Thanks Ahamad,
But this does not seem to be working for me. Please provide alternatives.
Looking to run the below in parallel on all databases, rather then one after one
In a korn shell script, how can I run several processes in parallel at the same time?
For example, I have 3 processes say p1, p2, p3
if I call them as
p1.ksh
p2.ksh
p3.ksh
they will run after one process finishes. But I want to run them in parallel and want to display "Process p1... (3 Replies)

If so wot would be the efficient way to run the jobs... (5 Replies)

YPPUSH(8) NIS Reference Manual YPPUSH(8)NAME
yppush - force propagation of changed NIS databases
SYNOPSIS
/usr/sbin/yppush [-d domain] [-t timeout] [--parallel # | --port port] [-h host] [-v] mapname...
DESCRIPTION
yppush copies updated NIS databases (or maps) from the master NIS server to the slave servers within a NIS domain. It is normally run only
on the NIS master by /var/yp/Makefile after the master databases are changed. /var/yp/Makefile does not invoke yppush by default, the
NOPUSH=true line must be commented out. yppush first constructs a list of NIS slave servers by reading the NIS map ypservers within the
domain. A destination host (or a list of hosts with multiple -h commands) can also be specified on the command line. A "transfer map"
request is sent to the NIS serger at each slave, along with the information needed by the transfer agent ypxfr(8) to callback to yppush,
which may be printed the result to stderr. Messages are also printed when a transfer is not possible; for instance when the request message
is undeliverable.
To specify a port number or use any other yppush options you can edit /var/yp/Makefile directly.
OPTIONS -d domain
Specify a particular domain. The NIS domain of the local host system is used by default. If the local host's domain name is not set,
the domain name must be specified with this flag.
-t timeout
The timeout flag is used to specify a timeout value in seconds. This timeout controls how long yppush will wait for a response from a
slave server before sending a map transfer request to the next slave server in the list. By default, yppush will wait 90 seconds. For
big maps, this is not long enough.
--parallel #, -p #
yppush normally performs transfers serially, meaning that it will send a map transfer request to one slave server and then wait for it
to respond before sending the next map transfer request to the next slave server. In environments with many slaves, it is more
efficient to initiate several map transfers at once so that the transfers can take place in parallel. It is not possible to run in
parallel and assign a fixed port with the --port flag
--port port
specify a port for yppush to listen on. By default, yppush will ask portmap(8) to assign it a random port number. It is not possible to
assign a port with this option and run in parallel with the --parallel or -p flag
-h host
The host flag can be used to transfer a map to a user-specified machine or group of machines instead of the list of servers contained
in the ypservers map. A list of hosts can be specified by using multiple instances of the -h flag.
-v
Verbose mode: causes yppush to print debugging messages as it runs. Note specifying this flag twice makes yppush even more verbose.
SEE ALSO domainname(1), ypserv(8), ypxfr(8)BUGS
The mechanism for transferring NIS maps in NIS v1 is different that that in NIS version 2. This version of yppush has support for
transferring maps to NIS v2 systems only.
