Inside IBM

z/OS DB2 TOOLS

Easily overshadowed by the announcement of eServer zSeries (100-322, 200-352, 200-358), three weeks later, on Sept. 12, 2000, IBM entered the z/OS database tools market (200- 298 to 302). Today, industry analysts peg IBM as DB2 tools market leader with 40 percent market share. Analysts’ opinions range from “good enough” to better than the competition, though they all agree that very complex database environments may need to look elsewhere.

DB2 Archive Log Accelerator (203-164) is the new name for the DB2 Archive Log Compression Tool. It combines data striping and DFSMS compression, and can output up to four copies of the compressed archive logs. The bundle known as DB2 Content Manager Complete Enterprise Option (CEO) (203-154) now includes DB2 Records Manager (203-077); DB2 ImagePlus Client Access for z/OS (200-259) has long been a component. End of Support (EOS) has been extended for several DB2 tools, including three bundles of DB2 Utilities 7.1 (203-142).

IMS TOOLS

The big news is for IMS tools (203-164). The new IMS Problem Investigator improves problem determination for both IMS Transaction Manager (TM) and IMS DB by automating many of the processes as well as including navigation aids, formatted and personalized reporting, and investigative procedures for IMS log data. Both an ISPF dialog and a batch reporting utility are provided. Also new, the IMS Multi-Dialog Manager uses standard IMS Exits to provide one PF key switching between sessions. It complements the existing IMS TM support for conversational transactions by managing the process of holding and resuming conversations for the end user.

There are still more tools to come, including a Performance Monitor (PM) and Online Reorganization Facility. IMS PM will provide, on a single monitoring station, real-time status monitoring and alerts for one or more active IMS subsystems, even across a Sysplex. This complements IMS Performance Analyzer’s batch reporting of IMS log and monitor data. The IMS Online Reorganization Facility will operate as a Batch Message Program (BMP), allowing database updates to continue during a reorg. These updates are also stored in a data space and applied to the reorged copy of the database as the last step of the reorg process.

Meanwhile, Version 2 of IMS Online Recovery Service has a new name: IMS Database Recovery Facility. It can now be started online or in z/OS batch even when IMS is not active, as it does not use IMS region resources to update the database. There is also extensive parallel and concurrent processing, analysis of recovery execution, and reporting of all open units of work that contain updates not applied in a point-in-time recovery. Finally, if you were waiting for the IMS TM Environment Support PTF for IBM File Manager 3.1 (202-197), it has been postponed (203-155).

MAINFRAME LINUX OPTIONS

Now that IBM owns Informix, it can run on zSeries Linux (203-149); specifically, Informix Dynamic Server (IDS) 9.4, Informix Client SDK 2.81, Informix Connect Runtime 2.81, Informix Server Administrator 1.5, Informix 4GL 7.32, and Informix SQL 7.32.

The 3584 tape library (103-171) has been expanded to support 16 frames, 192 Linear-Tape Open (LTO) Ultrium tape drives, 6881 cartridges and 1376TB (uncompressed). It provides SCSI High Voltage Differential (HVD), SCSI Low Voltage Differential (LVD), and Fibre Channel interfaces to zSeries Linux, iSeries, pSeries, xSeries, Sun, Hewlett-Packard, and other systems.

TIVOLI

Tivoli Workload Scheduler (TWS) 8.2 (203-159) is four related products that manage the production workload, not just batch jobs. Though priced differently, TWS for z/OS and TWS Host Edition are essentially the same product, formerly known as Tivoli Operations and Planning (OPC), but with many new features. Known simply as TWS, the third product runs on zSeries SuSE and Red Hat Linux, as well as Windows NT 4.0/2000/XP, AIX, Solaris, HP-UX, and nonmainframe Linux. Fault Tolerant Agents (FTAs), formerly known as OPC Tracker Agents, also run on Sequent DYNIX, OS/400, Windows Terminal Server Client, Compaq Tru64, and SGI Irix. TWS for Applications integrates TWS with Oracle e-Business Suite, PeopleSoft, SAP R/3, and SAP Business Warehouse.

Tivoli Configuration Manager (CM) for Automated Teller Machines (ATMs) 2.1 (203-160) manages and deploys software and data to the self-service ATMs typically used by bank customers. It runs on both Red Hat and SuSE Linux, on the mainframe and elsewhere, as well as on AIX, Solaris, HP-UX, and Windows NT 4.0/2000 Server; clients (not the ATMs) must be Windows NT 4.0/2000/XP workstations.
