Answer / s
1.Unload the DB
2.Delete/Define Database Datasets (if space allocation
needs to be changed make necessary changes)
3.Change the DBD to calculate how many RAPS is needed.
RAPS is the number of DB records that can be stored in a
Block, say 8KB Blocksize. Say you have 1000 byte records
and 16,000 records 8*1024/1000= 8. Relative Block Number
(RBN) is the number of blocks in the Root addressable area
= 16000/8 = 2000. Add some % to these blocks as free space,
say 2500.
Make changes to DBD. RMNAME(DFSHDC40,8,2500)
4.Reload DB with new DBD.
5.Use other utilities to rebuild logical relationships and
secondary indices.
6.Image Copy the DB.
