MY.DATASET(DB29%TST)). This
feature can save an enormous
amount of time and reduce errors.
In a multistep job, data sets
specified with OLD, MOD or NEW
are held until the completion of
the job. JCL and GRS support is
now available for dynamic ENQ
downgrade whereby a data set
will be changed to SHR after the
job's last OLD, MOD or NEW step.
This is accomplished by using
the new JES2 job class parameter
DSENQSHR or the new JOB
statement parameter DSENQSHR.
For batch jobs, once the last step
with an exclusive lock for a data
set is completed, the data set is
modified to share.
A PDSE member cannot
exceed 15,728,639 records.
The new limitation is more

than 125 times larger (about
2,146,435,071 records) than
previous versions and can be
substantially larger than the
maximum supported size of a
PDS member. At times, a PDS was
created instead of a PDSE. This
can now be resolved by using new
IGDSMSxx member parameter
HONOR_DSNTYPE_PDSE.
From time to time, a specific
management class is assigned
to a DB2 data set instead of null.
IDCAMS ALTER doesn't allow
a user to nullify a management
cw lass, but Interactive Storage
Management Facility (ISMF)
provides support to remove
the management class from a
data set. Users can now use
the IDCAMS ALTER function
similar to ISMF by specifying

'ALTER NULLIFY' to nullify a
management class.
Although Large Block Interface
(LBI) was introduced more than
a decade ago, users could not
use IDCAMS for LBI data sets.
However, users can now use
IDCAMS REPRO and PRINT.

Powerful Solutions
The next installment of this
article will describe new z/OS
V2.2 features for DB2. In z/OS
2.1, powerful enhancements
and solutions were introduced
that greatly help DB2 users. Most
aren't defaults and require the
client to make changes to
the environment. As you can see,
some real game changers are
available to make DB2 an even
better database solution.
