Full Transportable Export/Import – PAR File Examples

Roy and I blogged about Full Transportable Export/Import in the past:

• Full Transportable Export/Import White Paper
• Full Transportable Export/Import – Things to Know
• Full Transportable Export/Import – Migrating an 11.2.0.4 database to Oracle Database 12c- into the Oracle Cloud
• Exclude Stats differently for TTS and FTEX

If you haven’t heard of this database feature, it allows you to migrate a full database by using Transportable Tablespaces as a base technology but letting Data Pump do all the manual steps for you in a one-command migration. And if needed, it works with RMAN Incremental Backups as well in order to decrease the downtime for copying larger databases. It works cross-platform, cross-Endianness – and as early as with a source version of Oracle Database 11.2.0.3 – but only towards Oracle Database 12c.

Often there are questions regarding the correct syntax for the parameter files. As I have to look it up from time to time as well I thought I’d share some example par files as there are two different approaches: With or without NETWORK_LINK.

With expdp/impdp – without NETWORK_LINK

expdp.par

directory=oradump
dumpfile=wspmst_ftex_exp.dmp
logfile=wspmst_ftex_exp.log
transportable=always
full=y
metrics=y
logtime=all
parallel=8
exclude=table_statistics,index_statistics

impdp.par

directory=oradump
dumpfile=wspmst_ftex_exp.dmp
logfile=wspmst_ftex_imp.log
metrics=y
logtime=all
parallel=8
TRANSPORT_DATAFILES='/oradata/wspmst/data/WSPMSTCON/3ABC7F153DB55A4DE0539ED0C80A102D/datafile/advsecmon.331.880913493'
TRANSPORT_DATAFILES='/oradata/wspmst/data/WSPMSTCON/3ABC7F153DB55A4DE0539ED0C80A102D/datafile/advsecmon.555.880923697'

Only impdp (no expdp) – using NETWORK_LINK

2 examples here – one dealing with an Oracle 11.2 source database, the other moving directly from Oracle 12c non-CDB into a pluggable database (PDB).

impdp1.par

impdp mike/passwd@v121
NETWORK_LINK=v112

FULL=Y
TRANSPORTABLE=ALWAYS
VERSION=12
METRICS=Y
exclude=table_statistics,index_statistics

LOGTIME=ALL
LOGFILE=ftex_dir:v112fullimp.log
TRANSPORT_DATAFILES='/oracle/DQ1/sapdata50/ts1.dbf'
TRANSPORT_DATAFILES='/oracle/DQ1/sapdata50/ts2.dbf'

impdp2.par

impdp system/oracle@pdb2
network_link=sourcedb
full=y
transportable=always
metrics=y
exclude=table_statistics,index_statistics
directory=mydir logfile=pdb2.log
transport_datafiles='/u02/oradata/CDB2/pdb2/users01.dbf'
transport_datafiles='/u02/oradata/CDB2/pdb2/users02.dbf'
transport_datafiles='/u02/oradata/CDB2/pdb2/users03.dbf'

Please note:

• The VERSION=12 option must be used only when an Oracle 11.2 database is the source as in this case Data Pump on the 11.2 side must be triggered to access this 12c feature and create an export in a form the 12c Data Pump can understand.
• There’s no expdp necessary when using Data Pump over a database link (NETWORK_LINK). But in this case you will need the keywords FULL=Y and TRANSPORTABLE=ALWAYS as export parameters as the export portion of Data Pump on the source side will be triggered underneath the covers.
