RecoverDB2
Steps to be followed after importing the images to NBU.
In the following example, we have a database called SAMPLE. The recovery logs are included in the backup image, the database is restored, and then the database is rolled forward to the end of backup timestamp.
Step 1
Login to the NetBackup GUI navigate to Backup, Archive and Restore.
Step 2
Click on the Restore Files tab and select the Source, Destination Client and type of Policy to restore the DB2 backup files.
Step 3
Restore the image on the DB2 client as a file.
 |
Note: Set Policy Type to standard, as the restore will be as flat files as opposed to DB2. |
Step 4
Set a valid date range to look for the backup image. Make sure to change the Browse Directory to the "/" location, else the contents may not populate.
Step 5
Select the image to recover, and start the restore process back to a location on the client machine.
Step 6
Recovered filename will have a naming convention as shown below.
e.g. SAMPLE.0.DB2.NODE0000.CATN000.20180523164142.001
- Database Name = Sample
- Instance Name = DB2
- Timestamp = 20180523164142
- Catalog Name = CATN000
Step 7
Restore the database. The example below restores the database SAMPLE from location in "C:\Backup"
|
db2 => restore database sample from "C:\backup" taken at 20180919172832 with 2 buffers buffer 1024 parallelism 1 without prompting SQL2540W Restore is successful, however a warning "2539" was encountered during Database Restore while processing in No Interrupt mode. |
Step 8
Roll the logs forward to the end of the backup to make sure the database is in a consistent state.
|
db2 => rollforward db sample to end of backup
DB20000I The ROLLFORWARD command completed successfully. |
Note : If log files are not included in backup images, the rollforward recovery needs to be done as per the method used for backing up logs.
