對表進行任何操作都不被允許，提示SQLSTATE=57016 SQLCODE=-668 ，原因碼 "7"的錯誤：SQL0668N Operation not allowed for reason code "7" on table XXX.

首先查一下:

db2 ? 57016

SQLSTATE 57016: 因為表不活動，所以不能對其進行訪問。

解決方法為：執行命令：reorg table XXX；即可。

參考原文為：

Operation not allowed for reason code reason-code on table table-name.

Explanation: access to table table-name is restricted. The cause is based on the following reason codes reason-code: 7

The table is in the reorg pending state. This can occur after an ALTER TABLE statement containing a REORG-recommended operation.7

Reorganize the table using the REORG TABLE command (note that INPLACE REORG TABLE is not allowed for a table that is in the reorg pending state).

其中：

reorg table 通過重構行來消除“碎片”數據并壓縮信息，對表進行重組。

runstats on table . 收集表 的統計信息。

reorgchk on table all 確定是否需要對表進行重組，對于對所有表自動執行 runstats 很有用。

>>> reorg 和runstats 都是單個表優化，初始化的命令：

runstats on table administrator.test;

reorg table administrator.test;
