[p4] Very big Perforce file : db.have

[Jamison, Shawn]

I've just reduced my db.have from just over 12 Gigs to about 6 Gigs
doing a restore from checkpoint.  Actually I shaved almost 12 Gig's
total from my P4ROOT directory by doing a restore from checkpoint.

I highly recommend you do a restore.  You'll be surprised.

Andres,
	Perforce supports db.* files greater than 2GB on the platforms
listed at this page:

http://www.perforce.com/perforce/technotes/note053.html

db.have keeps track of what versions of files are in what clients, so
obviously it pays to get rid of unnecessary clients.  However, Perforce
doesn't ordinarily compact db.* files when data is deleted -- it simple
creates "holes" in the data which may or may not be reused.  It's a good
idea to periodically checkpoint and delete the database files, and
recreate the database from the checkpoint.  This will compact any dead
space in the files.  For best performance, it is a good thing if you
have enough memory in your server that db.have can be held entirely in
memory.

Tony.
