 SQL0668N  Operation not allowed for reason code "7" on table "TIMETRAC.ROLE".
 SQLSTATE=57016
 
[timetrac@viper01 ~]$ db2 ? SQL0668N


 SQL0668N  Operation not allowed for reason code "" on table
       "".

 Explanation:

 Access to table "" is restricted. The cause is based on the
 following reason codes "":

 1

          The table is in the Set Integrity Pending No Access state. The
          integrity of the table is not enforced and the content of the
          table may be invalid. An operation on a parent table or an
          underlying table that is not in the Set Integrity Pending No
          Access state may also receive this error if a dependent table
          is in the Set Integrity Pending No Access state.


 2

          The table is in the No Data Movement state. When in this state,
          operations that cause data movement are disallowed. Data
          movement operations include REDISTRIBUTE, update of database
          partitioning key, update of multidimensional clustering key,
          update of range clustering key, update of table partitioning
          key and REORG TABLE.


 3

          The table is in the Load Pending state. A previous LOAD attempt
          on this table resulted in failure. No access to the table is
          allowed until the LOAD operation is restarted or terminated.


 4

          The table is the Read Access state. This state can occur during
          on-line LOAD processing (LOAD INSERT with the READ ACCESS
          option), or after an on-line LOAD operation, but before all
          constraints have been validated in the newly appended portion
          of the table using the SET INTEGRITY statement. No update
          activity is allowed on this table.


 5

          The table is in the Load In Progress state. The LOAD utility is
          currently operating on this table, no access is allowed until
          the LOAD is finished.


 6

          Materialized query tables that reference a nickname cannot be
          refreshed in ESE.

 7

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

8
          The table is in the alter pending state. This can occur when
          using the table in the same unit of work as an ALTER TABLE
          statement containing a REORG-recommended operation.
 9
          The table is in Redistribute Pending state. The REDISTRIBUTE
          utility is not completed on this table, no access is allowed
          until the REDISTRIBUTE is finished.
 10
          The table is the source table for an ongoing ADMIN_MOVE_TABLE
          operation. The attempted operation is restricted until the move
          is completed or canceled.
 User response:
 1
          Execute the SET INTEGRITY statement with the IMMEDIATE CHECKED
          option on table "" to bring the table out of the
          Set Integrity Pending No Access state. For a user maintained
          materialized query table, execute the statement with the
          IMMEDIATE UNCHECKED option instead of the IMMEDIATE CHECKED
          option.
 2
          Execute REFRESH TABLE statement on the dependent immediate
          materialized query tables and staging tables of table
          "". The contents of these dependent immediate
          materialized query tables and staging tables can be
          incrementally maintained from the appended data of
          "" through previous LOAD INSERT operations and from
          the attached data of "" through previous ALTER
          TABLE statements with the ATTACH clause.
 3
          Restart or terminate the previously failed LOAD operation on
          this table by issuing LOAD with the RESTART or TERMINATE option
          respectively.
 4
          Issue the LOAD QUERY command to check whether the table is in
          the process of being loaded. If yes, wait until the LOAD
          utility has completed, or if necessary, restart or terminate
          previously failed LOAD operation. If LOAD is currently not in
          progress, issue the SET INTEGRITY statement with the IMMEDIATE
          CHECKED option, to validate constraints in the newly loaded
          portion of the table.
 5
          Wait until the current LOAD operation has finished. You can use
          the LOAD QUERY command to monitor the progress of load.
 6
          Define a materialized query table using the MAINTAIN BY USER
          option. Then, use an INSERT statement with a subquery to
          populate the materialized query table.
 7

          Reorganize the table using the REORG TABLE command.

For a table in the reorg pending state, note that the following
          clauses are not allowed when reorganizing the table:
          *  The INPLACE REORG TABLE clause
          *  The ON DATA PARTITION clause for a partitioned table when
             table has nonpartitioned indexes defined on the table
 8
          Complete the unit of work, and re-issue the command.
 9
          If the REDISTRIBUTE utility is working, wait until it finishes
          working on the current table. You can use the LIST UTILITIES
          command to monitor the progress of the REDISTRIBUTE utility. If
          a previous REDISTRIBUTE operation failed and left the table in
          this state, issue the REDISTRIBUTE utility again with the
          CONTINUE or ABORT option and let it finish on this table.
 10
          Complete or cancel the table move operation and reissue the
          command. You can query the SYSTOOLS.ADMIN_MOVE_TABLE table for
          information about the status of the move operation.
