In a configuration where Optim™ Database Administrator or Data Studio is installed on a 64-bit version of a Windows operating system that also has a 64-bit DB2® for Linux, UNIX, and Windows data server that is V9.7 FP3 or earlier, DB2 commands and utilities cannot be run on that local DB2 database.
A similar problem may occur in this configuration when Optim Database Administrator or Data Studio runs the commands and utilities by using the DAS (DB2 Administration Server) on a remote DB2 data server. For more information, see Configuration for remote operations (http://publib.boulder.ibm.com/infocenter/idm/v2r2/index.jsp?topic=/com.ibm.datatools.base.install.doc/topics/c_dsa_remote.html)
The inability to run DB2 commands and utilities does not occur when the configuration is a 32-bit DB2 database with a 64-bit version of a Windows operating system, or when the operating system is Linux.
A 64-bit version of a Windows operating system where a 64-bit DB2 for Linux, UNIX, and Windows database V9.7 FP3 or earlier is installed.
Resolving the problem
Upgrade your DB2 for Linux, UNIX, and Windows database to V9.7 FP4 or later. See the available DB2 V9.7 fix packs in IBM Fix Central.
