Hi Sandeep...
I have a couple of links I open up once a month to check for software updates and patches:
In addition to Fred's link to the CMOD binaries, I frequently check for DB2 news:
http://www-01.ibm.com/software/data/db2/support/db2_9/If you organize these bookmarks into a single folder in a browser like Firefox or Safari, you can choose "Open all Links in Tabs" (by placing the folder in the Bookmark Bar, then right-clicking on the Folder name) and have all of the links load up in the background, then quickly see what's new and exciting in the world of CMOD.
Take care...
-JD.
