If you use mirrored log volumes (see the log mode setting), volume mirrors can sometimes crash. In this case, the database continues to operate but only the part of the volume pair that is intact can be accessed. The defective mirror volume is shown as a BAD volume.
You can use the Database Manager GUI to restore a damaged mirror log volume.
· When you trigger the recovery of a log volume, it is reinitialized without the data being copied from the intact volume to the recovered volume.
· The system then writes to both log volumes sequentially.
· The volume originally marked BAD must be filled once before the contents of both volumes are identical again and both volumes can be read.
· The defective volume remains BADduring the entire reintegration phase.
The database instance is in the operational state ONLINE.
