What will happen When you run Adpreclone and Adcfgclone

 On Source Machine

When you run “adpreclone.pl dbTier” on DB side
  • It will create following directories in the ORACLE_HOME/appsutil/cloneJlib, db, data where “Jlib” relates to libraries “db” will contain the techstack information, “data” will contain the information related to datafiles and required for cloning.
  • Creates driver files at ORACLE_HOME/appsutil/driver/instconf.drv
  • Converts inventory from binary to xml, the xml file is located at $ORACLE_HOME/appsutil/clone/context/db/Sid_context.xml
  • Prepare database for cloning:  This includes creating database control file script and datafile location information file at
  • $ORACLE_HOME/appsutil/templateadcrdbclone.sql, dbfinfo.lst
  • Generates database creation driver file at ORACLE_HOME/appsutil/clone/data/driverdata.drv
  • Copy JDBC Libraries at ORACLE_HOME/appsutil/clone/jlib/classes12.jar and appsutil
When you run “adpreclone.pl appsTier” On Apps Side
  • This will create stage directory at $COMMON_TOP/clone. This also run in two steps.
  • Techstack:  Creates template files for Oracle_iAS_Home/appsutil/template and Oracle_806_Home/appsutil/template
  • Creates Techstack driver files for IAS_ORACLE_HOME/appsutil/driver/instconf.drv and 806_ORACLE_HOME/appsutil/driver/instconf.drv
  • APPL_TOP preparation:  It will create application top driver file at $COMMON_TOP/clone/appl/driver/appl.drv-Copy JDBC libraries and $COMMON_TOP/clone/jlib/classes111.zip
  • Now Shutdown all the services of Application and database to Copy the file System to target location.

On Target Machine

Run adcfgclone.pl for dbTier.
On database node
  • cd $ORACLE_HOME/appsutils/clone/bin
  • perl adcfgclone.pl dbTier pwd=apps
  • This will use the templates and driver files those were created while running adpreclone.pl on source system and has been copied to target system.
  • Following scripts are run by adcfgclone.pl dbTier for configuring techstack
  • adchkutl.sh — This will check the system for ld, ar, cc, and make versions.
  • adclonectx.pl — This will clone the context file. This will ceate a new context file as per the details of this instance.
  • runInstallConfigDriver — located in $Oracle_Home/appsutil/driver/instconf.drv
  • Relinking $Oracle_Home/appsutil/install/adlnkoh.sh — This will relink ORACLE_HOME
  • For data on database side, following scripts are runDriver file $Oracle_Home/appsutil/clone/context/data/driver/data.drv
  • Create database adcrdb.zipAutoconfig is runControl file creation adcrdbclone.sql
  • Run adcfgclone.pl for dbTier.
On Application Side
  • cd $COMMON_TOP/clone/bin/
  • perl adcfgclone.pl appsTier pwd=apps
  • Following scripts are run by adcfgclone.pl:
  • Creates context file for target adclonectx.pl
  • Run driver files $ORACLE_HOME/appsutil/driver/instconf.drv and $IAS_ORACLE_HOME/appsutil/driver/instconf.drv
  • Relinking of Oracle Home $ORACLE_HOME/bin/adlnk806.sh and $IAS_ORACLE_HOME/bin/adlnkiAS.sh
  • At the end it will run the driver file $COMMON_TOP/clone/appl/driver/appl.drv and then runs autoconfig.

  1. Thank you for a good article. It’s better to read it than to finding and reviewing adpreclone and adcfgclone log files:)
