Here's a summary of the questions and answers discovered:

* Is there a way on Solaris boxes to adjust sliding windows? TCPWINDOW doesn't
  seem to work in dsm.sys on the Solaris-based clients.

  Unknown. Possibly just simply not supported for Solaris, but is for AIX.

* What's the appropriate way to exclude a directory and everything under it?

  Set up lines like this in the inclexcl file:

  exclude.dir /opt/foo

  (or exclude.fs if it's on its own fs)

* Is it possible to rename the ADSM server's name? (Not machine hostname,
  but its ADSM name) Or am I just out of luck short of a total reinstall?

  adsm> set servername <new name>

  set this in dsm.sys on all clients

* Where do I obtain latest ADSM and TSM server and client fixes? Is there
  a FTP or HTTP site?

  ftp://index.storsys.ibm.com/adsm/fixes/v3r1/aixsrv/

  3.1.2.90 is the final maint release for 3.1.2. EOL was 31 Jan 2001.

  For TSM patches:

  ftp://index.storsys.ibm.com/tivoli-storage-management/patches

  For TSM maint levels:

  ftp://index.storsys.ibm.com/tivoli-storage-management/maintenance

* Is there any way to temporarily disable paging (ie, <ENTER> to continue)
  within dsmadmc when wanting to gather data for easy copy-n-paste? At least
  one command's output looks very poor when done in batch mode with stdout
  redirected to a file.

  # dsmadmc -id=<id> -password=<pw> -{comma|tab} -out=<output file> <cmd>

* Where can I find documentation pertaining to my version of ADSM server?

  /usr/share/html
  /usr/share/pdf
  ADSM install CD

Now I'm on the right path. :) I do believe we will be migrating to TSM v4
shortly... but for now, needed to deal with any more immediate ADSM v3 support
issues here (especially since it's EOL'd!).

Very interesting processing of the includes/excludes - duly noted and just
means that I'll have to carefully study those some more for the more
interesting (and pathological, heh) cases.
