4.6 Performance Enhancements
V8.4
The following performance enhancements have been made to the OpenVMS
Version 8.4 release.
4.6.1 Enhancements to Write Bitmaps
V8.4
Write Bitmaps (WBM) is a feature used by OpenVMS during minimerge and
minicopy operations of Shadowing minimerge and minicopy. Information, about
which blocks on a disk are written, is transmitted to other nodes within the
cluster. The following updates have been made in this release.
4.6.1.1 WBM_MSG_INT Parameter Updates
V8.4
The WBM_MSG_INT parameter indicates the time by which a SetBit message
can be delayed when it is in buffered mode. If the SetBit buffer does not fill with
SetBit messages by this time interval, then the message is sent. The parameter
is in milliseconds, however, the conversion factor used for this timer was off by
a factor of 10. Earlier, a WBM_MSG_INT value of 10 was resulting in a 100
millisecond delay when in buffered mode. This problem is corrected so that a
value of 10 now indicates only a 10 millisecond delay.
4.6.1.2 WBM_MSG_UPPER and WBM_MSG_LOWER Parameter Updates
V8.4
WBM_MSG_UPPER is the threshold used to determine if a switch should occur
to buffered message mode, when operating in single message mode. If WBM_
MSG_UPPER or more SetBit operations are done in a 100 millisecond window,
the messaging mode will be switched to buffered mode. The default value is 80.
