Hi,
my requirement is to create two datasource which points to two different schemas of oracle 10 g database.
In a single transaction i may be in requireemnt of contacting both the datasource to get respective db connection and do a insert/update.
I created two datasources A and B which use Oracle 9 thin driver.
When my application starts my app is able to get connection of datasource A and unable to get connection on datasource B. what may be the problem ??
both uses Oracle non-XA driver with one phase commit;
Let me know how to connect to two diff datasources in a single transaction.

Do you get like any error for second datasource like jndi lookup failed or exactly what do you see error. If I understand your usecase:
DataSource_1 -> Uses ConnectionPool_1 -> DB Schema_1
DataSource_2 -> Uses ConnectionPool_2 -> DB Schema_2.
So in your java application, I guess you are using JNDI Lookup and pass above Datasources unique JNDI names, and get 2 instances. I mean you have like 2 sets of Jndi lookup code to get 2 connection objects. This looks pretty straight forward. Does not matter what drivers you use.
Are you reusing any objects in your code, like have a single connection object and then close it and try to recycle it for second something like that...If not, check for any errors in the log files.
