It's still there. Here's what I wrote up about it in 2001:
FLUSH
This causes a database buffer writers to flush, which would be used to
test for buffer-writer starvation. Use this command when SHOW BUFVARS has
a dpDirty (dirty pages) value in the thousands. Then check log
utilization to see if it freed things up.

Subject: Re: What is the FLUSH command?
It forces a write of used log buffer pool pages to the database. I don't
know if it even still does what it says it is doing in newer versions of
TSM. I'm trying to remember, but I think it was used to free up recovery log
space. With bigger disks being used for recovery logs, it probably isn't
needed, but you don't specify your TSM version or environment. Somebody was
certainly worried about running out of log space though..
It has always been undocumented, however, it might show up in a readme
somewhere.

Hey -
Have started new contract with company and I'm
trying
to figure out what is going on. Several of the
servers have a scheduled "FLUSH" command that runs
daily. Can't find any documentation on FLUSH - what
is it supposed to be doing? The messages along with
the schedule say something about "buffer pool dirty
pages flushed". Any documentation on this anywhere?
thanks,
T.
