Since then IBM has coined the term error recording data set (ERDS) for successor versions that allow the installation to choose the name and for operating systems not derived from OS/360.
The most sophisticated, Machine Check Handler (MCH), records failure data on SYS1.LOGREC and attempts recovery.
The MCH can handle memory failures in refreshable nucleus control sections by reading a fresh copy from SYS1.ASRLIB and can handle memory errors in SVC transient areas by reading a fresh copy of the SVC module from SYS1.SVCLIB.
In z/OS the installation can either use an ERDS or can define a z/OS System Logger log stream[2] to hold the error data.
On Microsoft Windows platforms, in the event of an unrecoverable MCE, the system generates a BugCheck — also called a STOP error, or a Blue Screen of Death.
In some cases, the CPU will shut itself off once passing a thermal limit to avoid permanent damage.
If the failures typically only occur fairly soon after the OS is booted or not at all or not for days, it may be suggestive of a power supply issue.
