In order to upgrade to New DB2 Versions or Modes, use the following procedure :
Update the DB2 subsystem version (SSIDVER) and migration mode (SSIDMODE) on the SETUPXX parmlib member. The migration mode must be the same as the DB2 runtime environment.
Update the DB2 load library information.
Regenerate and execute the following DB2 catalog customization tasks:
. Compare DB2 objects.
. Create required DB2 objects.
. Bind product packages and plans
Moreover, ,after setting SSIDVER= V11 in your SETUPXX, you can check, using the TSO ISRDDN command from the DB2 Tools MAIN MENU, if the SDSNEXIT we are picking up is the one in SETUPXX.
Then on member DSNDHECP if you find either of the following: V11R1M0 or V10R1M0, you can verify the actual version.
