System view is gone!

Question

Hi all,
I want to create a view with a script as following,
CREATE VIEW DP_STATISTIC AS
SELECT 'S' STAT_TYPE, STATISTIC# STAT_NUM, NAME STAT_NAME FROM V$STATNAME
UNION ALL
SELECT 'E' STAT_TYPE, EVENT# STAT_NUM, NAME STAT_NAME FROM V$EVENT_NAME;
It comes out with an error message,
ERROR at line 2:
ORA-00980: synonym translation is no longer valid
And, I try to see the object and it is not there,
SQL> desc V$STATNAME
ERROR:
ORA-04043: object SYSTEM.V_$STATNAME does not exist
How can I brin it back?
from $ORACLE_HOME/rdbms/admin , should I run sql script from this directory?
and if so, what scripts should I run?
thanks in advance!

Hi,
Since V$STATNAME and V$EVENT_NAME are synonyms, you need to give grant select on V_$STATNAME and V_$EVENT_NAME :
  1* select * from dba_synonyms where synonym_name in ('V$STATNAME', 'V$EVENT_NAME')
SQL> /
OWNER                          SYNONYM_NAME
TABLE_OWNER                    TABLE_NAME
DB_LINK
PUBLIC                         V$STATNAME
SYS                            V_$STATNAME
PUBLIC                         V$EVENT_NAME
SYS                            V_$EVENT_NAMEWith user H89UCBAC :
SQL> CREATE VIEW DP_STATISTIC AS
  2  SELECT 'S' STAT_TYPE, STATISTIC# STAT_NUM, NAME STAT_NAME FROM V$STATNAME
  3  UNION ALL
  4  SELECT 'E' STAT_TYPE, EVENT# STAT_NUM, NAME STAT_NAME FROM V$EVENT_NAME;
SELECT 'S' STAT_TYPE, STATISTIC# STAT_NUM, NAME STAT_NAME FROM V$STATNAME
ERROR at line 2:

Grant succeeded.With user H89UCBAC :

View created.
SQL> select count(*) from DP_STATISTIC;
