FDR procedure
The FDR procedure executes a Fast Database Recovery (FDBR) address space.
Usage
For the FDR procedure, the sum of the values for the CSAPSB and DLIPSB defines the PSB pool size. If PSB is also specified, the larger value (PSB or the sum of CSAPSB and DLIPSB) is used.
If the Fast Path 64-bit buffer manager is being used, the DFSDF= parameter must be specified on the FDR procedure.
Parameters

- ARMRST=
- BSIZ=
- CSAPSB=
- CSLG=
- DBBF=
- DBRCGRP=
- DBWP=

See Parameter descriptions for IMS procedures for descriptions.
DD statements
The following DD statements are valid for the FDR procedure. In addition to the following DD statements, add statements for data sets that are not to be dynamically allocated.
- DFSOLPn DD
- DFSOLSn DD
- DFSWADSn DD
- IMSACBA DD
- IMSACBB DD
- IMSDALIB DD (optional)
- IMSRDS DD
- JCLOUT DD
- JCLPDS DD
- MODBLKSA DD (optional)
- MODBLKSB DD (optional)
- MODSTAT DD
- PROCLIB DD
- STEPLIB DD
- SYSUDUMP DD
Note: The IMSACBA and IMSACBB DD statements must be removed if you want to dynamically
allocate the ACBLIB data sets through the DFSMDA member. The PSBW space is used when OLR is in
progress.
See DD statement descriptions for descriptions.
