Application Recovery Tool for IMS and DB2 Databases A Data Recovery Guide

Many businesses to-day have applications that need to access and update data from both DB2 for OS/390 and IMS databases to make critical information instantly available throughout the enterprise. DB2 and IMS both coordinate data changes. However, if users later need to recover both databases to the same point, they must recover data separately dealing with different logs, different utilities and possibly complex recovery scenarios that could be time consuming and error prone. IBM Application Recovery Tool for IMS and DB2 Databases, a recent rename of the previous DB2 Recovery Manager tool, works with either DB2 or IMS or with both. It uses image copies for both databases and establishes synchronization points in each called a Virtual Image Copy to which recovery may be done. It also establishes a quiesce point and notes where the point is located on the respective logs. During recovery, the user specifies the Virtual Image Copy, and Application Recovery Tool applies the appropriate image copies and causes the log to be applied up to this point. Users can also use Application Recovery Tool to automate the recovery of resources. The Tool will generate the Job Control Language, locate the proper image copies and control the execution of jobs for either DB2 or IMS. This IBM Redbook provides an overview of the application recovery capabilities of both IMS and DB2, a detailed description of the IBM Application Recovery Tool for IMS and DB2 Databases, and illustrates through recovery scenarios the operational improvements that the tool can offer.
