The DB2 workload consists of light to moderate transactions from two defined and
well-structured applications, inventory tracking and stock control.IMS/DC is used
as the transaction manager.The applications are functionally similar, but not
identical to, two of the IMS/DL1 and CICS applications.The DB2 contains seven
transactions. Conversational and wait-for-input transactions are not
included in the DB2 workload.
CICS work consists of light to moderate transactions from many of the same
applications mentioned for the IMS work.The CICS applications are written in
COBOL or Assembler and are functionally similar, but not identical, to the
applications used in the IMS workload and uses VSAM datasets only.There are
six sets of 17 unique
transactions, and five of these are run above the 16Meg line.
Note: When estimating MVS/DB2 or MVS/IMS for the a 43xx, 937x, or 9221
replacement, use the following approximations:
MVS/DB2 ==> .8 x VSE/CICS Light I/O (See “VSE/CICS Performance” on
MVS/IMS ==> .8 x VSE/CICS Light I/O (See “VSE/CICS Performance” on
