Objects that contain recovery information

To recover one object, the RECOVER utility must obtain information about it from another object. Therefore, dependencies exist between catalog and directory objects, and you must recover them in a specific order.

The following table lists the objects from which RECOVER must obtain information.

Table 1. Objects that the RECOVER utility accesses
Object name	Reason for access by RECOVER
DSNDB01.SYSUTILX	Utility restart information. The object is not accessed when it is recovered; a RECOVER job for this object is not restartable, and no other commands can be in the same job step. SYSCOPY information for SYSUTILX is obtained from the log. You can use REPORT RECOVERY to obtain SYSCOPY information for DSNDB01.SYSUTILX.
DSNDB01.DBD01, DSNDB01.SYSDBDXA	Descriptors for the catalog database (DSNDB06), the work file database (DSNDB07), and user databases. A RECOVER job for this object is not restartable, and no other commands can be in the same job step. SYSCOPY information for DBD01 and SYSDBDXA is obtained from the log. You can use REPORT RECOVERY to obtain SYSCOPY information for DSNDB01.DBD01 and DSNDB01.SYSDBDXA.
DSNDB06.SYSTSCPY	Locations of image copy data sets. This table space contains the SYSIBM.SYSCOPY table. SYSCOPY information for SYSTSCPY itself is obtained from the log. You can use REPORT RECOVERY to obtain SYSCOPY information for DSNDB06.SYSTSCPY.
DSNDB01.SYSLGRNX	The RBA or LRSN of the first log record after the most recent copy.
DSNDB06.SYSTSDBA, DSNDB06.SYSTSDBU, DSNDB06.SYSUSER	Verification that the authorization ID is authorized to run RECOVER.
From several of the following table spaces inDSNDB06: SYSTSFAU SYSTSCOL SYSTSTSP SYSTSTPT SYSTSTAB SYSTSIXS SYSTSIXT SYSTSIXR SYSTSIPT SYSTSREL SYSTSFOR SYSTSSYN SYSTSFLD SYSTSTAU SYSTSKEY	Information about table spaces that are to be recovered.
