A New DB2 Manual

I'm just now getting around to downloading the recently refreshed IBM DB2 9 for z/OS manuals. IBM updated almost all of the DB2 manuals in December 2008. Indeed, 19 of the 24 manuals listed have a publication date of December 2008.

But wait, I haven't seen one of these manuals before: IRLM Messages and Codes for IMS and DB2 for z/OS. If you take a look at the manual, yes, it is a first edition.

This "new" manual describes messages and codes that are issued by the IRLM (internal resource lock manager) which is used by both IMS and DB2 for z/OS. The information is not necessarily new, though, as it was previously contained in the messages and codes publications for both IMS and DB2. But now, we have a single manual.

Another thing I noticed, but I'm not sure exactly when it happened, is that Directory of Subsystem Parameters has been removed as an Appendix of the DB2 Installation Guide (dsnigk15). Now I know this Appendix was there in this manual when DB2 9 first came out (I still have the PDF)... but it was not in the previous edition (dsnigk14) of the Installation Guide either. Anyone know if it was moved somewhere else (wouldn't make much sense since it refers back to pages in the Installation Guide)? Or if there are plans afoot to make a DSNZPARM manual (I've been requesting and wishing for that for years).
