Provide Db2 utility messages regarding the usage (or not) of the Large Block Interface

The Large Block Interface (LBI) provided by z/OS can be used by Db2 utilities (such as COPY) to greatly reduce the utility runtime of when creating data sets on tape devices. The LBI must first be enabled through the DEVSUPxx member of SYS1.PARMLIB. The Db2 DBA can then specify the new BLKSZLIM keyword in the TEMPLATE utility to cause a Db2 utility to use the LBI when writing a data set to tape. However, there are currently no messages being written to the utility SYSPRINT data set to indicate whether Db2 is actually using the LBI or not. For example, if the BLKSZLIM keyword in the TEMPLATE utility but the DEVSUPxx member in PARMLIB was never updated to enable LBI in the LPAR in the first place, then Db2 must ignore the BLKSZLIM keyword and cannot create a data set using LBI. A message should be written to SYSPRINT of the Db2 utility to make the user aware of this. Conversely, if LBI is enabled on z/OS and the BLKSZLIM keyword is specified in the TEMPLATE utility, then a message should be written to the utility SYSPRINT to confirm to the user that LBI is indeed being used.


These messages would be most helpful as there is currently no way to easily determine if a dataset on tape was created using LBI.
