IBM z/OS vs. SUSE Linux Enterprise Server

IBM z/OS, more specifically Omegamon, has access to a lot of relevant information for monitoring but a 90s interface with little or no ease of use and/or maintenance.

SLES is a good fit for running supported enterprise applications like SAP, HANA, oracle,.. We use it to run all our SAP workloads, and so far everything has worked great. All libraries are right in the repository, all documentation is correct and the support answers really fast in case you have problems.

• provides infrastructure metrics
• provides historical transaction behavior
• provides metrics on vital components for z/OS

• Seems Custom made for SAP workloads
• Longest standing collaboration between platform and apps
• SuSE for SAP works seamless on-prem, on SAP Cloud, Azure, AWS & GCP
• Support for oldest SP of SuSE so our customers can run their business without fear

• end-to-end requests
• correlated metrics of vital components
• facilities to consume historical transaction data

• The support window for service packs after a new SP is released is too short.
• Community engagement is low.
• There are times when supported packages fall too far behind and create compatibility issues with applications. The Open Build Service usually provides a way around this, though.

IBM needs to update, modernize and improve the usability of the Omegamon interface

For the breadth of services, features and overall performance, I believe Suse Linux is a great choice for any enterprise. It still has to grow a bit in areas like online help forums and documents, but we are pretty much satisfied with our choice.

It's great for basic support issues. But it's less suited for anything that is either obscure or uncommon, and it is very hard to escalate, unless you've built a relationship with your vendor/salesperson.

Third party training was fast but mostly unnecessary as we were already Unix trained and Linux familiar

SUSE Linux Enterprise Server works well with the SUSE Manager, it really simplifies everything. We also do have SUSE 4 SAP, and the SUSE Manager is able to manage them all, even other (up to date) Linux distributions. Patching has never been that easy and the SALT integration is also working without any problems.

We have successfully deployed on physical servers, VMs and in cloud all over the globe from templates of our own design

• We need to have Observability on the Mainframe

• It allows a very small team to manage a large number of servers, due to its automation and manageability.
• SAP supports it very well, making it straightforward to manage. There are also "recipes" for Oracle which has all of the requisites to install an Oracle DB; which helps with deployment immensely.
• It lets us run large SAP instances in SLES on Power, helping us with support, manageability, and performance.
• Support costs are high, but required for SLES for SAP.
