There are a few final steps needed before the newly built system may be
IPLed. The MVTSETUP job, in
mvtsetup.jcl, does this. It
contains four steps:
FIXRDR: The supplied region size for the
RDRtask is too small, causing 804/80A ABENDs. The supplied default region size for jobs read by
RDRis too small, as well, and if they ABEND, they take the initiator down with them. This step increases the
RDRregion from 48K to 64K, and the default job region from 50K to 128K.
PRESRES: Remember all those annoying mount messages? This step supplies a member for
SYS1.PARMLIBthat tells MVT the five volumes the system knows about are all reserved and not available for dismounting, and sets appropriate volume use attributes for them all.
SMFDEFLT: SMF was included in the generated system, since HASP requires it. This step changes the default SMF parameters to turn off recording of SMF data to disk, so we don't have to manage it later.
CTLGMVT: This step populates the target system catalog with the datasets that were just created.
SCRTCHUT: This step removes the four
SYS1.SYSUTndatasets used by stage 2. They are no longer needed once that has been completed, and the work space can be freed up for general system use.
We're finished with the driving system. Shut it down:
which should return with:
IEF301I 00E WTR CLOSED P00
then halt the system:
which should return:
IEE334I HALT EOD SUCCESSFUL
At this point, MFT is stopped, and you can safely quit Hercules. If, instead, the system loops, go ahead and quit Hercules anyway; nothing serious will happen.
