Overview

With z/OS® V1.9, IBM plans to extend the value of the flagship mainframe operating system with improvements in all of its core competencies, including scalability, availability, and resource optimization. With increased focus on simplifying z/OS for IT professionals, plans for z/OS V1.9 include improvements to the IBM Health Checker for z/OS, the IBM Configuration Assistant for z/OS Communications Server, DFSMSrmm™, ISPF, Hardware Configuration Manager (HCM), and Coupling Facility services, as well as a new dbx GUI. Additional enhancements to z/OS are planned to make the operating system more powerful in applying centralized policy-based rules for defining and controlling how your applications behave.

Advancements in the z/OS Communications Server will help put the mainframe in a leadership position in terms of providing network solutions. With the planned ability to provide centralized policy services and policy-based routing (along with ability to apply security, intrusion detection/defense, qualities of service, as well as other features) z/OS can help you customize the network to suit the needs of your applications — doing this in a simplified, centralized, manageable, and auditable manner that is anticipated to be transparent to the application.

The z/OS Integrated Cryptographic Service Facility (ICSF) is planned to be enhanced to include the PKCS#11 standard. ICSF is the fundamental base of z/OS mainframe encryption which enables you to encrypt and decrypt data, generate and manage cryptographic keys, and perform other cryptographic functions dealing with data integrity and digital signatures. With adoption of the PKCS#11 standard, the strength of mainframe encryption and secure centralized key management can be brought to and used by Web-based application and networking environments more easily.

The z/OS Workload Manager (WLM) is planned to be enhanced with improved performance routing, priority settings, and cancel functionality, further improving on the mainframe's leadership position in workload management capabilities. With z/OS WLM, you can define business and performance goals customized for your applications. The z/OS system decides how much resource, such as CPU and storage, should be given to applications that serve the workload to meet the goal. WLM constantly monitors the system and adapts resource applications to meet application goals, taking into account not only server resources, but network traffic, router bottlenecks, application health, and transaction prioritization as well, thus providing autonomic, policy-based z/OS performance management that can be tuned to meet your applications' needs.

Previews provide insight into IBM plans and direction. Availability, prices, ordering information, and terms and conditions will be provided when the product is announced.

Daylight saving time: A provision of the U.S. Energy Policy Act of 2005 extends Daylight Saving Time (DST) by four weeks, beginning in 2007. This law moved up the beginning of Daylight Saving Time, to the second Sunday in March from the first Sunday in April. The return to Standard Time will be delayed a week, from the last Sunday in October to the first Sunday in November. In 2007, DST will begin on March 11 and end on November 4. Besides the United States, Canada, Bermuda and the Bahamas have also decided to adopt the same DST rule changes.

IBM has released updates to the z/OS operating system to support this change. APARs PK24076 and OA18692 provide the necessary changes to support the extended Daylight Saving Time rules for previous releases of the operating system. z/OS V1.9 includes these updates.

In addition, IBM has created a central Web site to provide information about every IBM product and how they may be affected by this DST change. Refer to

Compatibility

Coexistence and migration rules should be taken into account in planning future migrations. The z/OS coexistence, migration, and fallback policy aligns with the service policy. IBM intends to continue with the practice of providing service support for each release of z/OS for three years following its general availability (GA) date. In some cases, more than three releases may be coexistence, migration, and fallback supported if IBM, at its sole discretion, chooses to provide service support for greater than three years for a release. However, any z/OS release having three or fewer months of service remaining at the time of GA of a new release will not be coexistence, migration, and fallback supported.

Migration forward as well as fallback should be made within the same z/OS releases supported by the coexistence policy.

The following table shows the releases that are planned to be coexistence-supported with z/OS V1.9.

Coexistence-supported releases

Release       Coexistence-supported with release in Column 1
 
z/OS V1.9     z/OS V1.7, z/OS V1.8, z/OS V1.9
z/OS V1.10    z/OS V1.8, z/OS V1.9, z/OS V1.10
z/OS V1.11    z/OS V1.9, z/OS V1.10, z/OS V1.11
 
(1) Operating system levels beyond z/OS V1.9 represent
    current intentions of IBM.

This consistent coexistence, migration, and fallback policy applies to release migrations for all configurations, whether they are:

It is very important that you order the required z/OS release you need for migration and coexistence while it is still available. z/OS V1.7 was withdrawn from marketing effective October 23, 2006, but is still available via the CustomPac family fee-based offering, SystemPac®. Refer to information under Key dates to find out how long z/OS V1.7 will remain orderable via SystemPac.

For additional information on z/OS coexistence and release migration information, refer to z/OS Planning for Installation (GA22-7504) at

For migrations inside the IBM migration and coexistence policy, IBM Global Technology Services (GTS) has fee-based offerings that provide a PTF on demand service for toleration and coexistence maintenance based upon your SMP/E Consolidated Software Inventory (CSI). With these offerings, you specify the release of z/OS, z/OS.e, or other products, or hardware (for example, 2094) to which you are migrating, and all configured toleration/coexistence maintenance for your current system (as specified by your CSI) will be delivered to you as a customized package in electronic or physical format. This is provided through the S/390 SoftwareXcel offering, via the Service Request and Delivery (SRD) function.

GTS also provides hands-on fee-based services to assess whether a migration outside the migration and coexistence policy might be possible. For more information on the migration services that GTS provides for both inside and outside the migration and coexistence policy, contact your local IBM sales specialist.

Key dates

Installation and customization

IBM plans to update the Customized Offerings Driver (5655-M12) in the second quarter of 2007 to contain a subset of z/OS V1.7.

The IBM Migration Checker for z/OS is a new as-is tool available from the z/OS download Web page. It includes several batch programs you can run to help determine whether certain migration actions will be needed to migrate to z/OS V1.8 on the currently running system. This tool will not perform any migration actions on your system. It is intended to be used with the z/OS Migration book to help you create your migration plan.

Though the Migration Checker for z/OS is primarily intended to help with migrations from z/OS V1.7 to z/OS V1.8, some programs are expected to be useful for migrations from z/OS V1.7 and z/OS V1.8 to z/OS V1.9. Among others, the checks for the TN3270 server running in a separate address space, discontinuing the use of zFS multi-file system aggregates, checking for VSAM data sets with deprecated attributes, and checking the integrity of SMS control data sets should be useful for helping you plan migrations to z/OS V1.9.

CustomPac enhancements

SystemPac can help simplify HiperSockets software enablement support: SystemPac will provide sample configuration data for HiperSockets in the TCP/IP SAMPPROF member of the CPAC.PARMLIB data set. You can change the values as needed and add them to your TCP/IP profile. This is intended to help save you time when enabling HiperSockets. (Note: Other system and hardware changes are required to enable HiperSockets.)

SystemPac will be enhanced for encryption enablement for z/OS ICSF: After installing and activating your cryptographic hardware feature, to start ICSF for the first time, you can use the new SystemPac ISPF panels, procedures, and JCL to help you manage z/OS ICSF setup and startup. This includes:

This is intended to be useful for first time users of z/OS ICSF, and is designed to help simplify setup and startup tasks. Additional tasks are required to fully enable encryption.

SystemPac has extended ordering of z/OS V1.7: Support for z/OS V1.4 is planned to end in March 2007. You should be planning to migrate to z/OS V1.7 before this. Recently we have allowed SystemPac to have the previous z/OS release ordered after it was no longer available on ServerPac. We are doing the same for z/OS V1.7.

RefreshPac will provide enhanced preventive service maintenance options: To be in line with IBM's recommendations for installing preventive service, RefreshPac will be enhanced to provide an additional option, the Recommended Service Update (RSU) only service packages, in addition to the current combination of RSU and PUT levels.

When ordering an RSU only deliverable you will get a collection of PTFs identified with a SOURCEID of RSUyymm, where yy indicates the last two digits of the year and mm indicates the month. Additionally, HIPER and PE-fixing PTFs will be shipped along with a customized installation guide and installation dialog jobs to install the service. The APPLY job supplied will allow you to apply only those PTFs for RSUyymm without the HIPER/PE PTFs.

ServiceLink enhancements

Customized lists now available in the ASAP, AST, and ETR applications of ServiceLink: By accessing IBMLink™ and using the Automatic Software Alert Process (ASAP), Automatic Status Tracking (AST), and Electronic Technical Response (ETR) applications of ServiceLink, you will now be able to customize your notification lists, your tracking lists, the layout of your ETR records, and the list of ETR records for your account. You will be able to specify:

Your customized list layout will subsequently be used whenever the list is displayed, either in the current session or in a later session.

Additionally, ASAP notification e-mails will include a list of the APARs or PTFs for which notifications have been added to the notification list. For each APAR or PTF listed in your ASAP notification e-mail, the APAR or PTF number, product number, and product description will be included. AST notification e-mails will include a list of the APARs or PTFs that have been updated. For each APAR or PTF listed in your AST notification e-mail, the APAR or PTF number and reason for the notification will be included. The updated notification lists will help save you time so that you do not have to go back to the list and look at which product has been updated.

Service Request and Delivery (SRD) will provide enhanced preventive service maintenance options: The Order preventive service option of SRD will be enhanced to provide Recommended Service Update (RSU) only service packages, in addition to the current combination of RSU and PUT levels, to help you maintain a more stable and resilient system.

When ordering an RSU only deliverable you will get a collection of PTFs identified with a SOURCEID of RSUyymm, where yy indicates the last two digits of the year and mm indicates the month. Additionally, HIPER and PE-fixing PTFs will be shipped along with a customized installation guide and installation dialog jobs to install the service. The APPLY job supplied will allow you to apply only those PTFs for RSUyymm without the HIPER/PE PTFs.

Cross-component functional buckets are now available in SRD: You can now acquire up-to-date customized service recommendation lists (buckets) for selected functions with ServiceLink. These lists contain cross component functions which do not have a unique orderable component. Some examples are GRSSTAR (GRS Star mode), HC HECKER (Health Checker for z/OS), XRCSCA (Extended Remote Copy), ZAAP (zSeries Application Assist Processor), and ZIIP (z9 Integrated Information Processor).

You can order the list of orderable buckets by accessing "Order toleration/coexistence maintenance based on CSI profile" in the SRD application. The list of orderable buckets will keep changing, so be sure to check on them frequently.

SIS, AST, ETR, and SRD are included in the service offerings, SoftwareXcel Enterprise Edition for zSeries, SoftwareXcel Basic Edition, and Resolve. ASAP is included in SoftwareXcel Enterprise Edition for zSeries and Alert.
