Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

m_setvalues_layout - set layout values of a LayoutObject
cc [ flag... ] file... -llayout [ library... ] #include <sys/layout.h> int m_setvalues_layout(LayoutObject layout_object, const LayoutValues values, int *index_returned);
The m_setvalues_layout() function changes the layout values of a LayoutObject. The layout_object argument specifies a LayoutObject returned by the m_create_layout(3LAYOUT) function. The values argument specifies the list of layout values that are to be changed. The values are written into the LayoutObject and may affect the behavior of subsequent layout functions. Some layout values do alter internal states maintained by a LayoutObject. The m_setvalues_layout() function can be implemented as a macro that evaluates the first argument twice.
Upon successful completion, the requested layout values are set and 0 is returned. Otherwise -1 is returned and errno is set to indicate the error. If any value cannot be set, none of the layout values are changed and the (zero-based) index of the first value causing the error is returned in index_returned.
The m_setvalues_layout() function may fail if: EINVAL The layout value specified by index_returned is unknown, its value is invalid, or the layout_object argument is invalid. EMFILE There are {OPEN_MAX} file descriptors currently open in the calling process.
Do not use expressions with side effects such as auto-increment or auto-decrement within the first argument to the m_setvalues_layout() function.
