2 Description CICS VSAM Recovery V3R1 (CICSVR) is an automated recovery tool that helps you minimize the loss of VSAM data in the event of software, hardware, or human error. CICSVR uses logs to recover your VSAM data. supports: CICSVR MVS system logger log streams CICSVR SAM copies of MVS system logger log streams CICS/ESA V4 forward recovery logs The CICS system log Up until now, CICSVR was primarily used as a CICS data recovery tool. With this new version, CICSVR also provides recovery for your VSAM batch applications. When enabled, CICSVR VSAM batch logging will log the updates made to the VSAM spheres by batch applications to an MVS system logger log stream. If the VSAM spheres are lost or damaged, CICSVR can use the log records to recreate the spheres. It is essential to be prepared before a disaster happens. With CICSVR, you can take the necessary steps ahead of time to safeguard your data. CICSVR Saves You Time and Eliminates Errors: CICSVR is designed to facilitate the recovery of lost or damaged VSAM data sets through the CICSVR ISPF dialog. You can navigate through the dialogs, selecting the spheres you want to recover and the backups you want to use. Behind the scenes, CICSVR executes jobs such as LOGOFLOGS SCAN to get the latest information on the VSAM spheres from CICS, and DFSMShsm restore or DFSMSdss copy or dump to get the latest backup. Then, the dialogs generate a recovery job that you can submit when you are ready to recover your VSAM spheres. The CICSVR dialogs supply all the details (VSAM spheres, backups, and so on) and you select what you want. It s that simple. Complete Automation for DFSMShsm Backups and DFSMSdss Copies and Dumps: You can use any backup and restore program with CICSVR but if you use DFSMShsm or DFSMSdss, CICSVR provides full automation of your recovery. With full automation, CICSVR displays the latest DFSMShsm backup or DFSMSdss copy or dump for your sphere. If you do not want to use the latest backup, you can get a list of all the DFSMShsm logical backups or DFSMSdss logical copies or logical dumps for that sphere and select the backup that you want from a list. Support for DFSMSdss logical copies and logical dumps is new with CICSVR V3R1. Recovery for Your Batch Updates: CICSVR VSAM batch logging is new with CICSVR V3R1. It requires all systems to be running as a sysplex, with the LOGR policy defined. When enabled, it provides logging for VSAM data sets that are not currently in use by other applications. CICSVR VSAM batch logging uses the new CICSVR server address space to communicate with CICSVR and other DFSMS components. CICSVR VSAM batch logging calls the system logger to write the log records to the MVS system logger log stream. The system logger provides a common logging facility for all z/os and OS/390 images, providing greater 24 x 7 availability in the event that an image fails. The coupling facility enables logging from throughout the sysplex to be directed to a common log stream, if desired. Once the records are logged, CICSVR can use them to recover your VSAM spheres if they are lost or damaged. The VSAM spheres will be returned to the exact state before the data was lost. Reducing Recovery Time: New in this version is the change accumulation feature. Change accumulation significantly reduces the time it takes to forward recover a VSAM sphere. After a backup has been made for a sphere, you can set up a change accumulation batch job so that it is submitted at regular intervals by a workload management product such as OPC/ESA. The change accumulation batch job consolidates the forward recovery log records into a change accumulation data set. Then, when a forward recovery is needed, the change accumulation data set can be used in place of the forward recovery log or log stream; CICSVR only needs to use the forward recovery log or log stream to get the most recent log records (the records that have not yet been consolidated by the change accumulation batch job). Remote Site Recovery: Special emphasis is made in this new version of CICSVR on setting up and maintaining a remote disaster recovery site. New EXPORT and IMPORT commands are introduced to make it easy to copy the essential data in your RCDS so you can send it to your remote site and load it into your remote site s RCDS. Accessibility by People with Disabilities The following feature supports use by people with disabilities: Operation by keyboard alone Euro Currency These programs are not impacted by euro currency. Value Unit Based Pricing Value Unit based pricing will help to 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 be a price benefit when customers grow their capacity. Additional capacity will based on the number of Value Units (MSUs) the customer has already installed, that is, 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/aggregated with Value Units of another product. International Program License Agreement (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

5 CICSVR VSAM batch logging Complete data set forward recovery automation (via the dialog) using DFSMSdss copies and dumps OS/390 V2R10 (5694-A01), with the following APARs (program modifications), is required to take advantage of the new CICSVR functions being introduced with this new release: OW45559 OW47025 OW46161 OW45560 OW44714 OW51544 OW49369 OW49478 OW49529 OW49530 OW50340 OW50341 OW50433 OW51135 OW50683 PQ42845 OW49899 OW48258 OW47781 OW51100 OW50538 OW47574 OW48701 OW51555 The following CICS TS (5697-E93) and CICS V4 ( ) APARs are required to take advantage of the new CICSVR VSAM batch logging function: PQ50896 PQ50900 PQ50901 Compatibility: If you are migrating from an earlier release level of CICSVR, you should perform some migration actions, including a conversion of the RCDS. These migration actions should be performed when you have successfully completed SMP/E APPLY and ACCEPT of CICSVR. To maintain the existing forward recovery capability for VSAM spheres, when migrating from CICSVR/MVS V2R3 to CICSVR V3R1, minor changes must be made to the JCL jobs and error exits. Refer to CICSVR Implementation Guide for more information on the migration utility. If you are migrating to CICSVR V3R1 from a release prior to CICSVR V2R3, refer to Chapter 4 in CICSVR MVS/ESA Implementation Guide V2R3 for details. CICSVR V3R1 is fully upward compatible with CICSVR V2R3. CICSVR V3R1 supports CICS TS V1, or later and CICS V4 (CICS/ESA ) forward recovery logs. CICSVR V3R1 does not support forward recovery of a CICS TS or a CICS V4 VSAM data set using a CICS Autojournal. CICSVR V3R1 and CICSVR V2R3 can coexist in the same MVS system, if they have different RCDS data sets and are in separate libraries. The RCDS data set is different between CICSVR V3R1 and previous releases. A migration utility included with the product will convert an existing RCDS from CICSVR V2R3 to CICSVR V3R1 format. These actions are described under section Migrating your RCDS from CICSVR V2R3 to V3R1 in the CICSVR V3R1 Implementation Guide, SH Performance Considerations: Performing a forward recovery using a change accumulation data set can significantly reduce the time it takes to forward recover a VSAM sphere when compared to performing a forward recovery without a change accumulation data set. The table that follows shows the reductions that were observed when a log containing one million log records was processed; of these one million log records, 800,000 updates were made to 200,000 records. As an example of how to read the table, consider the KSDS row in Table 1. This row shows that when performing a forward recovery using a change accumulation data set, elapsed time was reduced 87% and CPU time was reduced 57% when one million log records were processed and 800,000 of the updates were made to 200,000 records. Table 1 CICSVR V3R1 forward recovery: % improvement with change accumulation % improvement without change accumulation VSAM data set type Elapsed Time CPU Time KSDS 87% 57% ESDS 93% 68% RRDS 93% 62% VRRDS 85% 59% Test Environments Performance measurement test runs for CICSVR V3R1 with change accumulation and CICSVR V3R1 without change accumulation were completed using the same test environments. The test environments included: One million CICS V4 forward recovery log records OS/390 V2R10 All measurements were run on an IBM 9672 Model RX6 (G5) in a stand-alone OS/390 environment. All of the log records resided on IBM RAMAC 9392 connected to an IBM storage control unit. The actual performance characteristics that may be experienced by any specific user or for any specific VSAM data set depends on many factors, including the number of updates made per record in the VSAM file. So, the results may differ from user to user. In general, the more updates made per record, the greater the improvement will be when a change accumulation data set is used in the forward recovery. IBM does not represent nor warrant that users will experience the same changes in performance characteristics observed in these examples.
