In Response To: Re: moving from one server to another (Walter Lowich)

Hi,

if you are sure that database installation/configuration and links are correct you should check if the restore was okay.
For example you could look at the contents of the raw devices on the two servers. Example for HPUX:
dd if=/informix/PS2/sapdata/physdev1/data1 bs=2048 count=2 | xd -c
Compare the output on the two servers and check a few more links/devices.

Regards,
Andreas
