Environment Variables
2-18 Oracle Application Server Installation Guide
To create the oracle user:
1. Enter a command similar to the following:
# /usr/sbin/useradd -g oinstall -G dba[,oper] oracle
In this command:
– The -g option specifies the primary group, which must be the Oracle
Inventory group, for example oinstall
– The -G option specifies the secondary groups, which must include the OSDBA
group and if required, the OSOPER group, for example dba or dba,oper
2. Set the password of the oracle user:
# passwd oracle
To check which groups an operating system user belongs to, run the groups
command with the name of the user. For example:
prompt> groups oracle
For more information about operating system users and groups, see your operating
system documentation or contact your system administrator.
