SQL0290N表空间状态独占处理问题

核心提示：今天一个同事报告一个问题，表都不能使用了,检查了一下，SQL0290N表空间状态独占处理问题，发现问题 db2 => select * from test ACTNO ACTKWD ACTDESC -- -- SQL0290N Table space access is not allowed. SQLSTAT

　　今天一个同事报告一个问题，表都不能使用了,检查了一下，发现

问题 db2 => select * from test

ACTNO ACTKWD ACTDESC

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

SQL0290N Table space access is not allowed. SQLSTATE=55039

其他表也不能使用

在db2cc里查看表空间状态为： 停顿的独占

解决方法：

到命令行状态，首先connect 到需要处理的数据库

◆1、db2 => list tablespaces show detail 显示表空间状态

Tablespaces for Current Database

Tablespace ID = 0

Name = SYSCATSPACE

Type = System managed space

Contents = Any data

State = 0x0000

Detailed explanation:

Normal

Total pages = 2519

Useable pages = 2519

Used pages = 2519

Free pages = Not applicable

High water mark (pages) = Not applicable

Page size (bytes) = 4096

Extent size (pages) = 32

Prefetch size (pages) = 32

Number of containers = 1

Tablespace ID = 1

Name = TEMPSPACE1

Type = System managed space

Contents = System Temporary data

State = 0x0000

Detailed explanation:

Normal

Total pages = 1

Useable pages = 1

Used pages = 1

Free pages = Not applicable

High water mark (pages) = Not applicable

Page size (bytes) = 4096

Extent size (pages) = 32

Prefetch size (pages) = 32

Number of containers = 1

Tablespace ID = 2

Name = USERSPACE1

Type = System managed space

Contents = Any data

State = 0x0004 这个代码意义就是“停顿的独占”，正常状态为0x0000，

非0就是有问题，都可以用下面方法解决。

Detailed explanation:

Quiesced: EXCLUSIVE

Total pages = 687

Useable pages = 687

Used pages = 687

Free pages = Not applicable

High water mark (pages) = Not applicable

Page size (bytes) = 4096

Extent size (pages) = 32

Prefetch size (pages) = 32

Number of containers = 1

Number of quiescers = 1 注意下面几行

Quiescer 1:

Tablespace ID = 2

Object ID = 50 “object id是造成死锁表的id”

◆2、db2 => select tabname from syscat.tables where tableid=50 通过所住的id号找出是哪个表。

TABNAME

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

SYSINDEXEXTENSIONPARMS

TEST 就是这个表

2 record(s) selected.

◆3、db2 => quiesce tablespaces for table test reset 执行该命令清除错误的状态

DB20000I The QUIESCE TABLESPACES command completed successfully.

◆4、重新select，问题解决

◆5、比较常见导致改种问题的原因是，非正常的中止正对表进行的操作，导致对表空间的使用没有正常的释放。
