IBM Tivoli Allocation Optimizer for z/OS V1.1 is designed around the concept that any job in a z/OS environment can be susceptible to B37, D37, and E37 abends. These are all space-related issues that can occur during systems managed storage (SMS) and non-SMS data set allocation or over time as data sets grow during extend processing. If not controlled, these X37 type abends can result in task failure and decreases in productivity and data availability.
The vehicle typically used to drive data set allocation in a z/OS system is job control language (JCL). JCL determines the data set's initial size, its ability to grow, its ability to span volumes, and so on. It can be very difficult to match the needs of the data set with appropriate allocation parameters, particularly in light of growth and unexpected demand. Often, JCL is copied from one application to another even though both applications may generate significantly different quantities of data.
Each abend can be the result of slightly different circumstances. When any of these abends occur, IBM Tivoli Allocation Optimizer for z/OS V1.1 can help determine the nature of the current abend in process, make appropriate changes to the allocation parameters currently in use, and then retry the allocation (or extend) to help achieve success.
In addition, IBM Tivoli Allocation Optimizer for z/OS V1.1 can proactively release unused space when a data set is closed which can result in more available space for new allocations and data set extends. This can help prevent X37 type abends by keeping as much free space available as possible.
IBM Tivoli Allocation Optimizer for z/OS V1.1 can help overcome some of the limitations of SMS functionality and provide complementary functionality. SMS does not handle all situations in preventing space-related storage problems and does not provide as much flexibility as needed in the way they are handled.
SMS provides allocation recovery only for new data set allocations and extends on new volumes. Furthermore, SMS recovery options can be biased toward the addition of new volumes or increased fragmentation of the data set. The implementation of volume recovery under SMS tends to consume either catalog space or internal control block storage, both valuable commodities and potentially limiting factors for you.
You may have valid business reasons why SMS may not be fully implemented in your environment. In this scenario, IBM Tivoli Allocation Optimizer for z/OS V1.1 can provide significant benefits by helping to avoid the fear, uncertainty, and doubt that can exist in your environment when you know that non-SMS managed data sets are not totally protected and the most susceptible to abending.
The following features of IBM Tivoli Allocation Optimizer for z/OS V1.1 help overcome related limitations:
- Most unsuccessful Direct Access Storage Device (DASD) allocations are eligible for recovery (with the exception of certain system data sets).
- Maximum use of the current volume can be obtained before an attempt is made to allocate additional volumes.
- Fragmentation of the data on a single volume and across multiple volumes can be limited.
- Valuable catalog space and memory-based control block storage can be kept to a minimum.
In summary, IBM Tivoli Allocation Optimizer for z/OS V1.1 can handle both SMS and non-SMS managed DASD data sets. You can maintain control through use of intuitive, flexible, and easy-to-understand rule definitions.
IBM Tivoli Allocation Optimizer for z/OS V1.1 is designed to accommodate needs for maximum uptime and minimum disruption to mission-critical applications.
X37 abend recovery
Controlled reduction of primary space to fit existing available space
This function helps avoid JOB FAILED JCL errors due to insufficient space for primary allocation.
This function is performed during allocation when it is determined that a new data set will cause a JOB FAILED JCL error due to insufficient space for the primary allocation. When an out-of-space condition occurs for a primary allocation, the original allocation will be reduced by a user-specified amount, up to a maximum value, until the allocation is successful.
Reduction of secondary allocation
This function helps avoid job failures that are caused by B37 abends.
This function helps increase the chances for successful job completion when the operating system fails to acquire the secondary allocation amount needed to successfully complete the job. When this situation occurs, a B37 abend can result. During B37 abend processing, this function decreases the secondary allocation to fit in the largest single extent on the volume, and then redrives the space acquisition processing.
Dynamic addition of volumes (DASD)
This function helps avoid out-of-space conditions during end-of-volume processing.
During end-of-volume processing, this function dynamically adds another volume, when the secondary allocation space request cannot be satisfied on the current volume, and properly handles any requisite catalog updates.
X37 abend prevention and avoidance
Automatic addition of secondary allocation if none specified
This function helps avoid job failures that are caused by D37 abends.
This function adds a secondary allocation during D37 processing if no secondary space value has been specified. Data sets that are created with only a primary allocation are not extended when the primary allocation is full; thus, an abend can occur. During D37 processing, this function obtains control and adds a secondary space value (based on a percentage of the original primary allocation amount) if no secondary allocation has been specified.
Release unused data set space
This function automatically releases all, or a portion of, unused space when a data set is closed. This function increases the availability of available space for other tasks in the system.
Secondary allocation quantity reduction to largest free extent
Prior to an attempt to acquire a secondary allocation quantity, this function helps reduce the secondary allocation quantity to the size of the largest free extent. This helps reduce the possibility of the program receiving a space-related abend. It also helps reduce fragmentation of the data set.
Secondary allocation quantity increase
The function increases the amount of the secondary allocation quantity by a percentage of the original secondary quantity starting at a specified extent number. This helps avoid space-related abends by adjusting the allocation quantity upward if an unusual increase occurs in the size of the data set. Unexpected increases in the space requirements of a data set can occur due to incremental growth of the application over time or due to a single, large spike in activity.
Comprehensive activity reporting
IBM Tivoli Allocation Optimizer for z/OS V1.1 provides statistics in a format that can be easily displayed. An online dialog can manage the rule definitions and the active instances of the product. From one Interactive Productivity Facility (ISPF) screen, users can determine the total number of abends and errors that IBM Tivoli Allocation Optimizer for z/OS V1.1 has either avoided or recovered within their system. In addition, summary information is available on the specific number and type of each abend occurrence.
Flexible rule definitions
This feature provides users with flexible, extensive rule definitions that can enable them to specify the data sets to include or exclude (the selection criteria) from IBM Tivoli Allocation Optimizer for z/OS V1.1 processing. By using the associated selection criteria, it also lets users specify the functions (and the values for those functions) to perform when a match is found.
Volume group support
This feature helps users define DASD volume groups from which they can select additional volumes as needed. Users can define volume groups in three ways by:
- Providing an explicit list of volumes
- Providing a name of a volume group that has been defined by a system programmer
- Providing a device type (generic or esoteric), for example, UNIT=3380 or UNIT=SYSDA
Time Sharing Option/Interactive System Productivity Facility (TSO/ISPF) interface
This feature provides an online user interface that allows the user to easily build and manipulate rule definition, volume group, and subsystem option members. In addition, rule and volume group definition syntax can be checked for validity prior to activation. Moreover, users can view and update the status of the product as well as display current statistical information. Many critical commands and functions can be protected using standard security interfaces.
The flexible message facility is responsible for all message handling for batch jobs regarding product processing. It allows the user to determine the actions taken by the product (and the reasons for the actions).
Section 508 of the U.S. Rehabilitation Act
IBM Tivoli Allocation Optimizer for z/OS V1.1 is capable, when used in accordance with IBM's associated documentation, of satisfying the applicable requirements of Section 508 of the Rehabilitation Act, provided that any assistive technology used with the product properly interoperates with it.
Value Unit-based pricing
Value Unit-based pricing will help align the prices of these products to the principle of the PSLC pricing curve, which provides for a lower price per MSU (millions of service units per hour) for larger capacities.
There is also a price benefit when customers grow their capacity. Additional capacity will be based on the number of Value Units (MSUs) the customer has already installed; for example, additional capacity will not be priced starting at the base with a higher price per unit but on the capacity that is already installed.
Note that Value Units of a given product cannot be exchanged, interchanged, or aggregated with Value Units of another product.
IPLA and Subscription and Support considerations
IPLA licenses can be transferred from one machine to another within, but not limited to, an enterprise. The customer may aggregate the capacity for all the processors the product is operated on to achieve a more economic price. This will result in a single Proof of Entitlement. It is the customer's responsibility to manage the distribution of Value Units within the limits of the entitlement of the product license.
Subscription and Support must cover the same capacity as the product license entitlement. Subscription and Support will be available in the country in which the agreement is made.
