You must have an oracle user that is a member of a group named dba. If an oracle user does not exist on the Oracle VM Manager host, enter the following commands as the root user to create the user, create the group, add the user to the group, and set the user's password:
# groupadd dba # useradd -g dba oracle
If the oracle user already exists, add it to the dba group using the following command:
# usermod -g dba oracle
The oracle user must also have a
hard nofiles
and soft
nofiles
minimum of at least 8192, as well as some
other security limits set. To set these, edit the
/etc/security/limits.conf file to include the following:
oracle hard nofile 8192 oracle soft nofile 8192 oracle soft nproc 4096 oracle hard nproc 4096 oracle soft core unlimited oracle hard core unlimited
To configure the oracle user automatically, use the environment configuration script provided with the Oracle VM Manager installer. See Section 3.3.2.4, “Environment Configuration Script” for information on using this script.
