PL/SQL: ORA-04052: error occurred when looking up remote object.

Question

Hi All,
I'm getting the following error message while executing a PL/SQL Block.
PL/SQL: ORA-04052: error occurred when looking up remote object UPLDUSER.filestatushistory@FTS
ORA-00604: error occurred at recursive SQL level 1
ORA-03106: fatal two-task communication protocol error
ORA-02063: preceding line from FTSStatement
declare
v_coun number;
begin
select count(*) into v_coun
from updluser.filestatushistory@fts;
end;Back ground of the situation as follows,
My DataBase version 10.2.0.3 DB Name :DB1
Table Owner : UPLDUSER
Table Name : FILESTATUSHISTORY
I have a report user on the same database and I have grant all on the above table to report user
Report User : RPT_FTS
SQL> GRANT ALL ON FILESTATUSHISTORY_V TO RPT_FTS;Now Please find the below database details where I'm getting subjected error.
Database version : 9.2.0.8
DB Name : DB2
User Name : RPT_REPORTS
I Have create a dblink from RPT_REPORTS to RPT_FTS on DB1 and the dblink works fine. But getting the above error while running it.
but When I do the same other 10.2.0.3 db , the above PL/SQL block works fine without any problem.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Now the strange about this is that I have Created a new table on DB1 db like below;
SQL> CREATE TABLE UPLDUSER.ABC AS SELECT * FROM FILESTATUSHISTORY;and retry my code on DB2 (9.2.0.8) after changing the table to ABC and it worked. Now I don't know whats wrong with a original table(FILESTATUSHISTORY).
To over come the problem and a work-a-round method I create a view on the DB1 (RPT_FTS) like the below
SQL> CREATE VIEW FILESTATUSHISTORY AS SELECT * FROM UPLDUSER.FILESTATUSHISTORY;and was able to run the PL/SQL block Remotely.
Just wants To know what whould have been the cause for this .
Cheers

Hi Kanchana,
Perhaps following link of google search has answer to your query
ORA-04052. The search result contains some useful articles whose URLs I shan't post in the forums.
HTH!
