I got one answer:

>Try to set DSM_DIR
>export DSM_DIR=/usr/adsm
>sometimes this helps.

but that didn't help, so I ask again:

For IRIX 6.5. with the filesysteem XFS we got from
(ftp.rz.uni-karlsruhe.de) the distribution IP21498.tar
According the README this is Version 3, Release 1, Level 0.6 PTF6.

After installation we get the message:
ERROR: unavailable to open message repositori (/usr/ads/dscameng.txt)

We have the same problem with the client downloaded directly from IBM.

Does someone have a suggestion?

Thanks in advance
