Duplicate database in ODA (Source and Target database going to be under the same server)


For this duplicate database testing in ODA , we are going to use source database as MANGO db and duplicate database name as clonedb.

1. Preparation

1.1 gather source database information.

First gather MANGO database details such as
  1. datafile location.
  2. number of redo log files.
  3. db recovery file desk.

Check datafile location:


set lines 800
col file_name for a100
select file_name,bytes/1024/1024 MB ,maxbytes/1024/1024 MB from dba_data_files;

FILE_NAME                                                                                                    MB         MB

check for redo file locations :

1.2 Backup source database. 

 We need to take backup of source database. If the schedule backup are not there use below mention run block to take a source database backup.

############## Backup source database

RUN
{
  ALLOCATE CHANNEL ch1 TYPE DISK MAXPIECESIZE 5G;
  ALLOCATE CHANNEL ch2 TYPE DISK MAXPIECESIZE 5G;
  BACKUP 
  FORMAT '/db_backup/MANGO_BKP/%d_D_%T_%u_s%s_p%p'
  DATABASE
  CURRENT CONTROLFILE 
  FORMAT '/db_backup/MANGO_BKP/%d_C_%T_%u' 
  SPFILE

  PLUS ARCHIVELOG 
  FORMAT '/db_backup/MANGO_BKP/%d_A_%T_%u_s%s_p%p'; 
  RELEASE CHANNEL ch2;
}
If you want to take separate archivelog backup use below run block.

############### archive backup 

run 
{
