– Full Transportable Export-Import

Example:Full Transportable Tablespace expdmp/impdmp

New Full Transportable Tablespace


• Application Data?• Tablespaces – Read only mode

Environments:

Source Database 11.2.0.4 IBM: Linux on System z

TBSpace Name Datafile Name

HR_1 /u01/app/oracle/oradata/hr_db/hr_101.dbf




Target Database 12.1.0.1 IBM: Linux on System z

Target � ORACLE_SID HR_PDB

Datafiles � /u01/app/oracle/oradata/hr_pdb/

Checks and Setup on Source

Ensure no logical or physical dependencies between objects in different tablespaces which are NOT being transported.:

– Containment check as follows:-

SQL> EXECUTE DBMS_TTS.TRANSPORT_SET_CHECK('hr_1,hr_2', TRUE);

– Check for violations from above as follows:-


SQL> SELECT * FROM TRANSPORT_SET_VIOLATIONS

– Create a directory object in the source DB

SQL> CREATE DIRECTORY dp_dir AS ’/u01/app/datafiles’;

– Place the hr_1 and hr_2 tablespaces in read-only mode for duration of export.

SQL> ALTER TABLESPACE hr_1 READ ONLY;

SQL> ALTER TABLESPACE hr_2 READ ONLY;

Full Transportable Tablespace Migration

� Invoke the Data Pump export utility:

expdp system/manager full=y transportable=always version=12 \

directory=dp_dir dumpfile=full_tts.dmp metrics=y exclude=statistics \

logfile=full_tts_export.log

Note: VERSION=12 because source is 11.2.0.4


Note: VERSION=12 because source is 11.2.0.4

� Check export Log for list of data files to be moved

On Target server copy all datafiles to be moved....

$ cd /u01/app/oracle/oradata/hr_pdb/

$ cp /net/<source-server>/u01/app/oracle/oradata/hr_db/hr_101.dbf .

$ cp /net/<source-server>/u01/app/oracle/oradata/hr_db/hr_102.dbf .

...................


� Create a directory object on the destination database for import:-

SQL> CREATE DIRECTORY dp_dir AS '/u01/app/oracle/oradata/hr_pdb';

SQL> GRANT read, write on directory dp_dir to system;

� Invoke full transportable import on destination PDB database:-


$ impdp system/manager@hr_pdb directory=dp_dir \

dumpfile=full_tts.dmp logfile=full_tts_imp.log metrics=y \

transport_datafiles='/u01/app/oracle/oradata/hr_pdb/hr_101.dbf',\

'/u01/app/oracle/oradata/hr_pdb/hr_102.dbf'

Note: Command line or parameter file can be used

– Check import log file for errors


� On completion of import, tablespaces will be placed in read/write mode on destination PDB.

� Return source database tablespaces to read/write once import has completed:-

SQL> ALTER TABLESPACE hr_1 READ WRITE;




Reference: White Paper.

http://www.oracle.com/technetwork/database/enterprise-edition/full-transportable-wp-12c-1973971.pdf

Note: NFS mount point – 12c impdp requires volume exported with (insecure) option

# cat /etc/exports /nfs *(rw,no_root_squash,insecure)

ORA-39097 – May require Fix for Patch 17583185 (11.2.0.x and 12.1))


Limitations:-

� Tablespaces in read-only mode a problem – RMAN backups can be used.

� Different “endianness”:-

– RMAN CONVERT DATAFILE command to convert the data.

– GET_FILE or PUT_FILE procedures from the DBMS_FILE_TRANSFER package


– No transport of encrypted tablespaces to platform of different endianness

� XDB repository cannot be transported(XML schemas can!)

� AWR repository cannot be transported

– Use the awrextr.sql and awrload.sql scripts to move between source and target dbs

� Source and target databases must use compatible database character sets

Demo

Upgrade 11.2.0.3 -> 12.1.0.1

� Preupgrd.sql

� DBUA

� Plug in upgraded db to 12.1.0.1 Container Database– Database upgrade

– Start database read-only


– Start database read-only

– Create XML description file

» exec dbms_pdb.describe(pdb_descr_file=>'/home/oracle/SIG1unplug.xml');

– Shutdown database

– Plugin database

» create pluggable database PDB3 as clone using '/home/oracle/SIG1unplug.xml';

– Sanity operations

» @?/rdbms/admin/noncdb_to_pdb.sql
