HDR

hi,

We are trying to setup HDR (using IDS 7.31UD3X5a) on NCR UNIX.
The two enviroments are configured identically. HDR starts successfully
(We also created databases and table and everything works fine),
when we try to simulate a failure on the primary (onmode -ky), then the
secondary is manually set to standard. (Logical logs are backed up for
both the primary and the secondary).

When we are changing the failed server to primary (having also set
the secondary back to secondary) and applying the logs, the server
starts in fast recovery and sits there for ever.

Below is the message logs file:
