Also there are more than one package with the same sequence number.
so in my script I start the packages with the same seq num at the same time by running in the backgroud and also until the previous seq is executed the next seq wont be picked up...
once the packages are called the first thing they do is populating the
time in a table when the package is called for execution...
from observation I can see that the theres a difference in time when shell has started the package execution and the time populated in the table(considerably in sec .....5-8 sec)
Also....sometimes all the packages with the same seq number are not populated with the same timestamp upon the execution(all packages with the same seq num are executed in the background simulatneously )...
So my overall cycle time is affected as half of the time is wasted in the lag time ...
Can anyone suggest why theres is a considerable lag in calling of packages and the best possible solution to avoid this lag ?
Thanks in anticipation ,
Regards
Navatha
please can ayone let me know why the same timestamp is not populating....

In LINUX(CentOS, RedHat) is there a way to have the banner statement appear before the logon instead of after the logon? In UNIX and Windows the banner appears before a person actually logs on, what I'm seeing in LINUX is that it appears after the login(ftp, telnet, SSH).

dpkg-preconfigure
DPKG-PRECONFIGURE(8) Debconf DPKG-PRECONFIGURE(8)
NAME
dpkg-preconfigure - let packages ask questions prior to their installation
SYNOPSIS
dpkg-preconfigure [options] package.deb
dpkg-preconfigure --apt
DESCRIPTION
dpkg-preconfigure lets packages ask questions before they are installed. It operates on a set of debian packages, and all packages that
use debconf will have their config script run so they can examine the system and ask questions.
OPTIONS
-ftype, --frontend=type
Select the frontend to use.
-pvalue, --priority=value
Set the lowest priority of questions you are interested in. Any questions with a priority below the selected priority will be ignored
and their default answers will be used.
--terse
Enables terse output mode. This affects only some frontends.
--apt
Run in apt mode. It will expect to read a set of package filenames from stdin, rather than getting them as parameters. Typically this
is used to make apt run dpkg-preconfigure on all packages before they are installed. To do this, add something like this to
/etc/apt/apt.conf:
// Pre-configure all packages before
// they are installed.
DPkg::Pre-Install-Pkgs {
"dpkg-preconfigure --apt --priority=low";
};
-h, --help
Display usage help.
