Transportable Tablespace in ASM

Hi all,
I want to move one tablespace from a database to another database using the 10g cross platform transportable tablespace.
My source database is running on Linux 32 bit (Little endian format) and the target database is running on AIX (Big endian format). However both databases use the ASM diskgroup as a storage option.
Do I need to convert the endian format of the source tablespace datafile to transport to the target database?
Thanks,

Because ASM diskgroup consists of one or more raw
partitions or raw devices, I am wondersing if I still
have to convert the endian format of datafiles..Interesting question.
As you said earlier:
- Linux natively uses Little endian
- AIX natively uses Big endian
You imply that perhaps Linux's ASM 'converts' to an 'Oracle neutral-endian' format whenever something is stored in the ASM disk group. Which would make it identical to AIX's ASM format, also 'converted'.
(I use 'convert' in quotes, as one or the other would not need to get switched, if a specific endian form is maintained.)
Worth investigating further. Although I am not sure why Oracle would introduce the overhead of conversion to-and-from every storage call.

  • Stuck with transported tablespace and ASM

    Hi,
    I'm on 10.2.0.5.4 and playing with TTS feature .
    So I've made TTS on source DB 10.2.0.5 via rman tts feature (auxilary instance) , and copied to cloned database with ASM (same os solaris10).
    Now my situation is as follows :
    on target I can see TTS1 tablespace

    I'm not using catalog (connecting as nocatalog) Hmm....
    The files are listed in V$DATAFILE and DBA_DATA_FILES but not in an RMAN REPORT SCHEMA ?
    That's curious. V$DATAFILE and RMAN REPORT SCHEMA would both be reading from the controlfile.
    What was the sequence of actions to transport the tablespace ? Have you tried reconnecting with RMAN ?

  • Standby not in sync because test on primary of transportable tablespace etc

    This environment is new build environment , have not in use yet.
    db version is 11.2.0.3 in linux, both primary/standby are configured in RAC two nodes and storage are in ASM storage.
    primary db had tested by migration data using transportable tablespace methods. So the datafiles imported were put in a local filesystem which I have to switch to ASM afterwards.
    In such way, the standby db got the impression that datafiles should be in local filesystem and it got invalidated.
    Here is the error from standby log:
    ORA-01157: cannot identify/lock data file 4 - see DBWR trace file
    ORA-01110: data file 4: '/stage/index.341.785186191'
    and datafiles names are all in local filesystem in standby: /stage/...../
    However in primary datafile names are all in ASM instance:
    +DAT/prd/datafile/arindex.320.788067609
    How to resolve such situation?
    Thanks

    My steps for transportable tablespaces after scp the datafiles to linux are import the transportable datafiles into the database. and then using rman to copy it to "+DATA' in asm. and then switch dababase to copy.
    Those procedure all worked on primary.
    The standby was built before the transportable tablespace when there are only system, users, tools etc basic tablespaces. it worked and in sync with primary. However everytime the primary tested data migration with the transportable tablespaces, it will not work.
    so what is the right way to perform this migration? how can I made standby in sync with primary and to read the datafiles in ASM storage?
    Is there a way before the RMAN command to transfer the filesystem datafile to ASM, can I copy those local filesystem datafiles to ASM storage ? then do a import transportable datafiles with those on ASM?If you added any datafiles manually then those will be created in standby also as per the settings,
    But here you performing TTS, of course DML/DDLs can be transfered to standby by archive logs, but what about actual datafiles? Here in this case files exist in primary & those files not exist in standby
    AFAIK, you have to perform couple of steps. Once after your complete migration done in primary do as follows. (Do test it)
    1) Complete your migration on primary
    -- Check all data file status and location.
    2) Now Restore standby controlfile & newly migrated tablespaces in standby Database
    -- here you can directly restore to ASM using RMAN, because you are taking backup in primary using RMAN. So RMAN can restore them directly in ASM file system.
    3) Make sure you have all the datafiles where you want and take care no one data file is missing. Crosscheck all tablespace information in primary & standby databases.
    4) Now start *MRP*
    Here is my above plan, But I suggest to test it...
    One question, After *successful migration* are you able to SYNC standby with primary earlier ?

  • Oracle 10gR2 - Any way to speed up Transportable Tablespace Import?

    I have a nightly process that uses expdp/impdp with Transportable Tablespace option to copy a full schema from one database to another. This process was initially done with just expdp/impdp, however the creation of the indexes started to slow down the process at which time I switched to using Transportable Tablespace.
    In the last 3 months, the number of objects in the schema has not changes however the amount of data has increased 15.73%. At the same time, the Transportable Tablespace impdp has increased 30.77% in time to process.
    Is there any way to speed up a Transportable Tablespace impdp in Oracle 10gR2? The docs show that I cannot use parallel with TTS. I have excluded STATISTICS in the export.
    Eventually I will be moving away from doing this TTS expdp/impdp, however for now I need to do what I can to contain the amount of time it takes to process.
    Environment: Oracle 10.2.0.4 (source and destination) on Sun Solaris SPARC v10. We are not using ASM currently. Tablespace is 6 datafiles for a total of 87.5GB, 791 tables, 1924 indexes, 1773 triggers, and 10 LOBs.
    Any help would be greatly appreciated.
    Thanks!

    My reading of this thread was that there was a need to be able to do offline setups when the client had lost oracle lite (we get this on PDAs all the time when they go totally dead), so the CD install is something that can be sent out.
    Any install (CD or otherwise) will be empty in terms of applications and data, not much you can do about that on a CD, but depending on the type of device and the storage possibilities you have you can secure the database and application files seperately. for example on a PDA using the external SD or flash for the data and file storage will keep them when the orace directory is lost from main storage and therefore all thet is needed after the oracle lite recovery is to recreate the odbc file (and possibly polite if you have special parameters). The setting of the crr flags for 'real' data on the server is a trick to bring the database up to date without a total rebuild.
    NOTE if you use SD cards etc. on PDAs/small devices, beware of windows ce/mobile power up differential between main memory and external storage. If you power down in the middle of an update or query, you can get device read/write errors when the device powers up due to processing continuing before the storage media is active

  • Run transportable tablespace

    Hi;
    I have a file system database on linux which is 10g.I want to transport this database to new host asm on 11g.
    I am unable to use transportable database since the endian formats are different. I want to use transportable tablespace feature with rman.
    The database is pretty big. I dont have enough space to do the conversion on the source database.
    If I ship the backup of the database to new host, can I do the conversion on new host ?
    ie:
    run {
    allocate channel t1 type 'SBT_TAPE';
    transport tablespace "USERS"
    Tablespace destination '/ora_backup/tts'
    Auxiliary destination '/ora_backup/tts'
    Datapump directory data_pump_dir
    dump file 'tts_test.dmp'
    Import script 'tts_test.imp'
    Export log 'exp_tts_test.log'

    Ricardo,
    I had given you a link in the other thread of yours. Did you see it? If not , please do. You can do the conversion either on the source or you can ship the files on the target host and can convert there as well. Please see the link since it covers it completely.

  • Transport Tablespace Issues

    hi.. i'm trying to use transport tablespace across the same platforms rather than performing export/import . i'm following the steps in Note:371556.1to exp/imp ASM files.
    i have finished all the steps and successfully transport the tablespace. this process involved only 2 TBS, CC_DATA and CC_INDEXES and the schema is CC. i choose to check the full containment before the export done. but when i count the objects before export and after the import, the count is different. the question is how to make the count of objects is same before and after transport.
    before export
    SQL> select count(*), object_type from user_objects group by object_type;
    COUNT(*) OBJECT_TYPE
    33 SEQUENCE
    3 DATABASE LINK
    55 TABLE
    82 INDEX
    19 SYNONYM
    39 VIEW
    6 rows selected.
    after import
    SQL> select count(*), object_type from user_objects group by object_type;
    COUNT(*) OBJECT_TYPE
    82 INDEX
    55 TABLE
    thanks in advance.

    It's a limitation on transportable tablespace (http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/tspaces.htm#i1007233)
    You cannot transport the SYSTEM tablespace or objects owned by the user SYS. Some examples of such objects are PL/SQL, Java classes, callouts, views, synonyms, users, privileges, dimensions, directories, and sequences.So you need to transfer the views, sequences,etc., one method is using exp/imp.

    Are you,by any chance, running Oracle 9i installation code in an Oracle 10g database?
    If so : why?
    As far as I know you can only transport tablespaces to a database of an identical version, so it looks like this is not going to work.

  • Transport Tablespace via RMAN

    Hii all
    I configured control file autobackup on and take a backup whole database with "backup database;" command and
    RMAN> transport tablespace users tablespace destination 'c:\Transport' auxiliary destination 'c:\Auxi';
    I am receiving ;
    RMAN-03015: error occurred in stored script Memory Script
    RMAN-06026: some targets not found - aborting restore
    RMAN-06024: no backup or copy of the control file found to restore
    In begining lines of rman command I saw that "control_files=c:\Auxi/cntrl_tspitr_ST1_dFcB.f" looks like using unix path format in windows? Have you any idea ?
    Best Regards

    hi
    Yes it is on besides I take backup with "backup database include current controlfile" nothing has changed
    RMAN> show all;
    RMAN configuration parameters are:
    CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
    CONFIGURE BACKUP OPTIMIZATION OFF; # default
    CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
    CONFIGURE CONTROLFILE AUTOBACKUP ON;
    CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
    CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
    CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
    CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
    CONFIGURE MAXSETSIZE TO UNLIMITED; # default
    CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
    CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
    CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
    CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'C:\ORACLE\PRODUCT\10.2.0\DB_1\DATABASE\
    NCFST1.ORA'; # default
    also I have just tested same command on aix platform it works well I think this is related windows platform ?

  • Oracle Upgrade V9 to V10 - Transportable Tablespaces

    Hi,
    I am upgrading a database from Oracle 9i v 9.2.0.6.0 to Oracle 10g 10.2.0.4.0. Both servers are running Windows 2003 Server 32Bit.
    My plan is to upgrade using Transportable Tablespaces. This is what I have done.
    1) exec DBMS_TTS.TRANSPORT_SET_CHECK('XXX,XXX,XXX,XXX,XXX,XXX,XXX,XXX,XXX,XXX,XXX',true); --> This checked out fine.
    2) Set the above tablespaces as read only.
    3) Copied all the datafiles to the new server (2TB)
    4) Did the export: exp 'xxx@xxxx as sysdba' transport_tablespace=y tablespaces=(XXX,XXX,XXX,XXX,XXX ETC...) tts_full_check=y file=c:\EXP.dmp log=c:\exp.log
    5) Here comes the problem: When I do the import it imports the tables with the data and forces me o create the Schemas manually. It does not import the users / packages / views / triggers etc...
    I need to do an export that that will include everything (Creates Schemas, Packages, Views, Triggers, Tables, data).
    I know there is a function FULL=y, this will not work as I do not have an additional 2TB for the export file.
    Can someone please explain how to do this?
    Kind Regards
    Henk

    Welcome to the forums !
    Is there a reason you are using transportable tablespaces ? Would it not be easier to do an in-place upgrade on the current server, then copy/clone the instance to the new server ?

  • Transportable tablespaces for migration and upgrade

    Hello All,
    I'm trying to find out some theory about transportable tablespace and upgrade in a single step. I've to move a DB from a Windows server to a Linux server. Win is running 10.1 and Linux 10.2 . It's possible to use RMAN to migrate the whole database and then on new node run startup upgrade and catupgrd.sql to upgrade catalog ?
    Should work?
    Thanks
    Raj

    The following doc for TDB says :-
    "Note: TDB requires the same Oracle Database software version on the source and target systems; hence, a database upgrade cannot be accomplished simultaneous with the platform migration. However, best practices for a database upgrade, as documented in the Oracle Upgrade Companion, also apply to any planned database maintenance activity, including platform migration."
    http://www.oracle.com/technology/deploy/availability/pdf/MAA_WP_10gR2_PlatformMigrationTDB.pdf
    There is also an Oracle Whitepaper called "Database Upgrade Using Transportable Tablespaces: Oracle Database 11g Release 1" but I am still trying to find a copy.
