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. 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 <tablename> 通過重構行來消除“碎片”數據並壓縮信息，對表進行重組。
runstats on table <tbschema>.<tbname> 收集表 <tbname> 的統計信息。
reorgchk on table all 確定是否需要對表進行重組，對於對所有表自動執行 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;
