1.  Prepare phase (source data remains online)

    1. Transfer datafiles to destination system

    2. Convert datafiles, if necessary, to destination system endian format

2.  Roll Forward phase (source data remains online - Repeat this phase as many times as necessary to catch destination datafile copies up to source database)

    1. Create incremental backup on source system

    2. Transfer incremental backup to destination system

    3. Convert incremental backup to destination system endian format and apply the backup to the destination datafile copies 

NOTE: In Version 3, if a datafile is added to the tablespace OR a new tablespace name is added to the xtt.properties file, a warning and additional instructions will be required. 

3.  Transport phase (source data is READ ONLY)

    1. Make tablespaces in source database READ ONLY

    2. Repeat the Roll Forward phase one final time

  • This step makes destination datafile copies consistent with source database.

  • Time for this step is significantly shorter than traditional XTTS method when dealing with large data because the incremental backup size is smaller.
