====== Cloning a PDB between servers using NFS share ======


  * Create a Copy of Source PDB

<code PLSQL>
# Set Oracle environment
. oraenv <<< CDB1

# Connect to SQL*Plus
sqlplus / as sysdba

# Check current PDBs
show pdbs

# Create PDB copy
create pluggable database PDB2_COPY from PDB2;

# Verify creation
show pdbs
exit
</code>

  *  Move PDB to NFS Share
<code PLSQL>
# Set Oracle environment
. oraenv <<< SITNECDB

# Connect to SQL*Plus
sqlplus / as sysdba

# Close the PDB
Alter pluggable database SIT_PDB2_COPY close immediate instances=all;

exit

rman target /

run {
    allocate channel c1 type disk;
    allocate channel c2 type disk;
    allocate channel c3 type disk;
    allocate channel c4 type disk; 
    backup as copy pluggable database SIT_PDB2_COPY format '/NFS/ORACLE/pdb_copy/%U';
}

switch pluggable database SIT_PDB2_COPY to copy;
exit
</code>

  *  Create Manifest File
<code PLSQL>
sqlplus / as sysdba

alter pluggable database SIT_PDB2_COPY unplug into '/NFS/ORACLE/pdb_copy/SIT_PDB2_COPY.xml';

show pdbs
exit
</code>

  * Create PDB on Target Server
<code PLSQL>
# Set Oracle environment
. oraenv <<< SITNECDB

sqlplus / as sysdba

create pluggable database PDB2 using '/NFS/ORACLE/pdb_copy/SIT_PDB2_COPY.xml';
exit
</code>

  * Restore PDB datafiles on Target Server
<code PLSQL>
rman target /

run {
    allocate channel c1 type disk;
    allocate channel c2 type disk;
    allocate channel c3 type disk;
    allocate channel c4 type disk; 
    backup as copy pluggable database PDB2 format '+DATA';
}
 
switch pluggable database PDB2 to copy;
exit
</code>

  *  Clean Up Source CDB 
<code PLSQL>
# Drop the PDB copy
drop pluggable database PDB2_COPY including datafiles;

# Verify PDBs
show pdbs
exit
</code>

  *  Clean Up  data files on the NFS
<code BASH>
# Remove the datafiles on the NFS
cd /NFS/ORACLE

rm -rf /NFS/ORACLE/pdb_copy
