Steps to be followed after importing the images to NBU
In the following example, there is a database called SAMPLE ; the recovery logs are included in the backup image; the database is restored; and the database is rolled forward to the end of backup timestamp.
Step 1
Restore the image on the DB2 client as a file.
Step 2
Filename will have a naming convention as shown below.
e.g. SAMPLE.0.DB2.NODE0000.CATN000.20180523164142.001
Database Name is Sample Instance Name is DB2 Timestamp is 20180523164142 Catalog Name is CATN000
Step 3
Restore the database. The example below restores the database SAMPLE from location in "C:\Backup"
|
> db2 => RESTORE DATABASE SAMPLE FROM "C:\Backup" TAKEN AT 20180627095334 WITH 2 BUFFERS BUFFER 1024 PARALLELISM 1 WITHOUT PROMPTING |
Step 4
Roll the logs forward to the end of the backup to make sure the database is in a consistent state.
|
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. |
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.
