Analyze a synonym

Question

Hi,
I am facing a problem in analyzing the synonym.
I have created a table abc in schema1. Granted all the privilleges on that table to schema2. In schema2, I have created synonym xyz for table schema1.abc.
When I analyze the synonym xyz using the following statement.
DBMS_STATS.GATHER_TABLE_STATS(OWNNAME=> UPPER(P_SCHEMA_OWNER), TABNAME=> UPPER(P_OBJ_NAME), ESTIMATE_PERCENT=> dbms_stats.auto_sample_size, degree=> 2, CASCADE=> TRUE);
DBMS_OUTPUT.put_line ('Statistics gathered for object ''' || UPPER(P_SCHEMA_OWNER)|| '.' || UPPER(P_OBJ_NAME) || '''');
But I am getting the following error:
ORA-20000: Object does not exist or insufficient privileges to analyze
Is it possible to analyze the synonym.??
Thanks,

Well, that's obviously wrong: XYZ is not a table. This is quite easy to demonstrate. Given a user B with privileges on a table AP owned by A...
SQL> conn b/b
Connected.
SQL> create synonym xyz for a.ap;
Synonym created.
SQL> exec dbms_stats.gather_table_stats ('A', 'AP',ESTIMATE_PERCENT=> dbms_stats.auto_sample_size)
PL/SQL procedure successfully completed.
SQL> exec dbms_stats.gather_table_stats ('B', 'XYZ',ESTIMATE_PERCENT=> dbms_stats.auto_sample_size)
BEGIN dbms_stats.gather_table_stats ('B', 'XYZ',ESTIMATE_PERCENT=> dbms_stats.auto_sample_size); END
ERROR at line 1:
ORA-20000: Unable to analyze TABLE "B"."XYZ", insufficient privileges or does
not exist
ORA-06512: at "SYS.DBMS_STATS", line 10061
ORA-06512: at "SYS.DBMS_STATS", line 10084
ORA-06512: at line 1
SQL> In other words, it works with the table but not the synonym.
Note that in order to make this work at all I had to grant the ANALYZE ANY system privilege to B. This is because gather statistics requires writing to the data dictionary tables and that's normally the prerogative of SYS.
