DataDirect Adds zIIP to System z

Arthur Cole

Enterprises dealing with heavy transactional processing requirements for applications related to BI and ERP might get more mileage out of their System z mainframes with the newest version of DataDirect's Shadow data integration system, according to this write-up in ADTmag.


Shadow works with the System z9 Integration Information Processor (zIIP) and Application Assist Processor (zAAP) to free up computing capacity and enhance Java and XML apps.


The system is unique in its use of both the Task Control Block (TCB) and the System Request Block features in IBM's z OS. Using a hybrid TCB/SRB thread guide allows the system to divert workloads to the zIIP specialty engine, leaving the CPU to handle application and data processing.


Although the system is optimized for the DB2 database, it also supports mainframe data queries to IMS, VSAM, Adabas and IDMS, in addition to SOAP/XML parsing for Web services.
