migration guideCross Endian Platform Migration using XTTSv4 + FTEX
Introduction​
This guide shows how to use the perl XTTSv4 script to migrate a database cross platform/endian with transportable tablespace and RMAN incremental backups for minimal downtime.
For the migration of the metadata Data Pump Full Transportable Export Import (FTEX) is used.
Objectives​
In this guide we will cover the following objectives in detail:
- Cross Platform/Endian Migration
- Migration to higher database release
- Migration from non-CDB to PDB
- Convert single instance to RAC
- Minimal Downtime
- Encrypt tablespaces in the target database
Prerequisites​
- Oracle 11.2.0.4 source database running on SPARC Solaris
- Oracle 19c CDB instance running on Exadata Cloud@Customer
- PDB target database setup
- Shared NFS storage mounted on source and target systems
Requirements​
COMPATIBLEparameter equal or higher on the target- Identical database character set
- Identical national character set
- Same or higher time zone version
- Identical database time zone setting
- TIMESTAMP WITH LOCAL TIME ZONE columns
- Oracle software owner has read/write permission on the NFS share
- NFS Storage: Free disk space to store level 0 + all incremental backups
Restrictions​
- No migration to Autonomous Database
- TDE encrypted source database
- No support for windows (source or target)
- Transportable Tablespace (TTS) Restrictions and Limitations: Details, Reference, and Version Where Applicable (Doc ID 1454872.1)
Environment Setup​
Overview​
The following table outlines the key components of our demo environment used in this guide. Please note the color code for the source and target environment. All the code elements shown in the guide are marked with a colored left border to indicate on which environment the code needs to be run.
SOURCE | TARGET | |
|---|---|---|
| Platform | Oracle SPARC | Exadata C@C |
| Operating System | Solaris 11.4 | Oracle Linux 8 |
| DB Version | 11.2.0.4 | 19.22 |
| Multitenant | non-CDB | PDB |
| High Availability | Single Instance | 2 node RAC |
| Disaster Recovery | - | - |
| Storage Location | ASM | ASM |
| DB Name | SRC11G | TGT19C |
| PDB | - | TGTPDB |
The following table lists different parameters and settings for the source and target database. The Gather Database Info in the source and target database chapter shows in detail how to gather the information:
SRC11G | TGTPDB | |
|---|---|---|
| Platform ID | 2 | 13 |
| Tablespaces | USERS,EXAMPLE,TEST,SOE | |
| Timezone File Version | 14 | 42 |
| DB Timezone | +00:00 | -07:00 |
| Characterset | WE8MSWIN1252 | WE8MSWIN1252 |
| National Characterset | AL16UTF16 | AL16UTF16 |
| TDE Encryption | No | Yes |
We need to have the same DB timezone on the source and target especially if TIMESTAMP WITH LOCAL TIME ZONE columns are used. The Change dbtimezone section shows how to change the timezone on the target to match the source database value.

Enable Block Change Tracking​
info
Block Change Tracking is not available in Standard Edition 2 and Oracle Base Database Service Standard Edition.
Features and Licensing Information
To speed up the incremental backups we enable block change tracking on the source database.
Enable (use default file and location):
alter database enable block change tracking;As an alternative you can also specify a file that will be used:
ALTER DATABASE ENABLE BLOCK CHANGE TRACKING USING FILE '/<path>/bct.ora';Check status if block change tracking is enabled

-07:00We have a different dbtimezone setting compared to the source database. We will change this in Change dbtimezone.
Check character set:

SQL> select property_name, property_value from database_properties where property_name in ('NLS_CHARACTERSET', 'NLS_NCHAR_CHARACTERSET') order by 1;PROPERTY_NAME PROPERTY_VALUE
------------------------- -------------------------
NLS_CHARACTERSET AL32UTF8

------------------------- -------------------------
NLS_CHARACTERSET WE8MSWIN1252
NLS_NCHAR_CHARACTERSET AL16UTF16noteIn the above output we are using a different characterset in the PDB compared to the character set of the CDB (AL32UTF8). In general Oracle recommends to use AL32UTF8 as the character set for the CDB. It's possible to create PDBs with different character sets in the CDB.
Install Data Pump Bundle Patch​
- Make sure install the latest Data Pump Bundle Patch on the target:
Change dbtimezone​
Change dbtimezone to match source database:
alter database set time_zone='+00:00';noteAfter updating the dbtimezone, ensure you restart the PDB. This step is important for the changes to become effective.
Shared NFS​
Create a directory on the NFS share to hold the backup of the source database. The directory needs to be read/writeable for the
oracleuser on the source and target.mkdir -p /nfsbackup/xtt
chmod 777 /nfsbackup/xtt
Perl Scripts​
Download
rman_xttconvert_VER4.3.zipfrom Doc ID 2471245.1Install
rman_xttconvert_VER4.3.zipscript on the source asoraclesoftware owner:Create a new directory for the xtts scripts:
mkdir $HOME/xttCopy the file into $HOME/xtt:
cp -p rman_xttconvert_VER4.3.zip $HOME/xttUnzip the file:
cd $HOME/xtt
unzip rman_xttconvert_VER4.3.zipArchive: rman_xttconvert_VER4.3.zip

inflating: xttcnvrtbkupdest.sql
inflating: xttdbopen.sql
inflating: xttdriver.pl
inflating: xttprep.tmpl
extracting: xttstartupnomount.sql
Migration​
1. Edit xtt.properties​
- Modify the xtt.properties file on the source:
At a minimum the following parameters need to be set. There are some other parameters which are described in the properties file.
cat xtt.properties | egrep -v '^#|^$'
#mandatory parameters
tablespaces=EXAMPLE,TEST,USERS,SOE
platformid=2
src_scratch_location=/nfsbackup/xtt
dest_datafile_location=+DATAC2
dest_scratch_location=/nfsbackup/xtt
#optional parameters
parallel=4
rollparallel=2
getfileparallel=4
info
usermantransport=1 should be set if the source db is 12c or higher and should be never set different between the source and destination.
2. Copy files to target​
Create directory on target server:
mkdir -p $HOME/xtt
cd $HOME/xttCopy the file with
scpto the target:scp -rp $HOME/xtt oracle@dest:/home/oracle/xtt
If there is no scp connection between the server you can also use the shared nfs storage for sharing files between the servers. We will use this approach in this guide:
Create a directory to share the files under xtt on the nfs share and copy the files to that directory:
mkdir -p /nfsbackup/xtt/copy
cp -rp $HOME/xtt /nfsbackup/xtt/copy/On the target copy the files from the shared directory to the local directory on
$HOME:# on target
cp -p /nfsbackup/xtt/copy/xtt/* $HOME/xtt
ls -la $HOME/xtt
3. Start backup on source​
note
Before you run any xtt perl command make always sure that TMPDIR is set. In this guide we will export TMPDIR before every command. Additionally make sure that ORACLE_HOME and ORACLE_SID are set correctly.
export TMPDIR=$HOME/xtt
info
You can enable additional debug information by setting the XTTDEBUG=1 environment variable before running the xttdriver.pl script or adding the --debug [1/2/3] flag to the command. (Level 3 generates the most information)
cd $HOME/xtt
export TMPDIR=$HOME/xtt
nohup $ORACLE_HOME/perl/bin/perl xttdriver.pl --backup --debug 3 > lev0.out 2>&1 &

Logfile is written to $TMPDIR/backup_[timestamp]/[timestamp].log
After the first backup the perl script created the res.txt file and added information to it:
cat res.txt
#0:::4,2,USERS_4.dbf,0,4455484,0,0,0,USERS,USERS_4.dbf
#0:::5,2,EXAMPLE_5.dbf,0,4455484,0,0,0,EXAMPLE,EXAMPLE_5.dbf
#0:::6,2,TEST_6.dbf,0,4455484,0,0,0,TEST,TEST_6.dbf
#0:::7,2,SOE_7.dbf,0,4455484,0,0,0,SOE,SOE_7.dbf
We need to transfer the res.txt file to the target system.
For this we will use the directory to share files on the NFS storage we created earlier. As an alternative you can also copy the file via scp to the dest_scratch_location on the target system.
Copy the file via the nfs share:
#on source:
cp -p $HOME/xtt/res.txt /nfsbackup/xtt/copy/# on target:
cp -p /nfsbackup/xtt/copy/res.txt $HOME/xttAlternative with scp: Copy over the
$TMPDIR/res.txtfile to the target server$TMPDIRscp -p $HOME/xtt/res.txt oracle@dest:$HOME/xtt
4. Restore on the target​
note
Again make sure that TMPDIR is set. In this guide we will export TMPDIR before every command. Additionally make sure that ORACLE_HOME and ORACLE_SID are set correctly.
cd $HOME/xtt
export TMPDIR=$HOME/xtt
nohup $ORACLE_HOME/perl/bin/perl xttdriver.pl --restore --debug 3 >lev0.out 2>&1 &

We can now login on the target with asm to check the datafiles. At this point the datafiles have only been restored to the ASM directory. They are currently not attached to the database.

We see the 4 files have been created directly under DATAC2. But this is just a link to the datafiles that are stored under the actual DB directory. In that case it's the CDB directory. We will fix this at a later step.

5. Roll Forward​
In this phase we will create multiple incremental backups to update the target database.
5.1. Level1 Backup​
We start another backup on the source db:
cd $HOME/xtt
export TMPDIR=$HOME/xtt
nohup $ORACLE_HOME/perl/bin/perl xttdriver.pl --backup --debug 3 > roll1.out 2>&1 &

Again we need to transfer the file to the target system:
# on source:
cp -p $HOME/xtt/res.txt /nfsbackup/xtt/copy/
# on target:
cp -p /nfsbackup/xtt/copy/res.txt $HOME/xtt
caution
The following restore restarts the current instance into nomount mode!
This is especially relevant if there are multiple PDBS running in the target CDB.
5.2. Level1 Restore​
We restore the level1 backup on the target system:
```bash className=code-tgt
cd $HOME/xtt
export TMPDIR=$HOME/xtt
nohup $ORACLE_HOME/perl/bin/perl xttdriver.pl --restore --debug 3 >roll1.out 2>&1 &
```

We can repeat this phase as often as desired.
Let's create a table and add some rows on the source:
SQL> create user macsdata identified by WELcome##1234 default tablespace example temporary tablespace temp quota unlimited on example;
SQL> create table macsdata.mactab1 (id number, name varchar(50));
SQL> insert into macsdata.mactab1 values (1,'MACS');
1 row created.
SQL> insert into macsdata.mactab1 values (2,'DATA');
1 row created.
SQL> commit;
Commit complete.
5.3. Level1 Backup​
Now create another Level 1 backup
cd $HOME/xtt
export TMPDIR=$HOME/xtt
nohup $ORACLE_HOME/perl/bin/perl xttdriver.pl --backup --debug 3 >roll2.out 2>&1 &
cp -p $HOME/xtt/res.txt /nfsbackup/XTT/copy/

Again we need to transfer the file to the target system:
# on source:
cp -p $HOME/xtt/res.txt /nfsbackup/xtt/copy/
# on target:
cp -p /nfsbackup/xtt/copy/res.txt $HOME/xtt
5.4. Level1 Restore​
Again we restore the level1 backup on the target system:
cd $HOME/xtt
export TMPDIR=$HOME/xtt
nohup $ORACLE_HOME/perl/bin/perl xttdriver.pl --restore --debug 3 >roll2.out 2>&1 &

7. Import Metadata​
To import the metadata we use Data Pump Full Transportable Export Import (FTEX).
Gather dictionary stats on the source and target to make sure the export runs performant:
exec dbms_stats.gather_schema_stats('SYS');
exec dbms_stats.gather_schema_stats('SYSTEM');
exec dbms_stats.gather_dictionary_stats;
exec dbms_stats.gather_fixed_objects_stats;exec dbms_stats.gather_schema_stats('SYS');
exec dbms_stats.gather_schema_stats('SYSTEM');
exec dbms_stats.gather_dictionary_stats;
exec dbms_stats.gather_fixed_objects_stats;Set
streams_pool_sizeon both databases:alter system set streams_pool_size=256m scope=both;alter system set streams_pool_size=256m scope=both;Create a Data Pump directory on the target PDB:
mkdir -p /nfsbackup/xtt/dp
chmod -R 777 /nfsbackup/xtt/dp/export ORACLE_PDB_SID=TGTPDB
sqlplus "/ as sysdba"
show pdbs;
create directory dpxtt as '/nfsbackup/xtt/dp';
GRANT READ, WRITE ON DIRECTORY dpxtt TO system;Generate
transport_datafilesparameter:Execute the following on the source database. This will generate a data pump command in the
xttplugin.txtfile. We are interested in thetransport_datafiles line:cd $HOME/xtt
export TMPDIR=$HOME/xtt
$ORACLE_HOME/perl/bin/perl xttdriver.pl -ecat xttplugin.txt
impdp directory=<DATA_PUMP_DIR> logfile=<tts_imp.log> \
network_link=<ttslink> transport_full_check=no \
transport_tablespaces=EXAMPLE,TEST,USERS,SOE \
transport_datafiles='+DATAC2/USERS_4.dbf','+DATAC2/EXAMPLE_5.dbf','+DATAC2/TEST_6.dbf','+DATAC2/SOE_7.dbf'
There are 2 options to import the metadata.
In the first example we will use a db link and run the import over sqlnet.
Option 1: DB Link​
Create DB Link
export ORACLE_PDB_SID=TGTPDB
sqlplus "/ as sysdba"SQL> create public database link xttlink connect to system identified by welcome1 using '//host:1521/SRC11G';Test DB Link:
SQL> select name from v$database@xttlink;NAME
---------
SRC11GCreate import par file:
$ cd /nfsbackup/xtt/dp
$ vi imp.parAdd the following parameters. The transport_datafiles parameter you can copy from the xttplugin.txt file from the source we created earlier. The 2 most important parameters are
FULL=yandTRANSPORTABLE=always. These 2 parameters initiate a Full Transportable Export Import operation.FULL=y
TRANSPORTABLE=always

LOGFILE=xttimp.log
METRICS=y
LOGTIME=all # only available in 12g
VERSION=12.0 # needs to be specified if the source database compatible init.ora parameter is not set to a value of at least 12.0Run the imp.sh script:
cd /nfsbackup/xtt/dp
export ORACLE_PDB_SID=TGTPDB

Option 2: Export / Import​
In case we don't have direct access from the target to the source to create the database link we can also run the export and import operation in 2 separate steps:
Create directory
We also need to create a directory on the source:
sqlplus "/ as sysdba"
create directory dpxtt as '/nfsbackup/xtt/dp';
GRANT READ, WRITE ON DIRECTORY dpxtt TO system;Create parameter files:
$ cd /nfsbackup/xtt/dp
$ vi exp.parFULL=y
TRANSPORTABLE=always
PARALLEL=2 # only for 21c and above
EXCLUDE=TABLE_STATISTICS,INDEX_STATISTICS
EXCLUDE=SYS_USER # SYS_USER should be excluded as best practice for import in PDB
EXCLUDE=TABLESPACE:"IN('TEMP')"
DIRECTORY=xttdir
LOGFILE=xttexp.log
METRICS=y
#LOGTIME=all # only available in 12g
VERSION=12.0 # needs to be specified if the source database compatible init.ora parameter is not set to a value of at least 12.0Next create import parameter file:
vi imp.partransport_datafiles='+DATAC2/USERS_4.dbf','+DATAC2/EXAMPLE_5.dbf','+DATAC2/TEST_6.dbf','+DATAC2/SOE_7.dbf'
PARALLEL=2 # only for 21c and above
EXCLUDE=SCHEMA:"IN('WMSYS','ORDDATA','SYSTEM','SYS')"
EXCLUDE=SCHEMA:"IN('SPATIAL_CSW_ADMIN_USR','SPATIAL_WFS_ADMIN_USR')" # exclude spatial users - removed in 19c
DIRECTORY=xttdir
LOGFILE=xttimp.log
METRICS=y
LOGTIME=allRun the export on the source:
cd /nfsbackup/xtt/dp
nohup expdp system/welcome1 parfile=exp.par >exp.out 2>&1 &Check for errors:
grep -i ORA- xttexp.logRun the import on the target:
cd /nfsbackup/xtt/dp
export ORACLE_PDB_SID=TGTPDB
nohup impdp system/WELcome##1234 parfile=imp.par >imp.out 2>&1 &Check for errors:

9. Encryption​
Let's check the tablespace encryption. After the restore from the unencrypted source the tablespaces are also unencrypted on the target:
select tablespace_name, status, encrypted from dba_tablespaces;TABLESPACE_NAME STATUS ENC

SYSTEM ONLINE YES
SYSAUX ONLINE YES
UNDOTBS1 ONLINE YES
TEMP ONLINE YES
UNDO_2 ONLINE YES
USERS ONLINE NO
EXAMPLE ONLINE NO
SOE ONLINE NO
TEST ONLINE NOTo get more information also the following view can be used:
select * from V$ENCRYPTED_TABLESPACES;Encrypt the tablespaces. This is an online operation:
-- Default AES128
-- encryption algorythm can also be specified
-- alter tablespace example encryption online using 'AES128' encrypt;
alter tablespace example encryption online encrypt;
alter tablespace soe encryption online encrypt;
alter tablespace test encryption online encrypt;
alter tablespace users encryption online encrypt;Check again the tablespace encryption status:
select tablespace_name, status, encrypted from dba_tablespaces;TABLESPACE_NAME STATUS ENC

10. Post Tasks​
The following tasks should be executed after the migration:
- Gather statistics on the target
- Dictionary
- Table
- Backup
Optional restart PDB and check violations:
alter pluggable database TGTPDB close immediate instances=all;
alter pluggable database TGTPDB open instances=all;
select name, type, status, cause, message, action from PDB_PLUG_IN_VIOLATIONS where status != 'RESOLVED';Optional change tablespaces back to read write on the source:
alter tablespace TEST read write;
alter tablespace EXAMPLE read write;
alter tablespace SOE read write;
alter tablespace USERS read write;
11. Cleanup​
- Drop the $HOME/xtt directories
- Remove the Files and NFS Share
Drop the public database link in the target db
drop public database link xttlink;
Troubleshooting​
Known Issues for Cross Platform Transportable Tablespaces XTTS (Doc ID 2311677.1)
ERROR IN CONVERSION ORA-19624: operation failed, retry possible CONVERTED BACKUP PIECE/nfsbackup/XTT/xib_622or76s_1_1_7
Solution: Make sure the directory is writeable for the oracle user on the target /nfsbackup/XTT directory
Conclusion​
In this guide we used the XTTSv4 perl scripts to successfully migrate a database across different platform/endian from SPARC Solaris to Exadata Cloud@Customer.
