This IBM Redpaper publication examines performance when using different SOAP message sizes in CICS Web Services.
We used a preexisting basic Web Services environment with no message handlers or header handlers. Using WebSphere Studio Workload Simulator (WSWS), we ran a number of simulations using predefined scripts. For more information about WSWS, refer to WebSphere Studio Workload Simulator User’s Guide, SC31-6307. We then processed the CICS SMF data using CICS Performance Analyzer (CICS PA) and collated the statistics. For more information about CICSPA, see CICS Performance Analyzer User’s Guide, SC34-6307.
This paper also reviews a customer scenario, DanskeBank. We provide an overview of the bank’s ATM system, and briefly discuss the IFX framework. We detail our use of WebSphere Developer for zSeries (WD/z) to simulate request messages from an ATM, present a performance comparison between optimized and non-optimized schema versions, and cover schema versus container definitions, large fields, and schema complexity. Finally, we provide an example of the impact of mapping levels.
