Status Not under consideration
Workspace Db2
Created by Guest
Created on Jan 8, 2015

DB2 to add support for alter table without going on need for reorg immediately and allow full access (read,write,alter...etc)

After setting compatibility vector to ORA, we expect alter table to not affect read/write access. In our test, we see that after dropping even a single column, table goes in reorg_pending = Y status and we can not use reorg inplace to continue insert/update/delete rows from the table unless offline reorg is explicitly called.

Offline reorg blocks table for any DDL/DML operation and that results in server error for application users.

In summary, we need to have alter table not affecting any DDL/DML operation same as Oracle.
