ORA-04052: error occurred when looking up remote object SYS.DBMS_SNAPSHOT

Question

Hello everyone,
When I tried to create a materialized view with refresh fast mode, I encountered following error message.
The MV log has been created on my_table like this:
create materialized view log on my_table
tablespace data3
with rowid, sequence
including new values;
The database link has been created like this:
CREATE PUBLIC DATABASE LINK my_db
CONNECT TO myname
IDENTIFIED BY mypassword
USING 'my_db';
Could anybody please let me know why I can not create MV with refresh fast? What I did wrong?
Thanks in advance!!!

No, you cannot apply a patch to XE. Basically the XE internal code is the same as for any other edition. That means is there a bug, you have it in XE,too. To get patches you need a licence for metalink/My Oracle Support. But even you would have one, it wouldn't help you, because Oracle does not provide patches for XE.
That's the 'price' you have to pay for this free edition.
