解决如下：

SQL> select tablespace_name,bytes/1024/1024 from dba_free_space where tablespace_name='STATSPACK1';
TABLESPACE_NAME BYTES/1024/1024
------------------------------ ---------------
STATSPACK1 63.484375

SQL> SELECT segment_name, owner, EXTENTS, max_extents,segment_type
2 FROM dba_segments
3 WHERE segment_name ='STATS$SQL_SUMMARY';

SEGMENT_NAME OWNER EXTENTS MAX_EXTENTS
-------------------- ------------------------------ ---------- -----------
SEGMENT_TYPE

STATS$SQL_SUMMARY PERFSTAT 505 505
TABLE


SQL> ALTER table PERFSTAT.STATS$SQL_SUMMARY STORAGE ( MAXEXTENTS 8192);
Table altered.

SQL> set linesize 1000
SQL> SELECT segment_name, owner, EXTENTS, max_extents,segment_type
2 FROM dba_segments
