Hi all,

I am working on building a new application in the Mainframe Environment.

1. How to decide frequency of the backup (DB2) ? What type of data backup required and its retention period ?

2. How to develop procedures for handling all planned and unplanned outages affecting the database environment ?

Thanks

Is this your first time doing such a task?

Can you model your efforts on an existing, well documented application that does it properly?

Yes, this is the first time.

Oh yeah, I am trying to get reference from existing applications. However, trying to find source (standard documents or url) to understand the basics.

Generally tech support should have a DB2 backup established. Disaster recovery backup/restore needs should be considered as well.

Specific needs for daily/weekly/monthly et al are based upon the online/batch activities and must be considered as to how do you recover/rerun when system/program/job failures occur.

Very general suggestions.

Ask your cohorts or other developers/teams at your site.

You need to check the job scheduling and identify the processes that updates the db2 tables and then have a before and after back up as per the criticality’s of the updates.

You need a full back up for at least have 30 GDGs.
