Hi all.
We want to convert one of largest tablespaces to RPN. And as we know this requires a REORG off the whole tablespace.
Now we are calculating the DASD requirements.
The tablespace in question has 2500 partitions and takes, inclusive its indexes, about 29 Tb on disk.(22 Tb for data, 7 Tb for indexes).
My calculation so far is:
1) 29 Tb on the database pool for the shadow tablespace..
2) 22 Tb for the UNLOAD dataset.
3) 22 Tb for the image copie. (must it be one dataset ?)
4) Some workspace for building the indexes but we intent to use RECLUSTER NO so no data needs to be sorted.
ThIs is a real challenge for our DASD guy.
Does anybody see an opportunity to save some space any where.
And thought is welcome
P.S. we don't have tape (or VTS) anymore.
