Experiences With Disaster and Recovery Procedures
Of ADABAS Data on Mainframes

By Dieter W. Storr

Last update: 10 June 2004

Since September 11, the recovery of computer systems and data have became a higher priority. CEO’s are increasing the recovery budgets and training recovery teams at disaster recovery conferences and seminars.

I recently returned from one of our disaster recovery tests at an external site. Even though our contingency plan was well written, up-to-date, accurate, and tested, we failed in some points.

It is relatively easy to back-up ADABAS databases and restore them with protection logs. But what about sequential datasets that are needed as input for some ADABAS utilities? Also, in OPEN system architecture some functions need non-ADABAS data. How can a recovery process handle this?

This presentation will describe how you can back-up ADABAS and system related data, point out the recovery procedures, explain where and how to collect information to recover, and discuss the pros and cons of different approaches.

Additionally, we will look at some experiences from other companies on how they recovered computer operations after September 11.
