Lewis,
I can understand where Eva is coming from. I had a demo of a similar
product some time ago. Their BIG selling point is that you have a production
server and a backup that is close in time with your production server at half
(or less) the cost of a hot standby. Their reasoning is that you don't have
Oracle running on the standby and consequently don't have to pay Oracle a
license fee for the second server since only one server is running at any point
in time. Logically their point is well taken. Regrettably and understandably
that is NOT Oracle's point of view.

I'm always dubious of these types of products (especially when there are no
reference sites available) and would opt for a batched up standby database
solution (syncing every 5/10/15 minutes or so) myself. I'm not saying
Double-Take is not good - I've got no experience of it and am sorry it's not
any help but you have an option should Double-Take not work correctly.

Hello Esteemed Gurus
Pls advise.......
We are trying to get Double Take to work on our site. Does anyone actually
have this product working???
Salesperson claims Double Take is certified by Oracle - does anyone know?
Where could I find out, other than the company itself?
For those of you who don't know this product pls give your opinion. Double
Take is a software that copies your database files and parameter files etc
across to a disaster recovery machine, bit for bit. At failure of the
production the recovery becomes the production system and starts up the
database. Basicly the datafiles are still open??
We get the following error when we start up the database on the recovery
system in tests:
ORA-01172: recovery of thread 1 stuck at bloack 176624 of file 2.
I would just like to add that when this happens we resync the databases and
try again to test and guess what - it is the turn of file 3 to give the
above error, and so back and forth we go.
To say the very least I am frustrated beyond comprihension. To make this
worse there is no one else in South Africa that uses this software with
Oracle, apparently in France. Convienant - I'd say. So I have no one to turn
to about this. (Apparently it works well with MSSQL). Anyone any ideas?
The Enviroment is Windows 2K SP3.
Oracle 817
