The system offers a powerful network discovery mechanism that maps out your network's physical and virtual topology, enabling you to visualize connections between devices and identify potential issues. Fault monitoring is at its best. NNMi provides a unified environment for viewing faults, availability, and performance data, consolidating essential information into a single platform.

Support is long and arduous and often are unable to help resolve the issue. We often have to do escalations or duty manager to get things moved. Even with a technical account manager, we do not see much improvement from a support point of view. This is an area where Micro Focus has a lot of improvement to do.

If development is centrallized to one location and your company releases hundreds of customized versions of your software per year, then ClearCase is the best tool for managing the complexity of multiple versions of customized software. If your company has globally distributed development, then I'd recommend Team Foundation Server over ClearCase. If your organization uses Agile Methodologies, then I'd recommend TFS with GIT.

Even though there are many products in the market such as from Solarwinds, CA Spectrum (no DX Spectrum), PRTG that offers similar or even with more flexibility the fault and performance monitoring still Micro Focus is a very nice tool when it comes to Scalability and Stability with all necessary monitoring coverage. There is no external database required and hence less issues with integration.

• Managed code versioning for many years.
• Only one person can edit code at a time - slows processing down.
• IBM is an expensive product to support.

• HP NNM is very good at producing root cause analysis. MTTR is reduced with NNM.
