It is confusing that two-phase locking links to strict, while 2PL to non-strict. I think 2PL should refer to the strict version. -- User:clausen

The statement that 2PL may fix the deadlock situation is (probably) incorrect, since both 2PL and S2PL go through the same growing phase.

And in English... ?![edit]

What on earth does this all mean? I can't make head nor tail of it. - Ta bu shi da yu 06:39, 2 August 2005 (UTC)

Think there is a syntaxis error[edit]

T1: S(A), R(A); T2: S(A), R(A), X(B), R(B), W(B), Commit; T1: X(C), R(C), W(C)... The last C should be a B

and teh same error in the image

Merge proposal[edit]

Please see previous discussion at Talk:Non-strict two-phase locking but reply below. - Fayenatic london (talk) 18:43, 26 June 2007 (UTC)

The article contains NO any valuable material. Maybe I used a too polite language. It is a disgrace to Wikipedia, and should be removed. The proposed merger is REJECTED. 2PL will get a proper article. Please delete or return the deletion tag. Comps 01:35, 27 June 2007 (UTC)

The previous comment is regarding the article Non-Strict Comps 01:38, 27 June 2007 (UTC)

I see the reason for removal was gone with the removal tag:

The name of the article is for the set Complement(S2PL) which does not make a sense for an article. It actually describes the set 2PL-S2PL which does not make sense as an article either. You'll find no articles or book chapters on these sets since it does not make any sense. 2PL needs an article. If putting a deletion tag has violated any Wikipedia regulation please advise. Comps 02:05, 27 June 2007 (UTC)

A merge tag has appeared, now with 2PL. I oppose a merge, and again recommend a deletion of this article, and removal of this tag, which has been added without information added to the old discussion. See also Talk:Two-phase locking. -- Comps (talk) 12:20, 16 June 2009 (UTC)


This article is incomplete and inconsistent with the 2pl page. This page only describes strong strict 2pl as 2. All locks held by transaction T are released when T commits (and not before). does not apply to "normal" strict 2pl, since shared locks are released earlier in that case. --LKRaider (talk) 17:35, 24 November 2008 (UTC)

Redirect to Two-phase locking[edit]

I redirected this article to Two-phase locking. Plase, continue any discussion on that article's talk page. Svick (talk) 18:27, 19 August 2009 (UTC)
