Improving Data Access
Application programs usually access data in a very predictable manner. Generally speaking, a
DBFIND to an IMAGE dataset is followed by one or more mode 5 or 6 DBGETs. This
predictability is true for a variety of other calls. NetBase makes use of these facts when servicing
calls to remote files and databases.
When NetBase services a call to a remote file, the results of that and any anticipated subsequent
calls to that file are returned to the requesting user’s NetBase buffering area. Only the results of the
original call are returned to the user. Subsequent calls to that file can now be serviced locally using
the buffered data until data outside the buffer is requested or the user performs an activity that
requires flushing the buffer.
The performance increase is dependent upon the application. Increases can range up to 10 or more
times faster than RFA. With NetBase, printing to a remote spooled device is accomplished in a
fraction of the time and consumes fewer valuable system resources.
