This is an original planning guide. It is not a vendor manual, an official standard, or legal advice. Example addresses use documentation ranges. Review every command before you paste it.
What this hour is for
A roadmap is a sequence you can practice: read a backup and restore it on a copy, read a plan, and read a grant. This page does not name a browser tool. The pillar it belongs to links the calculators for the neighbouring work.
This is not an exam and not an official certification. One skill, on a lab you can rebuild. The rollback is the copy you took first. Do not practice on a database you do not administer.
192.0.2.10, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. A sample password is replaced. It is not a password you keep.
The change you can finish
Apply nothing while you are writing the note. When the lab window opens, it is one change on the database named in the ticket. Read the draft, then the database, then decide.
Rollback is the backup, the file, or the snapshot you saved first. You do not invent a rollback after the only copy is gone.
- Name one skill.
- Name the lab.
- Name the rollback.
- Do not touch a database you do not administer.
- Stop.
Mistakes that outlive the statement
DBA Roadmap goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.
- The page treated as a certification.
- Practice on a production database.
- No rollback written.
- Several skills started in one hour.
Decisions to write down
One decision for DBA Roadmap: One skill is written. The lab is named. The rollback is named. And the database is yours.
Checks before you call it done
Confirm this before you call the change done: One skill is written. The lab is named. The rollback is named. It is not a certification. And the database is yours. If one of those fails, stop.
Before you leave the database
DBA Roadmap ends when the database in the prompt is the database in the ticket. If it is not, you are on the wrong database. Stop.
The draft stays a draft until a person has read the names in it. A generator does not log into the database. You delete a line that names a host, a database, or an account you did not write down.
192.0.2.10, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. They belong in the note. They are not values you leave on a database because a draft included them.
prompt-for-this is a reminder that a secret is missing. It is not a password, a key, or a token you save in the ticket or in git. A sample password in a draft is replaced. It is not a password you keep.
One change is the window. If two things move and the result is wrong, you will not know which one did it.
If the same step fails twice, stop for the day. Restore the copy you took first.
A second person reads the database name and the change aloud. If they cannot find them in the ticket, the note is not done.
This page is a planning guide. It is not a vendor manual, not an official standard, and not permission to touch a database you do not administer. You do not disable authentication, a firewall, or TLS to make a check pass.
