Recovering an error range or a page
When you select this option, you can recover a range of pages or a specific page.
About this task
This portion of the RECOVER utility offers two options:
- An error range recovery specifies that all pages with reported I/O errors are to be recovered. You should be familiar with specifics about error range recovery before using this option; refer to the Db2 utility guide and reference for your version of Db2.
- If you know the specific page to be recovered, you can specify that page for the recover. This type of recovery should be used only with object profiles containing one object, because the page number is specific to the object.
Both of these recovery options are provided under the error method. When you specify TO method E and Alter method options Y, the Recover Utility Error Options panel appears, as shown in the following figure:

Error range . . . . . . . . Y (Yes/No)
Page number . . . . . . . . 0 (D - Decimal, X - 'hex')
Page continue . . . . . . . N (Yes/No)
Page dsnum . . . . . . . . (D - Decimal, X - 'hex')
The Error Range field specifies the type of error range recovery:
- If you enter Y, the equivalent of RECOVER object ERROR RANGE is specified. This specifies that all pages within the range of reported I/O errors are to be recovered.
- If you enter N, a specific page number will be recovered. You must enter the page number in the Page number field. If you enter Y in the Page continue field, then the recovery continues from the specified page until no I/O errors are detected. In addition, if you want to recover a specific page and the object is a range-partitioned table space with relative page numbering, you must enter the data set number in the Page dsnum field.
