I was reading about the New Option and command changes
 in TSMV5.3.

The following options were removed. If you have them specified in your
options file, they will no longer have an effect, but no error messages
will be issued. They should be removed from your options file.

Removed options: SELFTUNETXNsize, USELARGEBuffers, AIXDIRECTIO


Does anyone know If these options were Replaced? Or were they just
removed?

Thanks for any replies!
