thanks to all that replied to my question regarding compression - the cause of the problem was the double-compression by TSM and the drive.
Now I've another question:
I'm writing some scripts using dsmadmc with the select command to retrieve data from the TSM database. At this time I've to use various grep commands to remove the headers and footers from the dsmadmc output.
Is it possible to suppress those headers & footers and get only the data returned by the select command?
I did not find an option for this in the manuals.
Thanks again
Bernd
