Customers running with DB2 10 NFM have noticed that table spaces associated with the DB2 directory data base or catalog (DSNDB01 and SPT01) experience significant space growth resulting from BIND/REBIND operations, DDL, utility activity (Reorg). The only way customer could sustain the issue was by frequently scheduling reorgs on the DB2 directory and catalog in DB2 10 NFM.

Customer X experienced problems after migrating to DB2 10 NFM. Selected packages where rebound right after the migration. PLANMGMT EXTEND as the default in V10 NFM, shouldallow to return to prior access path if needed.
However, for some packages the old access path could not be reverted even under PLANMGMT EXTENDED.
The reason behind this are Created Global Temp Tables (CGTT). They do have a dependency on SYSPKAGE . During ENFM, when SYSPKAGE is dropped, all packages containing CGTTs
When running a REBIND in DB2 10 NFM, REBIND will return an error message and no previous copy is stored.
Please refer to APAR PM81189 for further details on this problem.
