Oracle does have support for clustered databases, so I'd recommend using that for this. Clustering is really what is intended to solve this sort of problem.

If it was something other than Oracle, you could use something like the C-JDBC driver.

I'm using oracle DB.
For stored procedures, I can create 2 db links to the 2 db (life and backup) on my schema, and inside the stored procedure I can do the following:
Retrieve the data from the life one,
If no data found then retrieve the data from the backup one

Which database are you using? Some database drivers are a bit inane
by default and don't reconnect to the database automatically. For
these there is usually a JDBC uri parameter to turn on this option.

Use stored procedures to get the data? I have no idea how this would
help with a lost connection problem... but it certainly does follow
the what has been the database design and DBA agenda for the first
few decades of the life of databases... ;)

Dear all



I'm facing a problem with my DB connections, I have 2 DBs, one life
and
the other is Backup.

Sometimes, the life one due to unexpected error shut down suddenly,
and
all the pages in OFBiz related to this DB give an error.



How can I check if the connection is still available or not, and in
case
of unavailability, how can I connect to the backup DB in a transparent
way??

The DBA advised me to retrieve the data through stored procedures, but
as I know, the stored procedure is not supported by OFBiz.



Please advice



Kind regards
