Radoslaw Q1 - it depends -- also on the answer for Q2 Q2 - if the software knows here is a copy your application may just switch to the copy.
In case of PPRC only the HW know and the application does not know it gets errors and may try to recover / restart or just fails . So in this sense i think it is ok for AIX in case the apllication can use it. Frank Krueger From: "R.S." <[EMAIL PROTECTED]> I was told that IBM recommends for p/Series platform software mirroring over hardware based remote copy (like PPRC). Q1. Is it true ? Q2. What are the advanages of using OS features over remote copy solutions provided by DASD hardware ? ---------------------------------------------------------------------- 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
