$HOME Not Getting Set for Oracle Scheduler Script at Runtime
Post 302151276 by shew01 on Friday 14th of December 2007 07:31:07 AM

Can you elaborate a bit--I don't understand what you mean. Can you specifiy the file names that are called during the login process?
Apparently, Oracle Scheduler is even more lightweight. It barely impersonates the user. 
I can hardcode some syntax to get around this problem, but we'll need to "rip and replace" a bunch of code if the user changes in the future, or if the disk farm changes, or if whatever else changes.... I'd like to keep the configuration generic and let the system to figure out $HOME at a minimum, and it would be nice if it would populate $SHELL too. From there, I should be able to source whatever other scripts that I need.
Is there a way to figure out which shell is running when $SHELL is not populated?

chsh
CHSH(1) User Commands CHSH(1) NAME
chsh - change login shell SYNOPSIS
chsh [options] [LOGIN] DESCRIPTION
The chsh command changes the user login shell. This determines the name of the user's initial login command. A normal user may only change the login shell for her own account; the superuser may change the login shell for any account. OPTIONS
The options which apply to the chsh command are: -h, --help Display help message and exit. -s, --shell SHELL The name of the user's new login shell. Setting this field to blank causes the system to select the default login shell. If the -s option is not selected, chsh operates in an interactive fashion, prompting the user with the current login shell. Enter the new value to change the shell, or leave the line blank to use the current one. The current shell is displayed between a pair of [ ] marks. NOTE
The only restriction placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker is the superuser, and then any value may be added. An account with a restricted login shell may not change her login shell. For this reason, placing /bin/rsh in /etc/shells is discouraged since accidentally changing to a restricted shell would prevent the user from ever changing her login shell back to its original value. FILES
/etc/passwd User account information. /etc/shells List of valid login shells. /etc/login.defs Shadow password suite configuration. SEE ALSO
chfn(1), login.defs(5), passwd(5). User Commands 06/24/2011 CHSH(1)
