查看锁等待情况 db2pd 使用说明

 

1、查看锁等待情况 db2pd -db [ dbname ] -locks 主要关注Sts列，其中W代表Waiting d:/>db2pd -d test -locks Database Partition 0 -- Database TEST -- Active -- Up 0 days 00:02:21 -- Date 2008-06-24 16:11:26 Locks:

Database Partition 0 -- Database TEST -- Active -- Up 0 days 00:03:27 -- Date 2008-06-24 16:12:32 Transactions:

3、确定 applications 关系，进一步确定应用程序IP等信息 db2pd -db [ dbname ] -appl d:/>db2pd -db test -appl Database Partition 0 -- Database TEST -- Active -- Up 0 days 00:03:43 -- Date 2008-06-24 16:12:48 Applications:
