Oracle EBS 表空间

-- DATA 
这里仅提供查询锁和解锁。有时，锁是正常的，所以杀掉正锁着的进程有一定的风险性。
具体步骤如下：
-- 1.0 查看 holder的进程
SELECT DECODE(request, 0, 'Holder: ', 'Waiter: ') || sid sess,
       id1,
       id2,
       lmode,
       request,
       type
  FROM V$LOCK
 WHERE (id1, id2, type) IN
       (SELECT id1, id2, type FROM V$LOCK WHERE request > 0)
 ORDER BY id1, request;
-- 2.0 看 lock的表
SELECT DOB.OBJECT_NAME,
       VSS.CLIENT_IDENTIFIER,
       LO.SESSION_ID || ',' || VSS.SERIAL#,
       LO.LOCKED_MODE,
       VSS.SERIAL#,
       VSS.ACTION,
       VSS.OSUSER,
       VSS.LOGON_TIME,
       VSS.PROCESS,
       VPS.SPID,
       VSS.*
  FROM V$LOCKED_OBJECT LO, DBA_OBJECTS DOB, V$SESSION VSS, V$PROCESS VPS
 WHERE LO.OBJECT_ID = DOB.OBJECT_ID
   AND LO.SESSION_ID = VSS.SID
   AND VSS.PADDR = VPS.ADDR
   and VSS.SID = ; -- 值去 1.0 sess 字段 holder: 后的数字
   
 -- 3.0 查看状态 SID SERIAL
 select * from v$session where sid = ;-- 值去 1.0 sess 字段 holder: 后的数字
 -- 4.0 如果状态是 INACTIVE 等，酌情kill
 ALTER SYSTEM KILL SESSION ' , ';-- 分别取 3.0 SID SERIAL

-- undo
SELECT a.tablespace_name as tablespace_name,
       to_char(b.total / 1024 / 1024, 999999.99) as Total,
       to_char((b.total - a.free) / 1024 / 1024, 999999.99) as Used,
       to_char(a.free / 1024 / 1024, 999999.99) as Free,
       to_char(round((total - free) / total, 4) * 100, 999.99) as Used_Rate
  FROM (SELECT tablespace_name, sum(bytes) free
          FROM DBA_FREE_SPACE
         GROUP BY tablespace_name) a,
       (SELECT tablespace_name, sum(bytes) total
          FROM DBA_DATA_FILES
         GROUP BY tablespace_name) b
 WHERE a.tablespace_name = b.tablespace_name

-- temp
SELECT A.tablespace_name tablespace,
       D.mb_total,
       SUM(A.used_blocks * D.block_size) / 1024 / 1024 mb_used,
       D.mb_total - SUM(A.used_blocks * D.block_size) / 1024 / 1024 mb_free
  FROM v$sort_segment A,
       (SELECT B.name, C.block_size, SUM(C.bytes) / 1024 / 1024 mb_total
          FROM v$tablespace B, v$tempfile C
         WHERE B.ts# = C.ts#
         GROUP BY B.name, C.block_size) D
 WHERE A.tablespace_name = D.name
GROUP by A.tablespace_name, D.mb_total;

增大表空间

这里仅是改成数据文件自动扩展格式，每个数据文件最大存储32G.

select * from dba_data_files  where tablespace_name = 'XXX’; -- 表空间名称
alter database DATAFILE XX autoextend on next 100M maxsize unlimited; -- 扩展为自动扩展，扩展到最大 32G
