That will only work in ksh. But if that works, so would:
grep "^oracle:" /etc/passwd | IFS=":" read user xpass uid gid gcos home shell

DAEMON(1) Icecream User's Manual ICECREAM DAEMON(1) NAME
iceccd - Icecream daemon SYNOPSIS
iceccd [-n netname] [-m max_processes] [--no-remote] [-w] [-d | --daemonize] [-l logfile] [-s schedulerhost] [-v [v [v]]] [-r | --run-as-user] [-b env-basedir] [-u | --nobody-uid nobodyuid] [--cache-limit MB] [-N hostname] DESCRIPTION
The Icecream daemon has to run on all nodes being part of the Icecream compile cluster. It receives compile jobs and executes them in a ch- root environment. The compile clients send their compile environment the first time they send a job to a particular daemon, so that the en- vironment of the daemon doesn't have to match the one of the client. The daemon also has to run on clients sending compile jobs to the Icecream network. If a node should be able to send compile jobs, but nev- er receive any, start the daemon with the option -m 0. All Icecream daemons need to have contact to the Icecream scheduler which controls the distribution of data between compile nodes. Normally the daemon will automatically find the right scheduler. If this is not the case you can explicitly specify the name of the Icecream network and the host running the scheduler. OPTIONS
-n netname The name of the icecream network the daemon should connect to. There has to be a scheduler running for the network under the same network name. -m max_processes Maximum number of compile jobs started in parallel on machine running the daemon. --no-remote Prevents jobs from other nodes being scheduled on this one. -w -d, --daemonize Detach daemon from shell. -l logfile Name of file where log output is written to. -s scheduler_host Name of host running the scheduler for the network the daemon should connect to. This option might help if the scheduler can't broadcast its presence to the clients due to firewall settings or similar reasons. -v, -vv, -vvv Control verbosity of daemon. The more v the more verbose. -r, --run-as-user Force running the daemon with user rights. Usually you will need to run the daemon with root rights. -b env_basedir Base directory for storing compile environments sent to the daemon by the compile clients. -u, --nobody-uid nobodyuid Id of user nobody. This user id is used when the daemon is dropping privileges. --cache-limit MB Maximum size in Mega Bytes of cache used to store compile environments of compile clients. -N hostname The name of the icecream host on the network.
