db2如何确定某张表是否有锁？

 转自： http://www.db2china.net/club/archiver/tid-10129.html

 参考：----查看SAMPLE库上表的锁数量

SELECT TABSCHEMA, TABNAME, COUNT(*) AS NUMBER_OF_LOCKS_HELD 

   FROM SYSIBMADM.LOCKS_HELD 

   --WHERE DB_NAME = 'SAMPLE' 

   GROUP BY DBPARTITIONNUM, TABSCHEMA, TABNAME

----查询数据库锁表信息

db2 "select agent_id, tabschema,tabname from sysibmadm.snaplock"

----查看锁等待

SELECT SMALLINT(AGENT_ID) AS WAITING_ID,       SUBSTR(APPL_NAME, 1,10) AS WAITING_APP,       SUBSTR(AUTHID,1,10) AS WAITING_USER,       SMALLINT(AGENT_ID_HOLDING_LK) AS HOLDER_ID,       LOCK_MODE AS HELD,        LOCK_OBJECT_TYPE AS TYPE,        LOCK_MODE_REQUESTED AS REQUEST FROM SYSIBMADM.LOCKWAITS

查看锁表信息

-------------

SELECT substr(TABSCHEMA,1,10), substr(TABNAME,1,20), COUNT(*) AS NUMBER_OF_LOCKS_HELD FROM SYSIBMADM.LOCKS_HELD  GROUP BY DBPARTITIONNUM, TABSCHEMA, TABNAME
