Administration 

Octo uses an M routine to manage the users of the database and other administrative tasks, called %ydboctoAdmin.

Currently Octo user administration consists of user creation and deletion, and setting of user database permissions.

User database permissions are set at user-creation time, i.e. via %ydboctoAdmin add user. If no options are passed to this command, the user is created with read-only permissions. To grant additional permissions, use --readwrite or --allowschemachanges, described below.

ydboctoAdmin 

%ydboctoAdmin allows the user to add, delete and view a list of users with show.

Usage pattern:
yottadb -r %ydboctoAdmin <action> <subAction> <arguments>
<action> is either add, delete or show.

<subAction> refers to user or users.

<arguments> would be the specific arguments passed to the command.

Add 

The following is an example of adding users to the database:
yottadb -r %ydboctoAdmin add user OctoUser
This adds OctoUser as a user of the database, after verifying the password for the user. Unless otherwise specified, new users are created with read-only database permissions.

To grant a user read-write permissions (INSERT, UPDATE, and DELETE) use the -w/--readwrite flag:
yottadb -r %ydboctoAdmin add user OctoUser --readwrite
yottadb -r %ydboctoAdmin add user OctoUser -w
To grant a user read-write permissions and permission to modify schemas (CREATE and DROP), use the -a/--allowschemachanges flag:
yottadb -r %ydboctoAdmin add user OctoUser --allowschemachanges
yottadb -r %ydboctoAdmin add user OctoUser -a

Delete 

The following is an example of deleting users from the database:
yottadb -r %ydboctoAdmin delete user OctoUser
This deletes OctoUser from the list of users in the database.

Show 

The following is an example of the database showing a list of users:
yottadb -r %ydboctoAdmin show users
This shows a list of the users of the database.
