Any additional installation owners that use Oracle ASM for storage must also be made members of this group. The central inventory of Oracle installations on the cluster. This path remains owned by grid:oinstall , to enable other Oracle software owners to write to the central inventory. These permissions are required for installation, and are changed during the installation process to root:oinstall with permissions drwxr-xr-x. The command creates the following Oracle Database DB1 groups and users:.
When you install Oracle software, you install it as the user oracle. This allows you to apply certain security and tuning settings to the software without having to change settings for other users on the system. In this section, the oracle userwill is created and the dba and oinstall groups which have special permissions on the software are installed. To set the password for the oracle user, invoke the passwd commandas root passing the username as an argument.
Now that the user and groups are established, just make a handful more of customizations before Oracle can be installed. Oracle uses much more of the system's resources than most applications. Due to this, there may be a need to alter some of the default limits on how the oracle user can use resources.
Each of these changes consists of simply adding lines to the given files using a text editor. With all the requirements out of the way, it is now time to install Oracle! It contains the following topics:. Depending on if this is the first time Oracle software is being installed on your system and on the products that you are installing, you may have to create several operating system groups and users.
However, if you use Oracle Preinstallation RPM to provision your Linux operating system for an Oracle Grid Infrastructure or Oracle Database installation, then it configures an Oracle database installation owner oracle , an Oracle Inventory group oinstall , and an Oracle administrative privileges group dba. If you prefer to allocate operating system user privileges so that you can use one administrative user and one group for operating system authentication for all administrative privileges, then you can use the oracle user as the installation owner, and use one group as the primary group for any user requiring administrative privileges for Oracle ASM, and Oracle Database administration.
This group must also be the Oracle Inventory group. To simplify using the defaults for Oracle tools the group name should be oinstall. You can also create custom configuration groups and users based on job role separation that divide access privileges. Log in as root , and use the instructions in the following sections to locate or create the Oracle Inventory group and a Oracle software owner user:. When you install Oracle software on the system for the first time, Oracle Universal Installer creates the oraInst.
This file identifies the name of the Oracle Inventory group typically, oinstall and the path of the Oracle Inventory directory. You can configure one group to be the access control group for Oracle Inventory, for database administrators OSDBA , and for all other access control groups used by Oracle software for operating system authentication.
However, if you use one group to provide operating system authentication for all system privileges, then this group must be the primary group for all users to whom you want to grant administrative system privileges.
If you have an existing central Oracle Inventory, then ensure that you use the same Oracle Inventory for all Oracle software installations, and ensure that all Oracle software users you intend to use for installation have permissions to write to this directory. To determine if the oraInst. If the oraInst. For example:. A job role separation configuration of Oracle Database and Oracle ASM is a configuration with groups and users to provide separate groups for operating system authentication.
Oracle recommends that you create one software owner to own each Oracle software installation. To create separate Oracle software owners and separate operating system privileges groups for different Oracle software installations, note that each of these users must have the Oracle central inventory group oraInventory as their primary group. Members of this group have write privileges to the Oracle central inventory oraInventory directory, and are also granted permissions for various Oracle Restart resources and directories in the Oracle Restart home to which DBAs need write access, and other necessary privileges.
In Oracle documentation, this group is represented as oinstall in code examples. The Oracle Database, and the Oracle Grid Infrastructure for a standalone server installation owner users oracle and grid respectively must belong to the Oracle Inventory group oinstall. Each Oracle software owner must be a member of the same central inventory group. Oracle recommends that you do not have more than one central inventory for Oracle installations. If an Oracle software owner has a different central inventory group, then you may corrupt the central inventory.
The following sections provide an overview about users and groups to divide access privileges by job roles:. You can create a single user for example, oracle to own both Oracle Database, and Oracle Grid Infrastructure for a standalone server installations.
However, Oracle recommends that you create one software owner to own each Oracle software installation typically, oracle , for the database software and grid for the Oracle Restart owner user. You must create at least one software owner the first time you install Oracle software on the system. You must create this group the first time you install Oracle Database software on the system. This group identifies operating system user accounts that have database administrative privileges the SYSDBA privilege.
Only if you pay for Oracle Support you can download other versions and patches, but they're in another URL. Pull the latest Oracle Linux 7 with the Docker command ' docker pull oraclelinux You can't use Oracle Linux 8 because you will get the error 'An operation requiring remote execution could not complete because the attempt to set up the Cluster Verification Utility remote execution framework failed on the indicated nodes at the indicated directory location because the CVU remote execution framework version did not match the CVU java verification framework version.
The accompanying message provides detailed failure information. The first parameter after the name is to run it privileged since we need to change the file system 'file-max' parameter. The second parameter is to keep the container running forever. The third parameter is to keep STDIN open and allocate a pseudo-tty for interactive processes a shell.
The other parameters are to expose the ports and to the host, and to use the image we pulled in the previous step. The packages libaio and libaio-devel are to avoid the error 'An internal error occurred within cluster verification framework. Note that for Oracle 11g the list of packages is larger.
Increase the maximum stack size with the Linux command ' ulimit -Ss '. By default it is and it must be greater than Change the OS kernel parameter 'file-max' by editing sysctl.
