Re: Checkpoint Blocked on Restore?
Posted in 2005
Some additional information/
The restore ran, to a point. There is actuall a problem on both
servers with the instance configuration.
I started the restore and walked away. Four and half hours later, it
completed...restoring a total of 5.8 gigabytes. However, some of the
dbspaces did not get restored due to incorrect instance configuration
(permissions on dbspaces incorrect).
Bottom line,we will correct the instance problem, then see what
happens. No need for further response.
Thanks to those that did respond.
