DB2 的SQLState=40001 和SQLState=55039解决方案

解决55039故障(SQL0290N 不允许访问表空间,SQLState 55039)

1、db2 list tablespaces show detail;
Tablespace ID                        = 2
Name                                 = USERSPACE1
Type                                 = Database managed space
Contents                             = All permanent data. Large table space.
State                                = 0x0004
   Detailed explanation:
     Quiesced: EXCLUSIVE
Total pages                          = 77824
Number of quiescers                  = 1
   Quiescer 1:
     Tablespace ID                    = 2
     Object ID                        = 180

2、--找到有问题的对象TabName例如(USERINFO)
--select * from  SYSCAT.TABLES WHERE tableID='有问题的对象ID'
select * from  SYSCAT.TABLES WHERE tableID='267'

--3、db2 QUiesce  tablespaces  for table 对象名字  reset;
db2 QUiesce  tablespaces  for table USERINFO reset;

模拟55039故障
db2 QUiesce  tablespaces  for table USERINFO  Exclusive;

长久做法建议修改数据库参数 
修复这四个参数:DLCHKTIME   MAXLOCKS  LOCKLIST  LOCKTIMEOUT
db2 update db cfg for zhptdb using LOCKTIMEOUT 3600 immediate;

快速解决方案:
1、查找持有X锁的会话
db2 get snapshot for locks on zhptdb
Application handle                         = 16037(会话句柄)
Application ID                             = 10.10.3.142.42248.150213023522
Lock Object Name            = 5
Object Type                 = Row
Tablespace Name             = HGQW_TBS
Table Schema                = HGQW
Table Name                  = TB_HGQW_QWZH_XCXSCL
Mode                        = X  (常见的锁类型  X:全称exclude 、 S:全称share)
2、db2 'force application(会话句柄)'
db2 'force application(16037)'
