Stand-Alone Loader Utility

The FDR Stand-Alone loader utility (FDRSARLR) can be used to:

Construct a new IPLable copy of SAR. This SAR can be written to the label track of a DASD volume, to unlabeled or standard labeled tape, or can be output in card-image format to any sequential data set.
Modify an IPLable copy of SAR on the label track of a DASD volume.
Modify the defaults for SAR processing (menu) options in the new or updated SAR.
Apply BMC-supplied fixes (“zaps”) to the new or updated SAR.

This utility prints a processing summary map upon completion. This map indicates the location of the SAR program, console options, message defaults, and loader utility options in effect.

SAR support for z14 processor

SAR has supported all architectures from S/360 through ESA/390. Up until now, SAR has run on the IBM Z® in ESA/390 mode. The new IBM z14 processor does not support ESA/390 mode. Therefore, to run SAR on the z14, you must use a new level of SAR. This support is available in Release 05.04.87 SPIN 3 or higher of FDR.

Important

Ensure that you are using the current version of FDRSARLR that contains this z14 support to create the loadable SAR module.

Executing SAR from tape

The SAR program may be IPL’d from unlabeled (NL) tape or standard labeled (SL) tape.

When IPLing from SL tape, the initial program load function (IPL) must be performed five times to bypass the labels. An NL tape requires only one IPL, so it can be loaded much faster. You may create an unlabeled tape containing SAR by using the Stand-Alone loader utility (FDRSARLR). FDRSARLR must be used if you wish to change options or apply fixes.

Executing SAR from DASD

SAR may be IPL’d from DASD, using FDRSARLR to write an IPLable copy of SAR onto cylinder 0, track 0 (the label track) so it occupies no space on the volume. SAR can be written to any DASD volume that does not already contain IPL text (such as the z/OS SYSRES volume or a volume containing the IBM stand-alone memory dump (SAD)). FDRSARLR does not let you accidentally overwrite other IPL text. (Contact BMC Support for instructions if you WANT to overwrite other IPL text on a DASD volume with the SAR program).

Control statements

SAR is distributed with defaults for all options except console addresses. If these defaults do not match your environment all console options and option defaults can be supplied via loader utility control statements. The loader changes the output copy of SAR to have the new defaults.

All option defaults specified on FDRSARLR control statements may be overridden at IPL time. However, if you which to accept certain defaults with no possibility of override, see member $$SAR in the FDR Installation Control Library (ICL) for details. This is especially useful under VM where you may wish to have multiple SAR decks with all options preset, so that SAR starts executing immediately without operator input.

FDRSARLR control statements may also be used to apply fixes to SAR.

Stand-Alone loader security options

FDRSARLR supports security checking if OBJIN or OUTPUT points to a DASD volume (see Security-Options).

If the ALLCALL option has been enabled, a SAF call for class DASDVOL is issued, with ACCESS=READ for OBJIN, or ACCESS=ALTER for OUTPUT. FDRSARLR does not yet support the FDR.NOALLCALL security profile.
