32 The IBM z/os Communications Server TCP/IP Implementation series provides understandable, step-by-step guidance about how to enable the most commonly used and important functions of z/os Communications Server TCP/IP. 31

33 This book provides a technical introduction to many of the concepts surrounding Liberty, including Java Enterprise Edition (Java EE) and the web profile. It then describes the steps necessary to develop, configure, and deploy web applications into the Liberty server within IBM CICS. Liberty is a modular implementation (or profile) of WebSphere Application Server technology. It is intended to provide a lighter weight and more dynamic runtime than the classic WebSphere Application Server runtime. 32

34 This book was written to demonstrate the capabilities of IBM OMEGAMON for JVM on z/os. The product was installed in a test environment on several JVMs, both stand-alone and in subsystems like CICS and IMS. Some of these JVMs were poorly configured or allowed to use inappropriate defaults in order to use OMEGAMON to expose these problematic configurations. Some applications were also written with flaws that might be found in Java programs that adversely affect performance, to the same end. 33

35 This IBM Redbooks publication helps you install, customize, and configure an IBM z13 and build z/os environments. This book is intended for those readers who are new to the platform and are faced with the task of installing a mainframe for the first time. By the term mainframe in this instance, we refer to the hardware and the system software. The intention is to show you how this installation can be done. Volume 1 shows you how we set up a mainframe and installed z/os V2R2 and IBM DB2 V11. The starting point is a basic hardware configuration of an IBM z13 and DS8000 as shipped from the factory. Volume 1 also shows you how the following milestones were achieved: - Creating a configuration for the Customized Offering Driver (COD) system - Stand-alone restoration of the COD - Expanding the configuration - Installing the z/os V2R2 ServerPac - Loading and running IVPs for z/os ServerPac - Installing DB2 ServerPac and IVPs 34

36 This paper describes the performance implications of increasing memory in the following areas: - DB2 buffer pools - DB2 tuning - IBM Cognos Dynamic Cubes - MDM with larger DB2 buffer pools - Java heaps and Garbage Collection tuning and Java large page use - IBM MQ v8 64-bit buffer pool tuning - Enabling more in-memory use by IBM CICS without paging - TCP/IP FTP - DFSort I/O reduction - Fixed pages and fixed large pages 35

37 MT-PPRC provides the capability to have two PPRC relationships on a single primary volume. With this enhancement, there can be another target available to provide additional data protection to act as a backup if a disaster occurs. 36

39 This release contains new functionality to handle arrived messages: delete possibilities are extended and unread messages functionality is added. In addition, new keywords for notifications categories are supported, namely error, warn, info and action. Besides, mute notifications feature is introduced: now it is possible to turn on the mute mode on a server in order not to be disturbed by new notifications. This release includes general bug fixes as well. 38

40 This release includes the following new features: Messages of these products and releases were added: z/vse, Tivoli Storage Manager, Tivoli Advanced Allocation Management, and Automatic Binary Optimizer for z/os V1.2 Miscellaneous updates and fixes to links, keyboards, and menus 39

42 HZR: GRS blockers and latch Runtime Diagnostics capabilities and diagnostics are planned to be improved and enhanced by following the blockers of enqueue contention and GRS latch contention across a sysplex to find the source of the contention and detect deadlocks between these resources sysplex-wide. RLS to replace AIX upgrade lock DFSMSdfp VSAM record-level sharing (RLS) is designed to replace the existing alternate index (AIX) upgrade lock with record locks and redo processing to keep the upgrade set and the base cluster in sync for update requests without forcing the updates to be single threaded. Allowing concurrent AIX updates is intended to improve performance, most notably when updating numerous large records with many alternate keys. R/O access to PPRC secondaries FSMSdfp SAM and VSAM enhancements are planned to provide read-only access to data sets that reside on Peerto-Peer Remote Copy (PPRC) secondary volumes. Certain applications can take advantage of redundant hardware and avoid interference with production work. TSO 8 Characters Userid New support is planned to be added to allow TSO/E user IDs to be eight characters long. Extended PDS stats Support for PDS member extended statistics in ISPF is planned to be improved. ISPF will be designed to automatically generate extended statistics for a PDS member when at least one of the line count values for the member exceeds Logger staging support >4GB In z/os V2.3, an enhancement to z/os system logger is planned to allow log stream staging data sets to be allocated greater than 4 gigabytes CPACF: policy based data protection/encryption z/os 2.3 will be designed to provide policy-enabled data protection for z/os data sets, zfs file systems, and Coupling Facility structures, giving users the ability to encrypt data to strengthen compliance and audit responsiveness and provide simplified security processes and protection for mission-critical dat 41

43 PKI Services to detect DB2 unavailability PKI Services is planned to detect the unavailability of DB2 and provide notification. At a client's choice, PKI Services will either shut down when DB2 is not available or will be able to wait for a customer-specified period for DB2 to become available. This capability is intended to help reduce the volume of errors recorded in the job log. More simultaneous IPSec tunnels z/os 2.3 will be designed to increase capacity for simultaneous IPSec tunnels in a sysplex by increasing the amount of sysplex-wide security association data that can be stored in the EZBDVIPA coupling facility structure, allowing up to 16,384 lists to be configured. Shared Memory Communications Direct Memory Access (SMC-D) z/os V2.3 is planned to provide new support for fast, low-latency TCP/IP traffic between LPARs within a CEC using the Shared Memory Communications Direct Memory Access (SMC-D) software protocol over firmware-provided Internal Shared Memory (ISM) devices. Improved user control of the default VTAM Internal Trace (VIT) options Previously, a set of VIT options (API, PIU, SSCP, NRM, MSG, and CIO) were always active and could not be disabled. The VITCTRL start option will allow the enablement of a new "VIT Control" mode that provides the user with the capability of enabling and disabling any VIT option independently. While this capability is provided, it continues to be IBM's recommendation that the standard VIT options remain enabled to provide first-failure data capture capability for problem diagnosis. 42

44 USS /global directory A new directory called /global in the sysplex root is planned to be introduced in z/os V2.3. This new directory can be used by clients as a mount point for a file system that could contain files whose content needs to be consistent across the multiple systems of the sysplex or as a convenient location to provide a view of multiple levels of program products (not shipped as part of z/os), even though the product may be installed on only one member of the sysplex. This will not change where program products are installed. zfs salvage on the fly zfs is planned to provide the ability for a system programmer, with appropriate authority, to initiate an online salvage of a zfs aggregate in order to repair a damaged file system while the file system is still mounted. zedc for zfs individual files Enhancements to zfs file systems are designed to allow individual files to be compressed utilizing the zedc compression card technology. Existing file systems can be compressed while in use. This is not limited to new zfs file systems, and existing file systems can be eligible for compression also. zfs mount dynamic RWSHARE/NORWSHARE z/os V2.3 is planned to allow dynamic change of aggregate attributes for zfs so common MOUNT options can be changed dynamically without the overhead of unmounting and remounting the file system. Also, plans are to allow changing sysplex sharing status (RWSHARE/NORWSHARE) dynamically. UID(0) mapping according to BPXPRMxx SUPERUSER(x) When RACF is invoked to map UID(0) to a user ID, it is planned to return the same value defined in the SUPERUSER(x) keyword of BPXPRMxx. This will provide a consistent mapping to the user ID owning an object, such as a file or directory, as displayed by the 'ls -l' command. 43

45 Absolute MSU capping - WLM sensitive to capping before it starts z/os Workload Management (WLM) is planned to be enhanced with an option to cap a system to the MSU value that is specified as the soft cap limit regardless of the four-hour rolling average consumption. WLM real storage limit for service classes WLM resource groups are planned to be enhanced to limit the amount of real storage that may be used by the associated service classes. WLM to block eg. ZIIP code on CP z/os Workload Management will be designed to provide a control that allows service classes to be defined such that their specialty processor eligible work will not execute on general purpose processors. More zfs SMF logging in record 92 zfs will be designed to allow for the monitoring of important events in the SystemManagement Facility (SMF). Examples of such events are dynamic growing of an aggregate and disablement of an aggregate. zfs will use record type 92, which is also used by z/os UNIX System Services. In addition, general performance indicators, that is, the information that is currently shown in various MODIFY ZFS,QUERY operator commands, can also be stored. This will allow the ability to look back in time at the performance of zfs on the system. High Frequency Throughput Statistics (HFTS) New z/os support for High Frequency Throughput Statistics (HFTS) is planned to be provided to support a new SMF 98 record with an interval length in seconds to highlight workload inefficiencies before experiencing the consequences. 44

46 Workflow editor z/os V2.3 plans to add a new workflow editor to z/osmf to enable you to edit workflow in the UI instead of directly editing XML files. z/osmf PDS(E) attachments An enhancement is planned for PDSE attachment in the incident log application to support a member of PDS and PDSE as an attachment and support entire PDS or PDSE as an attachment. REXX support for workflows The z/osmf workflow engine is planned to be updated to support immediate REXX and script execution, as well as configurable job card information. 45

48 Display microcode bundle if returned by HW GDPS will display, when returned by the disk subsystem, the microcode bundle information on the Disk Subsystem List panel accessed from Option 31 - DSS list from the SSID pairs panel VPCPQSTC GDPS can now activate a new LOGR CDS configuration from controlling system even when the CDS is not activated there (cmd routing) Handling of the System Logger (LOGR) Couple Data Set (CDS) configuration, when excluded from GDPS management, has been enhanced. GDPS can now activate a new LOGR CDS configuration from a Controlling system, even when the LOGR CDS is not allocated in that system. The commands required are routed to a system where the LOGR CDS is allocated. This allows all CDS types to be configured from a single point of control. Performance optimization of Netview functions Shorter User impact Improved panel response Less cpu for monitoring GDPS has optimized its use of NetView functions, and other internal processing, to deliver improved performance for key code paths, particularly in large configurations. Beneficial effects can be seen several areas such as shorter User Impact Time, improved panel display response, and reduced CPU utilization during monitoring. 47

49 Prevents Storage controller health events message flooding GDPS handling of Storage Controller Health Events has been changed to prevent potential message flooding conditions. Improved communication of critical status info with cross memory services GDPS communication of critical status information has been improved through the use of high-reliability z/os cross memory services. NetView Web Application-based GUI sunset The NetView Web Application-based GDPS graphical interface is no longer supported. You can use the Websphere Application Server-based GDPS GUI which was introduced in GDPS SDF alert if device cannot be varied online IEF359I RESERVED OR BROKEN DASD DEVICE dev NOT VARIED ONLINE 48

50 Non-disruptive statesave (NDSS) if many IOS071I MASTER START PENDING To aid in problem determination for possible control unit problems, GDPS will take a non-disruptive statesave (NDSS) when a significant number of IOS071I (MASTER START PENDING) messages are received for a GDPSmanaged device. 49
