Oracle Database Discussions

Hi all,

I am deleting the records in a table by the command

delete from tablename where create_dt >= trunc(sysdate-1,'mon');

Now i want to insert the records by
insert into tablename select * from tablename@databaselink where create_dt >= trunc(sysdate-1,'mon');

But this statemnt gives me an error
ORA ERROR at line 1:
ORA-03113: end-of-file on communication channel

When i looked the alert log file i came to know this

INSERT INTO tablename SELECT * FROM tablename WHERE CREATE_DT >= trunc(sysdate-1,'MON')
*
i looked at the alert log file and i can see the error message
