adpreclone.pl - This is the preparation phase, will collects information about the source system, creates a cloning stage area, and generates templates and drivers. All of these are to reconfigure the instance on a Target machine. Preclone will do the following: Convert Symbolic links All symbolic links pointing to a static path will be converted into relative paths Create templates Any files under the $ORACLE_HOME that contain system specific information, will be replicated and converted into a template. These templates are placed into the $ORACLE_HOME/appsutil/template directory. Create driver(s) A driver file, relating to these new templates is created called instconf.drv. This contains a list of all the templates and their locations, and the destination configuration files that these templates will create. This driver file is called instconf.drv and is placed into directory $ORACLE_HOME/appsutil/driver Create Stage area A clone stage is created containing the required java code and scripts to reconfigure the instace on the Target machine Rapid Clone stage area: dbTier : $ORACLE_HOME/appsutil/clone appsTier(s) - $COMMON_TOP/clone The stage area(s) consist of the following directories:-   jre used to run the java code on the Target machine.   bin contains the RapidClone scripts that can be run on the Target machine:-

•    adclone.pl is the main cloning script
•    adcfgclone.pl is used to configure the Target system, this calls adclone.pl
•    adclonectx.pl is used to clone a Source XML file manually
•    adaddnode.pl is used to add a new node to the Patch History tables
•    adchkutl.sh checks for existence of require O/S utils, cc, make, ar and ld

  jlib contains all the Rapid Clone java code, jdbc libraries etc   context contains templates used for a Target XML file   data (Database Tier only) contains the driver file, and templates used to generate the control file SQL script   adcrdb.zip contains the template and list of datafiles on the Source   addbhomsrc.xml contains information on the datafile mount points of the Source   appl (Applications Tier only) this is used when merging appltops, i.e Multi-node to Single node cloning Executing adpreclone.pl will create a log file:- Rapid Clone: dbTier : $ORACLE_HOME/appsutil/log/$CONTEXT_NAME/StageDBTier_xxxxxx.log appsTier : $APPL_TOP/admin/$CONTEXT_NAME/log/StageAppsTier_xxxxxx.log Once this adpreclone.pl step has been completed successfully, all the java .class files under the following directories should be identical to those under $JAVA_TOP/oracle : RDBMS $ORACLE_HOME/appsutil/java/oracle RDBMS $ORACLE_HOME/appsutil/clone/jlib/java/oracle $COMMON_TOP/clone/jlib/java/oracle
