ontape -c error

when i'm running ontape -c over a informix IDS 7.30 UC3 and HPUX 10.20 i received an error like this "shmat: [22] operating system error" repeated 4 times i think this occurs when a logical log is full, and the ontape command backup it, then comes the error to screen. i tried : - changing the block size of the tape. - redirecting to /dev/null. but nothing changes. does anyone know why? Thanks in Adv. Ruben

You do not have enough share memory permitted in the kernel configuration. You will have to increase all the shm parameters in the kernel SYSTEM file and build and boot a new kernel. Check the release notes for values that work. Art S.
