The new eserver zSeries 990 (z990) (103-142) comes in four models: A08, B16, C24, and D32. The two digits in the model number indicate the maximum number of processors; multiply that number by 8GB and you have the maximum memory size; multiply that number by 1.5 and you have the number of Self-Timed Interconnect (STI) host buses. The minimum for all models is one processor and 8GB. The processors are based on CMOS9S-SOI technology, and are 50 percent faster according to IBM’s Internal Throughput Rate Ratios (ITRRs). New maximums are 30 LPARs (double z900), 512 channels (double), and 16 HiperSockets (quadruple). Planned: 60 LPARs, 1,024 channels, and IPL from Fibre Channel Protocol (FCP)-attached disks. The Integrated Cluster Bus-4 (ICB-4) is more than twice as fast as the ICB-3. Additionally, on every processor there are now three cryptographic options, including the new CP Assist for Cryptographic Function (CPACF).
The z990 and z/VM 4.4 (203-128) expand the QDIO architecture to provide adapter interrupts for OSA-Express and FCP channels, benefiting all pageable (V=V) guests, including Linux. z/VM 4.4 expands virtualization and improves the CP scheduler, increasing the number of concurrent guests, especially on larger n-way servers. This is the last release to support non-zSeries systems, and the RTM and PRF features, which have been replaced by the Performance Toolkit for VM. C/C++ (203-129) adds z/VM to its existing z/OS, AIX, pSeries Linux, and OS/400 platforms.
z/OS, SMP/E 3.2, and VWLC
Enhancements to last September’s Version 1.4 of z/OS (203-131) and z/OS.e (203-132) have just been announced; most are already available. DFSMStvs (Transactional VSAM Services) allows batch jobs and CICS online transactions to concurrently update shared VSAM data sets. Health Checker for z/OS and Sysplex is one of several additions to z/OS msys for Operations. The first phase of the IBM Consoles strategy, to enhance the operator messaging architecture, will be available early next year. Stolen from early 2004’s z/OS 1.5: Enterprise Identity Mapping (EIM) via APAR OW57137; and DFSMSrmm enhancements with APAR OW56584, also available for z/OS 1.3.
More features also have been added to z/OS 1.5. DFSMShsm volume-level Fast Replication will backup using Enterprise Storage Server (ESS) FlashCopy and RAMAC Virtual Array (RVA) virtual concurrent copy; it will also form the heart of a simple backup/recovery tool for DB2 Version 8. BookManager BookServer will be overhauled and renamed Library Server. RMF will gain RACF protection. In addition, there are Workload Manager (WLM) enhancements.
Version 3.2 (203-125) is the second stand-alone release of SMP/E, allowing sites to upgrade SMP/E without upgrading z/OS, z/OS.e, or OS/390 2.10. A new LINK LMODS command replaces REPORT CALLLIBS. Additionally, SMPLTS space requirements have been reduced.
Variable Workload License Charge (VWLC) (203-130) now has a lower base charge, three Millions of Service Units (MSUs) instead of 45, for z990, z900, and soon for z800.
Tivoli , Web Sphere, and Infoprint
Tivoli Storage Manager (TSM) 5.2 (203-091) allows the backup of snapshots and open files, and direct “LAN-free” data transfer to/from a SAN. The log collector engine of Tivoli Decision Support 1.6.0 (203-086) uses the Tivoli Data Warehouse format to store data accessible to products such as Tivoli Service Level Advisor; a data dictionary correlates with SMF records. Tivoli Access Manager for Business Integration Host Edition (AMBIHE) 4.1 (203-098) now supports WebSphere MQ (WMQ) Integrator, WMQ Integrator Broker, and IMS applications. Tivoli Monitoring for Web Infrastructure 5.1.1 (203-103) adds z/OS to the platforms where it can manage and monitor WebSphere Application Server components. Version 5 of WebSphere Application Server for z/OS (203-094) supports J2EE 1.3. Infoprint 4000 and 4100 (103-090) now support Gigabit Ethernet TX. Infoprint Xerox Transform (XT) Extender for z/OS (203-070) converts Xerox format output to AFP.
DB2 QMF 8 and OLAP Server 8.1
DB2 QMF (203-133) now has four components: QMF High Performance Option (HPO), QMF for TSO/CICS, QMF for Windows, and QMF for WebSphere. Version 8 includes OLAP with DB2 Cube Views, executive dashboards, and drag-and-drop queries and analytics. Based on Hyperion Essbase 6.5.1, DB2 OLAP Server (203-075) runs on z/OS Unix System Services (USSes) and includes OLAP Server Miner. Version 8.1 no longer uses the VSAM/Media Manager, allows the metadata catalog to be shared, and adds significant parallelism, hybrid analysis, and wildcard searches for table names.
