IMS Recovery Saver Helps Save Time and Resources

Software Announcement
March 17, 1998
Announcement Letter Number: 298-080


Table of Contents:



At a Glance

The use of IMS RS allows:

  • IMS database time stamp recovery to any time without requiring the data outages and performance impacts associated with establishing IMS recovery points.

  • IMS disaster recovery methodologies where archived IMS log data is manually shipped offsite to work in an IMS data sharing environment.

  • Reductions in disaster recovery service restoration times in a non-RSR environment by automatically performing all necessary RECON maintenance operations.

  • Coordinated recovery between IMS databases and DB2 objects, within the constraints of DB2.

Overview

The IMS/ESA (R) Recovery Saver for MVS/ESA (TM) (IMS (TM) RS) conditions a set of IMS logs and an IMS RECON data set to allow IMS databases to be recovered to any date/time stamp in an IMS data sharing or non-data sharing environment.

IMS RS accomplishes all of its functions as a single job step. All log data sets, as well as work files, are dynamically allocated. As a result, IMS RS is very easy to install and execute.

Extensive use is made of MVS (R) multi-tasking facilities, resulting in the maximum amount of parallelism. This use of MVS multi-tasking facilities not only reduces the total execution time of IMS RS, but also takes full advantage of IBM's CMOS technology processors.

IMS RS supports a mixture of both IMS/ESA Version 5 and Version 6 log data sets and is Year 2000 ready.



Intended Customers

  • Customers whose IMS disaster recovery requirements (both data loss and data recovery time) do not justify the resource requirements associated with products and facilities such as electronic log vaulting (IMS/ESA Remote Site Recovery Facility feature) or IBM 3390 remote copy (XRC or PPRC)

  • Customers who have a requirement to recover IMS databases to a prior state and were unable to establish, prior to the need, a valid IMS recovery point for the prior state, or do not wish to incur the IMS data outages associated with establishing a valid IMS recovery point

  • Customers whose disaster recovery requirements include coordinated data recovery between IMS databases and DB2 (R) objects



Key Prerequisites

IMS RS is designed to operate with IMS Versions 5 and 6. The System Modification program (SMP/E) is required for installation.



Planned Availability Date

DESCRIPTION

The IBM IMS/ESA Recovery Saver for MVS/ESA (IMS RS) provides a new process for truncating IMS/ESA log data sets to either a user-specified or system-determined date and time, along with automatic updating and maintenance of a set of RECON data sets.

IMS RS is designed to assist in the recovery of IMS databases in both a disaster recovery environment and in a local time-stamp recovery environment. It can also assist in performing coordinated disaster recovery and local time-stamp recovery with DB2. IMS RS is designed to:

  • Analyze a set of RECON data sets to determine which IMS log data streams were active at the user-specified log truncation date and time. If no log truncation date and time are specified, IMS RS will determine the latest possible log truncation data and time, based on the RECON contents.

  • Copy and truncate the log data sets that were active at the log truncation date and time.

  • Provide a list of all IMS units of recovery (UORs), by IMS subsystem, that require subsequent IMS Batch Backout utility actions. In addition, IMS RS will indicate why the UOR requires action (dynamic backout failure prior to the log truncation point, in-flight UOR at the log truncation point, or in-doubt UOR at the log truncation point).

  • Perform all necessary maintenance operations against the RECONs so that subsequent IMS database recovery operations can fully utilize the capabilities of DBRC.
By performing these functions, IMS RS supports:
  • IMS disaster recovery methodologies that involve the external shipment of IMS log data sets and RECON backups offsite, in both an IMS data sharing and non-data sharing environment.

  • The recovery of IMS databases to any date/time stamp, assuming that the necessary IMS log data sets and image copy data sets are available and known to DBRC.

  • Coordinated disaster recovery between IMS databases and DB2 objects, within the constraints imposed by DB2.

  • Coordinated date/time stamp recovery between IMS database and DB2 objects, within the constraints imposed by DB2.
IMS RS includes a utility which provides single step backup and restore functions for RECON data sets, including those with records that exceed 32,760 bytes in size. This utility is designed to be used in conjunction with the DBRC BACKUP.RECON command.



Year 2000

This product does not have date dependencies and is, therefore, Year 2000 ready.

This product is Year 2000 ready. When used in accordance with its associated documentation, it is capable of correctly processing, providing, and/or receiving date data within and between the 20th and 21st centuries, provided all other products (for example, software, hardware, and firmware) used with the product properly exchange accurate date data with it.



PRODUCT POSITIONING

IMS RS addresses IBM database recovery needs in both a disaster recovery environment and a local recovery environment.

IMS/ESA Versions 5 and 6 offer an excellent disaster recovery facility, the Remote Site Recovery (RSR) feature. The use of RSR can reduce data loss (missing committed database updates) to low, single-digit seconds and can achieve IMS service restoration times (back in business) of single-digit minutes.

However, the use of the RSR feature requires the existence of a continuously-operating IMS system at the disaster recovery site and sufficient communications bandwidth capability to transmit the IMS log data to the disaster recovery site on a real-time basis. In addition, if single-digit minutes service restoration times are desired, DASD must be dedicated at the disaster recovery site to hold shadow copies of the databases.

Not all customers have business requirements that justify the usage of a facility such as RSR and these are the customers who should consider the use of IMS RS as part of their disaster recovery methodology, especially if they are using, or considering the use of, IMS data sharing.

In addition, IMS RS can assist in achieving a coordinated disaster recovery involving both IMS databases and DB2 objects.

One-Time Charge: Customers who pay a one-time charge for a licensed program receive enhancements and future releases, if any, at no additional charge. Significant new function may be offered as an optional feature and charged for separately. If a replacement program is announced and the customer elects to license the replacement program, a time-based upgrade credit may apply.

Variable Charges: The applicable graduated one-time charge or graduated monthly license charge will be based on the group of the designated machine on which the licensed program is licensed for use. If the program is designated to a processor in a group for which no charge is listed above, the charge of the next higher group listed applies.

For upgrades of one-time charge licenses to a machine in a higher group, the upgrade charge will be the difference in the then current charges between the two groups. For downgrades of one-time charge licenses to a machine in a lower group, there will be no adjustment or refund of one-time charges paid.

For upgrades or downgrades of monthly license charge licenses, the monthly license charge applicable to the higher or lower group will apply.

Entry Support License One-Time Charge: One-time charge authorizes use only on IBM Entry End User/390 machines.
