The official "supported" method to move a RACF database is by using the utility IRRUT400. This utility provides the proper ENQ and locking mechanisms to prevent updates to the database while the copy is in progress. And, it's simple enough to use.
However, if you can afford the downtime, and have a 2nd "completely" independent operating system image, the database can be moved using FDR/DFSMSdss and/or IEBGENER/ICEGENER/SYNCGENR. This is officially "unsupported", but works, provided the databases are not in use (in any way) while the copy is in progress. My opinion, always use IRRUT400. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
