A: 是因為 Oracle 的 bb_bb60_data_file 已經到達 2G 了，需要新增加一個 Data file ，處理的方式如下：

set linesize 120 SQL> SELECT tablespace_name, ROUND(SUM(total_mb)-SUM(free_mb)) CUR_USE_MB, ROUND(SUM(total_mb)) CUR_SZ_MB, ROUND((SUM(total_mb)-SUM(free_mb))/SUM(total_mb)*100) CUR_PCT_FULL, ROUND(SUM(max_mb) - (SUM(total_mb)-SUM(free_mb))) FREE_SPACE_MB, ROUND(SUM(max_mb)) MAX_SZ_MB, ROUND((SUM(total_mb)-SUM(free_mb))/SUM(max_mb)*100) PCT_FULL FROM ( SELECT tablespace_name, SUM(bytes)/1024/1024 FREE_MB, 0 TOTAL_MB, 0 MAX_MB FROM dba_free_space GROUP BY tablespace_name UNION SELECT tablespace_name, 0 CURRENT_MB, SUM(bytes)/1024/1024 TOTAL_MB, SUM(DECODE(maxbytes,0,bytes, maxbytes))/1024/1024 MAX_MB FROM dba_data_files GROUP BY tablespace_name) GROUP BY tablespace_name;
