when we try to take backup using ontape -s -L 0 command getting error message "Archive failed - buc_fe.c : Archive API processing failed at line 251 for rc "
if i check in online.log it shows me error " invoke_alarm(): /bin/sh -c '/usr3/informix/etc/alaramprogram.sh 3 24 "
MT: cannot allocate memory
" "out of virtual shared memory "

Pl.tell me how to solve thie problem

What is the status of the database - is Informix up and running? Can you access the data with dbaccess??

What backup device do you have setup in onconfig??
