The new -storagegroups parameter has
been added in support of storage groups. Also, the output report for
the -catalogcache, -hadr, -serviceclasses, -storagepaths, -tablespaces, -tcbstats, -workclasssets,
and parameters have changed to support new functionality.
Details
In Version 10.1,
the new -storagegroups parameter provides details
about storage groups and storage paths. If you do not specify a storage
group identifier, information about all storage groups is reported.
The -storagepaths parameter continues to report
information about all storage groups.
Also, the output reports
for the following parameters have been changed:
- The -catalogcache parameter output reports
details about the new table space cache.
- The -hadr parameter
output has been completely changed. Existing fields have been renamed
to match the output from the new MON_GET_HADR table function, and
fields have been added to support monitoring for the new HADR multiple
standby. The formatting of the output has also changed from multiple
field names on one line and field values on the subsequent line to
having one field per line.
- The serviceclasses parameter
output now includes the UOW throughput, activity throughput, activity
lifetime average, CPU Velocity, and CPU Utilization.
- The -storagepaths parameter
output includes storage group configuration details.
- The -tablespaces parameter output now includes
the storage group identifier that a table space is associated with
and table space storage statistics.
- The -tcbstats parameter
output for the RowsComp and RowsUNcomp columns has been removed. Also,
the output for the column and data for IndexObjSize has been deprecated.
If you perform a reorganization to reclaim extents, the IndexObjSize
output does not accurately reflect the number of pages in the index
object because the value still includes the pages that were released
during the reorganization. You should use instead the INDEX_OBJECT_P_SIZE
or INDEX_OBJECT_L_SIZE columns of the ADMIN_GET_INDEX_INFO table function
to obtain accurate values.
- The -workclasssets parameter output is no
longer in a table format. The output format lists basic work class
information followed by the work class attribute information.
Resolution
Change applications or scripts
that use the output of the db2pd command to adjust
to these changes.
Start using SQL administrative routines and
views that report the same information instead of the command output
as they offer more flexibility for programming.
