Problems with database synchronization (ORA-04062)

Question

I have the master database:
db_master
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi
PL/SQL Release 10.2.0.3.0 - Production
CORE     10.2.0.3.0     Production
TNS for Linux: Version 10.2.0.3.0 - Production
NLSRTL Version 10.2.0.3.0 - Production
and replica database:
db_replica
Oracle Database 10g Release 10.2.0.3.0 - 64bit Production
PL/SQL Release 10.2.0.3.0 - Production
CORE     10.2.0.3.0     Production
TNS for Linux: Version 10.2.0.3.0 - Production
NLSRTL Version 10.2.0.3.0 - Production
the master and replica databases are installed at different hosts
At db_master:
1. I create table TEST
CREATE TABLE TEST (ID NUMBER PRIMARY KEY);
2.Then create materialized view log on TEST
CREATE MATERIALIZED VIEW LOG ON TEST;
At db_replica:
1. create dblink MASTER to db_master
2. create materialized view
CREATE MATERIALIZED VIEW MV_TEST REFRESH FAST AS SELECT * FROM TEST@MASTER
At db_master:
1.Insert some test values to TEST
INSERT INTO TEST VALUES (1);
INSERT INTO TEST VALUES (2);
INSERT INTO TEST VALUES (3);
COMMIT;
At db_replica:
1. call in job (every 10 sec) DBMS_MVIEW.REFRESH(‘MV_TEST’), or manually:
begin
DBMS_MVIEW.REFRESH('MV_TEST');
end;
sometimes (not at every call the below error callstack appears)
17:07:22 ORA-04062: timestamp of package "SYS.DBMS_SNAPSHOT_UTL" has been changed
17:07:22 ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2254
17:07:22 ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2460
17:07:22 ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2429
17:07:22 ORA-06512: at line 4
Please, help me solve this problem, what cause ORA-04062?

Hi,
Try setting global_name parameter to true in init.ora
