DB2 10 compatibility mode

Changes to the STRING formating of decimal data within the CHAR and VARCHAR built-in function and to the CAST specification with CHAR and VARCHAR result types as well as UNSUPPORTED TIMESTAMP STRINGs.

Reason for the changes in DB2 10 – SQL standards compliance

How many applications are affected by the changes?

Temporary solution for the problem until the affected applications are identified: ZPARM=BIF_COMPATIBILITY=V9_DECIMAL_VARCHAR

Initial situation

Methodology at customers site

To get all relevant applications (daily,weekly etc.) since mid of April 2014 a performance trace with IFCID 366 was run in production

For packages with static SQL additionally IFCID 63 was activated

Identified were 18 programs 1 Cobol Program (Static SQL) 1 C++ Program (Dynamic SQL) 3rd party 4 Java Programs (Dynamic SQL) 12 High Performance Unloads (Dynamic SQL)

Evaluation of trace records

Evaluation of SMF records with the help of

BMC Mainview also offers reporting capabilities described in the „Performance Reporter User Guide“

The BMC Datacollector has to be active Attention: Depending on the frequency of program calls space requirements for the SMF records increase drastically

SQL WorkloadExpert (WLX) for DB2 z/OS The SQL WorkloadExpert architecture comes in two parts

Mainframe DB2 Workload collector and processing

engine

Workstation analysis and reporting engine

DSC and SSC were selected and the data is stored in WLX tables

Processing and display of the data in Datastudio 4.1.1 or Eclipse on the workstation

What we have learnt

In contrast to the previously performed examinations using Omegamon, with WLX you need not collect SMF data for more than 12 months before the migration and analyze them.

With WLX you do not even need SMF data. The WLX straight-forward approach saves enormous time, manpower, and storage.

“Where is the BIF?” Is answered directly and the SQL is categorized and shown – Even for dynamic SQL you get the entire SQL text displayed.
