FW: Refreshing data on a test database
Posted in 1997
Topics: Storage & Space Management, Migration, Import/Export & Data Conversion
I use tbload/tbunload to move my production to test. It is pretty quick =
and can write to disk as well as tape (just create the file on disk =
before tbunload and then use it in the -t parameter)

All your chunk sizes must be identical in order to do a restore. And
the new instance must have the same named (identical paths) pointers
pointing to the same size (although not necessarily identically named)
chunks.

} Is it possible to do this if the chunk names and numbers are the same
} but
} their sizes are different? Our production chunks are larger than our

} environment, but both environments are sufficient in size to cover the

} Another way of asking this is, what needs to be identical to both

} my test system to work?
}
} Thanks for you help.
