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 Linux, UNIX, and Windows database V9.7 FP3 or earlier is installed.
Resolving the problem
Upgrade your DB2 Linux, UNIX, and Windows database to V9.7 FP4 or later.
