Title: RE: Standby Database

Shareplex is a great tool, i have heard anecdotally. Of course, it ain't cheap, either.

 

 

Both facts need to be addressed.

 

 

Is there any interest in sharing that kind of sales information? For, say, a Sun 6500, 12 processors, 8GB RAM,

"shareplexing" to another box of same type.......

 

 

Just a question.

I usually don't do these kind of posts... but I've seen a lot of activity on this topic lately. 

What is really the problem we are trying to solve here?  Maybe we are using the wrong tool.  

If you are looking for data protection in the event of a failure, or disaster... Or if you are trying to create a real time reporting instance. And you are using standby databases... there is a better solution.   

We provide a product called SharePlex for Oracle... it continually scans the online redo logs for any transactions on the tables that are critical to your environment.  It takes these transactions, and sends them to a target machine over TCP communication, and posts them via standard Oracle SQL.  The target system is completely open and available, while we are posting to it, for reporting and/or verifying that the data is there and available for use in case of a failure or disaster at the primary site. 

It can even be used in a peer to peer replication scheme as well.

Sorry about the 'sales announcement'  but this list is for helping people, and trying to solve their problems... I see this as a solution.

Quick question.  Is it a fair statement to say that using Oracle's hot
standby database allows you recoverability up to the last archive log, but
would NOT recover to the latest redo log (prior to a log switch).  In other
words, the potential to lose transactions is very high if you depend on this
for failover (not good for e-commerce type databases).  Would it be possible
to somehow mirror redo logs across to the failover server and apply them
when activating the standby database, or is the only real solution
clustering or something like DoubleTake?

Am I making sense?

Thanks,

Ed
