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. |
