RABNSIZE from 3 to 4

Hello Fellows,

I would like to know if I can modify the RABNSIZE from 3 to 4 without to define the data base again.
Thanks in advanced

My best Regards,

Unfortunately no, ADADEF DEFINE is the only way to change the RABNSIZE.

Best regards,


Wolfgang, Thank you very much indeed!

My best regards,


I just want to confirm the procedure to change the database from 3 to 4 rabn. Is ADADEF the only utility required to perform this exercise or are there other steps that need to be followed except taking the full backup?

Will appreciate your help.


Hi Kugh

No, ADADEF is not all you will need. You need to:

  1. use the ADAORD RESTRUCTUREDB utility to offload all of the data to a dataset with ddname DDFILEA
  2. define the database with ADADEF (use OVERWRITE)
  3. put all the data back in using the ADAORD STORE.
