Hot, warm, cold[edit]

ǪŲΌЭЭЁжжЄ I added a new page for fail back, which redirects to this apge (Failover). Failback could possible become its own article in future, or they could be merged. --СђrΐsτσρhΞr ScЋδlτξη 11:38, 21 October 2006 (UTC)

Difference between Mirroring, Failover, Clustering and Load balancing?[edit]

What is the difference between Disk mirroring, Failover, High-availability clusters (a.k.a. Clustering?) and Load balancing?

I would like to see a concise comparison of concepts across all of these pages, as all of these concepts seems tightly bound, and perhaps some of them are identical.

Failover vs. Switchover[edit]

I've worked in IT for over 20 years, and I can't say I've ever run into the distinction made here between 'failover' (automatic) and 'switchover' (manual). I have always heard failover used for both. How widespread is the distinction? (talk) 17:07, 13 August 2010 (UTC)

Oracle uses the term 'switchover' for a manual planned role reversal of a Primary and Standby database, such as for routine maintenance, and 'failover' (automatic or manual) when the Primary is unavailable due to a failure. Shops with Oracle databases are probably familiar with this distinction. Reference: Introduction to Oracle Data Guard - Role Transitions (talk) 18:23, 15 February 2011 (UTC)

Nittin Choudhary[edit]

Who is this Nittin Choudhary person? The contribution that added him as a "renowned OCA" (seriously??? Oracle Certified Associate???) all looks highly suspect to me. (talk) 18:02, 2 November 2012 (UTC) Huw Roberts

More specific name[edit]

I'd like to suggest renaming this article to "Failover (computing)" in order to not confuse it with other types of failovers such as mechanical failovers (which would be more related to Redundancy (engineering)) BDBJack (talk) 22:03, 16 June 2014 (UTC)
