We would FAVER EXPORT the DSN to tape, then FAVER IMPORT it back. The actual job is more complicated than that. We use "wild cards" to dump multiple VSAM files to tape for backup purposes. We then run T-REX to list all of those with a large number of CA splits. We message that report in the next step to create FAVER control cards to IMPORT selected VSAM files. FAVER IMPORT, like IDCAMS IMPORT will delete and redefine the entire VSAM SPHERE based on the cluster names given. The cost to convert from FAVER in terms of labour will be immense. So I hope CA comes through for us. My boss has been trying hard to drive our costs down because that helps save jobs. -- John McKown Maranatha! <>< ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
