Cold Backup Cloning
Assumptions:
1) Target database is similar in configuration to source database.
2) oratest and appltest users are created in the target database under dba group.
3) Environment is always set when logged in as oracle or applmgr in source system.
Pre Cloning Steps:
1) DB Tier is precloned first. Ex: cd $ORACLE_HOME/appsutil/scripts/SID/ perl adpreclone.pl dbTier
2) Apps Tier to be precloned next. Ex: cd $COMMON_TOP/admin/scripts/SID/ perl adpreclone.pl appsTier
Cold Backup:
1) Shutdown Application, Listener and Database. Verify if they are down.
$ ps -ef|grep applprod
applprod 10031 1471 0 18:24:46 pts/ta 0:00 ps -ef
applprod 10032 1471 1 18:24:46 pts/ta 0:00 grep applprod
applprod 1471 29301 0 18:06:07 pts/ta 0:00 –sh
$ ps -ef|grep tns
applprod 10105 1471 0 18:25:41 pts/ta 0:00 grep tns
$ ps -ef|grep oraprod
applprod 10107 1471 0 18:25:46 pts/ta 0:00 grep oraprod
oraprod 29760 29518 0 17:48:26 pts/tb 0:00 -sh
2) Copy APPL_TOP, COMMON_TOP and ORA_TOP from applmgr and move it to Target system under appltest directory.
Ex : scp –r <filename> root@<ipaddress>:<location>
3) Copy DATA_TOP and DB_TOP from oracle and move it to Target System under oratest directory.
Ex : scp –r <filename> root@<ipaddress>:<location>
4) Now change the ownerships of the moved files in the target system accordingly.
Ex: chown –R appltest:dba <filename>
chown –R oratest:dba <filename>
Post Cloning Steps:
1) DB Tier is configured first. Ex: cd $ORACLE_HOME/appsutil/clone/bin Perl adcfgclone.pl dbTier.
2) Enter apps password and all other relevant information.
3) The database is started.
4) Apps Tier is configured next. Ex: cd $COMMON_TOP/clone/bin perl adcfgclone.pl appsTier
5) Enter apps password and all other relevant information accordingly.
6) After it is completed, it prompts whether to start Applications or not.
Log Files :
1) cd $ORACLE_HOME/appsutil/log/CONTEXT NAME/*.log
2) cd $APPPL_TOP/admin/CONTEXT NAME/log/*.log or
cd /u01/inst/apps/PROD_ashirwad/admin/log/StageAppsTier_11021810.log(R12)
Note: If u want to take backup use commands
tar -cvf filename.tar <directoryname> ß creates
tar -xvf filename.tar <directoryname> ß reads
tar –C <location> -xvf filename.tar ß untars at a particular location
