Running AutoConfig in Parallel in EBS 12

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:

Executing AutoConfig in Parallel Mode

The following command can be used to run AutoConfig in 'parallel mode'

Application Tier

perl $AD_TOP/bin/adconfig.pl contextfile=<CtxFile> [product=<product_top>] –parallel

Database Tier

perl $ORACLE_HOME/appssutil/bin/adconfig.pl contextfile=<CtxFile> –parallel

where

<CtxFile> is the absolute path to the context file
<product_top> is the Product short name

Note that while running AutoConfig simultaneously on multiple nodes, it is very important to ensure that the '-parallel' option is specified while starting AutoConfig on each node to prevent unstable and/or inconsistent filesystem and database states.
