Running a restore function
With the CRUISE restore function, you can restore data from tape for database recovery.
Before you begin
Procedure
-
Enter the ZTMNT command to mount the tape that the data is restored
from.
The following example shows that the BFA tape is mounted for this restore function.

Enter the ZFCRU START command to verify and display the parameter table
values.
In the following example, the values in parameter table TABLE1 are verified and displayed.

If the parameter table values pass verification, enter the ZFCRU START
command again to start the restore function.
In the following example, the restore function is started for TABLE1.

When CRUISE restore processing is completed, the state changes to inactive or warning.
What to do next
If the REBUILD option was specified for restore processing, ensure that you pack the restored subfiles to improve system performance and avoid CRUISE backward chain validation errors. The pack operation also rebuilds indexes for files that use B+Tree and block indexing.
