Notes: Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here. IBM hardware products are manufactured from new parts, or new and serviceable used parts. Regardless, our warranty terms apply. All customer examples cited or described in this presentation are presented as illustrations of the manner in which some customers have used IBM products and the results they may have achieved. Actual environmental costs and performance characteristics will vary depending on individual customer configurations and conditions. This publication was produced in the United States. IBM may not offer the products, services or features discussed in this document in other countries, and the information may be subject to change without notice. Consult your local IBM business contact for information on the product or services available in your area. All statements regarding IBM's future direction and intent are subject to change or withdrawal without notice, and represent goals and objectives only. Information about non-ibm products is obtained from the manufacturers of those products or their published announcements. IBM has not tested those products and cannot confirm the performance, compatibility, or any other claims related to non-ibm products. Questions on the capabilities of non-ibm products should be addressed to the suppliers of those products. Prices subject to change without notice.

3 Notice Regarding Specialty Engines (e.g., ziips, zaaps and IFLs): Any information contained in this document regarding Specialty Engines ("SEs") and SE eligible workloads provides only general descriptions of the types and portions of workloads that are eligible for execution on Specialty Engines (e.g., ziips, zaaps, and IFLs). IBM authorizes customers to use IBM SE only to execute the processing of Eligible Workloads of specific Programs expressly authorized by IBM as specified in the Authorized Use Table for IBM Machines provided at ( AUT ). No other workload processing is authorized for execution on an SE. IBM offers SEs at a lower price than General Processors/Central Processors because customers are authorized to use SEs only to process certain types and/or amounts of workloads as specified by IBM in the AUT.

4 Connectors - Introduction The Connectors started as a single function in VSE/ESA 2.5 Since then, it evolved over time Its now more a technology than just a function consisting of many different features and functions supporting various connector solutions VSE/ESA 2.5 VSE/ESA 2.6 VSE/ESA Java-based Connector VSE Connector & Client J2C Resource Adapter for WAS SOAP/Web Services support VSE as Web Service provider or consumer VSE Script Connector non-java access to VSE programs and data Enhancements for VSAM Redirector VSAM Capture Exit New DBHandler supports normalization Added TSM support for VTAPE Fast Path to Linux on System z (LFP) In z/vm environment Enhancements of existing Connectors IPv6/VSE Stack IPv6 support in connectors Stacking Tape Support REST Engine SOAP Engine supports C&C DBCLI Enhancements VSAM Redirector Real-time synchronization of VSAM data with a database JDBC Driver for VSAM SQL based access to VSAM data Part of the Java-based Connector VTAPE Support Misc enhancements of existing Connectors SOAP/Web Services security Transport Layer Security Message Layer Security LDAP Sign-on support Signon using long, corporate user-id Authenticate against an LFDAP server Fast Path to Linux on System z (LFP) In LPAR environment IPv6 support in LFP z/vm IP Assist (VIA) Database Connector (DBCLI) Channels & Containers support in CICS TS 2.1 MQ Client Trigger Monitor Remote Debug Interface (as BETA)

14 6.2: RESTful Web Services support Use REST (Representational State Transfer) with CICS applications Provide existing CICS applications as RESTful Web Service to the outside world as the REST server Use/call external RESTFul Web Services from within CICS applications as the REST client Payload can be: JSON (JavaScript Object Notation) XML Plain text Binary Form fields Multipart Remote platform RESTful Web Service (HTTP) CICS Web Support CICS Transaction VSE REST Engine JSON Parser XML Parser CICS Application

15 What is REST (Representational State Transfer)? Representational State Transfer (REST) is a software architecture style consisting of guidelines and best practices for creating web services REST has gained widespread acceptance across the web as a simpler alternative to SOAP and WSDL-based web services RESTful systems typically communicate over the Hypertext Transfer Protocol (HTTP) with the same HTTP verbs (GET, POST, PUT, DELETE, and so on) used by web browsers The payload (message) transported by RESTful web services can be of various types (content types) Commonly used is JSON as well as XML, but it can also be plain text, or even binary data A RESTful web service typically operates on a certain 'object' on a server The object is typically addressed through the URI (part of the URL), for example Actions on such resources are typically denoted by the HTTP request types: GET would typically read the resource PUT would typically update/replace the resource POST would typically create the resource DELETE would typically delete the resource RESTful web services are typically stateless Each request from any client contains all the information necessary to service the request The session state is therefore held in the client As denoted by the term 'typically' in above descriptions, there is no hard requirement for any of the described properties

23 SNMP Monitoring Agent support Monitoring Agent enables customers to monitor systems using standard monitoring interfaces (SNMP V1) Available since V4.3 It also includes an open interface, which enables customers or vendors to use own programs (plugins) to collect additional data Data collected by the IBM provided plugins contains Information about the environment (e.g. Processor, LPAR and z/vm information) Number of partitions (static, dynamic, total, maximum) Partition priorities Number of CPUs (active, stopped, quiced) Paging (page ins, page outs) Performance counters overall and per CPU CPU address and status CPU time, NP time, spin time, allbound time Number of SVCs and dispatcher cycles Plugin interface allows Vendors to provide additional monitoring data
