CloudFrame Relocate provides an easy way to shift COBOL workloads from CPs to a zIIP using cross-compilation. This means that COBOL source code is converted directly into Java bytecode, allowing the executable to run in a zIIP-eligible Java Virtual Machine (JVM). This process is transparent to the code’s existing relationship with data stores and other infrastructure. Therefore, stored procedures don’t have to be rewritten, batch schedulers don’t have to be adjusted, and sort processes can
Mainframe cost optimization is a current buzzword being applied to many different processes and techniques. But let’s face it, optimization in this context inevitably means reduction. The general idea is that companies are looking for ways to reduce the cost of their computing infrastructure. And who can blame them? If you can pay less for something, why not do it? So, what types of things get lumped into mainframe cost optimization? Generally speaking, you can
Regular readers of my posts here know that zIIPs are a type of mainframe specialty processor that augments the general-purpose CPUs. Instead of running all workloads on the general-purpose CPUs, specific workloads are shuttled to the specialty processors for execution. The zIIP, or Integrated Information Processor, was initially created to process certain types of Db2 […]
Units of work that run on the mainframe, at least those running on z/OS, are dispatched using two different types of control blocks: TCBs (Task Control Blocks) and SRBs (Service Request Blocks). It can be beneficial to understand these two types of control blocks, including how they are used, the differences between the two, and […]
Cost is the primary driver for shifting COBOL compute to less expensive platforms. But once organizations decide that they are going to use shifting COBOL compute they discover there are other benefits to this modernization method. These benefits are realized in three areas: impact, risk, and momentum. Financial Impact The immediate benefit of shifting COBOL […]
