Migrate Solaris Based (Big Endian) Oracle 10.2.0.3 Database to HP-UX (Ia64

Migrate Solaris based (Big Endian) Oracle 10.2.0.3 database to HP-UX (ia64 Big endian) platform. Database Details: FINN Size: Approximately 8 TB Datafiles: 2000 files Problem statement: 1) Exp/Imp for TTS Normal transportable tablespaces would not bring objects in the system schema, including components like expression filter, java vm, etc. This would mean that the DBA would have to re install these components and ensure that all the objects on the source are the same with the same status. This method is prone to human errors as there are more that 25,000 application objects 2) RMAN Convert Though this method removes the concerns of the previous method, but converting 2000 datafiles of 8TB size, would take a very very long time to complete. Hence, this cannot be used. 3) RMAN Convert - ONLY tablespace containing UNDO segments (SYSTEM and UNDO) This method is documented in Oracle Note : Cross Platform Database Conversion with same Endian [ID 415884.1] However, there is a bug related to UNDO RMAN convert Bug 8885304 ORA-7445 [ktu_format_nr] during RMAN CONVERT of UNDO tablespace datafile Hence, it was decided to drop the UNDO tablespace on production and create a single file small UNDO tablespace, to avoid this bug as well as cut down on the time required for conversion. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------Kindly let us know if the following steps are valid as per the Oracle Metalink Note : Preactivity 1) Install an configure binaries on HP server 2) Find and install required patches (equivalent of Sun Solaris) on HPserver, as per SR input from Oracle Activity 1) Ensure primary database is in read/write mode(Sun Solaris ) 2) Create a new undo tablespace" 3) Set the UNDO tablespace to the new UNDO (Only keep 500MB)" 4) Drop the older Undo Tablespace including contents and datafiles 5) Unmount partitions from primary to targetSolaris to HP 6) Startup nomount and recreate the controlfileHP 7) Now convert all the system and undo datafiles to a new locationHP 8) Recreate the controlfile with these new file locationsHP 9) alter database open resetlogsHP 10) Create listners, crons etcHP

11) Release system to application user for testing
