Hi;

Have you tried the script starting in background

Code:
cmd &
- When some errors occur cron writes a mail; have you checked this

- you manually recreate the environment, would it be possible to execute the profiles in your script

Code:
# Not forget the point-command ( exec in this shell )
. /etc/profile
. /u/...home/oracle/.profile # or .bash_profile
to get the whole environment

in cron you can explicit direct the stderr and stdout to disk

Code:
cmd  > file.log 2> file.err
Hope it helps

Orca
PS.: i would appreciate to work under TRUE64!
