Re: ontape back-up/restore to remote device
Neil:
On a restore the tape is open, read to verify that it has the correct
information,
closed to reposition at the begin of the tape, then re-openned. If the
close
did not get completed by the tape device by the time the open is issued any
subsequent reads fail. There is an easy solution to this(if I remeber my
shell script):
1. Create a shell script (lets say /work/bin/tape_wait.sh)
#!/bin/sh
/usr/bin/sleep 60; rsh $*
2. now in you ontape environment set DBREMOTECMD
to /work/bin/tape_wait.sh
Hope this helps,
