Damage Control

[Editor's Note:  This is the second of a series of four articles on new AutoConfig features.  These articles are written by members of our AutoConfig Development team.  This is your opportunity to interact directly with that team with your feedback on this tool.] Our last article discussed ways of tuning your AutoConfig runs via profiling reports that identify bottlenecks during template instantiation.  This article discusses another method of speeding up your AutoConfig runs.  In an R12 E-Business Suite instance, AutoConfig can now be run simultaneously across multiple nodes. This new feature significantly lowers maintenance downtime for multi-node installations. One beta customer of this feature improved the time it takes them to run AutoConfig across their dozen mid tiers by 45%. How Does AutoConfig's Parallel Mode Work? Executing AutoConfig in 'parallel mode' engages a locking mechanism so that processes running on individual nodes are synchronized. This mechanism prevents any conflicting updates to the database or the file system. The following figure illustrates AutoConfig running in parallel across multiple nodes:
