- Recover to a prior point in time corresponding to the time of FlashCopy

- Reset volumes using FlashCopy, including BSDS and logs

- Restart DB2

- Use transaction SM13 to resolve R/3 units of work

- Recover to a prior point in time using

FlashCopy + logs

- Reset volumes using FlashCopy , but use current BSDS and active logs.

Use CHKFREQ of 15 minutes to keep at least a day worth of checkpoints in the current

BSDS. Make the active log configuration large enough to hold all log records written

between FlashCopy.

Example: FlashCopy every 12 hours. Make sure the same active log data set is not

being reused within 12 hours.

- Requires archive logs from point of FlashCopy

(If the active log configuration is large enough, then archives won’t be required).

- Follow the same steps for Conditional Restart, except specify the LOGONLY option

on the RECOVERY commands

- If using volume-level-copies to re-establish the date and time of the data

(automatically assumes data is being regressed) and then coming forward on the log,

the two points-in-time are; A.) The RBA/LRSN of the log suspend, or consistency

group, when the volume-level-copy was taken, and B.) The point-in-time to which the

database is to be reset to (coming forward on the log, but not all the way to current).

- Use transaction SM13 to resolve R/3 units of work

- Disaster Recovery

- point in time copies, send offsite

- DB2 image copies, send offsite

- disk to disk remote copy mirroring, PPRC, XRC
