Please make sure the DB link you are using is Public and Shared, if the DB link is not Public and Shared it will throw an Exception ORA-24777: use of non-migratable database link not allowed. But if you try to run the same query directly on DB with out using any Java or XA transaction it will work fine.

The DB link is shared and public. System is connecting to that DB and allow user to access, but on a peak access to that DB system is throwing that error. Then system requires restart of all the services to proceed further.

We are using dblink through unixtoodbc driver to get postgres data on oracle db. Only one of my client(using XA transaction) is getting error "ORA-24777: use of non-migratable database link not allowed" while accessing the data from my oracle db (where i am uning dblink to get postgres data).

I have changed dblink to shared dblink, after this when i access the dblink data my oracle system got hanged and i need to restrat the oracle 10g server and reconfigure the dblink to public only.  Please suggest the root cause and possible resolution for same.
