Creating a Database Name and Password
Database Names
Database names must conform to the following rules:
- Be between 1-30 characters
- Begin with a letter
- Follow with any combination of letters (upper and lowercase), numbers, and/or underscores.
Database names are case sensitive; however, OpenText strongly recommends that you do not create databases with names that differ only in case. For example, do not create a database called mydatabase
and another called MyDataBase
.
Database Passwords
Database passwords can contain letters, digits, and special characters listed in the next table. Passwords cannot include non-ASCII Unicode characters.
The allowed password length is between 0-100 characters. The database superuser can change a Vertica user's maximum password length using ALTER PROFILE.
You use Profiles to specify and control password definitions. For instance, a profile can define the maximum length, reuse time, and the minimum number or required digits for a password, as well as other details.
The following table lists special (ASCII) characters that Vertica permits in database passwords. Special characters can appear anywhere in a password string. For example, mypas$word
or $mypassword
are all valid.
Caution: Using special characters outside of the ones listed below could cause database instability.
