Transcription

1 PRODUCT SHEET CA High Performance Recovery for IMS for z/os CA High Performance Recovery for IMS for z/os CA High Performance Recovery for IMS for z/os (CA HPR) is designed to allow database administrators (DBAs) to recover IMS databases to a specific point in time, minimizing the long-term impact interruptions have on production systems. Overview CA HPR is designed to create change accumulation files, offer extensive recovery analysis capabilities, build recovery jobs, recover IMS databases and rapidly restore access to critical IMS data. Using high-speed technology to access image copies and change accumulations and logs, it recovers the data more quickly and automatically rebuilds the necessary indexes. Business value Many organizations depend on their IMS databases to support business applications 24 hours a day, seven days a week. So when a hardware or software error corrupts a database or breaks access paths, it is critical that databases be quickly and accurately restored. CA HPR for z/os is a versatile, adaptable product that shortens the time needed for IMS database restores and efficiently recovers your database to a point in time before it was corrupted, maximizing data availability in recovery situations.

2 Features Mainframe 2.0 CA HPR has adopted key Mainframe 2.0 features that are designed to simplify your use of CA HPR and helps enable your staff to install, deploy and maintain it more effectively and quickly. CA Mainframe Software Manager : CA Mainframe Software Manager (CA MSM) automates CA HPR deployment and maintenance and removes SMP/E complexities. The Software Acquisition Service helps you more easily move product installation packages and maintenance from CA Support Online directly to your mainframe environment and prepare them for installation. The Software Installation Service standardizes CA HPR installation, which includes a new, streamlined Electronic Software Delivery (ESD) method that allows CA HPR to be installed using standard utilities. This service also provides standardized SMP/E product installation and maintenance via APARs and PTFs, and simplifies SMP/E processing through an intuitive graphical user interface and an intelligent installation wizard. The Software Deployment Service helps you to more easily deploy CA HPR in your mainframe environment. CA MSM Consolidated Software Inventory (CSI) updates and infrastructure improvements add flexibility to CA MSM processing of CSIs and enable CA MSM to more effectively utilize CPU and system memory. The Software Configuration Service helps enable you to more effectively configure CA HPR if it has been acquired, installed, maintained and deployed using CA MSM. Installation Verification Program (IVP) and Execution Verification Program (EVP): As part of qualification for inclusion in the set of mainframe products from CA Technologies released every May, CA HPR has passed stringent tests performed through the IVP and EVP to find and resolve interoperability problems prior to release. These programs are an extension of CA Technologies ongoing interoperability certification initiative launched in May Best Practices guide: This guide provides information on CA HPR installation, initial configuration and deployment to shorten the learning curve for staff who are responsible for the installation and management of this product. Health Checker: The Mainframe 2.0 Health Checker provides CA HPR Health Checks that execute under the IBM Health Checker for z/os. The health check that is provided will verify that the required components of the started task used by the CA Technologies database management products for IMS are running properly. 2

3 What s new in 15.0 IMS version 12: IMS version 12 is now supported. Command Control Manager: A new common component, Command Control Manager (CCM), is provided to help you issue IMS commands in sets and across all the IMS systems in an IMSPlex. ISPF Panel for Historical Reporting: You can view database figures stored in the IMS Information Repository (IIR) through the ISPF interface using the Historical Reporting application. Enhanced Sort Work Data Set Allocation: CA HPR lets you override dynamic allocation of sort work data sets for change accumulation processing. Overriding dynamic allocation of sort work data sets helps you avoid abends on the sort phase of recovery jobs. Key capabilities CA HPR allows DBAs to recover IMS databases to a point in time, minimizing the impact of disruptions on production systems. In addition, the product includes such features as: Database support: Support for SHISAM, HISAM, HIDAM, HDAM, Fast Path DEDB, and High Availability Large Database (HALDB) PHDAM and PHIDAM database structures. Recovery scenarios: With CA HPR, you can specify the recovery scenario that best fits your needs and data availability requirements. In addition to image copies (backups) or an existing database as input to the recovery process, you can optionally include change accumulation files, IMS logs, or both. Databases defined to change accumulation groups (CAGRP), database data set groups (DBDSGRP), database groups (DBGRP), and recovery groups (RECOVGRP), as well as databases in a specified PSB, can be recovered as a group. Recover a single area, a specified set of areas, or all areas in a DEDB. In addition, DEDB Multiple Area Data Sets (MADS) can be replicated during the recovery. You can recover the database to a user-specified point in time. This provides you the flexibility to select the optimum time to use as the recovery time. Any in flight updates will be automatically removed to provide a consistent database recovery. Forward recovery is also supported where an image copy is not used as part of the recovery process. Updates from the IMS logs and/or change accumulations are applied to an existing database to recover the database to a user-specified point in time. Change accumulation: CA HPR includes change accumulation functionality that can be invoked stand-alone or as part of a recovery scenario. 3

4 Your input to change accumulation can be only logs to create a new change accumulation or logs with an existing change accumulation can be specified to create an updated change accumulation data set. Databases defined to CAGRP are accumulated at the same time, providing a consistent change accumulation set for use in recoveries. If no logs or updates exist on the logs selected, the change accumulation process will continue to create a usable accumulation data set. A user-specified point in time can be used as the cut-off time for the accumulation. This enables change accumulation to the optimum time for a required recovery scenario. Any "in flight" updates are automatically removed to provide a consistent change accumulation. Change accumulation supports spill record processing. When performing change accumulation in a data-sharing environment, an incomplete log set causes spill records to be generated. After the missing logs are made available, the spill records are merged with the new logs and a valid change accumulation is completed. Recovery analyzer: Recovery analysis capabilities aid understanding a recovery situation and rapidly creating the desired recovery scenario. The DBRC and RECON functionality uses the ISPF interface to add, delete, and modify DBRC groups. You can also set up the jobs to back up, restore, and clean up the RECON datasets. Cleanup includes processing the DBRC RECON to prepare it for IMS startup and recovery by closing open logs, marking DBDs and Fast Path Areas as "recovery needed," and deleting active SSIDs. Create recovery points by issuing IMS commands (!DBD, /DBR, /CHECKPOINT) for the specified database or database group. When databases are used in a data-sharing environment, the IMS commands will be sent to participating IMS systems. Using the ISPF interface, you can also locate the valid recovery points for a specified time range. The ability to invoke the BMP pause/restart functionality allows recovery analyzer functionality to operate on databases that have active BMPs without waiting for the BMP to complete. The BMP pause/restart will be used to establish recovery points and other recovery related processing by pausing the BMP when CA HPR needs to get exclusive control and automatically restarting the BMP after needed processing relinquishes exclusive control. When preparing for a recovery, you can verify that the needed change accumulation, image copies, and log files are available for the specified recovery (standard, point in time, etc.). After obtaining input data from DBRC, and, if running CATDS, the product will verify that the data sets exist in the catalog. 4

5 Using the ISPF interface, you can set up the job stream needed to execute the type of recovery you desire. The recovery analyzer functionality will also recognize if a virtual image copy was created and automatically include an index rebuild as part of the recovery. Once established, this recovery job can be saved for future use or submitted to perform the recovery. Optimize performance: CA HPR uses a number of techniques to optimize its performance while reducing the impact on the resources used by other IMS activities. When IMS logs are specified as input, change accumulation of the logs is automatically performed, thus putting the database updates in sequential order to decrease recovery time. The change accumulation process reads multiple logs at the same time, reducing the elapsed time for the accumulation process. When you specify that indexes should be rebuilt instead of recovered, CA HPR invokes CA Secondary Index Builder for IMS for high-speed index building. When performing change accumulation, you can process a complete change accumulation group or multiple change accumulation groups in parallel by reading all logs in a single pass. Advanced capabilities: CA HPR includes additional capabilities to increase productivity and enhance performance. The IDCAMS interface provides IDCAMS processing to optionally delete and define VSAM and OSAM database datasets prior to recovery. Normally, you must recover to the same data sets that you backed up; however, CA HPR can restore a database to an alternative set of data sets. This creates a copy of the databases usable for reporting, testing, or other activities. IMS Information Repository (IIR): CA HPR results can be stored in the IIR. You can access this stored information to determine trends, compare threshold values to trigger actions, or do historical reporting. You can view database figures stored in the IIR through the ISPF interface using the Historical Reporting application. Optional feature that is separately installed. Several tools are provided that report on the data stored in the IIR tables. In addition, you can extract the data in the IIR repository for use by other reporting tools. Compatibility modes: BMC compatibility mode allows the use of existing BMC JCL and control statements with minimal or no changes. This minimizes the conversion effort for BMC replacement. The IBM utility compatibility allows execution using the same JCL as the IMS Recovery utility (DFSURDB0) for recoveries and the IMS change accumulation utility when doing a change accumulation. 5

6 Integration with other product from CA Technologies: CA HPR integrates with CA Database Analyzer for IMS for z/os to provide complete pointer checking of the recovered database. Integration with CA Secondary Index Builder for IMS for z/os automates primary and secondary index rebuilding after a recovery. A license for CA Secondary Index Builder is not required to utilize this integration.
