Help! Lost on Z!

Is it a misconception that mainframe professionals find it hard to get help?  When we talk about non-mainframe technology, there seems to be a myriad of platforms with impressive worldwide community support, actively helping each other on a daily basis.  In other words, what you find there is, if you are struggling to find an answer to a problem, or simply trying to find some better ways do something, then you generally post a question online and seek feedback from the community. Do we mainframe professionals lack such an ecosystem? Is it because of a lack of enthusiasm from experts to chime in on discussions to help out? Is it because of a lack of a solid single social media platform to discuss our challenges? Or is because there are too many platforms, and that we all are stretched too thin on each one, and thereby lack strength in numbers to have meaningful discussion?

Special engines that save cost on the Mainframe!

Do you know that mainframe systems have several kinds of engines (i.e., processors) not just a Central Processor (CP)?  Early mainframes had only one processor – the Central Processing Unit (CPU).  As the mainframe industry evolved over the decades, today’s systems have a Central Processor Complex (CPC) consisting of several different processor types.  Each processor type is used for a specific purpose.  Technically, all processors are the same out of the box, but are configured as specific engine types during installation, or at any time later by IBM.  Unlike CPs, which can be configured to run at lower speeds for software cost reasons, specialty processors usually run at full speed.

Does your Mainframe need an oil change?

Performance management is a key consideration on any platform.  A system may have several resources (CPU, I/O, storage, network etc.) that collectively work together to process a workload. To assess overall health of the system, mainframe system reports can be reviewed on certain key performance metrics on these resources. These metrics are measured and compared against the service level agreements (SLA), or performance Rule-of-Thumb standards.
