Mark,

Not from a system standpoint, but from an application standpoint you need 
to check if you're doing DBINFO - mode202 calls to determine space 
available for DBPUT (capacity - number of entries), then you need to 
change to mode205 (maximum capacity - number of entries)

Now that we are flush with disk space (discfree shows 179,000,000 sectors
free), we'd like to enable DDX and MDX on our main MANMAN databases.

Are there any serious "gotchas" with doing so? I know it's key to strike a
balance between a small increment (which will cause greater disk
fragmentation) and a large increment (which runs the risk of failing to
acquire enough disk space, as well as lengthening the pause while the
expansion happens), but are there any other key considerations we must 
look
at?
