Os commands, oracle user permissions

Question

I installed the objects as outlined in this Oracle whitepaper:
http://www.oracle.com/technology/tech/java/jsp/pdf/calling_shell_commands_from_plsql_1.1.pdf
This allows me to enter os commands from pl/sql using the java method. Works like a charm, except I can not access a directory our linux admin recently granted to the oracle user.
If I run the groups command from a tty session as user oracle, I get:
$ /usr/bin/groups
oinstall newgrp dba
If I run the same thing from sqlplus I get:
SQL> select os_command.exec_clob('/usr/bin/groups') command from dual ;
COMMAND
oinstall dba
I do not have the 'newgrp' group when I run from the db.
The dba bounced the db but no change. I understand the jvm resides in the db kernel. Bouncing the server is not an option at this point.

Hi Stevens,
There is very small reason, to reduce the downtime we are planning to install 10g binaries in on week day and weekend we will take downtime only for upgrade.
so that while upgrading we can exclude the installation time.
Thats why we are planning to create new os level user and installing 10g binaries.
So asked for advice and suggestions whether is it a way to approach.
Thank you very much
VamshiUnderstood, but none of that requires a new oracle user/software owner. I have managed AIX boxes hosting 3 separate db's, each with it's own OHome, owned by it's own OS account. I understand the reasoning of the guy who set that up (that I inherited it from), but disagree with it. It created as many problems as it solved. There really is no good reason that I can see to create more than one single OS account to own all of the oracle software installations. Just as there is generally no good reason to have multiple OHome's of the same version. Just as there is no good reason to have multiple listeners on a given host.
