have a Form connecting to 188.8.131.52 database and has a database link to 10.2.0.4 When you try run the report, the following error occurs:
ORA-01041: internal error. Hostdef extension doesn't exist
the databases are open and running!
1) Please check for alert.log file for both databases and post any error message you getting there while running the report ?
2) Check the listener logs for 10g db, to see if there are any error message in log while running report ?
3) what is the output, if you just select from the DBlink you using in report ?
select * from dual@<dblink_connecting 9iand10gdb>
Refer to MOS Note 429252.1
The problem is caused by a bug.
Workaround is to build a local view for the remote table and use that view in the report.
P.S. if this answers your question, mark the thread as answered. Thanks
