Yes, it would take a lot of work to document how z/OS (or any other operating system) utilizes various hardware features. However, IBM customer’s are on shaky ground, if they build systems based on undocumented features or functions. In the long run, it is probably in IBM’s best interest to document features or functions they know that their customer base is using or wants to use.
Since IBM does not document that z/OS guarantees that the extended TOD clock values will be unique across a sysplex, I would not recommend that someone design their software to depend on it being unique. Their programs should be prepared to handle duplicate values. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
