Symptoms
When running awinstall or via sql you try to change the name of the Master or agent you receive the following error:
Cause
ORA-00001 is common when: a program tries to insert a "duplicate" row in a table," and that, "when a unique constraint is violated the row is not added to the table."
Resolution
Please log into sqlplus as the Oracle Applications Manager user and run the following sql:
select * from so_operators;
Please just make sure your not trying to update any value to that which is all ready there(ie renaming the master to the name of an existing agent).
