Specify the recover (RECOVER) parameter

After a failure, you must rebuild changed access paths that were not forced to auxiliary storage or journaled with the RECOVER parameter.

To rebuild access paths and to recover data, you can use the RECOVER parameter on the following commands. These commands specify when the access path is to be rebuilt:

Create Physical File (CRTPF)
Create Logical File (CRTLF)
Create Source Physical File (CRTSRCPF)

Note: Access paths are rebuilt either during the initial program load (IPL), after the IPL, or when a file is opened.

Table 1 shows your choices for possible combinations of duplicate key and maintenance options.

Table 1. Recovery options
With this duplicate key option	And this maintenance option	Your recovery options are
Unique	Immediate	Rebuild during the IPL (IPL) Rebuild after the IPL (AFTIPL, default) Do not rebuild at IPL, wait for first open (*NO)
Not unique	Immediate or delayed	Rebuild during the IPL (IPL) Rebuild after the IPL (AFTIPL) Do not rebuild at IPL, wait for first open (*NO, default)
Not unique	Rebuild	Do not rebuild at IPL, wait for first open (*NO, default)

RECOVER parameter tip

A list of files with access paths that need to be recovered is shown on the Edit Rebuild of Access Paths display during the next IPL if the IPL is in manual mode. You can edit the original recovery option for the file by selecting the desired option on the display. After the IPL is complete, you can use the Edit Rebuild of Access Paths (EDTRBDAP) command to set the sequence in which access paths are rebuilt. If the IPL is unattended, the Edit Rebuild of Access Paths display is not shown and the access paths are rebuilt in the order determined by the RECOVER parameter. You only see the *AFTIPL and *NO (open) access paths.
