V6.3-001 brings important and useful enhancements to GT.M.
GT.M provides a fast and efficient mechanism for processes to opt-in to share their database access statistics for other processes to monitor. The statistics are the same as those available to the process itself using the ZSHOW "G" command.
MUPIP FREEZE -ONLINE freezes database writes from global buffers to the filesystem, while allowing applications to continue database updates as long as they are able to, without requiring a write to the database filesystem. During this time, journal writes continue, ensuring database recoverability.
There are multiple optimizations for performance, some applicable to all platforms, and others specific to Linux on x86_64.
GT.M accepts routines with <CR><LF> line terminators. FIS thanks the participants of the 2016 "Hacking GT.M" workshop for this enhancement.
As always, the release bring numerous smaller enhancements, and fixes. These, and the enhancements referred to above with their change tracking numbers are discussed further in the Release Notes (http://tinco.pair.com/bhaskar/gtm/doc/articles/GTM_V6.3-001_Release_Notes.html).
