IMS Recovery Solution Pack business scenarios
This topic describes business scenarios that demonstrate how IMS Recovery Solution Pack can help reduce your downtime and get your IMS systems back up and running.
Recovering from an application error
If an application error occurs, and point-in time recovery (PITR) is required, you first need to determine which application had the error and when that error occurred.IMS Recovery Expert provides application-level recovery allowing users to recover IMS databases or groups of related databases that represent applications from a system backup or image copies. From the ISPF interface, users create application profiles that include all the IMS databases that represent an application.
When an application needs to be recovered, IMS Recovery Expert analyzes all the available backup resources to generate the Database Recovery Facility JCL to recover all the databases in the application profile.
Making an audit copy of your databases
You can use IMS Recovery Solution Pack to produce an audit copy of your databases.When used in combination, these tools enable you to produce copies without accessing production databases. You can build copies from image copies, change accumulations, and log data sets.
In addition, you can generate data set names by using a prefix or suffix, date, time, high-level qualifier, and literal.
Recovering data after a system failure
The last, but critical, piece of IMS Recovery Solution Pack is the ability to recover your data in the event of a disaster. A typical disaster recovery strategy is based on cost, the amount of time that it takes to recover compromised data, and the ability of your organization to absorb any permanent loss of data.
Typical disaster recovery strategies often involve sending image copies, change accumulations, logs, and RECONs to a remote site. To minimize the amount of data that needs to be sent, as well as the resulting expense and complexity, you can use IMS Recovery Expert to send system-level-backups or use change accumulation as input to create an incremental image copy and send this image copy to a remote site.
Regardless of the amount of IMS High Performance Image Copy data that is sent, IMS Recovery Solution Pack enables you to restore your critical IMS data efficiently and effectively.
