V4 Reduce Transportable Tablespace Downtime using Cross Platform Incremental Backup (Doc ID 2471245.1)

    This article covers the steps needed to use V4 Cross Platform Transportable Tablespaces (XTTS) with RMAN incremental backups to migrate data between systems that have different endian formats, with the least amount of application down time.

the V4 procedures for Cross Platform Incremental Backup which can be used with 11.2.0.4 and higher.  This new procedure is simplified version of previous XTTs versions.  This version has the following differences:

• this procure uses simplified commands.  One command (--backup) for the source and one command (--restore) for the destination.

• this procedure requires only one file to be copied between the source's and destination's $TMPDIR (res.txt). 

• this procedure will automatically resolve added datafiles with no additional intervention.  

• this procedure allows for multiple incremental backups taken off the source without running the recovery.  After which, recovery will be of all the incremental backups in the destination at once.

The earlier versions of this procedure are still available in:

11G - Reduce Transportable Tablespace Downtime using Cross Platform Incremental Backup (Note 1389592.1)
12C - Reduce Transportable Tablespace Downtime using Cross Platform Incremental Backup (Note 2005729.1)

Consider using the new release of this procedure, version 4. This version has drastically simplified the steps and procedure. Before proceeding, review:
V4 Reduce Transportable Tablespace Downtime using Cross Platform Incremental Backup Note 2471245.1

No bug fixs or diagnostics will be conducted on this older version of XTTs.   Unless absolutely necessary, only V4 of XTTs should be used.
