DB2 FOR LUW / DB2FORLUW / A50 - DB2

After upgrading DB2 from an older release, ODBC SYSTEM DSNs will 
get removed from the system.  This only occurs when upgrading 
from one release to another (For example, v9.5 to v9.7), not 
Fixpacks within the same release.  This occurs because the act 
of upgrading releases uninstalls the old ODBC driver from the 
system then installs the new ODBC driver.  The ODBC driver 
uninstall act causes the SYSTEM ODBC DSNs to be removed. 
 
This APAR will allow the SYSTEM DSNs to be retained after 
upgrading.

upgrading.
