The data recovery specification designates the title of the DATARECOVERY code file for the database. The following diagram illustrates the syntax for specifying the DATARECOVERY code file:

<data recovery specification>

── DATARECOVERY ── = ──<file title>────────────────────────────────────┤

Explanation

The file title can include a usercode and an ON <family name> specification. If the data recovery specification is not specified, the default title for the DATARECOVERY code file is SYSTEM/DMDATARECOVERY. However, it is recommended that this file title be explicitly specified.

Family substitution occurs at run time for this title.

This file title is contained in the control file. At run time, the title is used to initiate the correct version of the software. Both the usercode of the running task and the family substitution have an effect on which version, if any, of the software is found.

Example

The following statement defines the name of the DATARECOVERY code file as SYSTEM/DMDATARECOVERY. The code file is located under the USER1 usercode on the PACK1 pack.

DATARECOVERY = (USER1)SYSTEM/DMDATARECOVERY ON PACK1;
