Home -> Community -> Mailing Lists -> Oracle-L -> RE: RE: Double Take and Oracle
Thanks for the input so far. Double-Take works real time so the database is
never down.
I also followed their setup direction to the letter. Problem on our site is
that this product is being used for SQL Server and Exchange (Appears to work
fine there, but Oracle is a beast of another color compared to these "Access
on Steroids" databases), management are insisting for the sake of conformity
that this must work. At ever attempted startup another file gives an error,
most frustrating of all is that there is almost no consistency to the
errors.

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.

Corporate IT THE WOOLWICH ---------------------------------------------------------------------- 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.
