DB2 V9 bug - REORG pending?
Hi All,
I am using "DB2 v9.1.0.2" in a development environemnt. Ever since we migrated to V9, I have seen tables in REORG pending frequently. I am not talking about issues related to "Reorg recommended" ALTER statements. Sometime changing a column from VARCHAR(5) to VARCHAR(10) can cause REORG pending. Sometimes it occurs without any DDL change.

Does anybod have the same experience? Is this a known bug of DB2 V9?

Thanks for you advice.

Do you have automatic maintenance enabled?

AUTO_MAINT = ON
AUTO_TBL_MAINT = OFF

Did you imply I needed to turn it on?

If it were enabled it could explain the situation. By the way,

_is_ a "Reorg recommended" ALTER statement, so no surprise here.

@n_i, you are correct. After altering column it is recommended to execute reorg because of performance benefits. DB2 places new data related to "altering column" to the end of pages. Not the best thing if huge number of rows are in table.

@DBA-Jr, try to reorg table. Has problem disappeared?
