As many Oracle Database Administrators, I am a regular user of Oracle Enterprise Manager in order to monitor or administer my client’s databases.

Anyway, workshops and hands-on-labs were very interesting especially if you like to mix theory and practice. But I had to admit sometimes we got in trouble to keep up…

By | Database Administration & Monitoring, Postgres | No Comments

PostgreSQL 12 is under development but tests can be done. Steps to install this version can be found in this dbi blog . Many thanks to Daniel. While reading the documentation I found that there is a new parameter for pg_upgrade. This new parameter is –socketdir. Why this parameter?
