Server Administration :: Granted Privileges But Not Able To See In DBA_SYS_PRIVS Table

I have been granting "ALTER ANY MATERIALIZED VIEW" to a role but not able to see the same granted in DBA_SYS_PRIVS.

I have used the image for the first time, so pasting the sql prompt output as well:

SQL> select * from v$version where banner like 'Oracle%';

BANNER
----------------------------------------------------------------
Oracle9i Enterprise Edition Release 9.2.0.5.0 - 64bit Production
SQL> grant ALTER ANY MATERIALIZED VIEW to OPS_1ST_LINE;

Grant succeeded.

SQL> select * from dba_sys_privs where grantee = 'OPS_1ST_LINE';

GRANTEE PRIVILEGE ADM
------------------------------ ---------------------------------------- ---
OPS_1ST_LINE CREATE SESSION NO
OPS_1ST_LINE ALTER ANY SNAPSHOT NO

SQL> commit;

Commit complete.

SQL> select * from dba_sys_privs where grantee = 'OPS_1ST_LINE';

GRANTEE PRIVILEGE ADM
------------------------------ ---------------------------------------- ---
OPS_1ST_LINE CREATE SESSION NO
OPS_1ST_LINE ALTER ANY SNAPSHOT NO

SQL> SELECT * FROM DBA_SYS_PRIVS WHERE PRIVILEGE = 'ALTER ANY MATERIALIZED VIEW';

no rows selected..why is this grant not been shown. Is "ALTER ANY MATERIALIZED VIEW" not present for Oracle 9i database.
