Overview IMS is IBM's high-performance application and data server for IBM System z®. No other solution offers the combination of extremely high performance, scalability, rock-solid reliability, and runtime efficiency. When it comes to running core applications that are at the heart of business processing, most large corporations worldwide continue to depend on IMS. Today's Enterprise IT needs are more closely tied to the business than ever before. The business requires efficiency to meet the cost challenges and responsiveness demanded by the global economy. Enterprise IT must support growth, allowing the business to rapidly develop new products and services to remain competitive while at the same time increasing productivity and flexibility on demand. Business today IBM United States Software Announcement IBM is a registered trademark of International Business Machines Corporation 1 209-302 also requires IT systems to be resilient, helping reduce business risk and helping the business to comply with regulations and business processes. IMS and IMS tools continue to evolve to provide value and meet these needs for enterprise customers. They have provided investment protection for nearly four decades. IMS V11 provides unmatched capabilities to address your On Demand Business needs through enhanced integration, openness, manageability, and scalability. IMS V11 benefits: • Integration and open access improvements provide you with flexibility and support your business growth requirements. • Manageability enhancements optimize system staff productivity by improving ease-of-use and autonomic computing facilities, while also providing increased availability. • Scalability: IMS V11 delivers improvements to the well-known performance, efficiency, availability, and resilience of IMS by exploiting 64-bit storage. IMS V11 includes many additional features and improvements that along with the System z platform will help you meet your IT and enterprise data center cost challenges, as well as efficiency, resilience, and flexibility needs.

Key prerequisites IMS V11 can be used with all IBM processors capable of running z/OS® (5694-A01) V1.9, or later. Additional prerequisites exist for specific IMS V11 functions. Planned availability date October 30, 2009 Description Integrated/open access with new application development/connectivity IMS Open Database support IMS Open Database support enhances the distributed access to IMS data and the availability of IMS. This support extends the IMS Connect function as a gateway to IMS data, adding to earlier support for IMS applications and operations. This support provides a standards-based (J2EE, as well as JDBC) direct interface to IMS data from TCP/IP-enabled Windows®, Linux® for System z, and z/OS platforms. Access is provided with an IMS Universal DB Resource Adapter for J2EE runtime environments (for example, WebSphere® Application Server) as well as an IMS Universal JDBC driver and IMS Universal DLI driver for non-J2EE environments. It includes a new Common Service Layer address space for managing the connections through the IMS Open Database Access (ODBA) interface to IMS data. This allows an application to access an IMS database across LPAR boundaries rather than requiring that the application be in the same LPAR as the IMS database manager. The use of the new address space can reduce U113 abends in this environment. This support provides a scalable distributed data access solution, using a standards- IBM United States Software Announcement IBM is a registered trademark of International Business Machines Corporation 2 209-302 based application framework, providing connection pooling, security authentication in IMS Connect, and security authorization in ODBA. IMS Connect enhancements IMS Connect enhancements offer an optimized TCP/IP connectivity interface to IMS. These enhancements improve reliability, systems management, usability, serviceability, and the client connection process. They increase flexibility and improve diagnostics, error checking, and user-defined messages. They include configuration member support, enhanced commands, improved availability with a new recorder trace facility, new/modified messages, and new event records for the HWSTECLO exit. IMS Connect enhancements provide greater availability by reducing required restarts and the need for operator intervention. They allow customers to tailor KeepAlive processing by setting appropriate time values per port. This can help to clean up broken sessions in a more timely manner, eliminate Recorder Dataset full condition, and relieve operator interaction in re-establishing connections to TCP/IP after a session failure. • Enforcement of the single SSL port restriction helps prevent errors when attempting to use multiple SSL ports. This improves IMS Connect reliability when processing SSL client connections. • The User Message exit return without socket disconnect supports send back in the user message exit without termination and maintains socket connections for user message send back type flows, removing the burden of the client having to re- establish the connection. • Super Member on Datastore adds granularity to allow customers to choose which datastore instance within each IMS Connect is included for each Super Member. This eliminates the restriction that all defined data stores are part of the same Super Member group. • Message content enhancements identify a bad storage address to HWSP1410W, when it fails to release storage, which will be an aid to diagnostics. • TCP/IP KeepAlive support is provided at the port level. • The Port Message Edit Exit provides an exit to edit message between TCP/IP and IMS Connect. • VIEWHWS provides summary-level output and adds Datastore to the client display. • Generated Client ID support for the IMS Transaction Manager Resource Adapter generates the HWSxxxxx client ID if none is provided or if a duplicate is encountered. This avoids duplicate client errors when running many instances of the WebSphere Application Server with the Transaction Manager Resource Adapter due to duplicate client IDs generated by the IMS Transaction Manager Resource Adapter. This function was previously provided for IMS SOAP Gateway and clients who develop their own solution. • Recorder Trace is incorporated into the Base Primitive Environment (BPE) Trace. This improves the availability of this trace, avoiding data loss due to dataset full conditions, and provides more flexibility in defining, managing, and maintaining the trace dataset with little or no additional effort. • TCP/IP Auto Reconnect provides automatic reconnection when TCP/IP is cycled. • MAXSOC improvements include maintaining port-level socket count and overall socket count, issuing warning messages when the socket warning level is reached, and displaying current socket count on the VIEWHWS command output. • Commit Mode 0 (CM0) ACK Timeout allows Timeout Queue name at the Open Transaction Manager Access (OTMA) connection time. Support is also provided to extend the OTMA timeout function to cover the CM0 output messages so the TPIPE will not be left in the hang condition. This avoids the need to issue an IMS command to get out of the TPIPE hang condition caused by a missing timeout. This strengthens resiliency. Previously, if TPIPE sent a commit-then-send output and the client did not send an acknowledgement, the TPIPE could hang and cause many subsequent messages to be queued to the TPIPE. • Client ID uniqueness enforces client ID uniqueness across all TCP/IP ports of an IMS connect.
