Merged in Two-phase commit

I just merged in the content from Two-phase commit. There was almost 100% overlap in content, though there were differences in terminology and formatting. I hope you all like the result. Jamie 01:12, 14 November 2005 (UTC)[reply]


The following paragraph in "Disadvantages" is incorrect and needs to be removed:

"Another disadvantage is the protocol is conservative. It is biased to the abort case rather than the complete case. Also it cannot recover from cases where a node has failed in the commit stage (due to internal or network failures) after indicating that it is ready to commit. In this case, resources that committed prior to this failure cannot be rolled back."

First, it can be biased either to commit or abort (see literature). Also, all known commercial implementations recover correctly (to abort) if such faliure occures. No resource commits before completion (decision by coordinator)
