NAME

xttdriver.pl - Cross Platform Transportable Tablespace DRIVER perl

script

DESCRIPTION

The script that is run to perform the main steps of the XTTS with Cross

Platform Incremental Backups procedure.

VERSION

2.0

NOTES

In version 2 12C options have been added which supports

"backup for transport" and "restore from platform"

In version 1.4 two new options -P and -G have been added.

In the current flow the datafiles are transported using a staging area

in the source and desination. This has been eliminated by using

dbms_file_transfer.

Parallelism is supported for rollforward if rollparallel is set

Bug Fixes

==========

Apr 24 2015 [Version 2]

----------------------------

1. Bug 20916691: --backup option broken

2. Bug 21028174: Add message when -L option is used

Nov 19 2014 [Version 2]

------------------------------

Project 47110: New options have been added

1. --backup

2. --restore

3. --bkpincr

4. --bkpexport

5. --resincrdmp

6. Bug 20192155: Fix for ORA-15126

7. Added --version option to give version

8. Added multiple source and destination directory support in getfile.

9. Removed putfile code

Nov 14 2014 [Version 1.4.2]

------------------------------

1. Enhancement: Added getparallel option to transfer datafiles in

parallel.

March 24 2014 [Version 1.4.1]

------------------------------

1. 18456868 - Made sure sqlplus and rman is present in the PATH

2. 18456834 - Added new option -F/--propfile to pass the location

of properties file if required. This was requested by EM.

3. 18459238 - dfcopydir was not required when we run using -G

option. The checking has been enhanced.

4. Even when convert instance is used, the -G should be run only

from destination instance and not the conversion instance

5. Impdp added ';' at the end which resulted in error. Fixed this

6. Added more debugging messages

7. Do more error checking before proceeding to next steps

8. Bug 17819946 - When number of tablespaces is more, the length

of list exceeds 2499 and fails. This is also fixed

9. If debug option is set to more than 1 the temporary files are

preserved. Otherwise it is deleted.

10. Bug 18797439 - Add new option -I/--propdir. All required files

will be picked from the runtime location of xttdriver.pl

11. Clean up the code such that the temp files are more readable

and can be mapped to backups
