Understanding Groups

Hi

Code:
cat /etc/group :
....
oinstall:x:401:
dba:x:400:oracle
...

cat /etc/passwd|grep oracle 
oracle:x:130:401::/home/oracle:/bin/ksh

1. Is that mean that :
ORACLE user has OINSTALL as it Primary group and DBA as secondary group ?

2. What is the linux comman to set ORACLE user with primary group OINSTALL and DBA as it secondary group ?

Thanks

NAME
groups - print group membership of user SYNOPSIS
groups [user]... DESCRIPTION
The command groups prints on standard output the groups to which you or the optionally specified user belong. Each user belongs to a group specified in /etc/passwd and possibly to other groups as specified in /etc/group. Note that /etc/passwd specifies the numerical ID (gid) of the group. The groups command converts gid to the group name in the output. EXAMPLES
The output takes the following form: example% groups tester01 tester02 tester01 : staff tester02 : staff example% FILES
/etc/passwd /etc/group ATTRIBUTES
