Bug 1086849

Title: About the LRCO Optimization for Single-phase Commit (1PC)

In Section 10.3.2 it describes only old LRCO Optimization mechanism.
But it needs new section about Commit Markable Resource (new implementation of LRCO algorithm) algorithm description as well.


Original bug from which it is cloned is about adding new section about the same new CMR algorithm in Administration and Configuration Guide.

+++ This bug was initially created as a clone of Bug #1073834 +++

Hi,

in EAP 6.3.0 transaction team implemented new feature as documented here:
https://issues.jboss.org/browse/PRODMGT-49

It's new implementation of LRCO algorithm which makes non-xa resource fully recoverable (if it's database datasource and as it's just one in the XA transaction).

It's necessary to document this new feature. Good person to contact is Tom Jenkinson <tom.jenkinson>.

Please, then document that this new datasource needs to have new argument "connectable" set to true. It would be probably fine to add this thing under the section about configuraton of XA and non-XA datasources (like http://documentation-devel.engineering.redhat.com/site/documentation/en-US/JBoss_Enterprise_Application_Platform/6.3/html-single/Administration_and_Configuration_Guide/index.html#Configure_an_XA_Datasource)

Thank you
Ondra
