Oracle Database Discussions

Hi all!

I am quite new to standby databases, but I managed to sucessfully setup logical standby (11g on linux).
However, I got some problem - when I try to insert some data into Primary DB using simple JDBC statements, I sometimes get exception:

java.sql.SQLException: ORA-16224: Database Guard is enabled

And this happens not all the time - sometimes I can insert and commit, but sometimes I get exception.
This never happens when I am trying to insert data directly from sqlplus or TOAD.

looks to me like java application sometimes is connecting to standby database.

any suggestions?

Thanks
